Overview
Euclidean base zones (A-1 agricultural, SR/R-1 single-family, R-2/R-3/R-4 multifamily, C-1/C-2/C-3 commercial, M-1/M-2 industrial) layered with overlay districts (Art. 2, §35.2.1000 et seq.). R-1-# district codes encode minimum lot size in 1,000s sf (R1-6 = 6,000 sf; SR-30 = 30,000 sf; RR-45 = 45,000 sf). PAD is the dominant mechanism for post-2000 mixed-use and Westgate-area development. The Military Airport and Ancillary Military Facility (MAAMF) overlay for Luke AFB is the single most restrictive constraint in the city. | naming_convention_raw=lot-size-encoded-sf ; sub_flags_raw=[pad-dominant, arizona-housing-bills-2024, state-preemption-active, military-airport-overlay-dominant] ; narrative_ref=narratives/glendale-az/b4c688c1-447f-47cd-9809-2e39adca5726.json
- Luke AFB MAAMF overlay prohibits all residential uses (SFD, MF, ADU) within high-noise / accident-potential zones unless Luke AFB issues a Military Compatibility Permit (MCP). This is the single largest zoning constraint in Glendale and preempts state ADU (HB 2720) and middle-housing (HB 2721) mandates via their federal-airport-noise carve-outs. Southern and southwestern Glendale parcels may appear available for residential zoning but are practically constrained by MCP requirement. — [c§35, Art. 2 MAAMF; ARS §28-8481; Luke AFB AICUZ Study]
- Single-family district naming encodes minimum lot size in thousands of sf (R1-6 = 6,000 sf; R1-10 = 10,000 sf; SR-30 = 30,000 sf; RR-45 = 45,000 sf). Transparent convention shared with Phoenix-metro peers (Scottsdale, Gilbert, Chandler variants). Developers can determine lot-size constraint from district name without consulting code tables. — [c§35, Art. 2]
- R1-6 is a frozen 'legacy hold' district. UDC limits new R1-6 rezoning to special circumstances with documented findings — functionally a non-growth zone. Likely motivated by Prop 207 exposure to block downzoning of larger parcels, combined with policy preference to direct new small-lot SFD to R1-4 patio-home product. Developers should not plan new projects expecting R1-6 as an entitlement. — [c§35, Art. 2 R1-6 purpose statement; AZ Prop 207 (2006)]

Overlays
Non-contiguous parcels within Luke AFB high-noise (DNL >=65 dB) and accident-potential zones (APZ-1 and APZ-2) as delineated on the adopted Luke AFB / Maricopa County compatibility map. Concentrated in southern and southwestern Glendale; shared with Peoria jurisdictionally. Arizona Superior Court (State v. Maricopa County) + Maricopa County compliance certification per ARS §28-8481(I) in 2010.
Properties along designated centerline-setback arterials where future roadway widening or scenic corridor preservation is planned. Applies citywide to identified major arterials (Glendale Ave, Bell Rd, 59th Ave, Loop 101 adjacent parcels, among others).
Old Towne Historic District — approximately 10 square blocks in downtown Glendale centered on Glendale Avenue and 58th Drive. Also applies to individually designated historic properties citywide.
FAA Part 77 imaginary surfaces and AICUZ noise contours near Glendale Municipal Airport (civilian general-aviation) and overlap zones with Phoenix-area regional airports. Distinct from MAAMF — AIO applies to civilian aviation, MAAMF to military.
FEMA Special Flood Hazard Areas (SFHAs) with 1% annual chance of inundation (Zone A/AE), plus 500-year zones (Zone X shaded). Limited mapped floodplain in Glendale — primary areas near Westgate district and southwest industrial zones near Luke AFB; Agua Fria and New River corridor on western edge.
Applied throughout Glendale via City Council rezoning action. Most post-2000 mixed-use, commercial, and residential master-planned developments are PAD-governed — Westgate Entertainment District, Glendale 303, Evergreen Loop 101, Centerline on Glendale, Parkway 303 West, Sarival 303.
1-mile CBD buffer centered on Old Towne Glendale, extending to SF-zoned parcels within the radius. Applies to SR-17, R1-10, R1-8, R1-7, R1-6, R1-4 base zones within buffer. Exempts MAAMF-overlaid parcels (federal preemption).
Commercial (C-2, C-3) and multifamily (R-3, R-4) parcels undergoing adaptive reuse of nonconforming or underutilized structures to residential or mixed-use. Glendale pop >75,000 threshold for HB 2110/2297 applicability met.

