RE — Rural/Estate Residence

The lowest-density residential district, designed for rural and estate-style living on large lots. Provides generous lot sizes and setbacks to maintain a rural character on the urban fringe.

Typical uses: Single-family dwelling, Horses/livestock (with restrictions), Home occupation, Agricultural uses (limited), Guest house

Max height: 30 ft. Min lot size: 35,000 sq ft. Setbacks: Front: 40 ft, Side: 25 ft, Rear: 40 ft. Lot coverage: 25%.

Developer notes: Found in North Phoenix and outer-fringe areas like Laveen and Desert Ridge. Rezoning from RE to higher-density residential is a common entitlement play in areas where the General Plan supports growth, but neighborhood opposition can be intense.

R1-6 — Single Family Residence (6,000 sq ft)

The most common single-family zoning district in Phoenix. Designed for traditional suburban-density single-family neighborhoods on 6,000 sq ft minimum lots. Found throughout the city.

Typical uses: Single-family dwelling, Accessory dwelling unit (ADU), Home occupation, Group home (up to 5 residents)

Max height: 30 ft. FAR: 0.50:1 (effective). Min lot size: 6,000 sq ft. Setbacks: Front: 20 ft, Side: 5 ft, Rear: 20 ft. Lot coverage: 40%.

Developer notes: The dominant residential zoning across Phoenix. Infill lot splits and new subdivisions in R1-6 are bread-and-butter for residential builders. Arizona SB 1162 (2023) legalized ADUs statewide, adding small-scale infill potential to every R1-6 lot.

R-2 — Multifamily Residence (Low Density)

Low-density multifamily district that bridges the gap between single-family and apartment zoning. Permits duplexes, townhouses, and small apartment buildings.

Typical uses: Duplexes, Townhouses, Small apartment buildings, Single-family dwellings, Group homes

Max height: 30 ft. Min lot size: 6,000 sq ft (duplex). Setbacks: Front: 20 ft, Side: 5 ft, Rear: 20 ft. Lot coverage: 45%. Parking: 1.5 spaces per unit (1 BR); 2 spaces per unit (2+ BR).

Developer notes: Good for small-scale multifamily infill — duplexes and townhomes. The 30 ft height cap limits buildings to 2 stories. Commonly found in transitional areas between single-family neighborhoods and commercial corridors.

R-3 — Multifamily Residence (Medium Density)

Medium-density multifamily district permitting apartment complexes at moderate density. One of the most commonly sought districts for garden-style apartment development in Phoenix.

Typical uses: Apartments, Condominiums, Townhouses, Duplexes, Assisted living facilities

Max height: 40 ft. FAR: 1.0:1. Min lot size: 6,000 sq ft. Setbacks: Front: 20 ft, Side: 10 ft (adjacent to SF), Rear: 20 ft. Lot coverage: 50%. Parking: 1.5 spaces per unit (1 BR); 2 spaces per unit (2+ BR).

Developer notes: The workhorse multifamily district in Phoenix. 40 ft height allows 3-story wood-frame construction — the most cost-efficient apartment building type. R-3 parcels along major arterials and near light rail are prime targets for garden-style apartment developers.

R-4 — Multifamily Residence (Medium-High Density)

Higher-density multifamily district for apartment and condominium projects near major corridors and employment centers. Allows taller buildings and greater site coverage than R-3.

Typical uses: Apartments, Condominiums, Townhouses, Assisted living, Group residential

Max height: 48 ft. FAR: 1.5:1. Min lot size: 6,000 sq ft. Setbacks: Front: 20 ft, Side: 10–15 ft, Rear: 20 ft. Lot coverage: 55%. Parking: 1.5 spaces per unit (1 BR); 2 spaces per unit (2+ BR).

Developer notes: 48 ft height accommodates 4-story construction. The higher FAR over R-3 yields substantially more leasable area per land dollar. Key for developers targeting mid-rise multifamily along Central Avenue, Camelback Corridor, and Midtown.

R-5 — Multifamily Residence (High Density)

The highest-density residential district in Phoenix, permitting apartment towers and high-density condominium projects. Found in downtown-adjacent areas and major activity centers.

