Pasadena, TX Zoning — Only Plans

Overview

Worth knowing

NO-ZONING city. Pasadena, TX has never adopted a formal zoning ordinance — one of only a handful of TX cities in this category (Houston is the most famous; Pasadena sits immediately southeast of Houston and shares the non-zoning tradition). Land-use control is via (a) Basic Subdivision Ordinance (Code of Ordinances Appendix A), (b) private deed restrictions (recorded at Harris County Clerk, enforced primarily by private parties), (c) building/fire/life-safety codes, (d) floodplain ordinance, (e) health/nuisance ordinances. The city issues a standard 'No Zoning Letter' to satisfy title/lender due diligence.
v1 PROFILE FABRICATION CORRECTED. The prior v1 profile materialized 15 zoning districts (SF-1/SF-2/SF-A/RM-1/MF-L/M/H/MH/NC/GC/AC/CBD/LI/GI/PI) and 4 overlay codes (FO/HSCIBO/PCHPOCC/EWRCO) with full dimensional standards. None of these districts or overlay codes exists in Pasadena's code of ordinances. v2 refresh empties base_districts[] and re-characterizes the 4 'overlays' as non-zoning regional/federal context, not municipal zoning overlays. This is a code-type flip (euclidean → no-zoning) and a >30% district-roster change (15 districts → 0 districts); research.md is regenerated per orchestrator rule.
POPULATION THRESHOLD BORDERLINE for SB 840. 2020 Decennial Census = 151,950 (qualifies); 2024 Census Bureau estimate = 149,615 (below threshold). Harris County ≥300,000 is easily met. Eligibility depends on which population vintage state law treats as controlling — Texas statutes typically use 'most recent federal decennial census' which favors QUALIFIES. 2030 Decennial could flip eligibility if population has continued to decline. Practical impact is limited anyway because SB 840 preempts zoning-district categories that Pasadena does not have.

Overlays

Floodplain Management (NFIP Compliance, non-zoning)

Pasadena Code of Ordinances (Flood Damage Prevention ordinance; specific chapter pending section-level retrieval)

FEMA Flood Insurance Rate Maps (FIRMs) for Harris County; Special Flood Hazard Areas (A/AE zones, 1% annual-chance floodplain) and Shaded X zones (500-year). Pasadena lies largely in the Vince Bayou / Armand Bayou / Buffalo Bayou drainage basins feeding Galveston Bay and the Houston Ship Channel; Hurricane Harvey (August 2017) inundated material portions of the city and triggered post-disaster FIRM revisions coordinated by Harris County Flood Control District (HCFCD).

base_flood_elevation_source	FEMA FIRM (effective panels per Harris County)

SUBDIV

Subdivision Regulations (plat-based land-use control, non-zoning surrogate)

SPEC

Pasadena Basic Subdivision Ordinance (Code of Ordinances Appendix A)

City corporate limits and ETJ (5-mile ETJ per TX LGC §42.021 pop-100k tier). Applies at time of plat approval/re-plat; runs with the land thereafter.

mechanism	plat approval + private deed restrictions recorded at Harris County Clerk
minimum_lot_size_set_by	subdivision plat (varies by subdivision; no citywide district floor)
setbacks_set_by	subdivision plat + recorded covenants (not city zoning)
use_restrictions_set_by	private deed restrictions (city does not maintain deed records; Harris County Clerk maintains)

HSCIBO_CONTEXT

Houston Ship Channel / Industrial Buffer (NOT a zoning overlay — regional/federal context)

SPEC

Not a Pasadena zoning overlay (no zoning exists). Industrial/port activity along the Houston Ship Channel is regulated by the Port of Houston Authority, USCG navigable-waters jurisdiction, EPA/TCEQ air-quality permitting, and federal facility siting rules; within the City of Pasadena, only non-zoning life-safety and nuisance ordinances apply.

