Overview

Code type
euclidean
Naming convention
mixed

R1-N encodes minimum lot size in thousands of square feet (R1-5 = 5,000 sf; R1-190 = 190,000 sf). This is NOT inverse — higher number = larger lot = lower density. MF districts use density-tier naming (R-2 two-family, R-3 medium, R-4 townhouse, R-5 multiple-family). Commercial uses C-N format (C-1 neighborhood, C-2 central business, C-3 highway, C-4 general, C-O office, C-S regional shopping). Overlays use acronym tags (ESL, F-O, HP, DO, PBD). Code is Euclidean with heavy overlay-driven environmental regulation — ~72% of land area sits under the ESL+F-O dual overlay. | naming_convention_raw=hybrid ; sub_flags_raw=[arizona, lot-size-encoded-sf, heavy-overlay, heavy-recent-amendment]

Worth knowing
  • R1 naming encodes minimum lot size in 1,000s of sf (R1-5 = 5,000 sf through R1-190 = 190,000 sf / ~4.4 acres). Not inverse — higher number = larger lot = lower density. The R1-190 estate district is unusual in US zoning and reflects the ranch character of older north Scottsdale.
  • ESL + F-O overlays cover ~134 of Scottsdale's 185 sq mi (~72% of city area). One of the most extensive environmental overlay systems of any US city; most undeveloped land in Scottsdale sits under this dual overlay.
  • F-O paint Light Reflectance Value shall not exceed 35%. One of the most restrictive exterior color standards in the US — effectively eliminates white, cream, and most light pastels as primary exterior paint colors in the Foothills Overlay.

Scottsdale Airport Part 77 (federal imaginary surfaces)
AP
FAA 14 CFR Part 77 (federal) — implemented through ARS §28-8486 (airport-noise/interference disclosure); local building/zoning review incorporates Part 77 surfaces around Scottsdale Municipal Airport (SDL).

Properties within the Part 77 imaginary surfaces (primary, approach, transitional, horizontal, and conical) surrounding Scottsdale Airport (KSDL). Primary surface extends 1,000 ft beyond each runway end; approach surfaces extend up to 10,000 ft at a 50:1 slope (non-precision instrument runway 3/21).

State preemptions

Qualifying condition
Scottsdale population = 248,321 (World Population Review 2026; Census ACS 5-yr 2019-2023 ~243,821; City DEMOGRAPHICS 2024 report ~244k). All estimates exceed the 75,000 threshold for the HB 2720 ADU expansion (the 2024 HB 2297 variant; 2025 HB 2928 refined airport exemptions). Tribal land status = non-tribal (Scottsdale is a non-tribal municipality; the Salt River Pima-Maricopa Indian Community borders but is not within Scottsdale). Scottsdale implemented through Ordinance 4687 adopted 2025-09-30 and January 2026 zoning amendments. | title=HB 2720 — Accessory Dwelling Units By-Right (A.R.S. §9-461.18) ; effect_on_city=By-right ADU permitting in all residential districts. Scottsdale's Ord. 4687 permits attached + detached ADU + (on lots ≥1 ac) one additional restricted-affordable detached ADU, first ADU ≤1,000 sf or 75% of main residence, 2nd/3rd ≤500 sf each. Parking waiver, owner-occupancy exception for non-rented ADUs, separate utility metering. AZ airport operating vicinity carve-out remains — Scottsdale Airport (SDL) Part 77 imaginary surfaces and >65 dB noise zones retain federal restrictions.
Qualifying condition
Scottsdale population 248,321 exceeds both the 30,000 base threshold AND the 70,000 tier-up threshold for full duplex/triplex/fourplex by-right. Non-tribal. Majority of R1-5 through R1-190 SF zones are affected. Scottsdale amended the zoning ordinance in January 2026 to comply. | title=HB 2720 — Middle Housing By-Right in Single-Family Zones ; effect_on_city=Must allow duplex/triplex/fourplex by-right in majority of SF zones. Cannot apply design standards that effectively prohibit middle housing. Scottsdale's January 2026 amendment (per legislative updates page) permits middle housing within 1 mile of Old Town (Central Business District) and on ≥20% of lots in new SF developments >10 contiguous acres. Federal conflict flagged for parcels within SDL Part 77 surfaces.
Qualifying condition
Population 248,321 ≥70,000 threshold. Non-tribal. Applies to residential SF zones (R1-5 through R1-190). | title=HB 2721 — Minimum Lot Size Reductions ; effect_on_city=Requires Scottsdale to permit minimum lot size ≤5,000 sf and lot width ≤50 ft in the majority of SF zones. Scottsdale's smallest R1 is R1-5 (5,000 sf), already at cap — law floors but does not further reduce. Tier-up thresholds for R1-7, R1-10, R1-18 (subset must drop to 5,000 sf minimum in majority of SF zones) are what actually reshape the city's R1 palette. Federal conflict flagged for SDL Part 77 parcels.
Qualifying condition
Non-tribal. Commercial, mixed-use, and office base zones exist (C-1, C-2, C-3, C-4, C-O, C-S, S-R, S-S, PCC, PNC, PRC, PCoC). Ministerial approval pathway for commercial-to-residential conversion required. | title=HB 2110 — Commercial-to-Residential Adaptive Reuse ; effect_on_city=Ministerial approval pathway (no public hearing) for conversion of existing commercial/office buildings to residential use. Applies to C-1 through C-S, C-O, S-R, S-S and PCC/PNC/PRC/PCoC mixed-use districts. HB 2297 caps adaptive reuse at 10% of existing buildings in the zone. Federal conflict flagged on commercial parcels near SDL Part 77 surfaces.
AZ-PROP207-2006applies
Qualifying condition
All AZ municipalities. Scottsdale has no known Prop 207 takings-claim history that has overturned a major recent zoning action, but the statute's chilling effect is active statewide. | title=Proposition 207 — Private Property Rights Protection Act ; effect_on_city=Requires Scottsdale to compensate property owners when a land-use regulation reduces property value. Not a field-preemption (trigger_predicate: never in state-overlays/arizona.json) but a chilling factor on downzoning, ESL tightening, and restrictive overlay expansion. Scottsdale's ESL/F-O regime predates Prop 207 (1991 ESL adoption) so is grandfathered; subsequent tightening has proceeded cautiously.
FEDERAL-PART77-SDLapplies
Qualifying condition
Scottsdale Airport (KSDL) is an active general aviation airport with runway 3/21 and published instrument approach procedures. Part 77 primary, approach, transitional, horizontal, and conical surfaces extend up to ~10,000 ft beyond runway ends. Affected parcels include portions of Airpark (north-central Scottsdale), Raintree corridor, and parcels between Pima Rd and Hayden Rd north of Frank Lloyd Wright Blvd. | title=FAA 14 CFR Part 77 — Scottsdale Airport imaginary surfaces (federal overlay, not a state preemption) ; effect_on_city=Federal height restrictions via Part 77 imaginary surfaces. Structures penetrating surfaces trigger FAA Form 7460-1 notice and possible hazard determination. State-law middle-housing/ADU preemptions (HB 2720/2721/2297/2110/2928) each contain airport operating vicinity carve-outs; on parcels under SDL Part 77 surfaces, federal height caps override any state preemption that would permit taller/denser structures. Modeled as federal_state_conflict to flag these parcels for site-level review. ; preempting_law=14 CFR Part 77 ; preempted_value=state-law middle-housing/ADU height and density expansions near SDL ; preempted_effective_date=1965-05-01