Typical uses: High-density apartments, Condominium towers, Group residential, Mixed-use (with use permit)

Max height: 56 ft (up to 250 ft with use permit). FAR: 2.0:1. Min lot size: 10,000 sq ft. Setbacks: Front: 20 ft, Side: 15 ft, Rear: 20 ft. Lot coverage: 60%. Parking: 1.5 spaces per unit (1 BR); 2 spaces per unit (2+ BR).

Developer notes: The most intensive residential zone. With a use permit, R-5 can achieve up to 250 ft and 43 units/acre, making it the go-to district for high-rise residential towers in downtown, Midtown, and the Camelback Corridor. Height beyond 56 ft requires use permit approval through the Planning Commission and City Council.

C-1 — Neighborhood Retail

Designed for small-scale, neighborhood-serving retail and service uses. Intended to be compatible with adjacent residential areas through lower intensity and restricted hours.

Typical uses: Neighborhood retail, Personal services, Restaurants (limited), Professional offices, Day care centers

Max height: 30 ft. Setbacks: Front: 20 ft (0 ft with pedestrian-oriented design), Side: 10 ft (adjacent to residential). Lot coverage: 50%. Parking: Per use — typically 1 per 250 sq ft retail.

Developer notes: Limited commercial district best suited for small neighborhood centers. The 30 ft height cap and restricted use list make this less attractive for larger commercial projects. Often a stepping stone for developers seeking C-2 entitlements in transitional areas.

C-2 — Intermediate Commercial

The most common and versatile commercial zoning district in Phoenix. Permits a wide range of retail, office, service, and entertainment uses at moderate intensity along major arterials and commercial nodes.

Typical uses: Retail sales, Restaurants, Offices, Hotels/motels, Entertainment venues, Personal services, Auto services (limited)

Max height: 40 ft. FAR: 1.0:1. Setbacks: Front: 0 ft (urban) to 20 ft, Side: 10 ft (adjacent to residential). Lot coverage: 60%. Parking: Per use — typically 1 per 250 sq ft retail, 1 per 300 sq ft office.

Developer notes: The backbone of Phoenix commercial zoning. C-2 parcels along major arterials (Camelback, Indian School, Thomas, McDowell) are the most actively traded commercial sites. With a use permit, mixed-use residential is achievable in C-2, making these parcels dual-purpose plays for developers who can entitle residential density.

C-3 — General Commercial

The most permissive general commercial district. Allows virtually all commercial uses including those excluded from C-2 such as auto sales, heavy commercial services, and outdoor storage.

Typical uses: All C-2 uses, Auto sales and repair, Building materials, Outdoor storage, Heavy commercial services, Wholesale trade

Max height: 56 ft. FAR: 1.5:1. Setbacks: Front: 0 ft (urban) to 20 ft, Side: 10 ft (adjacent to residential). Lot coverage: 65%. Parking: Per use — typically 1 per 250 sq ft retail.

Developer notes: The widest range of commercial uses in Phoenix. C-3 parcels are found along major highways and in commercial/industrial transition areas. The 56 ft height and higher FAR make C-3 sites attractive for larger-format commercial or mixed-use projects. Often found along I-17 and I-10 frontage.

CP — Commerce Park

Designed for office, research, and light industrial campus-style developments. Emphasizes high-quality design standards with landscaping buffers and limited outdoor storage.

Typical uses: Office parks, Research and development, Light manufacturing, Data centers, Medical facilities, Flex space

Max height: 56 ft. FAR: 0.60:1. Min lot size: 1 acre (typical for campus sites). Setbacks: Front: 30 ft, Side: 20 ft, Rear: 20 ft. Lot coverage: 50%. Parking: 1 per 300 sq ft office.

Developer notes: The go-to district for corporate campus and flex developments in areas like Desert Ridge, Deer Valley, and the Loop 101 corridor. The design standards requirement adds cost but yields higher-quality tenants and rents. Data center demand is driving significant interest in CP-zoned parcels.

A-1 — Light Industrial

Permits light manufacturing, warehousing, distribution, and industrial services that can operate without significant external impacts on surrounding areas.

