You signed the contract. Now what? This complete guide walks through every phase of your Arizona new construction build — what happens, what to watch for, and exactly when to take action.
Build times vary significantly by builder, community, home size, market conditions, and season. The week ranges in this guide represent typical Arizona production home builds and are intended as orientation, not guarantees. Always ask your specific builder for their current build time estimate. Ask at contract signing, ask at foundation, ask at framing — build timelines shift throughout the process.
One of the most common questions from buyers who've just signed a new construction purchase agreement is simple: "What happens now?" The answer is a 10–16 month journey through 8 distinct phases, each with its own milestones, your action items, and — critically — inspection windows you need to know about before they pass.
This guide walks you through every phase. Whether you're building with D.R. Horton, Taylor Morrison, Meritage, Lennar, Pulte, or any other Phoenix metro builder, the fundamental construction sequence is the same.
Nothing visible is happening at your lot yet — but significant activity is underway behind the scenes. This is the administrative, permitting, and design phase.
Your action in Phase 0: Complete all design selections immediately. Read your contract's cancellation window deadlines and calendar every one. Begin the mortgage application process with your lender — pre-approval for a specific purchase price and estimated close date.
This phase is when visible construction begins at your lot. The foundation is arguably the most critical structural element of your home — and one of the most important inspection windows.
This window opens after PT cables, rebar, vapor barrier, and underground plumbing are in place — but BEFORE the concrete is poured. The window is brief — 24 to 48 hours. Your agent needs to know the pour date and have your inspector on standby. The inspector verifies: PT cable placement and coverage depth, rebar size and spacing, vapor barrier continuity, underground plumbing pressure test results, and grade preparation. Issues found now can be corrected easily. After the pour, they cannot be corrected without significant demolition. This is a critical inspection — don't skip it.
Post-tension slabs CANNOT be cut, drilled, or modified without structural engineering approval. If you ever want to add a pool, a drain, a wall anchor, or any penetration through the slab, you MUST hire a structural engineer to locate the PT cables first. Cutting a tensioned PT cable releases enormous force and can be catastrophic. Communicate this to every contractor who ever works on your home.
Framing is visually the most dramatic phase — your home goes from a concrete slab to a recognizable structure in a matter of weeks. Framing crews can frame a typical 2,000–2,500 sq ft Arizona production home in 1–3 weeks.
After framing, the building inspector (municipal building department) performs a framing inspection — verifying that framing meets code. Your own inspector can also perform a framing inspection during this phase to identify issues beyond minimum code compliance.
With the structure up and sheathed, the mechanical trades begin. This phase — and the inspection window at its end — is the most critical in the entire build.
This is the most important inspection in all of new construction. Everything is still visible: every stud, every pipe, every wire, every duct. Once drywall goes up, all of this is covered for the life of your home. Your inspector should check: plumbing connection types and slopes, drain vent sizing, electrical panel sizing and circuit labels, electrical ground fault protection requirements, HVAC duct sizing and sealing (critical in AZ), window rough-opening flashing (stucco water intrusion prevention), insulation placement and R-value coverage, hurricane ties and hold-downs (AZ monsoon wind resistance), fire blocking at penetrations, and any visible structural concerns in framing. Hire an ASHI- or InterNACHI-certified inspector. Attend this inspection personally. Review the report in detail and submit all items to your builder's superintendent in writing immediately.
Drywall transforms your home from an open skeleton to enclosed rooms. This phase moves quickly for the hanging but takes time for the finishing — proper drywall finishing requires multiple coats and drying time between each.
Exterior work runs concurrently with drywall. Arizona's dominant exterior finish is three-coat stucco — durable in the dry desert climate, but requiring careful attention at penetrations where water intrusion can occur during monsoon season.
Interior finishes transform the drywalled shell into a home. This phase takes the longest of any single phase and is most susceptible to scheduling bottlenecks due to the sequential nature of installation trades.
The final phase completes all mechanical systems, obtains the Certificate of Occupancy, and closes the transaction.
This is your punch list inspection — ideally with both your agent and your own independent inspector present. Verify: all finishes match your Design Center selections, all mechanical systems operate correctly (run every faucet, flush every toilet, test every outlet, run the HVAC at both heat and cool, test garage door), all punch list items from any previous inspections are resolved, no visible damage or construction defects, exterior stucco and landscaping complete. Create a written punch list, photograph every item, email the list to the builder's representative immediately with a date stamp. Do not close if material items are unresolved without a written commitment from the builder to complete within a specified timeframe.