Houston Ship Channel runs along the northern boundary of Pasadena (Buffalo Bayou / San Jacinto River confluence). Adjacent land is predominantly owned/operated by refineries, chemical terminals, and port facilities.

status	not_captured
not_captured_reason	No municipal overlay ordinance identified; industrial/port regulation is external to city zoning because city has no zoning.
federal_state_external_refs	Port of Houston Authority jurisdiction; USCG 33 CFR navigable waters; EPA/TCEQ Title V air permits (Pasadena refineries); OSHA PSM / EPA RMP for chemical facilities

PCHPOCC_CONTEXT

Petrochemical Corridor / Hazard Proximity (NOT a zoning overlay)

COR

Not a Pasadena zoning overlay. Petrochemical facility siting is regulated by TCEQ air permits, EPA RMP/RCRA, OSHA PSM, and federal PHMSA pipeline rules. The 1989 Phillips 66 Pasadena disaster and subsequent industrial incidents drive facility-level emergency planning (LEPC coordination) rather than zoning-overlay regulation.

Pasadena hosts a dense concentration of petrochemical facilities along the ship channel (Shell Deer Park adjacent, LyondellBasell, Chevron Phillips, etc.). Texas City refinery corridor lies ~10–20 mi south.

status	not_captured
not_captured_reason	No municipal petrochemical overlay identified; regulation is federal (EPA/OSHA/PHMSA) and state (TCEQ).
emergency_planning_framework	Harris County LEPC, TCEQ Emission Events reporting, EPA RMP worst-case release plans

EWRCO_CONTEXT

Environmental / Wetland / Riparian Corridor (NOT a zoning overlay)

COR

Not a Pasadena zoning overlay. Wetland/riparian protection is provided by CWA §404 (USACE), TPWD state stream standards, TCEQ §401 water quality certification, and HCFCD regional drainage criteria.

Vince Bayou, Armand Bayou (Pasadena Park Nature Area), and tidal wetlands along the ship channel. Armand Bayou Nature Center is a Harris County-administered preserve, not a city zoning district.

status	not_captured
not_captured_reason	No municipal environmental overlay identified; wetland/riparian regulation is federal (USACE §404) + state (TCEQ/TPWD) + regional (HCFCD).
hcfcd_coordination_criteria	HCFCD regional detention + impervious cover + channel-modification criteria apply on cross-jurisdictional projects.

HIST

Historic / Heritage Overlay

None identified as a zoning overlay.

n/a

status	not_found
search_performed	Searched pasadenatx.gov and Municode index for historic district / heritage preservation ordinance; no zoning-overlay historic district identified. Pasadena has some individually-listed NRHP sites but no municipal historic overlay district.

TOD

TOD / Transit Overlay

TOD

None.

n/a

status	not_found
search_performed	No METRORail or commuter-rail station in Pasadena city limits; METRO park-and-ride and local bus service only. No TOD overlay possible without fixed-guideway transit.

AIRPORT

Airport / Airspace Overlay

Federal FAA Part 77 imaginary surfaces apply to Ellington Field (KEFD) ~6 mi south, Hobby Airport (KHOU) ~5 mi west, and William P. Hobby traffic corridors. Not codified as a Pasadena zoning overlay.

Ellington Field KEFD ~6 mi S (civil/military joint); William P. Hobby KHOU ~5 mi W (civil); Part 77 horizontal and conical surfaces extend over portions of Pasadena. Ellington hosts TX Air National Guard + NASA + US Coast Guard aviation; limited AICUZ-style overlay applicable.

federal_reference	FAA 14 CFR Part 77 obstacle evaluation; FAA Form 7460-1 filing required for structures exceeding surfaces.
ellington_aicuz_applicability	partial — Ellington has DoD joint-use status; AICUZ study may identify APZ/noise contours extending toward Pasadena, but not codified in Pasadena ordinances.
municipal_overlay	not_found

Downtown / CBD Overlay

None.

n/a

status	not_found
search_performed	No downtown zoning overlay possible because city has no zoning; downtown/Old Pasadena revitalization is pursued via CDBG/HUD and TIRZ mechanisms, not zoning.

