North Phoenix's premier new-construction master-planned community — multiple builders, resort amenities, A-rated DVUSD schools, and unbeatable freeway access via I-17 and Loop 303.
Community Overview
Union Park at Norterra represents one of North Phoenix's most ambitious and well-executed master-planned communities of the modern era. Located at the intersection of Happy Valley Road and Interstate 17 — one of the valley's most strategically valuable freeway interchanges — Union Park began delivering homes in 2018 and continues to grow through 2026 and beyond, with planned buildout exceeding 3,000 homes across multiple villages and builder collections.
The community is developed within the larger Norterra master-planned district, which encompasses retail, commercial, medical, and residential uses across thousands of acres in this rapidly expanding northwest Phoenix corridor. Union Park is the residential crown jewel of Norterra — a purpose-built neighborhood with its own identity, amenity infrastructure, and community governance layered within the Norterra master association.
What distinguishes Union Park from other North Phoenix developments is the combination of multiple nationally recognized builders under a single master association umbrella, a flagship amenity center called The HUB that rivals luxury resort pools, and a school system — Deer Valley Unified School District — that consistently ranks among Arizona's highest-performing districts. Whether you are a first-time buyer taking advantage of Taylor Morrison's entry-level collections, a move-up family drawn to Toll Brothers' luxury finishes, or an executive relocating for the TSMC semiconductor corridor 20–25 minutes away, Union Park offers a product for every budget tier within one cohesive, amenity-rich community.
The community's active building status through 2026 means buyers can still purchase from some builders pre-construction — selecting lot, elevation, floor plan, and structural options — while resale opportunities in earlier-delivered phases are now appearing as original owners capture appreciation and move on.

Builders & Home Collections
Union Park at Norterra distinguishes itself by assembling four nationally recognized homebuilders under a single master-planned umbrella, ensuring that buyers at every price point can find a home that fits their needs — with access to the same community amenities, schools, and location advantages regardless of which builder they choose.
Taylor Morrison is the highest-volume builder at Union Park and the primary driver of the community's diversity of choice. Their collections in Union Park range from the more attainable Waterford and Bradford series — efficient 2-story floor plans in the 1,800–2,600 sq ft range — to their larger Parker and Walton series approaching 3,500 sq ft. Taylor Morrison is known for strong standard finishes, a well-structured design center process, and reliable construction timelines. The builder's Union Park homes feature open-concept great rooms, 2-car and 3-car garages, covered rear patios, and flexible floor plans accommodating home offices and multi-gen living arrangements.
Toll Brothers brings its nationally recognized luxury brand to Union Park, delivering the community's premium product. Their Union Park collection features single-story and two-story luxury homes in the 2,800–4,500 sq ft range, with expansive primary suites, gourmet kitchens, dramatic great rooms with 12-foot ceilings, and extensive personalization options through Toll Brothers' Design Studio. Toll's Union Park lots frequently include premium positions — larger lots, cul-de-sac placements, or mountain-view lots — that justify the premium over the community's other builders. Buyers choose Toll for the brand's proven resale reputation, quality of standard finishes, and the elevated buying experience their design centers provide.
Formerly known as Landsea Homes in the Phoenix market, Brightland Homes offers a strong mid-market position at Union Park, delivering well-designed 2-story and single-story floor plans with an emphasis on energy efficiency and modern aesthetics. Brightland's Union Park homes range from approximately 2,000 to 3,200 sq ft and are popular with move-up buyers seeking more than entry-level finishes without reaching Toll Brothers pricing. The builder has invested significantly in its energy-efficient construction envelope — including spray foam insulation, high-efficiency HVAC systems, and Low-E windows — which translates to meaningfully lower utility costs in Phoenix's hot climate. This is a particularly valuable selling point for budget-conscious buyers who want to model true cost of ownership.
Mattamy Homes, North America's largest privately held homebuilder, brings its well-regarded "thoughtfully designed" philosophy to Union Park. Mattamy's floor plans are notable for their practical ingenuity — features like their Anywhere Room (a flex space that adapts from office to playroom to guest suite), well-proportioned secondary bedrooms, and storage-focused design. Mattamy's Union Park collection spans approximately 2,100 to 3,400 sq ft and occupies a competitive mid-market position. The Canadian-origin builder is particularly strong with multi-generational living configurations and first-time move-up buyers who have outgrown their starter homes. Mattamy's build quality and customer satisfaction scores consistently rank well in J.D. Power homebuilder surveys.