| Delay Cause | Frequency | Typical Delay | What You Can Do |
|---|---|---|---|
| Cabinet supply chain delays | Common | 2–8 weeks | Confirm selection early; check lead time at signing |
| Window / door delays | Moderate | 2–6 weeks | Confirm availability of custom sizes at selection |
| Appliance lead times | Moderate | 2–8 weeks | Verify appliance availability before finalizing selections |
| Permit processing delays | Common in fast-growth areas | 2–6 weeks | Ask builder which jurisdiction; ask current wait time |
| Tile setter / countertop availability | Very common | 2–4 weeks | Little buyer control — understand it's a risk |
| Caliche excavation | Common in AZ | 1–3 weeks | Ask builder if caliche has been encountered in community |
| Monsoon weather (July–Sept) | Seasonal | Days to 1–2 weeks | Build buffer into your housing transition timeline |
| Buyer change orders | Avoidable | 1–6 weeks per change | Finalize all selections before signing; avoid post-contract changes |
| Lender processing delays | Moderate | 1–3 weeks | Choose lender early; respond to requests immediately |
| Subcontractor scheduling conflicts | Common in busy markets | 1–3 weeks | Little buyer control; maintain buffer in transition plan |
| Month | Climate Condition | Construction Impact | Buyer Implications |
|---|---|---|---|
| Jan–Feb | Cool, mild. Low rain. | Ideal for concrete, framing, exterior work | High-productivity window. Permits process in normal time. |
| Mar–Apr | Warm, pleasant. Possible dust storms. | Excellent. Outdoor work at peak productivity. | Best window for slab pours. Frames rise fast. |
| May | Hot. Dry. Dust storms. | Good productivity but crews start early AM shifts. | Concrete work moves to overnight/dawn. Slight slowing. |
| Jun | Very hot (105–115°F). Pre-monsoon. | Exterior work shifts to 4 AM–10 AM. Concrete limited to early morning. Some crews slow. | Anticipate some slowing of exterior trades. |
| Jul–Aug | Monsoon season. Intense afternoon/evening storms. | Concrete pours restricted — afternoon rains can damage freshly poured concrete. Framing and roofing work interrupted by storms. Framing crews still productive in mornings. | Higher delay risk for foundation and exterior work. Build extra buffer. |
| Sep | Monsoon tapering. Still hot. | Returning to normal productivity. Exterior work improving. | Recovery phase — work that was delayed in July/August catches up. |
| Oct–Nov | Cooling, beautiful. Best weather of year. | Peak productivity window. All trades fully productive. | Best time of year for closings — nice weather, smooth final phases. |
| Dec | Cool. Holidays reduce crew availability. | Holiday slowdowns — many subcontractors take extended breaks. Permit offices may have reduced hours. | December builds may slow. Anticipate holiday gaps. |
The most stressful part of new construction for many buyers is the housing gap — what happens between when you need to vacate your current home and when your new construction home is ready. Managing this transition requires careful planning starting at contract signing.
Builder construction timelines are estimates. They can slip 2–6 months or more. The safest approach is to not close on the sale of your current home (or end your lease) until you have written confirmation from the builder of the Certificate of Occupancy date — ideally within 30 days.
Your builder relationship doesn't end at closing. Most builder warranty programs include:
The industry-standard practice is the 11-month inspection — hire an ASHI/InterNACHI inspector at month 10–11 to systematically document any issues before the 1-year workmanship warranty expires. Common finds: drywall nail pops, settling cracks in drywall, grout cracking in tile, door/window alignment issues, HVAC calibration needs, minor plumbing fixture leaks. All of these are warranty-covered items the builder should repair at their cost.
Set a calendar reminder NOW for 10 months from your anticipated closing date.

