26 districts. 9 overlays.

Overview

Worth knowing
  • R-1..R-7 are tier-rank indexes (R-1 is largest-lot / lowest-density) — Allen residential single-family districts use a sequential tier-rank index where R-1 is the largest-lot estate tier (40,000 sf min lot, 1 du/ac) and R-7 is the smallest-lot SF tier (5,000 sf min lot, 6.2 du/ac). The number is neither min lot in 1,000s sf (Dallas-style) nor du/ac (San Antonio-style). R-1.5 is a half-step at 30,000 sf. MF-12 / MF-18 use density-encoded numbers (12 and 18 are nominal du/ac targets achieved via 3,000 sf and 2,400 sf lot-area-per-du in § 4.15.2).
  • Cottonwood Creek overlay (CWCO) density bonus — up to 45 du/ac — Within the DD downtown district, the Cottonwood Creek overlay (CWCO) base density is 18 du/ac but may be increased to 38 du/ac (single-criterion compliance) and 45 du/ac (full-criteria compliance) per § 4.08.19.6.c. Bonuses are tied to design conditions (structured parking, ground-floor activation, open-space contribution to the downtown improvement fund, etc.) — not income-restricted affordability.
  • Community Facilities (CF) inherits dimensional standards from most-permissive adjacent district — § 4.15.3 explicitly states for CF: 'Development regulations of the most permissive adjacent district shall apply.' Because of this, CF dimensional fields cannot be expressed as static values — they resolve at site-evaluation time based on adjacent zoning.

State preemptions

Non-applicable laws (2)
unspecified preemptionunder_review
Qualifying condition
Allen city population ~113,300 (2025 Census estimate) — FAILS city-population threshold of ≥150,000 required by SB 840. Collin County population ~1,251,273 (2025) passes the county gate, but the conjunctive AND predicate fails on the city prong. Inputs: city.population=113300 (vintage: Census 2025 estimate), county.population=1251273 (vintage: Census 2025 estimate), thresholds: city≥150000 AND county≥300000. | overlay_id=TX_SB840_MF_BY_RIGHT_2025 ; preempting_law=Texas SB 840 (88th Legislature) ; reason=City population below 150,000 threshold — SB 840 multifamily by-right does not apply to Allen. City retains full zoning authority over MF approvals on commercial/office/retail/warehouse/MU parcels.
unspecified preemptionunder_review
Qualifying condition
SB 15 applies statewide to qualifying small lots (≤4,000 sf) with no city-population threshold. Allen is subject to SB 15 for any small-lot subdivision meeting the criteria. Inputs: parcel.lot_area_sf≤4000 (condition), effective 2025-09-01. | overlay_id=TX_SB15_SMALL_LOT_DEREGULATION_2025 ; preempting_law=Texas SB 15 (88th Legislature) ; preempted_fields=['min_setback_ft (waived)', 'parking_ratio (waived)', 'max_height_ft (waived)', 'max_far (waived) on lots ≤4,000 sf'] ; notes=Allen's R-7 district min lot is 5,000 sf and TH min lot is 2,160 sf; SB 15 enables sub-4,000 sf lots where a platting path exists.

Quirks & notes

  • R-1..R-7 are tier-rank indexes (R-1 is largest-lot / lowest-density) — Allen residential single-family districts use a sequential tier-rank index where R-1 is the largest-lot estate tier (40,000 sf min lot, 1 du/ac) and R-7 is the smallest-lot SF tier (5,000 sf min lot, 6.2 du/ac). The number is neither min lot in 1,000s sf (Dallas-style) nor du/ac (San Antonio-style). R-1.5 is a half-step at 30,000 sf. MF-12 / MF-18 use density-encoded numbers (12 and 18 are nominal du/ac targets achieved via 3,000 sf and 2,400 sf lot-area-per-du in § 4.15.2).
  • Cottonwood Creek overlay (CWCO) density bonus — up to 45 du/ac — Within the DD downtown district, the Cottonwood Creek overlay (CWCO) base density is 18 du/ac but may be increased to 38 du/ac (single-criterion compliance) and 45 du/ac (full-criteria compliance) per § 4.08.19.6.c. Bonuses are tied to design conditions (structured parking, ground-floor activation, open-space contribution to the downtown improvement fund, etc.) — not income-restricted affordability.
  • Community Facilities (CF) inherits dimensional standards from most-permissive adjacent district — § 4.15.3 explicitly states for CF: 'Development regulations of the most permissive adjacent district shall apply.' Because of this, CF dimensional fields cannot be expressed as static values — they resolve at site-evaluation time based on adjacent zoning.
  • Corridor Commercial (CC) allows up to 160 ft / 12 stories with stepped setback — CC permits a primary structure up to 160 ft (12 stories) per § 4.15.3 footnote (7); height above 45 ft requires a 1:1 stepped front setback (200 ft front, 100 ft side/rear). Additional CC structures are limited to 45 ft / 3 stories. This is the most permissive height in Allen's base districts; office (O) is the next-tallest at 80 ft.
  • CC properties adjacent to SH 121 — front yard 50 ft, no parking within 30 ft — § 4.15.3 footnote (8) reduces the CC front-yard setback to 50 ft for properties adjacent to Highway 121 (with parking prohibition within 30 ft of front property line) instead of the otherwise-applicable 100 ft.
  • Heavy reliance on PD ordinances — Appendix D — Allen historically uses Planned Development (PD) ordinances extensively for master-planned communities and major commercial sites. Appendix D enumerates each adopted PD ordinance; § 4.08.17 governs the PD process.
  • Design Overlay Districts No. 1 and No. 2 — both deleted — § 4.09.1 and § 4.09.2 (Design Overlay District No. 1 and No. 2) are both shown in the LDC as [deleted]. There are no currently-effective generic Article IV design overlays — design control now flows through DD § 4.08.19 and PDs.
  • A-O Agriculture-Open Space is the default zoning for newly-annexed land — Per § 4.08.1, A-O is treated as the proper classification for lease areas of undeveloped land or land newly annexed to the city until the property is rezoned to a more specific district.
  • SB 840 does not preempt Allen — Allen population (~113K) is below the 150K threshold. SB 840 multifamily-by-right on commercial/office/retail/warehouse/MU parcels does NOT apply. City retains full MF approval authority.
  • 100% masonry exterior required for all residential districts — § 4.15.2 requires 100% masonry exterior (brick, stone masonry, or stucco; cementitious fiber board does not count) on residential exteriors per district footnote (8) for TH and as a general row for all residential districts.