Typical uses: Warehousing and distribution, Light manufacturing, Flex industrial, Wholesale trade, Equipment rental, Self-storage

Max height: 56 ft. FAR: 1.0:1. Min lot size: 10,000 sq ft. Setbacks: Front: 20 ft, Side: 0 ft (10 ft adjacent to residential), Rear: 0 ft. Lot coverage: 70%. Parking: 1 per 1,000–2,000 sq ft (varies by use).

Developer notes: Ground zero for Phoenix's logistics boom. A-1 parcels along I-10 (west Valley) and I-17 (north/south) are among the most sought-after development sites in the metro. Spec warehouse construction has been intense, driven by e-commerce, semiconductor supply chain, and nearshoring. Land prices along freeway corridors have increased dramatically.

A-2 — Heavy Industrial

The most permissive industrial district, allowing heavy manufacturing, processing, and industrial operations. Designed for areas well-separated from residential neighborhoods.

Typical uses: Heavy manufacturing, Chemical processing, Concrete/asphalt plants, Salvage yards, Large-scale warehousing, Truck terminals

Max height: 75 ft. Min lot size: 10,000 sq ft. Setbacks: Front: 20 ft, Side: 0 ft, Rear: 0 ft. Lot coverage: 80%. Parking: 1 per 1,000–2,000 sq ft (varies by use).

Developer notes: Reserved for the heaviest industrial uses. Found in the West Phoenix industrial corridor (Buckeye Road/I-10), South Phoenix, and the Sky Harbor area. A-2 land is increasingly valuable as logistics demand expands, but environmental due diligence is critical — many A-2 sites carry legacy contamination.

PUD — Planned Unit Development

A flexible zoning tool that allows developers to create custom development standards for large or complex projects. PUDs are negotiated on a project-by-project basis with City Council approval.

Typical uses: Master-planned communities, Mixed-use developments, Urban infill with custom standards, Large-scale commercial or residential projects

Max height: Negotiated per project. FAR: Negotiated per project. Min lot size: Negotiated per project. Setbacks: Negotiated per project.

Developer notes: The most commonly used entitlement tool for large projects in Phoenix. PUDs offer maximum flexibility — density, height, setbacks, use mix, and design standards are all negotiable. Nearly every major mixed-use and master-planned development in Phoenix is entitled under PUD. The trade-off is a longer timeline (6–12+ months) and community engagement requirements.

P-1 — Passenger Automobile Parking

Dedicated to parking lots and parking structures. Applied to parcels used primarily or exclusively for off-street parking to serve surrounding commercial or institutional areas.

Typical uses: Surface parking lots, Parking garages, Park-and-ride facilities

Max height: 56 ft (structures). Setbacks: Front: 10 ft, Side: 5 ft, Rear: 5 ft.

Developer notes: P-1 parcels in downtown and Midtown are potential redevelopment targets as surface parking becomes an increasingly inefficient land use. Rezoning P-1 to C-2, R-5, or PUD for mixed-use development is a common play in high-value areas.

Downtown Phoenix Plan Area

Special planning area covering the downtown core with provisions for increased height, density, and reduced parking requirements to support urban development and a walkable, transit-oriented environment.

Affected areas: Bounded roughly by I-10, I-17, and the railroad tracks — includes Downtown Core, Copper Square, Warehouse District, and Roosevelt Row

Key restrictions: Height bonuses available above base zoning in exchange for design quality and community benefits; Reduced parking requirements near light rail stations; Ground-floor activation requirements for street-facing facades; Pedestrian-oriented design standards for streetscape

Developer implication: The most favorable regulatory environment for high-density development in Phoenix. Height and density beyond base zoning are achievable through the Downtown Plan process. Projects here benefit from reduced parking requirements and strong city support for urban infill.

Transit-Oriented Development (TOD) Overlay (TOD)

Applied along the Valley Metro light rail corridor to encourage higher-density, mixed-use development within walking distance of stations. Provides density bonuses and relaxed standards to promote ridership and reduce auto dependence.

