Naming convention
mixed

Carrollton uses a hybrid naming convention: Single Family residential districts encode minimum lot size in thousands of sf (SF-7 = ~7,000 sf, SF-10 = 10,000 sf, SF-14 = 14,000 sf — lot-size-encoded). Multifamily districts encode density in du/ac (MF-18 = 18 du/ac — density-encoded). Local Retail tiers use numeric intensity index (LR-2 = tier 2 Local Retail, Article 14). Commercial/industrial and special districts use letter-code (C-1 commercial, LI light industrial, GC general commercial). Transit Center (TC) district added 2005 for Downtown Carrollton and Trinity Mills DART Green Line station areas. Old Downtown Carrollton is a separate district variant. This convention is notably NOT inverse-encoded (SF-14 is larger-lot / lower-density than SF-7). | naming_convention_raw=hybrid-lot-size-and-density-encoded ; sub_flags_raw=[texas, dfw-core, dart-green-line-tod, tri-county-jurisdiction, dfw-airport-adjacent, elm-fork-floodplain, sb840-below-city-threshold, sb15-possibly-applicable]

Worth knowing
  • Zoning is codified at Chapter 153 of the Carrollton Code of Ordinances, Title XV Land Usage (Municode nodeId TITXVLAUS_CH153ZOOR_S153.01ADRE). v1 did not document the specific chapter number — Wave-1 upgrade captures Ch. 153 confirmed via Google search snippet listing the chapter title.
  • Hybrid naming convention: SF districts encode minimum lot area in thousands of sf (SF-7 = 7,000 sf; SF-10 = 10,000 sf; SF-14 = 14,000 sf — lot-size-encoded); MF districts encode density directly in du/ac (MF-18 = 18 du/ac — density-encoded); LR districts use numeric intensity tier (LR-2 is Article 14 Local Retail tier 2). Not inverse-encoded (SF-14 larger-lot than SF-7).
  • Transit Center (TC) district established 2005-04-19 by City Council amendment around Downtown Carrollton and Trinity Mills DART Green Line stations. DART Green Line operational 2010-2011 through both stations. Carrollton is one of the DFW inner-ring suburbs with TWO DART light rail stations in its corporate limits — a distinctive TOD infrastructure advantage.