Many new construction buyers don't realize how actively their buyer's agent can — and should — be involved during the build process. Here's what an experienced new construction buyer's agent does during each phase:
| Build Phase | What Your Agent Does | Why It Matters |
|---|---|---|
| Contract & Pre-Construction | Reviews contract, identifies red flags, tracks deadlines, sets up milestone calendar | Protects earnest money; ensures you know your rights and obligations from Day 1 |
| Foundation Phase | Coordinates pre-pour inspector, attends or follows up on inspection, documents results in writing to builder | Ensures structural issues are caught before they're concrete — literally |
| Framing Phase | Site visits, photographs framing, identifies any structural concerns | Early identification of framing issues before interior systems are installed |
| Rough-In Mechanical | Coordinates pre-drywall inspection, attends with inspector, creates documented punch list, submits to builder superintendent in writing same day | Most important inspection window — agent ensures it happens and is properly documented |
| Drywall & Finishes | Regular check-ins, verifies finish selections match contract, photographs any discrepancies | Catches selection substitutions or contractor errors before they're sealed up |
| Pre-Close Walk-Through | Attends walk-through, creates comprehensive written punch list, photographs every item, emails immediately to builder | Ensures punch list is documented before closing, builder commitment is written |
| Closing | Reviews HUD/CD for accuracy, attends closing, confirms keys received same day (AZ dry funding) | Final advocacy — ensures transaction closes correctly with no surprises |
| Post-Closing (11-Month) | Sends reminder for 11-month warranty inspection, can recommend inspectors | Ensures buyer captures warranty value before 1-year workmanship window closes |
Different production builders in the Phoenix metro have different reputations for build speed and consistency. Here's a general guide based on market knowledge — always ask your specific builder's sales representative for current build time estimates at your specific community:
| Builder | Typical AZ Build Time | Reputation on Timelines | Notes |
|---|---|---|---|
| D.R. Horton | 9–14 months | Generally consistent | High-volume production builder; standardized systems support consistency |
| Lennar | 10–15 months | Moderate | Can have supply chain delays on included appliance packages; "Everything's Included" model |
| Taylor Morrison | 10–16 months | Good | More design flexibility = slightly more delay risk; good communication reputation |
| Meritage | 10–14 months | Good | Energy-efficiency focus; spray foam roof deck insulation standard; generally on-time reputation |
| Pulte | 10–15 months | Moderate-Good | PulteGroup brand portfolio (also Centex, Del Webb, DiVosta); quality varies by community |
| Toll Brothers | 12–20 months | More variability | Higher-end semi-custom; more buyer customization = more delay potential |
| KB Home | 9–13 months | Generally consistent | High production volume; highly buyer-customizable within defined package options |
Timing the sale of your existing home is one of the most consequential decisions in a new construction purchase. Get it wrong and you either: (A) sell too early and need temporary housing; or (B) sell too late and carry two mortgages simultaneously. Neither is comfortable. Here's a framework:
This approach eliminates the risk of carrying two mortgages but creates a housing gap. Best practices:
If you can qualify for both mortgages simultaneously, or have sufficient cash/investments for the new home down payment, you can complete the new home purchase and then sell after moving in. Benefits: no housing gap, no rush to sell the current home. Risks: carrying two mortgages for potentially 30–90 days; current home may be vacant during new construction build, increasing insurance costs.
Some builders allow a contingent purchase tied to the sale of your existing home. This protects you but makes your offer less competitive in builder communities where multiple buyers want the same lot. Builders prefer non-contingent buyers. If contingency is necessary, expect the builder to require a shorter contingency period than you'd get in a resale transaction.
After working through many new construction purchases with Phoenix metro buyers, here are the milestones buyers most commonly miss or misunderstand:
Many builders give you 2–4 weeks from contract signing to finalize all design selections. This feels like a long time until you're actually in the Design Center looking at 47 cabinet finish options, 23 countertop choices, and 15 flooring colors — while a design consultant waits and a manager keeps checking in. Miss this deadline, and the builder makes standard selections for you. Take the deadline seriously and prepare in advance: tour model homes, take photos, look at design inspiration images. Come to the Design Center prepared.
Understand when your earnest money transitions from "potentially refundable" to "at risk." Many buyers know there's a review window but don't fully process that once it closes, their earnest money is gone if they cancel. Some builder contracts release portions of earnest money at different milestones — upon contract, upon start of construction, upon permit. Know your contract's specific structure.