CORR

Corridor / Highway Overlay

COR

None as a zoning overlay.

SH 225 (La Porte Fwy — petrochemical corridor), Beltway 8, SH 146, and Spencer Hwy traverse Pasadena; TxDOT access management applies but no city zoning overlay exists.

status	not_found
search_performed	No corridor zoning overlay identified; TxDOT access management + driveway permits govern frontage on state highways.

Affordable Housing Bonus

None.

n/a

status	not_found
search_performed	Density bonuses are impossible without a base-density regime. Affordable housing support in Pasadena is via CDBG/HOME funding and HUD programs, not a zoning bonus overlay.

AICUZ

Military / AICUZ Overlay

MIL

Ellington Field hosts Texas Air National Guard (147th Attack Wing), US Coast Guard, and NASA aviation. AICUZ study applicable; no Pasadena municipal AICUZ overlay ordinance identified.

Ellington Field (KEFD) ~6 mi S of Pasadena. APZs and noise contours may extend toward southwestern Pasadena.

federal_reference	DoD AICUZ program; JBSA/Ellington joint-use status
municipal_overlay	not_found
noise_contours_DNL_65_70	under_review — Ellington AICUZ noise contours may extend into Pasadena city limits but not codified locally.

State preemptions

TX SB 15applies

Qualifying condition

Lot-size threshold (≤4,000 sf); statewide applicability without population precondition. Pasadena as a municipality with regulatory authority over platting and subdivision is within scope to the extent it regulates setbacks, parking, height, or bulk on qualifying small lots. Because Pasadena has no zoning, the primary channel of SB 15 preemption is the Basic Subdivision Ordinance + deed-restriction enforcement posture. | year=2025 ; what_is_confirmed=SB 15 is statewide (2025); applies to Pasadena on its face. ; what_is_missing=The Basic Subdivision Ordinance text was not retrieved in this pass; specific setback/frontage minima that SB 15 would preempt on ≤4,000 sf lots have not been catalogued.

Effect

Limits city regulation of setbacks, parking, height, and bulk on lots ≤4,000 sf. In Pasadena's no-zoning context, principal effect is against Basic Subdivision Ordinance minimum-lot-size, minimum-frontage, and setback prescriptions.

TX HB 2127 (Texas Regulatory Consistency Act / 'Death Star' bill)applies

Qualifying condition

Statewide; applies to all Texas home-rule cities including Pasadena. | year=2023

Effect

Preempts local regulation in agriculture, business/commerce, finance, insurance, labor, natural resources, occupations, and property fields where state law occupies the field. Narrows any Pasadena ordinance adjacent to land use that reaches into business-operations or property-rights territory.

TX SB 2038applies

Qualifying condition

Pasadena has ETJ jurisdiction per TX LGC §42.021 (pop-100k tier = 5 mi ETJ under prior law; reduced post-2023 for some tiers). SB 2038 applies statewide. | year=2023

Effect

Property owners may petition for release from Pasadena ETJ; limits ETJ-based regulation including any subdivision oversight of unincorporated adjacent parcels.

Non-applicable laws (2)

