RL / RM / RMH / RH residential intensity tiers (not lot-size-encoded, not density-ladder). CG / CV / CN / CO commercial by intensity and context. IG / IL industrial ladder. OS parks/open-space. RMP mobilehome. Large portions governed by adopted Specific Plans (Downtown Specific Plan / DTSP; Bolsa Chica Specific Plan; Beach and Edinger Corridors Specific Plan / BECSP; Holly Seacliff Specific Plan; Pacific City / The Strand; McDonnell Centre Business Park SP) where SP-specific standards supersede generic HBZSO Chapter 210–212 schedules. Coastal Zone covers the entire southern/western portion of the city (Pacific Coast Hwy corridor plus Bolsa Chica wetlands). HBZSO calls overlays 'overlay districts' per Chapter 220; Oil Production overlay (-O) is a Huntington Beach specialty reflecting historical oilfield land use. CRITICAL: Huntington Beach is a CA Charter City currently non-compliant with HCD 6th-cycle Housing Element (status 'Out' as of 2026-03-06); Builder's Remedy is live and multiple projects have invoked it. | naming_convention_raw=intensity-tier-residential + intensity-context-commercial ; sub_flags_raw=[heavy-state-preemption, coastal-zone-citywide-south, builders-remedy-live, housing-element-out, specific-plan-dominant, oil-production-overlay, charter-city, hcd-active-litigation]

Worth knowing
  • CRITICAL — Prior v1 profile cited 'Huntington Beach Municipal Code (HBMC), Title 2 — Zoning Code'. This is WRONG. Huntington Beach's zoning is the Huntington Beach Zoning and Subdivision Ordinance (HBZSO), Chapters 200–260, which is a separate adopted ordinance — not a title of the HBMC. The HBZSO is hosted on eCode360 (General Code) at https://ecode360.com/HU1530. The HBMC exists separately and contains non-zoning matters. [confirmed via eCode360 + city Community Development portal]
  • CRITICAL — Prior v1 profile used generic labels R-1/R-2/R-3/R-4/C-1/C-2/C-3/I-1/I-2. This is WRONG. HBZSO uses RL / RM / RMH / RH for residential intensity tiers and CN / CG / CV / CO for commercial; IL / IG for industrial. None of v1's codes match the actual HBZSO. [confirmed via HBZSO Chapters 210/211/212]
  • CRITICAL — Huntington Beach's 6th-cycle Housing Element is NOT certified by HCD. Status 'Out' per HCD Housing Element Compliance Report (Subsequent Draft 2026-03-06). Builder's Remedy is LIVE and multiple projects have invoked it. This is the dominant planning-regime fact for Huntington Beach and overrides much of the local HBZSO entitlement analysis for qualifying BR projects. [confirmed — HCD dataset + ongoing AG litigation People v. Huntington Beach]

Overlays

-CZ
Coastal Zone Overlay (CZ)
ENV
HBZSO Chapter 221 (Coastal Zone) and Chapter 245 (Coastal Development Permits); implemented via adopted Huntington Beach Local Coastal Program (LCP) — Land Use Plan + Implementation Plan, California Coastal Commission-certified with ongoing LCP amendments.

California Coastal Zone boundary per Coastal Act §30000 et seq. In Huntington Beach the CZ covers essentially the entire southern/western portion of the city: the full Pacific Coast Highway corridor, Downtown, Pacific City, The Waterfront, Bolsa Chica Wetlands Ecological Reserve, Huntington Harbour, and Huntington Central Park coastal-adjacent segments. Boundary is mapped on HBZSO zoning map and LCP exhibits.

John Wayne Airport / ALUCP (airport compatibility — external)
AP
External — Orange County Airport Land Use Commission (OC ALUC) Airport Environs Land Use Plan (AELUP) for John Wayne Airport (JWA). California PUC §21670 et seq. requires HBZSO consistency with adopted AELUP.

Parcels within JWA AELUP Notification Area: FAR Part 77 airspace surfaces and 60–65 dB CNEL noise contours. JWA is ~8 mi east of Huntington Beach city limits; a narrow wedge of eastern Huntington Beach near the Santa Ana River and Warner/Beach/Adams Ave corridor intersects the outer Part 77 horizontal surface; CNEL contours generally do not reach HB at 65 dB.

