Arizona Builder Warranty Guide 2026: ARS §12-1361 Right to Repair, 10-Year Structural & What Builders Won't Tell You

ARS §12-1361 — Arizona's Right to Repair Law: The Foundation

Arizona's Right to Repair statute (ARS §12-1361 through §12-1365) is the bedrock legal framework for all new construction warranty disputes and home defect claims in Arizona. Before you close on any Phoenix metro new construction home — whether from D.R. Horton, Lennar, Pulte, Taylor Morrison, Meritage, Shea, Toll Brothers, or any other builder — you should understand what this law gives you.

The Three Warranty Periods Under ARS §12-1361

What ARS §12-1361 Does NOT Cover

• Normal wear and tear (carpet, paint, caulking from regular use)
• Damage caused by buyer modifications or negligence
• Pre-existing conditions the buyer accepted "as-is"
• Damage from natural disasters not related to construction defects
• Equipment failure due to normal end-of-life (vs. defective installation)
• HOA common area defects (those are HOA's warranty claims against the developer)

The Pre-Litigation Notice Requirement (ARS §12-1363)

A critical procedural step that many buyers don't know about: before you can file a lawsuit against a builder for construction defects in Arizona, you must complete a mandatory pre-litigation notice-and-repair process:

1. Written notice to the contractor: Send a written notice (certified mail, return receipt requested) describing the alleged construction defect in detail. The notice must identify the location of the defect, its nature, and the damage it has caused.
2. 60-day response window: The contractor has 60 days from receipt of notice to: (a) inspect the property and propose a repair plan; (b) offer a cash settlement in lieu of repair; (c) deny that a defect exists; or (d) do nothing (which constitutes a waiver of their right to repair).
3. Inspection access: You must provide reasonable access for the builder's inspection team. Denying access can hurt your claim.
4. Response evaluation: If the builder offers to repair, evaluate the proposed scope carefully. Is the repair adequate to fully address the defect? Will it be done in a workmanlike manner? Will you receive documentation?
5. Right to reject: You can reject an inadequate repair offer and proceed to litigation if the offer doesn't fully address the defect or is not accepted within a reasonable timeframe.
6. Litigation if unresolved: If the builder doesn't respond, denies the claim without justification, or makes an inadequate offer, you may file suit in Maricopa County Superior Court for the cost of repair, diminution in value, relocation costs, and attorney fees.

The Builder's Express Warranty Program: 1-2-10

Independent of and in addition to ARS §12-1361's statutory protections, virtually all major Phoenix metro production builders provide a structured express warranty program. Understanding how these two layers interact is critical.

Common New Construction Defects in Arizona

The Phoenix metro's unique climate — extreme heat, low humidity, monsoon moisture, expansive clay soils, high UV radiation — creates a specific defect profile for new construction homes that differs from defect patterns in other parts of the country. Here's what to watch for:

Post-Tension Slabs — The Most Critical Arizona-Specific Issue

Post-tension concrete slabs are used in approximately 90% of new single-family construction in the Phoenix metro. This is the dominant foundation type because it performs well in Arizona's expansive clay soils, which swell and shrink with moisture changes.

How Post-Tension Slabs Work

A post-tension slab is poured with steel cables (tendons) running through plastic sleeves cast inside the concrete. After the concrete cures to sufficient strength (typically 48–72 hours), a hydraulic jack applies tremendous tension to each tendon — typically 25,000–35,000 pounds of force per tendon. The jack then anchors the tendon in tension, and the pocket is grouted. The result: the concrete slab is under constant compression, which prevents cracking and improves structural performance.

How to Identify Your Slab Type

• Look for orange or gray plastic "button" anchors in the garage floor and perimeter — these are where the tendons were tensioned
• The inspection report from your new construction or resale inspection should note slab type
• Ask the builder directly — they will tell you; it's in the construction specs
• Most Phoenix metro new construction built since 1990 uses PT slabs