If you're using a builder's lender or any lender with an extended rate lock, know the expiration date and what happens when it expires: do you pay for a lock extension? Does your rate float to market? What if the build runs significantly late? These are lender-specific questions — get answers in writing before closing.
Most builders specify a deadline for submitting punch list items in writing — both in the contract and in the walk-through process. If you discover items after the walk-through deadline, you may have fewer remedies than if you'd documented them during the formal walk-through. Don't rush through the final walk-through. Bring your agent. Bring an inspector if allowed. Take 2–3 hours to be thorough.
Set a reminder for this now. Month 10–11 from your closing date. The 1-year workmanship warranty window closes at month 12. The 11-month inspection gives you time to submit warranty claims and have them addressed before the window expires. This inspection typically costs $300–$500 and can return thousands in covered repairs.

A new construction build taking 10–14 months creates unique mortgage financing challenges that resale buyers never face. Understanding these challenges and planning for them can prevent closing delays and financial surprises.
Standard 30 and 60-day rate locks don't work for new construction. You need one of these options:
A long build timeline creates income verification challenges for self-employed buyers. If you close in October 2027 on a home contracted in October 2026, your lender will need to verify income based on 2025 and/or 2026 tax returns — potentially filed after the contract was signed. Ensure your income documentation strategy accounts for the timeline.
Between contract signing and closing (10–14 months), avoid: opening new credit accounts, making large purchases on credit, changing jobs, or taking on new debt. Your credit profile at closing must support the loan you were pre-approved for at contract signing. Lenders typically pull a new credit report immediately before closing.
Beyond the standard inspection checklist items, Arizona's unique climate creates specific quality indicators worth evaluating in new construction:
Arizona homes experience extreme thermal cycling — roofs expand and contract significantly between summer highs (150°F on the surface) and winter lows. Quality indicators: weight of concrete or clay tile (heavier = more durable), underlayment specification (Class A fire-rated, at minimum 30-lb felt or synthetic equivalent), proper ventilation design, attic radiant barrier (standard in most AZ new construction, verify).
Windows in Arizona face intense solar heat gain. Look for: Low-E glass coating (standard in most AZ new construction; verify the SHGC — Solar Heat Gain Coefficient — lower is better for AZ), proper argon or krypton gas fill between panes, aluminum-clad wood or vinyl frames (not standard aluminum, which conducts heat), proper caulking and flashing at rough openings (water intrusion during monsoon).
If a future pool is in your plans, ask about post-tension slab layout BEFORE the pour. The builder's engineer may be able to route PT cables to allow for a future pool bond beam and equipment location without cutting existing cables. Once the slab is poured, your pool location options are constrained by where the PT cables are.
In a hot, unconditioned attic space (which can reach 150–160°F in Arizona summers), leaky ductwork is enormously expensive. A poorly-sealed duct system can waste 25–40% of your cooling energy, adding hundreds of dollars per month to utility bills and prematurely stressing your HVAC equipment. Ask your pre-drywall inspector specifically about duct sealing quality and mastic or metal tape at all connections.
For many buyers, the choice between new construction and resale is as consequential as the choice of neighborhood. Here's a direct comparison to help you evaluate which path is right for you in the 2026 Phoenix market:
| Factor | New Construction | Resale |
|---|---|---|
| Timeline to move in | 10–16 months | 30–60 days from contract |
| Condition | New — no maintenance issues, warranties | Variable — inspection period critical |
| Customization | Design center selections (within builder options) | None — buy what exists |
| Negotiating leverage | Limited — builders hold prices; negotiate incentives | More flexible — seller motivated by individual circumstances |
| Inspection | Pre-pour, pre-drywall, final — proactive | Single 10-day inspection period (BINSR) |
| Earnest money risk | Higher — 3–10% at risk after review window | Lower — typically 1%, BINSR protection |
| HOA | Developer-controlled initially; newer rules | Established HOA — more history and community governance |
| Energy efficiency | Modern standards — lower utility bills | Variable — older homes may have less insulation, less efficient HVAC |
| Landscaping | Minimal — front only typically; back yard is yours | Established landscaping (pro or con depending on preferences) |
| CFD assessments | Common in new developments | May exist in established communities too; verify |
| Price relative to market | Builder pricing is non-negotiable on base price; incentives flexible | Market-priced; full negotiation possible |