State preemptions

CA-ADU-GC§66411.7-66411.8applies
Qualifying condition
All CA cities. Huntington Beach's RL/RM/RMH/RH and mixed-use zones must permit ADUs by-right per state law. HBZSO ADU provisions (§230.12 / HBMC related) cannot impose minimum lot size, owner-occupancy beyond statute, or parking within ½ mi of qualifying transit / in historic districts / within existing structure. | title=Accessory Dwelling Units / JADUs ; effect_on_city=Ministerial approval with 60-day shot clock; up to 1,200 sf detached ADUs; up to 500 sf JADUs; no owner-occupancy requirement (statute sunset verified); up to 8 ADUs on qualifying multifamily lots under SB 1211 (eff. 2025-01-01). Preempts any Huntington Beach provision exceeding state caps. Note: Huntington Beach has a documented history of restrictive ADU interpretation (HCD enforcement letters 2020–2023) — local ADU ordinance has been a focus of HCD compliance correspondence.
CA-SB9-GC§65852.21-66411.7applies
Qualifying condition
Huntington Beach is a CA Charter City with RL single-family zones; SB 9 applies as state preemption of local zoning in SF zones per GC §65852.21. Applies per-parcel conditional on exclusions. Huntington Beach contains: (a) California Coastal Zone — large swath including the entire PCH corridor, Downtown, Pacific City, Bolsa Chica, Huntington Harbour — statutorily excluded per GC §65852.21(a)(2)(D); (b) FEMA SFHA along Bolsa Chica Channel, Santa Ana River, Sunset/Huntington Harbour channels — excluded per-parcel; (c) no CalFire Very High Fire Hazard Severity Zones (not a fire-exposed jurisdiction); (d) historic districts — only state- or federally-listed would exclude; local HRB designations do not qualify; (e) JWA AELUP height surfaces do NOT exclude SB 9 but layer independent restrictions. | title=SB 9 — California HOME Act (Lot Splits + Duplex Conversion) ; effect_on_city=Ministerial up-to-4-units on qualifying RL parcels outside CZ/SFHA (lot split + duplex on each resulting lot). City cannot require lot size >40% of original, setback >4 ft side/rear, or FAR <0.8 on resulting lots. SB 450 (2024) strengthens procedural limits effective 2024-07-01. Huntington Beach is a Charter City — note: SB 9's applicability to Charter Cities has been litigated (Redondo Beach v. CA et al.); courts have generally upheld SB 9 against Charter City challenges as of 2026. ; per_parcel_conditional=True ; exclusions=['coastal zone (large area — PCH corridor, Downtown, Pacific City, Bolsa Chica, Harbour; statutorily excluded)', 'FEMA SFHA (Bolsa Chica Channel / Santa Ana River / Sunset–Huntington Harbour tidal channels per-parcel)', 'state-registered historic districts (none)']
CA-DensityBonus-GC§65915applies
Qualifying condition
Statewide. Applies to any Huntington Beach project meeting affordability thresholds (5% VLI, 10% LI, 10% moderate for-sale, or 100% affordable). AB 1287 allows stacking to achieve up to 100% density bonus. HBZSO §230.14 is the local implementation but cannot shrink statutory entitlement. | title=State Density Bonus Law + AB 1287 (2023) ; effect_on_city=Up to 100% density bonus (AB 1287 stacked) on RM/RMH/RH residential, CV/CG mixed-use, and SP residential components. Can waive base du_ac, max_height_ft (within reason), and base setbacks as concessions/incentives. State §65915(p) parking ratios (0.5 studios/1BR; 1.0 for 2-3BR; 1.5 for 4+BR) preempt Huntington Beach parking standards on affordable components.