Affected areas: Properties within 1/4 to 1/2 mile of Valley Metro light rail stations along Central Avenue, Washington Street, and extensions to Tempe/Mesa

Key restrictions: Reduced or eliminated minimum parking requirements within 1/4 mile of stations; Density bonuses for residential development near stations; Pedestrian connectivity and streetscape requirements; Encouraged ground-floor commercial or active uses

Developer implication: Light rail station areas are the highest-priority sites for the city. Developers can secure parking reductions of up to 50% and density bonuses. The Central Avenue corridor from Camelback south through Midtown to downtown is the most active TOD investment zone in Phoenix.

Adaptive Reuse Overlay

Provides streamlined permitting and relaxed development standards for projects that convert existing buildings to new uses — particularly residential, restaurant, creative office, and cultural uses in the downtown core and historic districts.

Affected areas: Downtown Phoenix, Roosevelt Row, Warehouse District, Grand Avenue, and designated historic districts

Key restrictions: Building must be an existing structure — not new construction; Reduced or waived parking requirements for adaptive reuse projects; Relaxed setback and open space standards; Building code flexibility for historic structures

Developer implication: One of the best incentive programs in Phoenix for creative developers. The parking and code flexibility can save hundreds of thousands in project costs. Roosevelt Row and the Warehouse District have been transformed through this program. Look for underutilized commercial or industrial buildings in eligible areas.

Historic Preservation (HP) Overlay (HP)

Applied to designated historic districts and individual landmarks to preserve architectural and cultural character. Requires design review for exterior modifications.

Affected areas: Willo, Encanto-Palmcroft, Roosevelt, F.Q. Story, Coronado, and other designated historic neighborhoods

Key restrictions: Exterior alterations require Historic Preservation Commission review; Demolition of contributing structures requires approval and is rarely granted; New construction must be compatible with neighborhood character; Additional design review adds time to permitting

Developer implication: Historic preservation adds regulatory complexity and design review time. However, properties in HP districts can qualify for federal and state historic tax credits (up to 20% federal + Arizona state credits for qualifying properties), which can significantly improve project economics for rehabilitation projects.

Planned Community District (PCD)

Applied to large master-planned communities that encompass multiple land uses, open space systems, and phased development. Functions similarly to a PUD but at a larger, community-wide scale.

Affected areas: Desert Ridge, Ahwatukee Foothills, Estrella Mountain Ranch, Norterra, and other master-planned areas

Key restrictions: Development governed by an approved master plan and development agreement; Phasing requirements and infrastructure obligations; Open space and amenity commitments; Design guidelines specific to each community

Developer implication: PCDs offer long-term development certainty within an approved framework. For developers looking to build within existing PCDs (like Desert Ridge), the entitlement pathway is generally smoother since the master plan is already approved. Remaining developable parcels within established PCDs can be attractive for their reduced entitlement risk.

Industrial/Logistics Boom Along I-10 and I-17 Corridors

Phoenix has become one of the nation's top industrial markets, driven by e-commerce fulfillment, semiconductor supply chain (TSMC, Intel), and nearshoring from Mexico. A-1 zoned land along the I-10 (Buckeye/Goodyear), I-17 (Deer Valley/north), and Loop 303 corridors has seen explosive demand. Spec warehouse construction has outpaced almost every other metro. Developers with entitled A-1 land in these corridors hold premium positions.

Central Avenue Light Rail Corridor Is Phoenix's Densification Spine

The Valley Metro light rail along Central Avenue from Dunlap to downtown is driving a wave of multifamily and mixed-use development. TOD overlay density bonuses and parking reductions make station-area parcels pencil better than comparable sites elsewhere. Midtown (Thomas to Camelback on Central) and Uptown (Camelback to Northern on Central) are the most active investment zones. Additional rail extensions continue to expand the opportunity map.

PUD Zoning Offers Maximum Flexibility for Large Projects

Phoenix's PUD process is well-established and heavily used by developers pursuing projects that don't fit neatly into base zoning districts. PUDs allow custom density, height, setbacks, and use mix in exchange for design quality and community benefits. The 6–12 month timeline is longer than standard rezoning, but the flexibility typically justifies the investment for projects exceeding 5–10 acres.

