Classic Euclidean: Chapter 23 defines base districts + overlay regimes. No transect, no form-based core, PDs used but not dominant path. SF district numbers do NOT encode density or lot size in a simple formula (SF-1 is LARGER than SF-4) — this is a de-facto INVERSE pattern within the SF family but overall naming uses descriptive tiers; flagged as quirk.

State preemptions
TX SB 15 (2025)applies
Qualifying condition
Statewide applicability on lots <=4,000 sf. Cedar Hill's TH (Townhome) base district allows 3,000 sf min lot, creating per-parcel trigger whenever TH subdivision plats produce lots 3,000-4,000 sf. Small-lot deregulation of setbacks/parking/height/FAR preempts city regulation on those parcels.
Source
TX SB 15 statute text; Cedar Hill Ch. 23 base-district roster (TH min_lot_sf = 3,000 per v1 extract).
Effect
Waives city regulation of setbacks, parking ratio, max height, max FAR on qualifying <=4,000 sf parcels.
TX SB 2038 (2023)applies
Qualifying condition
Statewide. Cedar Hill exercises ETJ under TX Local Gov't Code ch. 42; SB 2038 allows owners in ETJ to petition for release from ETJ. Cedar Hill must honor valid petitions.
Source
TX SB 2038 statute; municipal ETJ status confirmed via Dallas Central Appraisal District and Cedar Hill subdivision regulations (Ch. 20).
Effect
Owners in Cedar Hill ETJ may petition for release; city must process.
TX HB 2127 (2023, Death Star)applies
Qualifying condition
Statewide preemption of local regulation in fields occupied by state law (labor, occupations, agriculture, etc.). Cedar Hill, like all TX home-rule cities, cannot adopt ordinances in preempted subject areas.
Source
TX HB 2127 statute; post-injunction status — enforceable as of 2026-Q1.
Effect
Invalidates any Cedar Hill ordinance in preempted fields.
TX HB 3903 (2023, STR preemption)applies
Qualifying condition
Statewide limitation on cities banning short-term rentals in residential districts. Cedar Hill's residential districts (RE/SF-1..SF-4/TH/MF) subject.
Source
TX HB 3903 statute; Cedar Hill Ch. 23 residential district roster.
Effect
City may register and tax STRs but cannot outright ban in SF districts.
Non-applicable laws (1)
TX SB 840 (2025)does_not_apply
Qualifying condition
City pop 49,618 (Census PEP 2024) < 150,000 city floor. Dallas County pop 2,606,358 (2024) >= 300,000 meets county threshold, but BOTH city and county thresholds are required. City-floor fails — law does not apply. | reason=Population below 150k city floor

Documented gaps
- Exact numerical values (height, setback, FAR, du/ac, lot coverage) for all 11 base districts remain `partial` — primary source is Municode SPA (known blocker) and a city-hosted PDF that exceeds WebFetch content-size limit. Needs DOM-capable fetcher or human review for verification.
- Exact overlay parameter values (coverage %, setback ft, height multiplier, FAR multiplier) remain `partial` for all 5 overlays.
- Chapter 23 Article-level section anchors (§-level citations) are typed at Article granularity, not § granularity, because the code was not read in this pass.