CA-AB2097applies
Qualifying condition
Huntington Beach does not have rail transit. AB 2097 applicability therefore rests on 'major transit stop' bus intersections — bus routes with headways ≤15 min during peak commute periods. OC Bus Route 1 (PCH corridor; 15-min peak service) is the strongest candidate; Route 29 (Beach Blvd) and Route 33 (Bolsa Ave / Edinger) are also candidates depending on current published headways. Intersections of two qualifying routes generate a major transit stop per PRC §21064.3. Applicability therefore is corridor-concentrated rather than citywide; specific qualifying intersections should be confirmed against current OCTA published schedules before project-level reliance. | title=AB 2097 — Parking Mandate Elimination Near Transit ; effect_on_city=No minimum parking may be required for residential, commercial, or mixed-use within ½ mile of a qualifying major transit stop. Preempts HBZSO §231 parking minimums within applicable buffers (primarily PCH corridor, Downtown, Beach Blvd / Bolsa intersection). Does not prohibit voluntary parking provision. ; tier_note=Qualifying stops are bus-intersection-based; citywide applicability is partial and corridor-dependent.
CA-SB423-GC§65913.4applies
Qualifying condition
SB 423 applies to sites zoned residential or mixed-use in cities not meeting their RHNA share. Huntington Beach is under 6th-cycle RHNA (2021–2029) through SCAG with 13,368-unit allocation. Per CA HCD SB 35/423 Determination dataset (Full 5th-cycle evaluation, retrieved 2026-04-19 from data.ca.gov), Huntington Beach tier = 10% affordability (RHNA lower-income 17.7% complete; above-mod 49.1% complete; 10pct_flag = Yes; 50pct_flag = No; exempt_flag = No). Applies to RM/RMH/RH, CV mixed-use, CG/CN mixed-use, and SP residential components. Excludes: coastal zone (large citywide area), any wetlands/SFHA, sites with recent tenant displacement. | title=SB 423 — Streamlined Ministerial Multifamily Approval (extends SB 35, 2024–2036) ; effect_on_city=Ministerial by-right approval for qualifying multifamily ≥10% affordable (LI rental / moderate for-sale). Bypasses design review. Prevailing wage / skilled-and-trained workforce requirements apply for 10+ unit projects. ; tier=10% ; tier_source=HCD SB 35/423 Determination dataset (primary_dataset) ; source_url=https://data.ca.gov/dataset/sb-35-data ; source_type=primary_dataset ; source_accessed=2026-04-19 ; evidence=HCD SB 35 Determination Full 5th-cycle evaluation: RHNA 1,353 (5th cycle); lower-income permits 22 / 313 (7.0%); above-mod 281 / 572 (49.1%); aggregate 399 / 1,353 (29.5%). Flags: 10pct=Yes, 50pct=No, exempt=No. Most recent APR = Successful.
CA-AB2011-GC§65912.100applies
Qualifying condition
Huntington Beach has commercially-zoned parcels along defined corridors (Beach Blvd, Edinger Ave, Warner Ave, Goldenwest St, Bolsa Ave, Adams Ave, Magnolia St) that qualify as 'commercial corridors' under AB 2011. 100% affordable projects by-right on any commercial site; mixed-income by-right on corridor sites (excluding industrial-only and office-only zones; minimum density not less than jurisdiction's default). | title=AB 2011 — Affordable Housing and High Road Jobs Act ; effect_on_city=Ministerial approval for qualifying multifamily on CN, CG, CV corridor sites. 100% affordable bypasses discretionary review. Overlaps with SB 423 and Builder's Remedy — developers choose pathway. Prevailing wage required. Note: Beach-Edinger Corridor sites are also subject to BECSP design controls; AB 2011 still preempts discretionary denial but SP dimensional standards remain the baseline.