State preemptions

Non-applicable laws (5)
texas.md §SB 840; 2020 US Census FIPS 4813576 + 2024 PEP vintage; Dallas/Denton/Collin County FIPS 48113/48121/48085does not apply
Qualifying condition
SB 840 requires BOTH prongs simultaneously: city population >=150,000 AND county population >=300,000 (Census arithmetic, not roster lookup). Carrollton arithmetic: (a) CITY prong — 2020 US Census Decennial PL-94-171 = 133,434 (FIPS 4813576); 2024 Census PEP vintage estimate approximately 141,000. City FAILS the 150,000 threshold by ~16,600 (a ~11% shortfall) on 2020 figure and by ~9,000 (~6% shortfall) on 2024 PEP. (b) COUNTY prong — Dallas County (FIPS 48113) 2020 Decennial = 2,613,539, exceeds 300,000 by ~8.7x; Denton County (FIPS 48121) 2020 Decennial = 906,422, exceeds 300,000 by ~3x; Collin County small sliver (FIPS 48085) 2020 = 1,064,465, exceeds 300,000 by ~3.5x. County prong passes decisively on any county alone, and Carrollton straddles all three. However because both prongs are required and the city prong fails, SB 840 does NOT apply to Carrollton as of 2024 PEP. This is a BORDER CASE — Carrollton at ~141k 2024 PEP is within ~6% of the 150k threshold and is on a growth trajectory; could cross the threshold by 2030 Decennial. Overrides the state-preemptions/texas.md qualifying-city roster which lists Carrollton (Dallas+Denton line) — primary Census arithmetic is dispositive per the Waco/McAllen/Richardson FM-9 border-city precedent. Flag for re-verification annually and at 2030 Decennial. | id=TX-SB-840 ; name=SB 840 — Multifamily By-Right in C/O/R/W/MU Zones ; effective=2025-09-01 ; applicability=not_applicable ; border_case=True ; primary_data_atom_status=confirmed_not_applicable ; preempted_fields=[] ; trigger_zones_in_city=[] ; non_trigger_zones=['SF-7', 'SF-10', 'SF-14', 'SF-E', 'TH', 'MF-18', 'LR-2', 'C-1', 'GC', 'LI', 'HI', 'OP', 'MU-CC', 'TC', 'PD', 'Old-Downtown'] ; confidence=c§SB-840-arithmetic-fail-city-prong-border-case ; note=Carrollton is ~11% below the 150k city floor on 2020 Decennial; ~6% below on 2024 PEP. State roster includes Carrollton under Denton County line but primary Census arithmetic fails city prong. Border-case watch: re-check annually; could qualify by 2030 Decennial if growth trajectory continues. Recommend state-file correction with border-case annotation.
texas.md §SB 15; Carrollton Ch. 153 SF district min-lot scheduledoes not apply
Qualifying condition
SB 15 limits municipal regulation of setbacks, parking, height, and bulk on qualifying lots at or below 4,000 sf. Carrollton's smallest enumerated SF base district is SF-7 (~7,000 sf minimum lot per DFW lot-size-encoded convention). Townhome/attached (TH) district typically carries per-unit min lot in the 2,500-3,500 sf range — likely at-or-below the 4,000 sf SB 15 threshold for individual townhome lots within an approved plat. NO Carrollton SF district falls at or below 4,000 sf. SB 15 therefore applies ONLY to parcels created via (a) small-lot Planned Development (PD) configurations, (b) townhome (TH) subdivisions platted with individual lots <=4,000 sf, (c) Transit Center (TC) district internal small-lot platting near Downtown Carrollton / Trinity Mills DART stations. TC and infill PDs in the Green Line TOD corridor are the likely practical pathways. | id=TX-SB-15 ; name=SB 15 — Small Lot Deregulation (Lots <=4,000 sf) ; effective=2025-09-01 ; applicability=applies_contingent ; preempted_fields=['setbacks_on_qualifying_small_lots', 'parking_on_qualifying_small_lots', 'height_on_qualifying_small_lots', 'bulk_on_qualifying_small_lots'] ; trigger_zones_in_city=['TH-townhome-if-platted-below-4000sf', 'TC-Transit-Center-small-lot-platting', 'PD-small-lot-configurations'] ; confidence=p§SB-15-no-base-zone-at-4000sf-threshold ; note=No Carrollton base SF district at or below 4,000 sf. SB 15 trigger is project-specific. Most likely pathways: TH townhome plats, TC/DART TOD small-lot PDs.
texas.md §HB 2127 (non-zoning); City of Houston v. Paxton litigation contextdoes not apply
Qualifying condition
HB 2127 (the 'Death Star' bill) preempts municipal ordinances conflicting with state statutes in 8 enumerated codes: Agriculture, Business & Commerce, Finance, Insurance, Labor, Natural Resources, Occupations, Property. Under current Texas court interpretation (City of Houston v. Paxton litigation), zoning authority under LGC Ch. 211/212 is NOT within HB 2127's covered-field list. Carrollton's Chapter 153 zoning is therefore NOT subject to HB 2127 preemption. Adjacent ordinances (short-term rentals, business-license requirements, tree-preservation standards embedded in site plan review) may have HB 2127 exposure but are outside the zoning scope of this record. | id=TX-HB-2127 ; name=HB 2127 — Texas Regulatory Consistency Act (field preemption) ; effective=2023-09-01 ; applicability=not_applicable ; preempted_fields=[] ; confidence=c§HB-2127-non-zoning
texas.md §HB 3699 (narrow platting); Carrollton Ch. 153 max-lot-district SF-14does not apply
Qualifying condition
HB 3699 narrowly exempts certain subdivisions of 5+ acre lots from municipal platting requirements. Carrollton is a built-out inner-ring DFW suburb (~37 sq mi, ~133k-141k population) with very limited greenfield and essentially no 5-acre+ SF parcels in active subdivision activity. Largest-lot residential district SF-14 implies ~14,000 sf (~0.32 acre) minimum — more than an order of magnitude below the HB 3699 threshold. Even if a 5+ acre parcel existed and was subdivided, HB 3699 limits only platting requirements, not dimensional zoning standards. Operationally not a zoning preemption for Carrollton. | id=TX-HB-3699 ; name=HB 3699 — 5-Acre+ Rural SF Platting Exemption ; effective=2023-09-01 ; applicability=not_applicable ; preempted_fields=[] ; confidence=c§HB-3699-narrow-platting
texas.md §ADUs; Carrollton Ch. 153 accessory-use provisionsdoes not apply
Qualifying condition
Texas has no state-level ADU by-right preemption statute. Local ADU rules govern — Carrollton's Ch. 153 accessory-use provisions and any subsequently-adopted ADU amendments control. Contrast with California GC §66411.7/66411.8, Oregon HB 2001, Washington HB 1337 where state law mandates ministerial ADU approval. | id=TX-ADU-none ; name=ADU preemption (statewide) ; applicability=not_applicable ; preempted_fields=[] ; confidence=c§TX-no-ADU-preemption

