What Arizona's housing laws do here
/ STATE LAW
Arizona's ADU law applies in Peoria. The 2020 census population was 190,985, above the 75,000 threshold in A.R.S. § 9-461.18, so the statute binds the city.
A.R.S. § 9-462.13, the middle-housing law, uses the same threshold and also binds Peoria.
Peoria's implementing ordinances and current zoning requirements have not been independently verified. Confirm them with the City before planning.
About 6.8% of Peoria's area is inside the Luke Air Force Base vicinity. No part of the city falls inside a mapped noise contour or accident potential zone.
Arizona's ADU statute (A.R.S. § 9-461.18(G)) and middle-housing statute (A.R.S. § 9-462.13(D)(8)) exclude qualifying territory near a military airport as defined in A.R.S. § 28-8461. The county's mapped Luke layers have not been compared with that statutory boundary. The percentage reported here is an area calculation, not a parcel-level legal conclusion. Confirm whether an airport-area exclusion applies to the parcel before designing an ADU or duplex.
What is already built in Peoria
/ THE HOUSING STOCK
Peoria has 59,152 single-family parcels. The middle one was finished in 1999, has 1,999 square feet, and sits on 0.175 acres. Thirty-four percent have a pool.
Peoria's 2019 municipal planning area is 233.56 square miles against 180.61 square miles of city — 52.98 square miles, or 22.7%, is planned for but not annexed. If your parcel is in that band today, the county permits it.
Housing figures are counted from the Maricopa County Assessor parcel file on September 2, 2026, restricted to single-family parcels and scoped by taxing jurisdiction rather than by mailing address.
