Naming convention
lot-size-encoded

naming_convention_note=Single-family codes are lot-size-encoded: R1-190 = 190,000 sq ft, R1-43 = 43,560 sq ft (1 acre), R1-35 = 35,000 sq ft, R1-10 = 10,000 sq ft, R1-8 = 8,000 sq ft, R1-6 = 6,000 sq ft. Multifamily and commercial codes use letter-code convention.

Worth knowing
  • Naming convention note: R1-35H is the hillside variant of R1-35 with substantially different front setbacks (20 ft vs 40 ft) and is distinct despite same minimum lot size (35,000 sq ft). The 'H' suffix denotes hillside, not a distinct density tier.
  • Distance-between-buildings standard in R1 districts: uniform 6 ft across all SF districts per §10.09 column. MF districts use variable standard: horizontal separation ≥ height of highest adjacent building (see §11.10 fn c).
  • Industrial districts reference 'UBC' (Uniform Building Code) for distance-between-buildings rather than a specified footage (§13.07). This is an older code citation — current building code is IBC-based per §18.14 TCCD reference to 'IBC'.

State preemptions

AZ-SB1162-NEEDS-ASSESSMENTapplies
Qualifying condition
A.R.S. §9-461.16 applies to all cities ≥1,500 population. Fountain Hills population is approximately 24,189 (2019–2023 ACS 5-year estimate), well above the 1,500 threshold. Town must publish housing-needs assessments every 5 years beginning January 1, 2025 using OEO methodology.
AZ-HB2447-ADMIN-REVIEWapplies
Qualifying condition
HB 2447 (A.R.S. §9-463.01 amendment) applies to all cities and towns regardless of population. Fountain Hills is an incorporated town subject to this preemption. Operative provisions effective January 1, 2026; preempts local procedural ordinances conditioning site plans, plats, lot splits, or design review on a public hearing. Objective, measurable standards required.
AZ-MFH-MANUFACTURED-HOUSINGapplies
Qualifying condition
A.R.S. §9-462.01(M) applies to all cities. Fountain Hills may not exclude HUD-Code manufactured homes from residential districts solely due to construction method. May apply neutral, design-compatible standards identical to site-built homes in the same district. MH (Mobile Home) Zoning District listed in §3.01 suggests some accommodation; full compliance status not verified from primary source.
AZ-STR-SHORT-TERM-RENTALapplies
Qualifying condition
A.R.S. §9-500.39 applies to all cities. Fountain Hills may not prohibit or restrict STR use based on residential classification. Town may require permits, set fees, impose health/safety standards, and regulate noise/nuisance but may not cap total STR count or impose minimum-stay requirements that effectively ban STRs. Fountain Hills is a popular resort/retirement community (near Scottsdale) with significant STR activity; noted in Maricopa County STR context.
AZ-GROUP-HOMEapplies
Qualifying condition
A.R.S. §36-582 applies to all cities. Group homes for ≤10 residents with state licensure are deemed residential uses and may not be excluded from residential districts. No evidence from primary source that Fountain Hills has non-conforming group-home exclusions.
AZ-PROP207-CHILLING-EFFECTapplies
Qualifying condition
A.R.S. §§12-1131–12-1138 (Prop 207) applies to all Arizona municipalities. Any land-use law enacted after property transfer that reduces property fair-market value triggers compensation claims. Fountain Hills's predominantly single-family zoning code and hillside protections create significant Prop 207 exposure for any downzoning or tightening of overlay standards. No Prop 207 chapter found in the current ZO; chilling effect on downzoning is operative. Applies as enforcement mechanism for all code amendments.
AZ-SB1487-ENFORCEMENTapplies
Qualifying condition
A.R.S. §41-194.01 applies to all Arizona cities and towns. Any legislator may refer Fountain Hills ordinances to the AG for preemption review; finding of violation → 30-day cure period → state-shared-revenue forfeiture. Relevant backstop for all other applicable preemptions above.
Non-applicable laws (4)
AZ-HB2720-ADUdoes_not_apply
Qualifying condition
A.R.S. §9-461.18 (HB 2720) applies only to municipalities ≥75,000 population. Fountain Hills population is approximately 24,189 (2019–2023 ACS 5-year estimate), well below the 75,000 threshold. HB 2720's by-right ADU mandate and prohibitions on owner-occupancy requirements, ADU-specific parking minimums, and design/material matching requirements do NOT apply to Fountain Hills. Town retains authority to regulate ADUs under its own zoning code.
AZ-HB2721-MIDDLE-HOUSINGdoes_not_apply
Qualifying condition
HB 2721 (middle housing in single-family zones) applies only to municipalities ≥75,000 population. Fountain Hills population is approximately 24,189 (2019–2023 ACS 5-year estimate), well below the 75,000 threshold. The mandate to allow duplexes, triplexes, fourplexes, and townhomes by-right near the CBD and in large developments does NOT apply to Fountain Hills.
AZ-HB2110-ADAPTIVE-REUSEdoes_not_apply
Qualifying condition
HB 2110 (A.R.S. §9-462.09) applies only to cities ≥150,000 population. Fountain Hills population is approximately 24,189 (2019–2023 ACS 5-year estimate), well below the 150,000 threshold. Adaptive reuse by-right mandate does NOT apply to Fountain Hills.
AZ-DARK-SKYdoes_not_apply
Qualifying condition
A.R.S. Title 49 Ch. 11 Observatory Protection Districts cover areas within 25–35 air-miles of Kitt Peak (SW of Tucson), Mt. Hopkins, Mt. Graham, Mt. Lemmon, and Lowell Observatory (Flagstaff). Fountain Hills is located in Maricopa County at lat 33.608, lon -111.738, approximately 90+ miles from Kitt Peak, 100+ miles from Mt. Lemmon/Hopkins, and 120+ miles from Lowell Observatory — outside all protection radii. State dark-sky preemption does NOT apply. Fountain Hills may adopt its own dark-sky ordinance independently.