Post-Tension Slab Cracks: What's Normal vs. What's a Red Flag

• Normal: Hairline cracks (<1/16 inch wide) running through tile grout lines; these are normal concrete shrinkage cracks
• Normal: Minor cosmetic cracks in the garage floor (unfinished concrete garages are more prone to surface cracking than interior slabs with tile/flooring)
• Red flag: Cracks wider than 1/8 inch, particularly with vertical differential (one side higher than the other) — indicates differential settlement
• Red flag: Cracks that run through door frames, causing doors to stick or not latch — indicates slab or framing movement
• Red flag: Stair-step cracking in exterior stucco or brick that corresponds to slab cracks — indicates settlement
• Red flag: Any crack that is growing or widening over time (photograph with a coin for scale at different dates)

If you observe any red flag crack patterns, contact a licensed structural engineer (not a foundation repair company with a conflict of interest) for an independent evaluation. Then file a warranty claim with the builder immediately. Structural claims have a 10-year window, but the sooner you act, the better your position.

Stucco Water Intrusion — Silent and Expensive

Most Phoenix new construction uses a stucco exterior — either traditional three-coat hard coat stucco or modern synthetic/EIFS stucco. Stucco is durable, energy-efficient, and aesthetically dominant in the AZ market. However, stucco water intrusion at penetrations is one of the most common and most expensive warranty defects in Arizona new construction.

Primary Failure Points

• Window penetrations: The joint between the stucco and window frame requires proper flashing, caulking, and a weather-resistant barrier (WRB) behind the stucco. If this detail is not correctly executed during construction, water from monsoon rain can enter the wall cavity at the window frame
• Electrical box penetrations: Exterior outlets, hose bibs, and dryer vent penetrations require proper flashing collars and caulking. A missing or improperly installed flashing collar creates a direct water entry path into the wall
• Plumbing penetrations: Exterior hose bibs, gas meter penetrations, exterior shower connections — all require proper sealing
• Roof-to-wall intersections: Where the roof deck meets the exterior wall (particularly at second-floor dormers, balconies, and where a flat porch roof abuts the main structure) — one of the highest-risk water intrusion locations
• Stucco cracks at penetrations: Stucco tends to crack at stress concentrations around penetrations. A crack that's merely cosmetic can quickly become a water entry point

Why This Matters So Much in Arizona

Arizona's monsoon season (July–September) brings brief, intense rainfall events — often 0.5–2 inches in under an hour, accompanied by strong winds that drive water horizontally against building facades. This creates hydrostatic pressure conditions that can force water through even small gaps in stucco. Combine this with Phoenix's extreme heat that cycles caulking through rapid expansion and contraction, and you have a recipe for accelerated sealant degradation.

Water that enters a wall cavity in a wood-frame home (which is virtually all Phoenix new construction) can cause:

• Mold growth within 48–72 hours in a warm, moist cavity (remediation: $3,000–$25,000+)
• Wood framing rot at window bucks, sills, and structural members ($5,000–$40,000+ for significant structural rot)
• Drywall damage (bulging, staining, crumbling)
• Insulation saturation (reduces R-value; creates ongoing moisture reservoir)

HVAC Defects — Arizona's #1 Mechanical Concern

In Arizona, HVAC is not a luxury — it is a life-safety system. An HVAC failure during July in Phoenix, with temperatures exceeding 115°F, is a medical emergency for vulnerable household members. This is why HVAC installation quality deserves extra scrutiny in Arizona new construction.

Common New Construction HVAC Installation Defects

• Undersized equipment: HVAC sizing is determined by a Manual J load calculation — an engineering analysis of the home's heat gain and loss. If the builder's HVAC subcontractor cuts corners on the Manual J and installs undersized equipment, the system runs continuously, struggles to maintain set temperature during peak summer, fails prematurely, and uses far more electricity than a properly sized system. Signs: can't maintain temp below 80°F with system running constantly on a 115°F day.
• Ductwork leakage: Arizona code requires duct systems to be tested for leakage (duct blaster test). Leaky ducts waste 20–40% of conditioned air into unconditioned attic space — dramatically increasing cooling costs. Improperly sealed duct connections at registers and air handler connections are common issues.
• Improper refrigerant charge: An HVAC system that's not charged to the correct refrigerant level (both too high and too low are problems) operates inefficiently, causes premature compressor wear, and can freeze the evaporator coil. This is a startup commissioning issue that should be caught during the builder's final walkthrough — but often isn't.
• Attic insulation inadequacy: Arizona's building code requires R-38 attic insulation minimum; some energy codes require R-49+. Insufficient attic insulation forces the HVAC system to work against enormous radiant heat gain from the roof, increasing operating costs and equipment wear. Check insulation depth at the attic access during your 11-month inspection.
• R-410A phase-out impact: As of January 2025, new HVAC equipment uses R-454B or R-32 refrigerant (the EPA's phaseout of R-410A for new equipment is complete). If your new construction home was built in 2023–2024, it may have one of the last R-410A systems. R-410A is still available for service but at increasing cost. Systems installed 2025+ use the new refrigerants — confirm your system type and store the documentation for future service calls.