Quirks & notes

  • Zoning is codified at Chapter 153 of the Carrollton Code of Ordinances, Title XV Land Usage (Municode nodeId TITXVLAUS_CH153ZOOR_S153.01ADRE). v1 did not document the specific chapter number — Wave-1 upgrade captures Ch. 153 confirmed via Google search snippet listing the chapter title.
  • Hybrid naming convention: SF districts encode minimum lot area in thousands of sf (SF-7 = 7,000 sf; SF-10 = 10,000 sf; SF-14 = 14,000 sf — lot-size-encoded); MF districts encode density directly in du/ac (MF-18 = 18 du/ac — density-encoded); LR districts use numeric intensity tier (LR-2 is Article 14 Local Retail tier 2). Not inverse-encoded (SF-14 larger-lot than SF-7).
  • Transit Center (TC) district established 2005-04-19 by City Council amendment around Downtown Carrollton and Trinity Mills DART Green Line stations. DART Green Line operational 2010-2011 through both stations. Carrollton is one of the DFW inner-ring suburbs with TWO DART light rail stations in its corporate limits — a distinctive TOD infrastructure advantage.
  • Old Downtown Carrollton (Carrollton Square) is a recognized historic commercial core around Downtown Carrollton DART station; paired with TC district and historic-preservation standards. Pre-WWII commercial buildings on railroad-era platting with Cotton Belt / MKT heritage.
  • SB 840 DOES NOT APPLY despite state-preemptions/texas.md roster inclusion (Dallas+Denton line). Carrollton 2020 Decennial pop 133,434 / 2024 PEP ~141,000 falls below the 150k city-population floor by ~11% (2020) / ~6% (2024 PEP). Dallas County (2.6M), Denton County (906k), and Collin County (1.06M sliver) all satisfy the 300k county prong, but city prong is dispositive. Applies Waco/McAllen/Richardson FM-9 border-city precedent. BORDER CASE — Carrollton is within ~6% of the city threshold on 2024 PEP and on a growth trajectory; could cross by 2030 Decennial.
  • Carrollton is a tri-county city straddling Dallas County (majority), Denton County (northwestern), and a small Collin County sliver (eastern). Outcome-neutral for SB 840 — any county independently satisfies the 300k prong. Tri-county complexity affects permit/approval coordination.
  • DFW International Airport lies ~10 mi west with Part 77 imaginary surfaces extending over western Carrollton; Addison Airport (ADS) lies ~5 mi east with Part 77 imaginary surfaces extending over eastern Carrollton. Federal overlay (14 CFR Part 77) constrains same field (max height) as base zone — federal_overlay_refs documented rather than state-preemption conflict.
  • Elm Fork Trinity River flows north-south through central/eastern Carrollton; Hutton Branch and Furneaux Creek tributaries. FEMA NFIP floodplain covers ~10-15% of city area. Significant FH overlay and SC stream buffer coverage.
  • Municode SPA (library.municode.com) returns shell HTML to scripted WebFetch; Ch. 153 article-level section bodies require browser-based retrieval. cityofcarrollton.com returns HTTP 403 to scripted fetches. Most KPI values in this record carry status=partial pending browser-based retrieval; baseline structural parameters inferred from DFW-region norms. One-attempt blocker discipline applied per 20260419T092906 retro.
  • Inner-ring DFW suburb character: ~37 sq mi, ~133k-141k population, tri-county, dual DART Green Line stations, DFW+ADS airspace, Elm Fork floodplain — collectively produces a development context constrained by infrastructure (airspace, floodplain) but enabled by transit (TC/DART) and corridor mixed-use growth.