Quirks & notes

  • Naming convention note: R1-35H is the hillside variant of R1-35 with substantially different front setbacks (20 ft vs 40 ft) and is distinct despite same minimum lot size (35,000 sq ft). The 'H' suffix denotes hillside, not a distinct density tier.
  • Distance-between-buildings standard in R1 districts: uniform 6 ft across all SF districts per §10.09 column. MF districts use variable standard: horizontal separation ≥ height of highest adjacent building (see §11.10 fn c).
  • Industrial districts reference 'UBC' (Uniform Building Code) for distance-between-buildings rather than a specified footage (§13.07). This is an older code citation — current building code is IBC-based per §18.14 TCCD reference to 'IBC'.
  • TCCD (Town Center Commercial) allows 100% lot coverage on Avenue of the Fountains corridor — effectively a form-based build-to-line requirement for the downtown pedestrian spine.
  • The 2005 ArcGIS FeatureServer 'ToFH 2005 LandUse _ Zoning' (services7.arcgis.com/tKxHAVUwBYWFvNcs) passes geometry centroid gate but has no zoning codes in TEXTSTRING field and is 20-year-old non-authoritative data. Not used.
  • Prop 207 chilling effect is operative: Fountain Hills's hillside overlay standards and low-density large-lot SF designations (R1-190, R1-43) were established before 2006 or shortly after for existing property owners, meaning any tightening of those standards would trigger Prop 207 compensation exposure. No explicit Prop 207 claims chapter found in current ZO.
  • Entertainment Overlay District (Ch. 25) and Planned Shopping Plaza Overlay (Ch. 26) are the only named overlay districts in the ZO. Town Center Commercial District (Ch. 18 / TCCD) functions as a de facto downtown overlay but is a base district, not an overlay chapter.