TX SB 840under_review

Qualifying condition

City population: 2020 Decennial Census = 151,950 (qualifies: ≥150,000); 2024 Census Bureau estimate = 149,615 (does not qualify). County population: Harris County ~4,835,125 (2024 est) ≥ 300,000 (qualifies). SB 840 preemption applicability thus turns on which population vintage the state treats as binding. Texas statute generally references the 'most recent federal decennial census' which would be 2020 = 151,950 → QUALIFIES. However, the threshold predicate in state-overlays/texas.json uses `city.population` attribute which for this record is the 2024 est = 149,615, which would not qualify. Operational posture: treat as APPLIES based on 2020 Decennial, with explicit flag that 2024 estimate falls below threshold and 2030 Decennial could flip eligibility. | year=2025 ; what_is_confirmed=Harris County ≥ 300,000 threshold (easily met, ~4.8M). 2020 Decennial city population (151,950) exceeds 150,000. ; what_is_missing=Texas Attorney General or appellate guidance on whether SB 840's 'population' predicate uses the most recent decennial (2020) or most recent annual estimate (2024) when they straddle the threshold. Without that guidance, this record flags borderline. ; effect_if_applies=Would require ministerial multifamily-by-right approval on commercial/office/retail/warehouse/mixed-use parcels at ≥36 du/ac, ≥45 ft height, ≤25 ft setback, ≤1 parking space per unit. CRITICAL NUANCE for Pasadena: SB 840 operates against a zoning baseline (it preempts categories of zoning districts). In a no-zoning city, the preemption mechanism is structurally inapplicable — there are no commercial / office / retail / warehouse / mixed-use districts to upgrade. Effect reduces to ensuring that any non-zoning ordinances (deed restriction enforcement, subdivision rules, nuisance) cannot be used to functionally replicate a commercial-use-only regime that excludes MF. Practical effect is therefore very limited in Pasadena. ; highest_local_mf_density_reference=Not applicable — no city-adopted MF density standard exists in Pasadena. ; highest_local_height_reference=Not applicable — no city-adopted district height standard exists in Pasadena. | applies_raw=borderline

TX STR Preemption frameworkunder_review

Qualifying condition

Statewide STR preemption doctrine evolving through case law and proposed legislation; Pasadena's non-zoning posture plus limited STR regulatory activity means practical preemption impact is minimal. | year=2023-pending ; what_is_confirmed=Statewide preemption trajectory limits city ability to ban STR outright. ; what_is_missing=Pasadena's specific STR ordinance text (if any) was not retrieved; practical effect in a no-zoning city is near-zero because there is no residential-district STR prohibition to preempt. | applies_raw=partial

Effect

Limits any Pasadena ordinance that would restrict STR in residential contexts.