Window and Door Installation Issues

Window and door installation is one of the leading sources of new construction warranty claims in Arizona. Common issues:

• Improper flashing: The flashing behind the window frame (integrating with the weather-resistant barrier) is the primary defense against water intrusion. Flashing installed incorrectly or out of sequence creates pathways for water to enter the wall cavity even if the exterior caulking looks perfect.
• Stucco crack at window corners: The four corners of window openings are stress concentration points in the stucco. Small cracks at window corners are extremely common and extremely important — they can allow water entry directly behind the window frame. Seal every window corner crack as soon as it appears; submit it as a warranty claim in year 1.
• Window and door operation: Sticking doors, windows that don't lock, windows that rattle in the frame, sliding doors that derail — all common year-1 warranty items. Submit them all before month 12.
• Low-E glass coating: Arizona new construction should have Low-E (low emissivity) glass to reject solar heat gain. Verify your windows are Low-E by looking for the NFRC (National Fenestration Rating Council) label on the glass or window frame. Windows without Low-E in Arizona significantly increase cooling loads.

Caliche — The Arizona Soil Challenge

Caliche is a hardened calcium carbonate (calcite) layer found in many Arizona desert soils, typically 6 inches to several feet below the surface. It's rock-hard and resistant to water infiltration.

How Caliche Affects New Construction

• Drainage issues: If the builder didn't properly break through a caliche layer during site grading, subsurface drainage may be impaired. This can cause pooling in the yard after rain and create moisture pressure against the foundation.
• Landscaping challenges: Caliche can make tree planting difficult or impossible without expensive breaking/removal. Deep-rooted trees planted without breaking through caliche can fail structurally, as roots can't access lower soil layers.
• Pool and spa excavation cost: If you plan to add a pool, caliche removal adds $2,000–$8,000 to excavation costs compared to non-caliche soil. Some lots are "easy dig" (no caliche) and some are "hard dig" (significant caliche) — ask the builder's sales team before purchasing and before planning a pool.
• Post-installation drainage: New homeowners who install landscaping without accounting for caliche can inadvertently create ponding areas that push water toward the foundation — a long-term risk to stucco, foundation waterproofing, and the PT slab moisture environment.

Zinsco and Federal Pacific Electrical Panels — Red Flags in Resale

While new construction homes won't have these panels (they're banned in new construction), buyers who are also evaluating resale homes should know:

• Zinsco/GTE Sylvania panels: Made through the 1970s; breakers are known to fail to trip on overload/short circuit, creating fire hazard; identified by a distinctive colorful breaker configuration
• Federal Pacific Electric (FPE) Stab-Lok panels: Common in homes built 1950–1980; breakers have documented failure-to-trip issues; associated with thousands of house fires
• If present: Negotiate panel replacement as a condition of purchase; home insurance companies may refuse coverage or add surcharges; most lenders require replacement before closing

The 11-Month Home Inspection — Ryan's #1 New Construction Buyer Advice

If you take only one thing from this guide, make it this: schedule a professional home inspection at the 11-month mark after closing on any new construction home in Arizona. No exceptions.

Why Builders Hate (and Fear) the 11-Month Inspection

The 11-month inspection is such a powerful tool that several builders have started including language in their purchase contracts attempting to limit or discourage it. Read your contract carefully. In most cases, you have an absolute legal right to have your home professionally inspected at any time. Any builder language attempting to prevent you from hiring an independent inspector during your ownership should be reviewed by an attorney.

Here's why builders take the 11-month inspection seriously: a well-qualified home inspector working an 11-month-old house typically identifies 15–45 individual warranty items, many of which the builder hoped would go unnoticed until the warranty expired. The aggregate repair cost of these items often runs $2,000–$15,000 — all of which the builder must address at no cost to you. That's a significant expense the builder avoids if buyers don't conduct the inspection.