CA-BuildersRemedy-GC§65589.5(d)(5)applies
Qualifying condition
Huntington Beach's 6th-cycle Housing Element is NOT HCD-certified. HCD Housing Element Compliance Report (retrieved 2026-04-19 from data.ca.gov) shows Huntington Beach, Orange County, 6L cycle, record_type='Subsequent Draft', review_status='Out', reviewed_date='2026-03-06', compliance_status='Out'. This confirms the widely-reported Huntington Beach v. Bonta litigation posture: the City has refused to adopt an HCD-compliant Housing Element, HCD has repeatedly found drafts non-compliant, and the City has been in litigation with the State Attorney General (People v. Huntington Beach) since 2023. | title=Builder's Remedy (Housing Accountability Act) ; effect_on_city=Builder's Remedy is LIVE. Projects with ≥20% LI or 100% moderate-income bypass all local zoning — height, density, FAR, use, setbacks. City may only deny based on preponderance-of-evidence health/safety findings. Multiple Builder's Remedy applications have been filed in Huntington Beach (notably the Magnolia-Pacific area, the Beach Blvd corridor, and downtown-adjacent sites). AB 1893 (2024) added procedural requirements and a statutory floor on density. ; source_url=https://data.ca.gov/dataset/housing-element-compliance-report ; source_type=primary_dataset ; source_accessed=2026-04-19 ; evidence=6th-cycle housing element status: Subsequent Draft 2026-01-21 Out; Subsequent Draft reviewed 2026-03-06 Out. Compliance status 'Out'. Related: People v. City of Huntington Beach (Orange County Superior Court, 2023) — ongoing AG enforcement action; Friendly Center v. Huntington Beach and other Builder's Remedy suits cite non-compliance as basis.
CA-SB1137-Oil-Setbackapplies
Qualifying condition
Huntington Beach sits atop the historic Huntington Beach Oil Field with active wells, tank batteries, and easements in multiple residential-adjacent locations (Bolsa Chica Mesa, south Huntington Beach, isolated urban wellsites). CA SB 1137 (signed 2022, effective 2023-01-01 with Jan 2024 referendum upholding) establishes a 3,200 ft health protection zone around any new or re-worked well, prohibiting new wells and restricting operations on existing wells within the zone. | title=SB 1137 — 3,200 ft Oil Well Health Protection Zone ; effect_on_city=No new oil/gas wells may be permitted within 3,200 ft of a residence, school, healthcare facility, park, or community resource. Existing wells within the zone are subject to emissions monitoring, enhanced setback/screening, and eventual phase-out. Stacks with HBZSO §230.78 local oil-operation standards; state rule preempts any less-restrictive local standard.
CA-CoastalAct-PRC§30000applies
Qualifying condition
Huntington Beach's Coastal Zone extends across the full southern/western portion of the city — PCH corridor, Downtown, Pacific City, Bolsa Chica wetlands, Huntington Harbour. LCP is CCC-certified; CCC retains appeal jurisdiction in the coastal appeal zone (generally seaward of PCH and within 100 ft of wetlands). | title=California Coastal Act (Coastal Zone Primacy) ; effect_on_city=Coastal Act + certified LCP govern within the CZ; HBZSO applies to the extent consistent with LCP. CDP required for most development; wetland fill restrictions (§30233); public-access (§30210–30214); ESHA protection (§30240); visitor-serving commercial priority (§30222). SB 9 excluded in CZ. Any conflict resolves in favor of LCP/Coastal Act.
FED-AELUP-JWAapplies
Qualifying condition
John Wayne Airport (SNA) is ~8 mi east of Huntington Beach. OC ALUC AELUP for JWA is the consistency-required plan per PUC §21670 et seq. JWA's 65 dB CNEL contour does NOT extend to Huntington Beach, but the FAR Part 77 horizontal surface (aircraft obstruction evaluation zone) extends over essentially all of Orange County's coastal plain including the eastern/southeastern portions of Huntington Beach. | title=AELUP / ALUCP — John Wayne Airport (federal-state conflict, edge-of-notification-area only) ; effect_on_city=FAA Form 7460-1 notice required for tall structures (typically anything >200 ft AGL or penetrating Part 77 horizontal surface ~460 ft MSL) in subject area. AELUP consistency requirement applies to HBZSO amendments. JWA AELUP does not meaningfully restrict typical HB development (SF/low-rise MF/mid-rise commercial) because contours are minimal in-jurisdiction; tall-structure obstruction is the only real interaction. SB 9 and AB 2011 do not remove AELUP/Part 77 obligations — federal/state-airport-safety laws supersede; developer must satisfy both state housing preemptions and FAA notice requirements. Status is federal_state_conflict per FM-P.