Adaptive Reuse Ordinance Favors Creative Redevelopment

Phoenix's adaptive reuse program provides parking waivers, code flexibility, and streamlined permitting for converting existing buildings to new uses. The program has driven the revitalization of Roosevelt Row, the Warehouse District, and Grand Avenue. Developers converting old industrial, office, or commercial buildings into residential, restaurants, or creative space can save significantly on both parking and code compliance costs.

Opportunity Zones in South Phoenix and Downtown

Federally designated Opportunity Zones in South Phoenix and the downtown core offer capital gains tax benefits for long-term investment. South Phoenix is an emerging market with lower land costs, proximity to Sky Harbor Airport, and improving infrastructure. Downtown OZ parcels near light rail benefit from both tax incentives and TOD density bonuses — a powerful combination for patient capital.

Sky Harbor Flight Path Restricts Height in South-Central Phoenix

Phoenix Sky Harbor International Airport's flight paths impose FAA Part 77 height restrictions across large swaths of south-central Phoenix. Properties south of downtown and east toward Tempe can face strict height caps that override base zoning allowances. Always check FAA obstruction surfaces before acquiring sites in the Sky Harbor vicinity — failure to do so has killed multiple projects at the entitlement stage.

How does zoning work in Phoenix?

Phoenix uses a traditional Euclidean zoning system with approximately 35 base districts covering residential, commercial, industrial, and special-purpose categories. Each district specifies permitted uses, height, setbacks, lot coverage, and density. Overlays and stipulations can modify base zoning on a parcel-by-parcel basis. The Phoenix Zoning Ordinance is administered by the Planning and Development Department.

What is PUD zoning and why is it so common in Phoenix?

Planned Unit Development (PUD) is a flexible zoning tool that allows developers to negotiate custom development standards — density, height, setbacks, use mix — in exchange for design quality and community benefits. PUDs require City Council approval and typically take 6–12 months. Nearly every major mixed-use and master-planned development in Phoenix uses PUD zoning because it offers more flexibility than base districts.

How long does a typical rezoning take in Phoenix?

Standard rezoning cases typically take 4–6 months from application to City Council hearing. PUD cases can take 6–12+ months due to the additional design review and negotiation involved. Contested cases or those requiring neighborhood engagement can extend timelines significantly.

What are the parking requirements in Phoenix?

Phoenix maintains minimum parking requirements that vary by use: typically 2 spaces per dwelling unit (SF), 1.5–2 per unit (MF), 1 per 250 sq ft (retail), and 1 per 300 sq ft (office). Reduced parking is available within TOD areas near light rail stations (up to 50% reduction) and for adaptive reuse projects. PUDs can negotiate custom parking ratios.

What is the Adaptive Reuse Ordinance?

Phoenix's Adaptive Reuse Ordinance provides streamlined permitting and relaxed standards for converting existing buildings to new uses — especially residential, restaurant, and creative office uses. Benefits include reduced or waived parking requirements, building code flexibility, and expedited review. The program has been a catalyst for revitalizing downtown, Roosevelt Row, and the Warehouse District.

Are there Opportunity Zones in Phoenix?

Yes. Federally designated Opportunity Zones exist in South Phoenix, the downtown core, and several other census tracts. These zones offer capital gains tax deferral and reduction for qualified investments held for at least 5–10 years. Combined with TOD overlays and adaptive reuse incentives in downtown, OZ benefits can significantly improve project returns for patient investors.

What height can I build in downtown Phoenix?

Downtown Phoenix has no single height limit — it depends on the base zoning district, the Downtown Phoenix Plan provisions, and any applicable overlays or stipulations. R-5 allows up to 250 ft with a use permit. PUD-zoned projects can negotiate higher. The main constraint is the Sky Harbor Airport flight path, which imposes FAA height restrictions on some parcels south and east of downtown.

Does Phoenix allow ADUs (accessory dwelling units)?

Yes. Arizona SB 1162 (2023) legalized ADUs statewide on any single-family residential lot. Phoenix has adopted implementing regulations allowing one ADU per lot, subject to size, height, and setback standards. This applies to all R1-series and RE-zoned parcels throughout the city.