What a Good 11-Month Inspector Looks For

Choosing Your 11-Month Inspector

Arizona does not license home inspectors — a fact that often surprises buyers. Any person can call themselves a "home inspector" in Arizona without any certification, training, or testing. This makes credential checking especially important.

• ASHI (American Society of Home Inspectors): Requires passing a nationally standardized exam, completion of 250 inspections, and ongoing continuing education. ASHI members are bound by a code of ethics.
• InterNACHI (International Association of Certified Home Inspectors): Requires passing online exams, continuing education, and adherence to a standards of practice. InterNACHI inspectors include many of the most active and experienced inspectors in Arizona.
• Fee range: $350–$600 for a standard single-family home in the Phoenix metro; $600–$1,000 for homes over 3,500 square feet or with multiple structures
• Specialty inspections: Consider adding: sewer scope ($150–$250) even on new construction (installation errors happen), thermal imaging for moisture detection ($100–$200 add-on), and pool inspection if applicable ($100–$200)
• Ask for new construction experience: Some inspectors specialize in new construction; their familiarity with production builder construction methods often results in more items identified

Keeping Your Warranty Log

Documentation is everything in warranty enforcement. A well-maintained warranty log transforms a "he said/she said" dispute into a documented timeline that supports your legal position.

What to Record in Your Warranty Log

• Date warranty request submitted (screenshot or email confirmation)
• Method of submission (online portal ticket number, email, phone call with notes)
• Description of defect (location, nature, severity)
• Photographs: date-stamped before photos with something for scale (tape measure, coin)
• Builder's response: date received, person contacted, proposed resolution
• Repair date and description of work performed
• After photos documenting completed repair
• Any written communications confirming repair scope and completion

Registering Manufacturer Warranties — Time-Sensitive Tasks After Closing

1. HVAC registration (most urgent): Locate the model and serial number plates on both the indoor air handler and outdoor condenser unit. Register at the manufacturer's website (Carrier: carrier.com, Trane: trane.com, Lennox: lennox.com, Rheem: rheem.com, American Standard: americanstandardair.com). Unregistered = 5-year parts warranty. Registered = 10-year parts warranty. That's a $2,000–$5,000 difference in future service cost.
2. Water heater: Register at the manufacturer's website (Bradford White, Rheem, AO Smith). Most have 6-year tank warranty unregistered; registration can extend to 10+ years on some models.
3. Kitchen appliances: Dishwasher, range, microwave, refrigerator (if included) — register each at the respective manufacturer's website. Most provide 1-year parts and labor; some offer extended parts coverage on major components.
4. Garage door opener: Register with the manufacturer (Chamberlain/LiftMaster, Genie, Craftsman). Most provide 3-year motor warranty that may extend with registration.
5. Roofing: If your builder used a manufacturer-backed roofing system (GAF, Owens Corning, CertainTeed), registration may be required to activate the manufacturer's warranty beyond the builder's own warranty. Ask your builder what roofing system brand and warranty program was used.
6. Structural warranty certificate: Obtain the third-party structural warranty certificate (2-10 Home Buyers Warranty or similar) and store it with your closing documents. If you sell the home, this transfers to the next buyer — it's a valuable selling point and should be listed as a feature in any future listing.

What to Do When Your Builder Refuses to Honor the Warranty

Despite clear statutory protections, builders sometimes deny legitimate warranty claims. Here's the escalation path:

Level 1: Internal Escalation Within the Builder

The first step is rarely the warranty technician — escalate internally:

• Community warranty manager: Escalate from front-line tech to the community's warranty manager in writing (email is fine for documentation)
• Division warranty director: If the community manager doesn't resolve it, contact the builder's division (Arizona) warranty director. For D.R. Horton, Lennar, Pulte, etc., this person exists and can override field-level decisions
• Online reviews: Posting a factual (not inflammatory) Google or BuilderRate review describing an unresolved warranty issue sometimes generates rapid builder response. Builders monitor their online reputation carefully

Level 2: Arizona Contractor Licensing Board (ROC)

The Arizona Registrar of Contractors (ROC) licenses all residential contractors in Arizona, including production builders. The ROC has authority to:

• Investigate complaints against licensed contractors
• Order corrective work
• Fine or suspend contractor licenses
• Access the Recovery Fund (up to $30,000 per homeowner, $200,000 per contractor per year) to compensate homeowners when a licensed contractor fails to perform ordered corrective work

Filing an ROC complaint is free, does not require an attorney, and creates an official record. The threat of ROC action motivates many builders to resolve disputes before the complaint is adjudicated. File at azroc.gov.