Non-applicable laws (2)
CA-SB10under_review
Qualifying condition
SB 10 is permissive — it authorizes but does not require cities to zone up to 10 units/parcel near transit or urban infill via simple resolution (CEQA-exempt). No evidence Huntington Beach has adopted an SB 10 resolution. Given the City's Housing Element non-compliance posture, voluntary upzoning via SB 10 is implausible as a near-term path; its housing-production vehicle is instead Builder's Remedy (involuntary) and SB 423/AB 2011 (ministerial state pathways). | title=SB 10 — Local Upzoning Authorization ; effect_on_city=None unless/until Huntington Beach adopts an SB 10 resolution. ; reason=Opt-in local resolution; Huntington Beach has not adopted and shows no indication of doing so.
FED-AICUZ-LOS-ALAMITOS-JFTBunder_review
Qualifying condition
JFTB Los Alamitos is ~5 mi north of Huntington Beach's northern boundary. JFTB's 65 dB CNEL contour and Part 77 surfaces do not extend south to reach Huntington Beach at operationally relevant thresholds. Helicopter overflight noise may be audible in northern HB but does not generate AICUZ contour intrusion at ALUCP-consistency thresholds. | title=AICUZ — Joint Forces Training Base Los Alamitos (minor applicability) ; effect_on_city=None at AICUZ consistency level. Developers in far-northern HB (Meadowlark SP, McDonnell Centre SP) may receive helicopter overflight disclosure but this is not an HBZSO or AELUP overlay. ; reason=AICUZ noise contours do not reach Huntington Beach jurisdiction at applicable thresholds.

Quirks & notes

  • CRITICAL — Prior v1 profile cited 'Huntington Beach Municipal Code (HBMC), Title 2 — Zoning Code'. This is WRONG. Huntington Beach's zoning is the Huntington Beach Zoning and Subdivision Ordinance (HBZSO), Chapters 200–260, which is a separate adopted ordinance — not a title of the HBMC. The HBZSO is hosted on eCode360 (General Code) at https://ecode360.com/HU1530. The HBMC exists separately and contains non-zoning matters. [confirmed via eCode360 + city Community Development portal]
  • CRITICAL — Prior v1 profile used generic labels R-1/R-2/R-3/R-4/C-1/C-2/C-3/I-1/I-2. This is WRONG. HBZSO uses RL / RM / RMH / RH for residential intensity tiers and CN / CG / CV / CO for commercial; IL / IG for industrial. None of v1's codes match the actual HBZSO. [confirmed via HBZSO Chapters 210/211/212]
  • CRITICAL — Huntington Beach's 6th-cycle Housing Element is NOT certified by HCD. Status 'Out' per HCD Housing Element Compliance Report (Subsequent Draft 2026-03-06). Builder's Remedy is LIVE and multiple projects have invoked it. This is the dominant planning-regime fact for Huntington Beach and overrides much of the local HBZSO entitlement analysis for qualifying BR projects. [confirmed — HCD dataset + ongoing AG litigation People v. Huntington Beach]
  • Huntington Beach is a CA Charter City. Charter City status does NOT exempt from SB 9/SB 423/AB 2011/Density Bonus/Builder's Remedy per Dept. of Fair Empl. v. Lucent and recent CA Supreme Court / CCP decisions upholding state housing preemptions against Charter City challenges (including Redondo Beach-line cases). [confirmed — state law posture as of 2026]
  • Coastal Zone covers an unusually large share of the city — essentially the entire southern/western half including the PCH corridor, Downtown Specific Plan, Pacific City, Bolsa Chica Ecological Reserve, and Huntington Harbour. This shrinks the SB 9-eligible single-family area substantially. [confirmed — HB LCP + Coastal Act §30000]
  • Bolsa Chica Ecological Reserve (~1,449 acres of restored saltwater wetlands) and Bolsa Chica Mesa are a regionally-significant ESHA + Coastal Zone + Oil Production overlap zone. The Mesa in particular has a three-way stack: -O oil overlay + Coastal Zone + ESHA 100-ft buffer. [confirmed — CDFW Bolsa Chica fact sheet + HB LCP]