Quirks & notes

  • R1 naming encodes minimum lot size in 1,000s of sf (R1-5 = 5,000 sf through R1-190 = 190,000 sf / ~4.4 acres). Not inverse — higher number = larger lot = lower density. The R1-190 estate district is unusual in US zoning and reflects the ranch character of older north Scottsdale.
  • ESL + F-O overlays cover ~134 of Scottsdale's 185 sq mi (~72% of city area). One of the most extensive environmental overlay systems of any US city; most undeveloped land in Scottsdale sits under this dual overlay.
  • F-O paint Light Reflectance Value shall not exceed 35%. One of the most restrictive exterior color standards in the US — effectively eliminates white, cream, and most light pastels as primary exterior paint colors in the Foothills Overlay.
  • Historic Property (HP) designations are parcel-specific, not district-wide. Each individual property on the Scottsdale Historic Register is its own HP overlay; Scottsdale has no area-wide historic districts of the kind most large cities use.
  • The Downtown Plan was renamed the Old Town Plan after 2018-08-01. Code references still use 'Downtown Plan'; the two terms are interchangeable per §3.100 definitions.
  • Scottsdale Airport (SDL) Part 77 imaginary surfaces create a federal overlay over Airpark and surrounding north-central Scottsdale. This is NOT a state preemption and NOT an Appendix B overlay — it is a federal airspace hazard surface. State HB 2720/2721/2297 carve-outs for airport operating vicinity interact with these federal surfaces; profile flags federal_state_conflict on affected parcels.
  • Scottsdale adopted Ord. 4687 on 2025-09-30 to comply with HB 2928 (ADU expansion); further January 2026 amendments address HB 2720 (middle housing), HB 2721 (min lot size), and HB 2110 (adaptive reuse). Legislative updates page maintained at scottsdaleaz.gov/planning-development/legislative-updates.
  • Scottsdale ADU ordinance permits up to 3 ADUs on lots ≥1 acre if at least one is restricted-affordable. This is more permissive than the state HB 2720 floor, which requires only 1 attached + 1 detached.
  • Development Review Board (DRB) has cross-cutting design-review jurisdiction across F-O exceptions, Downtown design, and historic properties. Single body consolidates design review that most cities split between planning commission and staff.
  • Commercial district count is large (C-1, C-2, C-3, C-4, C-O, C-S) plus planned variants (PCC, PNC, PRC, PCoC, PCP). Reflects Scottsdale's stratification of commercial by scale (neighborhood → regional) and form (general vs. planned).
  • S-R (Service Residential) and S-S (Support Services) are hybrid mixed-use/transition districts specific to Scottsdale — less common naming among AZ cities.
  • R-4R (Resort/Townhouse) is a resort-hybrid district enabling hotel/resort uses alongside townhouse residential — a uniquely Scottsdale typology reflecting the city's tourism economy.

overlays have parameters trigger confidencepassed6/6 overlays (ESL, F-O, HP, DO, PBD, SDL-PART77) each carry non-empty parameters object (≥2 keys), explicit geographic_trigger string, status, and citation. ESL/F-O/HP confirmed; DO and PBD carry status=partial with search_performed + retrieval_failure_reason narratives; SDL-PART77 carries status=federal_state_conflict with federal_overlay_refs populated.
preempt section city specificpassedstate_preemptions_applicable[] contains 6 per-law entries (HB 2720 ADU, HB 2720 Middle Housing, HB 2721 Min Lot Size, HB 2110 Adaptive Reuse, Prop 207, Federal Part 77-SDL). Each entry has qualifying_condition_checked with Scottsdale-specific numeric inputs (population 248,321 vs state thresholds 30k/70k/75k; non-tribal; Ord. 4687 local implementation) and effect_on_city statement. Not a link-stub — link to state-overlays/arizona.json is in addition to per-law rows.