Level 3: ARS §12-1363 Formal Notice

Send the statutory written notice under ARS §12-1363 via certified mail, return receipt requested. This formally starts the 60-day clock and creates an official legal record. The notice should be specific about:

• The location and nature of the defect
• The damage caused by the defect
• Your expectation of repair or settlement within 60 days
• Your intent to pursue legal remedies if not resolved

Many construction defect attorneys offer a free initial consultation and will draft this notice for you or review your draft. The notice alone often prompts builder resolution.

Level 4: Litigation in Maricopa County Superior Court

If the ARS §12-1363 process fails to produce adequate resolution, you may file suit. Key points:

• Small claims (Justice Court): Claims under $3,500 can be filed in Justice Court (limited for most construction defects)
• Superior Court: For larger defect claims; typically require attorney representation for best outcomes
• Attorney fee recovery: ARS §12-341.01 allows the prevailing party to recover attorney fees in contract disputes — a significant lever that motivates builders to settle reasonable claims
• Expert witnesses: Structural engineers, licensed contractors, and HVAC specialists typically serve as expert witnesses in construction defect litigation; their fees are part of your damages claim
• Timeline: Arizona Superior Court construction defect cases often resolve in 12–24 months through the litigation process

Ryan Moxley's New Construction Buyer Checklist

Before you sign a purchase contract with any Phoenix metro builder, Ryan recommends covering these points:

At Contract Signing

• Request and read the full express warranty document before signing — don't rely on the salesperson's verbal summary
• Confirm third-party structural warranty coverage and the insurer name
• Ask about CFD (Community Facilities District) assessments and get the annual amount in writing
• Ask about HOA fees — both the primary subdivision HOA and any master association
• Confirm that you have the right to hire an independent inspector at any time during and after construction
• Ask if the builder uses post-tension slabs (almost certainly yes); get the engineering stamp for the foundation design

At New Home Orientation / Blue Tape Walk

• Take your time — this is your last scheduled opportunity to identify issues before closing; don't rush it
• Bring this checklist and go room by room
• Test every window (open, close, lock), every door (operation, latch, deadbolt), every outlet (bring a circuit tester), every light switch
• Run every faucet; check under every sink cabinet for drips or moisture
• Mark every item with blue painter's tape (the standard blue tape walk process)
• Photograph every blue-tape item
• Get the superintendent's signature on a punch list acknowledging all items found; this is your day-1 warranty documentation

Days 1–30 After Closing

• Register all manufacturer warranties (HVAC, appliances, water heater) — time-sensitive!
• Get your structural warranty certificate if not received at closing
• Set a calendar reminder for month 11 — "Schedule 11-Month Home Inspection"
• Document the condition of every room with a photo walkthrough stored in a dated folder
• Locate your clean-out access for the sewer line — you may need it later for a sewer scope

Month 11 — The Critical Window

• Hire an ASHI or InterNACHI-certified inspector with new construction experience
• Authorize a hose test at all window penetrations and exterior interfaces
• Submit every identified item to the builder's warranty portal within 48 hours of receiving the inspection report
• Follow up in writing if any items are not acknowledged within 7 days
• Do not allow the 12-month anniversary to pass without all items either resolved or formally disputed in writing

Arizona New Construction Tax and Legal Considerations

Sales Tax on New Construction in Arizona

Arizona imposes a Transaction Privilege Tax (TPT) on new construction contractor revenue. This is essentially a sales tax on the construction materials and labor. In most new construction purchases, this tax is embedded in the purchase price — but buyers should understand it:

