Naming convention
lot-size-encoded-sf

Peoria uses R1-# single-family nomenclature where the numeric suffix encodes minimum lot size in 1,000s of sf (R1-6 = 6,000 sf, R1-8 = 8,000, R1-10 = 10,000, R1-12 = 12,000, R1-18 = 18,000, R1-35 = 35,000, R1-41 = 41,000). Same transparent convention as Glendale/Chandler/Gilbert Phoenix-metro peers. Commercial uses C-1 through C-4 plus OP (Office Professional); industrial uses IL/GI/IP; multifamily uses R-3/R-4/R-5 (density-tier encoded). MAAMF (Military Airport & Ancillary Military Facility) for Luke AFB is the single most restrictive overlay in the city (shared jurisdictionally with Glendale and southern Surprise).

State preemptions

AZ HB 2720 — ADU by-right (2024)applies
Qualifying condition
Statewide preemption applies to all AZ cities. Peoria has single-family residential zones (R1-41, R1-35, R1-18, R1-12, R1-10, R1-8, R1-6) subject to the mandate. Peoria population ~205k well above threshold.
AZ HB 2721 / HB 2330 — Middle Housing by-right (2024)applies
Qualifying condition
Statewide mandate. Cities must permit middle housing (duplex/triplex/fourplex/townhouses) by-right in SF zones within 1 mile of CBD by Jan 2026. Peoria CBD anchor is Old Town Peoria (Grand Ave / Washington St); 1-mile buffer covers portions of R1-6, R1-8, R1-10, R1-12 base zones surrounding Old Town. Parcels inside MAAMF boundary (southwestern Peoria) excluded via federal carve-out.
AZ SB 1313 — Parking Minimums Preemption (2024)applies
Qualifying condition
Statewide; limits municipal ability to impose parking minimums on multifamily, mixed-use, and transit-adjacent residential. Peoria's R-3/R-4/R-5 multifamily districts and any downtown DMU overlay mixed-use parcels subject to preemption.
AZ HB 2110 — Commercial-to-Residential Adaptive Reuse (2024)applies
Qualifying condition
Statewide mandate; ministerial approval of commercial-to-residential conversions without public hearing. Peoria pop ~205k meets threshold. C-1/C-2/C-3/C-4/OP zoned parcels and underutilized commercial stock along Bell Rd, 83rd Ave, Grand Ave corridors eligible.
AZ HB 2297 — Residential Conversion Streamlining (2024)applies
Qualifying condition
Statewide companion to HB 2110; additional provisions for converting commercial/office to residential with streamlined approval.
AZ HB 2447 — Ministerial Site-Plan Approval (2024)applies
Qualifying condition
Statewide; requires administrative (non-hearing) approval of site plans, development plans, plats based on objective standards. Companion law to HB 2721 middle-housing.
AZ Prop 207 — Private Property Rights Protection Act (2006)applies
Qualifying condition
Statewide; requires compensation for regulations that reduce property value. Peoria is subject along with all AZ municipalities.
Federal / USAF — Luke AFB MAAMF Military Airport Preemption (ARS §28-8481)applies
Qualifying condition
Federal preemption layer enforced via AZ state statute. Luke Air Force Base is an active military installation (F-35A primary training base). FAA Part 77 imaginary surfaces and USAF AICUZ noise contours preempt local residential density and height. ARS §28-8481 requires Maricopa County cities within MAAMF boundary (Glendale, Peoria, Surprise, Goodyear) to adopt compatibility overlays. Peoria's southwestern quadrant lies within the MAAMF boundary.

notesv1 Chapter-21 extraction re-verified and upgraded to v2 schema. NOTE: a 2026-04-19 intermediate pass had incorrectly re-labeled this as Chapter 14 per unverified user instruction; corrected back to Chapter 21 same day after AMLegal mirror + peoriaaz.gov Google site-scoped search confirmed 'Chapter 21 ZONING' is the current chapter (Chapter 14 was the pre-1976 predecessor). High-confidence claims preserved: MAAMF residential prohibition + ARS §28-8481 authority; 8-entry state preemption manifest with Peoria-specific qualifying narratives; FEMA NFIP standard floodplain adoption; ADWR AMA 2 and Assured Water Supply framework; lot-size-encoded R1 naming; PAD-dominance pattern; 2023–2025 downtown amendment activity. Partials: base district dimensional tables (R1-#, R-3–R-5, C-1–C-4, OP, IL/GI/IP) carried from v1 extraction with explicit p §21.XX partial-citation tags pending browser-based chapter-level retrieval (platform 403 blocks scripted fetch).
