Amarillo uses category-prefixed alphanumeric codes: A (agricultural), R-1/R-2/R-3 (residential by density), MD (moderate density), MF-1/MF-2 (multifamily by density), MH (manufactured home), O-1/O-2 (office), NS/GR/LC/CB/HC (commercial by intensity), I-1/I-2 (industrial), PD (planned development). Confirmed against Table 1, Sec. 4-10-174 of Chapter 4-10.
Worth knowing
Amarillo zoning Table 1 (Sec. 4-10-174) expresses MAX HEIGHT in STORIES, not feet. This record converts at 10 ft/story per §4-10-194(b)(1) which uses '3 stories or less' as the threshold for special height regs (cooling towers etc. capped at 40 ft, with 1-ft side/front/rear setback added per ft above 3 stories). MF-2, O-2, CB, HC, I-1, I-2 all carry 'unlimited*' height for tall structures, with progressive setback step-backs per §4-10-171(b)(2) and §4-10-172(b)(4).
CB (Central Business) District allows 100% lot coverage and zero front yard for nonresidential uses (Table 1). Parking schedule of §4-10-211(2) explicitly EXEMPTS CB from the standard nonresidential parking-by-use schedule.
Dual-county straddle: Amarillo spans Potter (~121K, 2020) and Randall (~146K, 2020) counties. SB 840 county predicate (>=300K) evaluated per-county, not summed — law does NOT apply to Amarillo.
Geographic boundary defined in Sec. 4-10-120(b): downtown Amarillo bounded by Washington Street (W), Madden/LA Wells Subdivision (N), I-40 (S), and BNSF railway property/SE 5th Avenue (E). Overlay supplements the underlying base zoning district (typically CB Central Business). Within the District a Certificate of Appropriateness from the Downtown Design Review Board (or Planning Department for minor items) is required prior to building permit issuance for new construction, exterior major modifications, parking lots, or public ROW/common area work.

Full-text search of the Amarillo Code of Ordinances Chapter 4-10 (Article IV district regulations + Table 1) on amarillo.gov for 'airport overlay', 'airport zone', 'airport hazard', 'Part 77' returned zero matches. No municipal airport overlay district exists in the zoning code. FAA Part 77 imaginary surfaces around KAMA (Rick Husband Amarillo International) are federal and apply by operation of FAA regulation, not via a municipal overlay district.

The City of Amarillo participates in the NFIP and floodplain construction is regulated under federal NFIP standards and a separate municipal floodplain ordinance outside Chapter 4-10 (zoning), but no Floodplain Overlay District exists within the zoning code itself.

Full-text search of Chapter 4-10 (Article IV) for 'historic preservation', 'historic district', 'Route 66 overlay' returned zero matches as a separate overlay district. Historic preservation review for downtown is folded into the Downtown Urban Design Overlay (DUD, Sec. 4-10-120 to 4-10-150), which references 'historic buildings restored to the original state' as one Planning-Department-approvable category. No standalone HP overlay district exists. Prior v1-converter HDO overlay (with separate Downtown/Route 66/San Jacinto sub-districts) was a fabrication.

SB 15 (small-lot deregulation) applies statewide to lots <=4,000 sf; no population or county threshold. Amarillo is subject per-parcel to setback, parking, height, and FAR waivers on qualifying small lots. City retains authority over use restrictions and life safety.
Source
Texas SB 15 (88th Legislature) statute text.
Effect
On lots <=4,000 sf: city setback, parking ratio, height, and FAR regulations are waived or limited.
City pop 200,393 (2020 Census decennial) >= 150,000 threshold MET. County pop gate: Potter County ~121,000 (2020 Census) AND Randall County ~146,714 (2020 Census); neither county independently meets the >=300,000 threshold. SB 840 county predicate requires a single county >=300k; Amarillo's dual-county straddle does NOT sum across county lines per the statute's trigger language. Result: county gate FAILS, so the law does NOT apply to Amarillo parcels.
Source
U.S. Census Bureau 2020 decennial (Amarillo city; Potter County; Randall County). Texas SB 840 statute text from capitol.texas.gov.
Effect
No preemption — Amarillo retains full local control over MF use allowance, density, height, setback, and parking on commercial/office/retail/warehouse/MU parcels.