• TPT applies to the builder's cost of materials; it's passed through to the buyer in the form of the purchase price
• Arizona TPT rates vary by city/county: Maricopa County base rate + city rate = 6.3–9.5% total TPT depending on location
• Unlike buying an existing home (no sales tax on real estate), new construction effectively includes embedded TPT in the price
• For buyers: this is generally not a separate line item; it's built into the builder's pricing model

ARS §36-1681 — Arizona Pool Barrier Law

If your new construction home includes a pool, or if you plan to add a pool later, Arizona law requires a pool barrier:

• ARS §36-1681 requires an enclosure around all swimming pools that prevents unsupervised access by children under age 6
• Minimum fence height: 60 inches (5 feet) measured from the outside
• Self-closing, self-latching gates required on all openings
• If the home's exterior wall forms part of the barrier, door alarms or pool alarms may be required
• Violation of pool barrier law can result in civil liability if a child drowns — this is taken extremely seriously in Arizona
• Insurance implication: Homeowner's insurance policies typically require pool barrier compliance; verify your policy

Ryan Moxley — New Construction Buyer's Agent

Buying new construction in Phoenix metro without buyer representation is a mistake Ryan sees buyers make regularly. Here's what happens without an agent:

• The on-site sales representative works for the builder — not you. Their job is to maximize the builder's revenue and protect the builder's interests.
• Without an agent, you negotiate directly against a professional salesperson who knows the builder's true cost basis, which communities are moving slowly, what incentives are actually available, and which items have room for negotiation.
• Builder incentives (rate buydowns, closing cost contributions, design credits) are often only presented to buyers with representation, because agents keep builders accountable to their publicly offered incentive programs.
• Ryan's representation is typically free to buyers in new construction transactions — the builder pays the buyer's agent commission from their marketing budget. You get professional representation at no additional cost.

Post-Tension Slabs in Arizona: The Complete Homeowner Guide

Post-tension concrete slabs are the dominant foundation type in Phoenix metro new construction, yet they remain poorly understood by most homeowners. A thorough understanding of post-tension slabs is essential for every Arizona new construction buyer because improper handling of these slabs is the most expensive avoidable mistake in Arizona homeownership.

What Is a Post-Tension Slab?

A post-tension slab is a concrete slab that contains high-strength steel cables (tendons) embedded within it under significant tension. The cables are typically 1/2-inch diameter high-strength steel strands, tensioned to approximately 33,000 pounds of force. After the concrete is poured and cures to sufficient strength (typically 75% of design strength, or about 3 days), the cables are tensioned using hydraulic jacks and then anchored at the slab edges. The combination of concrete (strong in compression) and tensioned steel (providing the necessary tensile strength) creates a composite system that is significantly stronger and more crack-resistant than conventionally reinforced slabs of the same thickness.

Why post-tension slabs dominate Arizona: Arizona soils — particularly the expansive clays and variable caliche layers common in the Phoenix metro — create challenging conditions for foundations. Post-tension slabs can span over weak soil areas and accommodate minor differential soil movement much better than conventional rebar-reinforced slabs of the same depth. They also allow thinner slab designs (typically 8–10 inches thick for residential PT vs. 12–16 inches for conventional) that are cost-effective for builders.

The Cardinal Rule: Never Cut, Drill, or Core a Post-Tension Slab Without Engineering Approval

This rule cannot be overstated. A post-tension cable under 33,000 pounds of tension stores enormous energy. If a cable is severed during drilling or coring:

• The released energy causes the cable to whip violently and can cause serious injury or death to workers
• The structural integrity of the slab is permanently compromised in that area
• Repair requires accessing both ends of the cable and re-tensioning — a major, expensive, structurally invasive repair ($10,000–$40,000+)
• Multiple severed cables can require entire slab section demolition and replacement

When you MUST penetrate a post-tension slab (pool installation, plumbing retrofit, concrete cutting for any reason), the required process is:

1. Order a GPR (Ground Penetrating Radar) scan of the slab in the work area to locate all cables
2. Have a structural engineer review the scan results and approve a penetration plan that avoids all cables
3. Use only the engineer-approved penetration locations
4. Have the work inspected if the engineer requires it

Cost of proper cable locating: $400–$1,200 for a GPR scan from a qualified provider. This is a negligible cost compared to the $10,000–$100,000+ repair cost if a cable is severed, and the potential for serious injury to contractors. Do not allow any contractor to begin concrete cutting without producing a GPR scan and engineer approval. Any contractor who says "I do this all the time, we’ll be fine" should be immediately dismissed.