Every builder at Union Park employs on-site sales agents whose legal duty runs to the builder — not to you. These agents are skilled at selling their community's homes, but they cannot represent your interests in price negotiations, contract terms, lot selection, or upgrade value analysis.
An independent buyer's agent like Ryan Moxley represents only you, at no additional cost (the builder pays the buyer's agent commission). Ryan has negotiated closing cost credits, free upgrades, lot premium waivers, and extended rate locks for buyers at new construction communities across the Phoenix metro. He can also arrange a critical pre-drywall inspection — the most important inspection in any new build — and review all HOA and CFD documents before you sign.

Community Amenities
At the heart of Union Park at Norterra is The HUB — a resort-style amenity center that sets the community apart from other North Phoenix master-planned developments. Rather than a small HOA clubhouse with a modest pool, The HUB is a full-scale recreation destination that rivals the amenity packages at premier resort-residential communities found in higher price brackets. Homeowners at Union Park have The HUB included in their HOA dues, providing daily access to facilities that would cost thousands per year in membership fees elsewhere.
Large zero-entry resort-style pool with shade structures, lounge chairs, and covered seating areas
Full lazy river circuit — a rare feature in HOA communities, normally found only at resort properties
Interactive splash pad for young children — ground-level water jets, tipping buckets, and spray features
Fully equipped fitness center with cardio machines, free weights, and functional training equipment
Multiple dedicated pickleball courts — one of the fastest-growing sports in the Phoenix metro
Full-size basketball courts for pickup games, leagues, and youth programs
Sand volleyball courts for leagues and casual play — popular for community social events
Miles of paved walking and biking paths connecting Union Park villages and Norterra's preserve areas
Dedicated off-leash dog parks with separate areas for large and small breeds, agility features, and water stations
Multiple neighborhood parks with covered ramadas, BBQ grills, playgrounds, and green space throughout the community
The HUB clubhouse with event spaces, gathering rooms, and community organization meeting facilities
Norterra Marketplace with Sprouts, HomeGoods, Target, restaurants, and services — walkable or 1-minute drive
Union Park residents benefit not only from The HUB but from the entire Norterra master development surrounding them. Norterra Shopping Center at Happy Valley Rd and I-17 puts a full retail ecosystem literally at the neighborhood's doorstep — Sprouts Farmers Market, HomeGoods, multiple restaurant concepts, fitness studios, urgent care, and specialty retailers. This walkable commercial access is what separates Norterra from pure-residential master communities where residents must drive 10+ minutes for basic errands.
Nearby Desert Ridge Marketplace (10 minutes east) adds another major retail, dining, and entertainment hub — including AMC Theatres, Dave & Buster's, Whole Foods, The Yard sports bar complex, and dozens of restaurants — further expanding the lifestyle amenities available to Union Park residents without a significant commute.
Education
Deer Valley Unified School District (DVUSD) serves Union Park at Norterra and consistently ranks among the top school districts in the Phoenix metro area. DVUSD encompasses 43 schools serving approximately 30,000 students across northern Phoenix, earning an overall "A" district rating from the Arizona Department of Education (ADE). For families with school-age children, this is one of the strongest arguments for choosing Union Park over comparable communities in other North Phoenix districts.
Norterra Canyon is the crown jewel of Union Park's school story — a K-8 campus located within walking distance of many Union Park homes. The school combines elementary and middle school under one roof, eliminating the transition stress common in separately sited schools. Academic programming emphasizes STEM integration, with science labs and technology resources that exceed what many district middle schools provide. The school's proximity means children can walk or bike to school safely, and after-school pickup is integrated with the surrounding neighborhood's pedestrian infrastructure. ADE has rated Norterra Canyon an A school in multiple consecutive years, reflecting strong academic outcomes and parent satisfaction. The K-8 configuration means Union Park families maintain a consistent school community from kindergarten through 8th grade — a significant lifestyle advantage for active families.