Quirks & notes

NO-ZONING city. Pasadena, TX has never adopted a formal zoning ordinance — one of only a handful of TX cities in this category (Houston is the most famous; Pasadena sits immediately southeast of Houston and shares the non-zoning tradition). Land-use control is via (a) Basic Subdivision Ordinance (Code of Ordinances Appendix A), (b) private deed restrictions (recorded at Harris County Clerk, enforced primarily by private parties), (c) building/fire/life-safety codes, (d) floodplain ordinance, (e) health/nuisance ordinances. The city issues a standard 'No Zoning Letter' to satisfy title/lender due diligence.
v1 PROFILE FABRICATION CORRECTED. The prior v1 profile materialized 15 zoning districts (SF-1/SF-2/SF-A/RM-1/MF-L/M/H/MH/NC/GC/AC/CBD/LI/GI/PI) and 4 overlay codes (FO/HSCIBO/PCHPOCC/EWRCO) with full dimensional standards. None of these districts or overlay codes exists in Pasadena's code of ordinances. v2 refresh empties base_districts[] and re-characterizes the 4 'overlays' as non-zoning regional/federal context, not municipal zoning overlays. This is a code-type flip (euclidean → no-zoning) and a >30% district-roster change (15 districts → 0 districts); research.md is regenerated per orchestrator rule.
POPULATION THRESHOLD BORDERLINE for SB 840. 2020 Decennial Census = 151,950 (qualifies); 2024 Census Bureau estimate = 149,615 (below threshold). Harris County ≥300,000 is easily met. Eligibility depends on which population vintage state law treats as controlling — Texas statutes typically use 'most recent federal decennial census' which favors QUALIFIES. 2030 Decennial could flip eligibility if population has continued to decline. Practical impact is limited anyway because SB 840 preempts zoning-district categories that Pasadena does not have.
HOUSTON SHIP CHANNEL FRONTAGE. Pasadena's northern edge sits along the Houston Ship Channel — the densest petrochemical/industrial concentration in North America. Without zoning, incompatibility between residential neighborhoods and refinery/chemical operations is mediated by (a) private ownership patterns, (b) EPA/OSHA/TCEQ facility-level permits, (c) building codes, and (d) post-incident civil litigation. The 1989 Phillips 66 Pasadena explosion (23 killed) and subsequent incidents have shaped emergency-planning infrastructure (Harris County LEPC) but have NOT produced a zoning-overlay response because no zoning scheme exists to modify.
FLOODPLAIN REGIME POST-HARVEY. Pasadena was severely impacted by Hurricane Harvey (August 2017). Post-Harvey, Harris County Flood Control District tightened regional detention, impervious-cover, and freeboard standards; Pasadena's Flood Damage Prevention ordinance is expected to coordinate with HCFCD regional criteria. Specific Pasadena freeboard value (likely 1–2 ft above BFE, consistent with HCFCD practice) was not captured in this retrieval (Municode SPA-blocked).
DEED RESTRICTION ENFORCEMENT is the de facto zoning mechanism. Private covenants recorded at the Harris County Clerk's office run with the land and dictate permitted uses, setbacks, architectural standards, and frontage in most developed subdivisions. Enforcement is primarily private (HOA, neighbor-vs-neighbor civil action); the city's role is limited. TX Property Code provides the statutory framework for deed-restriction enforcement. This creates a patchwork land-use regime that is parcel-specific rather than district-specific — materially different from any zoned city.
ELLINGTON FIELD PROXIMITY. Ellington Field (KEFD) lies ~6 mi south of Pasadena and is a joint civil/military facility hosting the Texas Air National Guard 147th Attack Wing (F-16 / MQ-9), NASA aviation operations, and US Coast Guard aviation. AICUZ noise contours and Part 77 surfaces may extend into southern Pasadena. Federal overlay only — no municipal AICUZ ordinance because no zoning.
SB 840 STRUCTURAL INAPPLICABILITY NUANCE. Even if Pasadena's population qualifies, SB 840's mechanism is to upgrade entitlements in specific zoning district categories (com/office/retail/warehouse/mu) to allow MF-by-right. In a no-zoning city, those categories do not exist as ordinance constructs — every parcel is functionally 'no zoning' by default. The preemption collapses to a narrower anti-evasion rule: the city cannot use non-zoning tools (subdivision regs, deed-restriction selective enforcement, nuisance) to replicate a commercial-only regime that excludes MF. Real-world impact is very limited relative to fully-zoned peer cities.

Capacity calculations

note: Standard capacity formulas (max_footprint_sf, max_gfa_sf, max_units_from_density) are NOT derivable from city-adopted district standards in Pasadena because no zoning districts exist. Project-specific capacity is governed by (a) platted subdivision minimums, (b) recorded deed restrictions specific to the subdivision, (c) building/fire code occupancy limits, and (d) floodplain elevation requirements where applicable.

City of Pasadena Code of Ordinances (non-zoning; land-use regulation via deed restrictions + non-zoning ordinances)

city-hosted · n/a (no zoning chapter adopted) · Municode current supplement · retrieved 2026-04-19

City-hosted page (pasadenatx.gov/287/Zoning) is the authoritative statement on zoning status. Official language: 'The City of Pasadena is a non-zoned municipality.' Supporting 'No Zoning Letter' PDF issued by the Planning Department confirms status for title/insurance purposes. Municode mirror of the Code of Ordinances exists (library.municode.com/tx/pasadena) but is JS-rendered SPA — listed here as secondary reference; no /zoning chapter is present. v1 profile fabricated a 'Title 24 — Zoning' chapter that does not exist in Pasadena code. This v2 refresh corrects the code-type classification from euclidean to no-zoning.