Post-Tension Slab Inspection: What to Look For

During your phase inspections (particularly Phase 1 pre-pour and Phase 2 pre-drywall), and in your ongoing homeownership, the following post-tension slab conditions warrant attention:

• Tendon end caps: At the edge of the slab, each tendon should be covered with a protective pocket cover (plastic or metal cap) filled with grout or epoxy to prevent corrosion of the exposed cable end and anchor plate. Missing or damaged pocket covers are a warranty item. Corroded anchor plates can lead to cable failure over time.
• Slab-edge cracking: Some hairline cracking at the slab edge is normal. Large cracks, stepped cracks (where one section is higher than adjacent), or active cracks (widening over time) warrant engineering evaluation.
• Interior slab cracks: Minor controlled cracking within the slab interior is expected in post-tension construction. However, wide cracks (>1/8 inch), cracks with differential elevation (one side higher than the other), or diagonal cracks in corners of rooms can indicate slab movement beyond normal expectations and may warrant structural engineer evaluation.
• Floor elevation differences: Use a 4-foot level to check floor elevation consistency across rooms. Significant differences (>3/8 inch per 10 feet of span) in floor levels can indicate differential slab settlement and may be a 10-year structural warranty claim.
• Sticking doors and windows: Doors or windows that progressively stick worse over time (rather than having always had a slight bind) can indicate slab movement that is racking the door or window frames. This is a potential structural warranty claim indicator.

Arizona Monsoon Season and New Construction Warranty Claims

Arizona’s monsoon season (officially June 15 through September 30) is the primary stress test for new construction building envelopes. The combination of high winds, intense rainfall in short bursts, blowing dust (haboobs), and extreme temperature swings reveals waterproofing and sealing defects that no other season exposes. The first monsoon season after closing is your most important warranty discovery period.

What to Document During Monsoon Season

During and immediately after every significant monsoon event, conduct a rapid interior walkthrough looking for:

• Water intrusion at windows and doors: Check around all window and door frames for any moisture, staining, or wet drywall. Even small stains that dry completely are evidence of intrusion that you should photograph with the date and correlate to the specific rain event.
• Roof deck and flat roof ponding: If safe and accessible, check flat or low-slope roof areas for standing water more than 48 hours after a rain event. Ponding indicates inadequate drainage slope and is a warranty claim.
• Garage and entry area water infiltration: Water running under garage doors or entry door weather stripping during hard-driven rain indicates improper sealing or thresholds and is a workmanship warranty claim.
• Basement or subgrade moisture: Arizona homes rarely have basements, but homes with split-level construction or any below-grade space should be checked for moisture intrusion after monsoon events.
• Exterior stucco: Walk the perimeter of the home after rain and look for: new cracks (compare to pre-monsoon photographs), water staining running down from window frames or parapet tops, and any bubbling or soft spots in the stucco that indicate moisture trapped behind it.
• Skylight and chimney leaks: These are common sources of water intrusion — inspect ceiling areas below them immediately after rain events.

Documenting correctly: Take dated photographs (your phone’s metadata records the date and time automatically). If possible, photograph during the rain event or within minutes after. If water has already dried, photograph the staining. Write a brief log entry: date, nature of storm (light rain vs. monsoon with wind, approximate duration), and what you found. This log is the evidence your warranty claim is based on.

New Construction Buying Process in Arizona: What Ryan Does for You

Understanding why you need a buyer’s agent for new construction in Arizona — and what that agent does for you through the entire process — is worth addressing directly.

Why the Builder’s Sales Agent Cannot Represent You

The agent you meet in the model home is a licensed Arizona real estate agent employed by (or contracted to) the builder. In Arizona, this creates a dual agency situation — the agent cannot provide you with advice that conflicts with the builder’s interests. They cannot advise you to get independent inspections that might reveal problems. They cannot tell you that lot 47 has a drainage issue they know about. They cannot advise you on the leverage you have in negotiating design center upgrades or lot premiums. Their job is to sell you this builder’s homes, at the best price for the builder, with the most favorable terms for the builder.