Named for Arizona's own Supreme Court Justice, Sandra Day O'Connor High School is consistently one of the most celebrated high schools in the Deer Valley Unified School District and the broader Phoenix metro. The school offers an extensive Advanced Placement (AP) program with 30+ AP courses available, allowing motivated students to earn college credit while still in high school. The school's College and Career Readiness programs include dual enrollment opportunities with local community colleges. Athletics programs are competitive at the state level, with multiple state championship teams in recent years across football, volleyball, swimming, and cross country. SDOHS's performing arts program — including choir, band, orchestra, and theater — is renowned within DVUSD. The school's graduation rate exceeds 97%, and the percentage of graduates pursuing 4-year college degrees consistently ranks among Arizona's highest for public high schools.
Barry Goldwater High School serves portions of Union Park (depending on specific street address) and is itself a strong performing institution within DVUSD. The school offers robust CTE (Career and Technical Education) programs particularly strong in construction trades, automotive technology, and digital media — programs that align with the hands-on technical workforce needs of the Phoenix metro's growing semiconductor and advanced manufacturing industries. Barry Goldwater has produced numerous college athletes and maintains an active JROTC program popular with students from military families in the area. If you are purchasing in Union Park and your high schooler's school assignment matters, confirm the specific boundary for your lot's address with DVUSD directly, as boundaries can be updated and some Union Park sections may qualify for school choice enrollment at SDOHS even if Goldwater is the boundary school.
School Comparison Table
| School | Grades | District | ADE Rating | Enrollment | Distance | Notable Programs |
|---|---|---|---|---|---|---|
| Norterra Canyon School | K–8 | DVUSD | A | ~600 | Walkable | STEM, Technology Integration |

School assignments depend on home address. Always verify your lot's boundary assignment at dvusd.org or by contacting the district enrollment office. Open enrollment and AZ Empowerment Scholarship Account (ESA) options may expand choices further.
Critical Buyer Information
Union Park at Norterra carries active Community Facilities District (CFD) assessments that add $1,500 to $3,000+ per year to your annual property tax obligation. This amount is separate from and in addition to your regular Maricopa County property taxes and is not included in the property tax figure that appears in MLS listings. Many buyers are surprised to discover this additional cost after contract execution — do your homework before writing an offer.
When comparing Union Park to other communities, always calculate the true annual carrying cost: Base Property Tax + CFD Assessment + HOA Fees (combined Norterra master + Union Park sub). For a mid-tier home at $650,000, this might look like: ~$8,450 base tax + ~$2,200 CFD + ~$2,760 HOA = ~$13,410/year in annual overhead costs, or roughly $1,118/month in addition to your mortgage payment.
Some portions of the broader Norterra development may also carry Special Improvement District (SID) assessments in addition to or instead of CFD assessments. SIDs operate similarly — bonds issued under ARS Title 48 for infrastructure, repaid by property owners over time. Your title commitment will identify any SIDs applicable to a specific parcel. Always review Schedule B exceptions carefully before closing.
Location & Access
Union Park at Norterra sits at one of North Phoenix's most strategically valuable freeway intersections: Happy Valley Road and Interstate 17 (Black Canyon Freeway), with Loop 303 (Veterans Highway) just minutes west. This positioning provides virtually unimpeded access to every major employment center, airport, and destination in the greater Phoenix metro — making Union Park a genuinely all-directions commuter community.
Union Park's location at Happy Valley Rd and I-17 is not incidental — it is one of the primary reasons this land was selected for master-planned development. Interstate 17 is the primary north-south arterial connecting North Phoenix to downtown, the airport, and the south valley. The nearby Loop 303 interchange (completed 2022, fully operational) provides direct west valley access without ever touching I-17's congestion. For buyers commuting to the TSMC/Intel semiconductor corridor, the tech campuses along Loop 101 in North Phoenix are a straight 20-minute shot east via Happy Valley Rd connecting to 101.
Unlike Desert Ridge communities (which require surface street navigation before reaching a freeway), Union Park homes can be on I-17 within 2–4 minutes of leaving their driveway — a significant quality-of-life advantage for daily commuters.
