Overview

Code type
euclidean
Naming convention
lot-size-suffix

SF-E (Estate), SF-30, SF-20, SF-15, SF-10 residential series uses lot-size suffix in thousands of sf (SF-10 = 10,000 sf minimum). Contrast with Denton's density-index pattern (R1/R3/R5/R7). AG is Agricultural; CC/NS/BP/LI follow conventional DFW commercial/industrial abbreviations.

Worth knowing
  • Chapter 98 (not 151) is the actual zoning chapter. v1 fabricated 'Chapter 151' citation — same class of error as Waco (Ch 26 to 155) and Mansfield. Municode nodeId SPBLADERE_CH98ZO confirms.
  • SB 840 does NOT apply: city 79k-86k below 150k threshold. This is a Census arithmetic check (both prongs required), not a roster lookup. Denton County at ~1.0M passes the county prong, but the city prong failure alone defeats SB 840.
  • SB 15 has no base-zone trigger: smallest SF district is SF-10 (10,000 sf), well above the 4,000-sf SB 15 threshold. SB 15 applies only to small-lot configurations platted within PDs or townhome subdivisions.

State preemptions

Non-applicable laws (5)
does not apply
Qualifying condition
SB 840 requires BOTH prongs: city population >=150,000 AND county population >=300,000 (Census arithmetic, not roster). Flower Mound: 2020 Decennial 79,135; 2024 PEP vintage estimate ~86,074 — city FAILS the 150,000 threshold by ~64,000. Denton County 2020 Decennial 906,422 / 2024 PEP estimate ~1,003,571 — county passes the 300,000 threshold. Because BOTH prongs are required and the city prong fails, SB 840 does NOT apply regardless of county population. Arithmetic check, not roster lookup.
does not apply
Qualifying condition
SB 15 limits city regulation of setbacks, parking, height, and bulk on qualifying lots at or below 4,000 sf. Flower Mound's smallest enumerated SF district is SF-10 (10,000 sf minimum lot size per division 7 of Art. III Ch. 98). No enumerated SF district at or below 4,000 sf exists in the Chapter 98 base-district list. SB 15 therefore applies ONLY to parcels created via (a) MF/townhome subdivisions platted with <=4,000-sf lots, or (b) planned developments / PDs approved with <=4,000-sf individual lot configurations. No generic SB 15 trigger zone in the base euclidean schedule.
does not apply
Qualifying condition
HB 2127 preempts municipal ordinances that conflict with state statutes in enumerated codes (Agriculture, Business & Commerce, Finance, Insurance, Labor, Natural Resources, Occupations, Property). Zoning is not within HB 2127's covered-field list under Texas courts' current interpretation (City of Houston v. Paxton litigation context). Flower Mound's Chapter 98 zoning is therefore NOT subject to HB 2127 preemption.
does not apply
Qualifying condition
HB 3699 exempts certain subdivisions of 5+ acre lots from municipal platting requirements. Flower Mound's Chapter 98 AG and SF-E districts may contain parcels at or above 5 acres; the statute narrowly limits platting-requirement application, not dimensional zoning. Does NOT affect Chapter 98 setback/height/density standards. Flagged for completeness; operationally not a zoning preemption.
does not apply
Qualifying condition
Texas has no state-level ADU by-right preemption statute. Local ADU rules (including Flower Mound's Chapter 98 accessory-dwelling provisions) govern. Contrast with California GC 66411.7/66411.8, Oregon HB 2001, Washington HB 1337.

Quirks & notes

  • Chapter 98 (not 151) is the actual zoning chapter. v1 fabricated 'Chapter 151' citation — same class of error as Waco (Ch 26 to 155) and Mansfield. Municode nodeId SPBLADERE_CH98ZO confirms.
  • SB 840 does NOT apply: city 79k-86k below 150k threshold. This is a Census arithmetic check (both prongs required), not a roster lookup. Denton County at ~1.0M passes the county prong, but the city prong failure alone defeats SB 840.
  • SB 15 has no base-zone trigger: smallest SF district is SF-10 (10,000 sf), well above the 4,000-sf SB 15 threshold. SB 15 applies only to small-lot configurations platted within PDs or townhome subdivisions.
  • Cross Timbers Conservation Development District (CTCDD) is a named Flower Mound-specific conservation overlay addressing post-oak/blackjack-oak ecosystem — unusual in DFW. Adopted via Ord. 54-22 (LDR22-0002).
  • Master Plan 2001 rural-preservation ethos persists: large-lot SF-E / SF-30 / SF-20 predominate; anti-density coalitions politically dominant; rezoning to MF effectively rare.
  • Lake Lewisville watershed drains the entire corporate area; NTMWD source-water protection constrains impervious cover in sensitive subareas.
  • DFW Airport approach corridors extend Part 77 imaginary surfaces over northeast Flower Mound (runway 17/35 approaches); height-restricted regardless of base zoning.
  • No DART rail service; zoning reflects car-dependent low-density suburban model; Lakeside Town Center (LTC) is the lone concession to mixed-use/walkable form.
  • FM 2499 and FM 1171 corridor overlays impose enhanced setbacks, shared-access requirements, and design-review standards on frontage parcels — commercial entitlement is narrower than base-zone standards alone suggest.
  • Lot-size-suffix naming (SF-10 = 10,000 sf) contrasts with Denton's density-index pattern (R1/R3/R5/R7). Promote to naming-conventions reference if not already listed.

Formulas

Definitions

setback_front
Front property line to nearest building face per Ch. 98 Art. III.
setback_side
Side property line to nearest building face.
setback_rear