By contrast, Ryan Moxley represents you exclusively. Arizona law requires agents to disclose agency relationships. Ryan’s agency agreement with you means his fiduciary duty is to you — to provide you with all material information, to negotiate in your favor, and to advise you even when that advice might mean choosing not to buy in a particular community.

What Ryan Provides in New Construction Representation

• Before you sign anything: Contract review for unusual provisions, warranty limitations, arbitration clauses, and builder-favorable terms that can be negotiated. Most buyers sign the builder’s standard purchase contract without any attorney or independent agent review — this is exactly when you’re most vulnerable.
• Negotiating what builders actually flex on: Builders list prices are rarely truly firm. What actually moves: lot premiums on less-desirable lots, design center upgrade allowances ($5,000–$20,000), closing cost contributions ($10,000–$25,000 when using their preferred lender), and sometimes rate buydowns. Ryan knows which builders are flexible and how to position the negotiation.
• Phase inspection coordination: Ryan schedules and attends all three phase inspections, helps interpret the inspector’s findings, and presents the findings to the builder’s construction superintendent in a way that gets action rather than dismissal.
• Design center strategy: The design center is where builders make a disproportionate margin. Certain upgrades (tile, countertops) are hard to do cost-effectively after closing; others (paint, ceiling fans, landscaping) are better done independently for far less. Ryan advises which upgrades are worth paying for at the design center and which to skip.
• Pre-closing walk-through: Ryan attends the official builder pre-closing walk-through and maintains a rigorous punch list, ensuring all items are documented in writing and scheduled for completion before or immediately after closing.
• Post-closing warranty support: Ryan remains available to help navigate warranty claims, escalate with builders when needed, and refer trusted phase inspection contractors and tradespeople throughout the warranty period.

The builder pays Ryan’s commission — you pay nothing. The builder has budgeted 2–3% of the purchase price for buyer agent commissions. If you don’t bring a buyer’s agent, the builder keeps that money — they don’t reduce the price. You’re already paying for buyer representation; bring an agent who actually represents you.

New Construction Warranty for Investors and Rental Properties

Investors purchasing new construction in Arizona for rental purposes face warranty considerations that differ meaningfully from owner-occupants. Understanding these differences before you close is important for protecting your investment.

Class 4 vs. Class 3 Property Classification

When you purchase a new construction home as an investment property (not as your primary residence), the property is classified as Class 4 under Arizona’s property classification system. Class 4 carries a 16% assessment ratio vs. 10% for owner-occupied (Class 3). On a $450,000 investment property: AV = $450,000 × 0.16 = $72,000. At a combined rate of $12/$100 AV: annual tax = $8,640. Vs. owner-occupied same home: AV = $45,000 × $12 = $5,400/year. The difference: $3,240/year in additional property taxes.

If you move into the home as your primary residence later, file for Class 3 reclassification with the Maricopa County Assessor immediately.

Warranty Claims as a Non-Occupant Owner

Many builder warranty documents define the warranty holder as the original purchaser who is an owner-occupant. If you purchased as an investor and rented the property from day one, verify that your warranty coverage is not affected. Some express warranties define coverage specifically for owner-occupants; others are property-based and transfer with the deed.

For investment properties, the 2-10 Home Buyers Warranty program’s structural coverage is property-based (not person-based) and transfers to new owners — making it particularly valuable for investors who may sell within the 10-year period. The resale value benefit of a transferable structural warranty is real: buyers will pay more for a home with an insurance-backed structural warranty remaining than one without.

Tenant Damage vs. Construction Defects

For rental properties, distinguishing between warranty-covered defects and tenant-caused damage is important and sometimes contentious. Best practices for investor-owners:

• Conduct the 11-month warranty inspection even for rental properties (have the property vacant or schedule during tenant-cooperative window).
• Document the property’s condition at move-in and move-out for each tenant with timestamped photographs. This creates a clear record separating pre-existing construction defects from tenant-caused damage.
• Submit warranty claims promptly — don’t defer to when the property is between tenants if you’re within the warranty period.
• Include a provision in tenant lease agreements requiring tenants to report water intrusion, drainage failures, and unusual sounds (possible structural movement) promptly. Delayed discovery of warrantiable defects in rental properties is common when tenants don’t report issues.