The Norterra Shopping Center at I-17 and Happy Valley Rd is essentially Union Park's front yard — a well-curated outdoor retail center anchored by Sprouts Farmers Market, HomeGoods, PetSmart, multiple quick-serve and sit-down restaurant chains, urgent care, veterinary clinics, and specialty retailers. This retail proximity eliminates the "isolated suburb" dynamic that can diminish quality of life in purely residential master communities developed without adjacent commercial infrastructure.
Additional commercial nodes at Norterra's expanded commercial segments continue to add medical offices, fitness studios, and restaurant options — making the area increasingly self-contained for day-to-day living needs.
Economic Catalyst
Taiwan Semiconductor Manufacturing Company (TSMC) is executing the largest foreign direct investment in US history at its Fab 21 campus in North Phoenix's Deer Valley corridor. The $65 billion facility — located approximately 20–25 minutes from Union Park via I-17 and Loop 101 — is producing 4nm and 3nm semiconductor chips in Phase 1 operations, with Phase 2 (2nm technology) under active construction and Phase 3 under consideration.
TSMC's 10,000+ direct employees and 50,000+ indirect jobs in the supply chain, construction, and services ecosystem are overwhelmingly concentrated in the North Phoenix corridor within a 30-minute radius of Fab 21. The semiconductor workforce — engineers, technicians, process specialists, equipment operators, and support professionals — earns salaries averaging $90,000–$180,000+, creating a highly qualified, well-compensated buyer pool searching for housing in exactly the North Phoenix communities where Union Park competes.
For Union Park specifically, the TSMC effect manifests in both demand and pricing: engineers and management professionals — many relocating from Taiwan, Japan, California, and Texas — have been active buyers in the $600K–$1.2M price range that Union Park's Toll Brothers and upper-tier Brightland/Mattamy collections occupy. The TSMC workforce cohort values the same attributes Union Park delivers: top-rated schools (DVUSD's STEM programs align with tech worker family priorities), freeway access, resort-level amenities, and homes that accommodate multi-generational living (a cultural priority for many Taiwanese and East Asian buyers).
Intel's $20 billion Fab 52 and Fab 62 expansion in Chandler employs 12,000+ at its Arizona campus. While Chandler is ~45–55 minutes from Union Park, many Intel employees live in the broader North Phoenix corridor due to school quality and lifestyle preferences, accepting a longer commute for DVUSD schools and resort-level HOA amenities. The semiconductor industry concentration across multiple campuses makes North Phoenix the single most in-demand corridor for tech-sector homebuyers in Arizona.
Buyer's Guide
Buying new construction at Union Park differs significantly from buying a resale home, and buyers who approach it without guidance often leave money on the table or agree to contract terms less favorable than what a represented buyer could achieve.
Step 1: Builder's Contract vs. Arizona AAR Contract. Each builder at Union Park uses their own proprietary purchase agreement — not the standard Arizona Association of REALTORS® Residential Purchase Contract. Builder contracts are written by the builder's attorneys, favor the builder in virtually every clause, and contain provisions that would not appear in a standard resale transaction. Key differences: earnest money is typically non-refundable after a short inspection window; the builder retains rights to change materials and specifications as long as comparable alternatives are used; closing dates can be extended at builder's discretion without buyer compensation.
Step 2: Design Center Selections. After lot and plan selection, most builders schedule a Design Center appointment where buyers choose flooring, countertops, cabinets, fixtures, and structural options. Design Center visits typically last 3–8 hours. The upgrade cost can range from $15,000 to $150,000+ depending on how extensively you upgrade. Understanding which upgrades add resale value vs. which are emotional purchases is where a knowledgeable agent provides enormous value.
Step 3: Inspections. Arizona's BINSR (Buyer's Inspection Notice and Seller's Response) process applies even to new construction. The most critical inspection for a new build is the pre-drywall (or "frame") inspection — conducted after framing, electrical, plumbing, and HVAC rough-in but before the walls are closed. This inspection allows an independent inspector to verify structural framing, verify plumbing and electrical rough-in, confirm HVAC duct routing, and identify any items needing correction while they are still accessible. Once drywall is installed, many defects are hidden for years.
