What does R1-6 zoning mean in Phoenix?

R1-6 is Phoenix's standard single-family residence district, requiring a minimum 6,000-square-foot lot. It's the most common single-family designation in the city and, under the 2024 state ADU mandate, now permits an accessory dwelling unit by right on qualifying lots.

How do I find the zoning for a parcel in Phoenix?

Use the Phoenix Planning & Development Department's zoning verification tool or GIS zoning map, which shows the current zoning district and any overlay designations for a given address or parcel. PDD can also issue a formal zoning verification letter for transactions.

Can I build an ADU on a single-family lot in Phoenix?

Yes. Phoenix exceeds the 75,000-resident threshold under Arizona's 2024 HB 2720, so accessory dwelling units are permitted by right on qualifying single-family lots citywide, subject to the ordinance's size and setback standards.

Phoenix, AZ zoning map & districts

Phoenix zones under a traditional Euclidean ordinance administered by the Planning & Development Department, with a Zoning Adjustment Hearing Officer and Board of Adjustment handling variances and a Planning Commission and City Council handling rezonings and text amendments. The ordinance separates single-family residence districts (R1-6 through R1-43, the number denoting minimum lot size in hundreds of square feet), multifamily districts (R-2 through R-5), commercial districts (C-1 through C-3), and industrial districts (A-1, A-2), with Planned Unit Development (PUD) overlays used heavily for master-planned and infill sites.

The Phoenix Planning & Development Department maintains the zoning ordinance text and administers zoning; parcel-specific zoning is looked up through the city's PDD zoning verification / GIS zoning map application.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.

How zoning works in Phoenix

Phoenix is one of the Arizona cities directly subject to the state's 2024 ADU and middle-housing mandates (HB 2720 and HB 2721) because it exceeds the 75,000-population threshold, so single-family districts citywide now carry by-right accessory dwelling unit allowances under that mandate. Downtown and light-rail-adjacent parcels also fall under urban-form-based overlays (including the Downtown Code) that regulate building form rather than use, and Walkable Urban (WU) code provisions apply along several major corridors.

The parcel layer lands in the order demand does. Illinois went first because that's where the deals were; the next state is decided by who tells us what they're trying to underwrite.