Ord. No. 7469, § 2, 8-12-2014 (most recent ordinance amendment cited within Article IV district regulations)
Quirks & notes
Amarillo zoning Table 1 (Sec. 4-10-174) expresses MAX HEIGHT in STORIES, not feet. This record converts at 10 ft/story per §4-10-194(b)(1) which uses '3 stories or less' as the threshold for special height regs (cooling towers etc. capped at 40 ft, with 1-ft side/front/rear setback added per ft above 3 stories). MF-2, O-2, CB, HC, I-1, I-2 all carry 'unlimited*' height for tall structures, with progressive setback step-backs per §4-10-171(b)(2) and §4-10-172(b)(4).
CB (Central Business) District allows 100% lot coverage and zero front yard for nonresidential uses (Table 1). Parking schedule of §4-10-211(2) explicitly EXEMPTS CB from the standard nonresidential parking-by-use schedule.
Dual-county straddle: Amarillo spans Potter (~121K, 2020) and Randall (~146K, 2020) counties. SB 840 county predicate (>=300K) evaluated per-county, not summed — law does NOT apply to Amarillo.
ONLY ONE zoning overlay exists in Amarillo's Code Chapter 4-10: the Downtown Urban Design Overlay District (DUD), Sec. 4-10-120 to 4-10-150, adopted by Ord. No. 7223 on 2010-07-20. Pantex, Airport (FAA Part 77), Floodplain (FEMA NFIP), CAFO/feedlot, Route 66 historic, and any 'San Jacinto' historic district are NOT zoning overlays in the Amarillo Code — they are either federal regimes (FAA, FEMA, NNSA), state regulatory regimes (TCEQ for CAFO), or non-zoning municipal ordinances. The prior v1-converter overlay roster (AMA, FO, PNFO, FBO, HDO) was a fabrication and has been removed in this v2 refresh.
Prior v1-converter district roster (RM-1, RM-2, C-1, C-2, C-3, M-1, M-2) was a structural fabrication. Amarillo's actual residential MF districts are MD/MF-1/MF-2, commercial districts are NS/GR/LC/CB/HC, and industrial districts are I-1/I-2. The full code roster is A, R-1, R-2, R-3, MD, MF-1, MF-2, MH, O-1, O-2, NS, GR, LC, CB, HC, I-1, I-2, PD — 18 districts confirmed against Table 1.
Front-yard cul-de-sac override: §4-10-170(b)(9) reduces the R-1/R-2 front yard from 25 ft to 20 ft on cul-de-sac lots.
Rick Husband Amarillo International Airport (KAMA, federal FAA jurisdiction) and Pantex Plant (NNSA) are real federal infrastructure near Amarillo, but neither is reflected in the Amarillo zoning code as a municipal overlay. Builders in those areas comply with FAA Part 77 and DOE/NNSA rules independently of Chapter 4-10.
Formulas
Definitions
height
Grade to highest point of structure. Amarillo Table 1 expresses height in stories; converted at 10 ft/story per Sec. 4-10-194(b)(1) which treats 3 stories as the threshold for special height regulations.
lot_coverage
Building footprint / lot area (Sec. 4-10-173). Off-street unenclosed parking/loading not counted.
far
Gross floor area / lot area. Amarillo zoning code does NOT specify FAR; reported FAR values are inferred from coverage * stories and flagged accordingly.
du_ac
Dwelling units per gross acre. Amarillo regulates density via min lot area per dwelling unit, not du/ac directly.
setback_front
Front property line to nearest building face (Sec. 4-10-170).
setback_side
Side property line to nearest building face (Sec. 4-10-171).
setback_rear
Rear property line to nearest building face (Sec. 4-10-172).
parking
Spaces per dwelling unit unless noted (Sec. 4-10-211).

Documented gaps
FAR not specified in the Amarillo zoning code (consistent with form-by-coverage approach); FAR fields left null with documented absence.
Heights in Table 1 are in STORIES; ft conversion uses 10 ft/story per §4-10-194(b)(1). Where Table 1 says 'unlimited*' (CB, HC, I-1, I-2, MF-2 high-rise, O-2 nonres), max_height_ft is null with confirmed citation.
Industrial use parking is by use-specific schedule in §4-10-211(2); per-DU figure not applicable to industrial.