All builders at Union Park must comply with Arizona's Right to Repair statute (ARS §12-1361 through §12-1366), which establishes minimum warranty periods and defines the dispute resolution process for construction defects:
Before filing a lawsuit for construction defects, homeowners must follow ARS §12-1363's notice and opportunity-to-repair process — giving the builder written notice and a 60-day window to inspect and offer a remedy. Understand this process before purchasing and retain all punch-list documentation from your walkthroughs.
Most new construction homes in the Phoenix metro — including at Union Park — use post-tensioned concrete slabs. Post-tension slabs use high-strength steel cables tensioned within the concrete to resist soil movement and cracking. They are superior to standard slabs in AZ's expansive clay soils, but they carry one absolute rule: NEVER cut, drill, or penetrate a post-tension slab without an engineer's approval and precise cable mapping. Cutting a cable causes catastrophic failure and repair costs of $10,000–$30,000+. This applies to future pool installation, underground plumbing modifications, and any utility trenching within the slab footprint.
The 2026 conforming loan limit for Maricopa County is $806,500. Entry-tier and mid-tier Union Park homes fall within conventional conforming limits. Upper-tier Toll Brothers homes above $806,500 require jumbo financing — which has its own underwriting standards (typically 20% down, 720+ credit score, reserves of 6–12 months PITI). Fannie/Freddie-backed conventional loans at sub-$806K price points typically require only 3–5% down for qualified buyers, and the ADOH HOME Plus program offers 3–5% down payment assistance for buyers meeting income eligibility ($122,100 household income limit, 640+ credit score).
HOA & Governance
Union Park at Norterra operates under a layered HOA structure that buyers must fully understand before purchasing. Rather than a single association, most Union Park homes are subject to two or three separate HOA entities, each with its own CC&Rs, fee schedule, and governance structure. All must be reviewed as part of your due diligence process under Arizona's HOA disclosure requirements (ARS §33-1806).
The Norterra Master Association governs the overarching Norterra district, covering shared infrastructure, aesthetics standards for the entire development, and maintenance of common areas within the master footprint. This association typically runs $60–$120/month and covers master-level landscaping, common area maintenance, and enforcement of the Norterra design guidelines (which govern exterior colors, landscaping requirements, fence types, and holiday decorations visible from the street).
The Union Park Community Association governs the Union Park residential component specifically, covering The HUB amenity center, Union Park-specific parks, trails, and common areas. This association typically runs $100–$150/month and provides the resort amenity access that distinguishes Union Park from surrounding Norterra non-residential communities.
Some individual villages within Union Park — particularly Toll Brothers sections with additional amenities or unique shared features — may carry a third sub-HOA with fees typically ranging $40–$80/month. This layer covers village-specific landscaping, entry features, and any unique amenities within that specific builder's section. Confirm all applicable associations for the specific lot address during the contract review period.
Arizona law requires sellers to provide buyers with the HOA disclosure package (CC&Rs, bylaws, budget, financial statements, meeting minutes, rules, and pending assessments) within 5 days of contract execution. Buyers have 5 days from receipt to cancel based on HOA documents. This is a critical due diligence window — use it to review CFD obligations, HOA reserve fund adequacy, pending litigation or special assessments, and any rules that affect your intended use of the property (STR restrictions, parking rules, pet policies, fencing requirements).
Arizona law (ARS §9-500.39) preempts local government bans on short-term rentals (Airbnb, VRBO, etc.) — but HOA CC&Rs CAN legally restrict or prohibit STRs within a community. Union Park's HOA documents restrict STR activity in most sections, requiring minimum rental periods of 30 days or longer. Buyers who intend to rent their home short-term must review the specific CC&Rs for their village before purchasing — the restriction is legally enforceable by the HOA.
Arizona HOAs have lien rights on your property for unpaid assessments and the right to foreclose that lien under ARS §33-1807. HOA dues, special assessments, and fines that go unpaid can result in foreclosure proceedings independent of your mortgage lender. Ensure all HOA dues are current at closing (confirmed on the HOA estoppel certificate) and budget appropriately for combined monthly HOA obligations plus potential special assessments for major capital projects.