Quirks & notes
- Luke AFB MAAMF overlay prohibits all residential uses (SFD, MF, ADU) within high-noise / accident-potential zones unless Luke AFB issues a Military Compatibility Permit (MCP). This is the single largest zoning constraint in Glendale and preempts state ADU (HB 2720) and middle-housing (HB 2721) mandates via their federal-airport-noise carve-outs. Southern and southwestern Glendale parcels may appear available for residential zoning but are practically constrained by MCP requirement. — [c§35, Art. 2 MAAMF; ARS §28-8481; Luke AFB AICUZ Study]
- Single-family district naming encodes minimum lot size in thousands of sf (R1-6 = 6,000 sf; R1-10 = 10,000 sf; SR-30 = 30,000 sf; RR-45 = 45,000 sf). Transparent convention shared with Phoenix-metro peers (Scottsdale, Gilbert, Chandler variants). Developers can determine lot-size constraint from district name without consulting code tables. — [c§35, Art. 2]
- R1-6 is a frozen 'legacy hold' district. UDC limits new R1-6 rezoning to special circumstances with documented findings — functionally a non-growth zone. Likely motivated by Prop 207 exposure to block downzoning of larger parcels, combined with policy preference to direct new small-lot SFD to R1-4 patio-home product. Developers should not plan new projects expecting R1-6 as an entitlement. — [c§35, Art. 2 R1-6 purpose statement; AZ Prop 207 (2006)]
- R1-4 is a patio-home product-type district only, NOT a standard small-lot SFD zone. Requires patio-home subdivision design: attached/detached SFD on 4,000 sf lots with rear-yard privacy guarantee, common/shared open space (HOA-maintained), functional rear yard (20-25 ft depth), and architectural coordination. Standard SFD subdivisions (detached homes, no common open space) in R1-4 will not be approved. — [c§35, Art. 2 R1-4 purpose statement]
- Centerline Overlay imposes a 15 ft building-height cap on affected parcels — effectively one story only. Applies along designated scenic corridors and future roadway-widening arterials. Overrides base district height limits regardless of zoning (R-4, C-3, M-1). Extremely restrictive; rarely waived. Any site planning on Glendale arterials (Bell Rd, Glendale Ave, 59th Ave, Loop 101 adjacent) must confirm Centerline Overlay status. — [c§35, Art. 2, §35.2.1010]
- R-2 multifamily step-down requirement: when abutting an R-1 zone, R-2 structures must be <=1 story within 50 ft of the R-1 boundary and <=2 stories within 100 ft. Protects R-1 neighborhoods from abrupt density transitions. Distinct Glendale UDC provision. — [c§35, Art. 2 R-2]
- Westgate Sports & Entertainment District (State Farm Stadium — Arizona Cardinals; Desert Diamond Arena — formerly Coyotes) is Glendale's economic anchor. Zoned mixed C-3 + PAD with special-purpose entertainment design standards. High-density mixed-use, hotels, retail, and residential integrated. Likely overlay/PAD framework; not a discrete base-zone classification. — [c§35, Art. 2 PAD; Westgate PAD ordinance]
- Old Towne Historic District (downtown, ~10 square blocks) has Historic Preservation Overlay with Certificate of Appropriateness (COA) required for exterior alterations, new construction, and demolition. Height approximately 18-25 ft in historic core. Tax-incentive / facade rehabilitation grant eligibility. Distinct from adaptive-reuse overlay pathway. — [c§35, Art. 2 HPO; Old Towne Design Guidelines]
- PAD is the dominant mechanism for post-2000 entitlement of mixed-use, large commercial, and master-planned residential projects (Glendale 303, Westgate, Evergreen Loop 101, Centerline on Glendale, Parkway 303 West, Sarival 303). Most material Glendale entitlement work flows through PAD rather than base-zone-only analysis. Prop 207 reinforces this pattern — negotiated master plans avoid Prop 207 triggers. — [c§35, Art. 2 PAD; approved PAD ordinances]
- 2024 UDC (adopted Dec 12 2023, effective Jan 12 2024) replaced prior Ordinance No. 243 framework. All pre-2024 research is superseded. UDC_12.12.23_FINAL.pdf hosted at cdnsm5-hosted.civiclive.com; consolidated code at library.municode.com/az/glendale. — [Glendale UDC adoption ordinance; UDC_12.12.23_FINAL.pdf]
- Federal-state conflict pattern: HB 2720 (ADU by-right) and HB 2721 (middle housing by-right) statutes explicitly carve out FAA-licensed and military airport noise zones >=65 dB. The Luke AFB MAAMF overlay qualifies under this carve-out. Within MAAMF, federal military compatibility preempts state housing mandates; outside MAAMF, state mandates preempt local restrictions. Glendale is the canonical example of this pattern for Arizona; Chandler and other IWA-adjacent cities apply a variant (no AFB but FAA/AICUZ carve-outs via Art. XXXV exemption language). — [AZ HB 2720; AZ HB 2721; ARS §28-8481; c§35 Art. 2 MAAMF]