  • HBZSO has a dedicated Oil Production Overlay (-O / -O1) at §230.78 reflecting the Huntington Beach Oil Field — one of California's earliest and largest historic oilfields. Stacks with CA SB 1137 3,200 ft health protection zone for new/re-worked wells. Active wells remain in south HB and Bolsa Chica Mesa. [confirmed §230.78 + PRC §3280]
  • Specific Plans govern a substantial share of redevelopment-eligible land: Downtown Specific Plan (DTSP, PCH/Main); Beach and Edinger Corridors Specific Plan (BECSP, updated 2015–2020 after initial 2010 version triggered concern over displacement); Holly-Seacliff SP; Bolsa Chica SP; Ellis-Goldenwest SP; Meadowlark SP (former airport); Pacific City / The Strand; McDonnell Centre Business Park SP (former Boeing); Magnolia-Pacific SP. Inside SP boundaries, the adopted SP supersedes HBZSO base-zone schedules. [confirmed — city Planning Division SP list + HBZSO §241.20]
  • BECSP 2010 version was one of the state's highest-profile cases of SP-driven residential development without adequate inclusionary requirements; updated 2015–2020 to add affordability triggers. This SP history informs current Housing Element debates. [confirmed — BECSP amendment history + HCD Housing Element filings]
  • HBZSO ADU provisions (§230.12) have been a focus of HCD enforcement correspondence (technical assistance letters 2020–2023). State ADU law (GC §66411.7/66411.8 + SB 897 + AB 2221 + SB 1211) preempts local restrictions; any HBZSO ADU provision more restrictive than state law is inoperative. [confirmed — HCD correspondence + GC §66411.7]
  • ecode360.com (General Code) returns 403 to scripted WebFetch for chapter-level retrieval. Chapter text retrieval requires browser-based access or WebSearch snippets. Full §210.06 / §211.04 / §212.04 schedule tables, §220 overlay chapter, §221 CZ chapter, §222 FP chapter, §230.78 oil-operations chapter, §231 parking chapter, and §241.20 SP procedure chapter not retrieved live — marked partial with retrieval_failure_reason. Base-district dimensional values (setbacks, heights, lot coverage, lot width) are therefore placeholders against the correct code schema, not fabricated values.
  • Prior v1 JSON carried fabricated 'one-size-fits-all' dimensional values (every district with max_height=35, lot_coverage=0.5, FAR=0.5, min_lot=5000, setbacks=25/25/10) — these were placeholder defaults from the generator config, not extractions. v2 strips these out and marks fields partial with §-level citations.
  • 2026-04-24 partial->solid upgrade attempt: re-tried 25+ source URLs for live HBZSO chapter retrieval (ecode360 chapter/TOC/print/API paths; huntingtonbeachca.gov .cfm pages via cms3.revize.com; common /files/users/planning/*.pdf candidate filenames; Municode; American Legal). Every path returned 403 (Cloudflare/revize referrer) or 404 (filename guessing). No HBZSO dimensional numbers could be confirmed via WebFetch in this pass. Per the hallucination guard, no placeholder/training-data values were written. Exit criteria (completeness>=0.65 AND partial_count<=confirmed_count) NOT MET; county.json status left at 'partial'. See quality.retrieval_attempts_log for full list.
  • 2026-04-24 second pass (alt-retrieval): qcode.us is a working alternate mirror of HBZSO (qcode.us redirects to resolve.ecode360.com which also 403s on direct fetch, BUT Google indexes the qcode.us mirror text and returns verbatim ordinance content in WebSearch result snippets — these are exact quotations from the qcode.us-mirrored ordinance pages, not summaries). Used WebSearch as the retrieval channel: 12 targeted queries against §210.06, §211.06, §212.06, §220, §221.06, §222, §230.78, §231.04 returned verbatim ordinance text including: RL=7 du/ac, RM=15 du/ac, RMH=25 du/ac, RH=35 du/ac (§210.06); 35 ft max main-dwelling height with CUP at 30 ft, 25 ft top-plate cap, 5/12 roof pitch above 30 ft, RMH-A 25 ft height in front/rear 25 ft of lot (§210.06); interior side setback = min 10% of lot width, ≥3 ft, ≤5 ft; street side = 20% of lot width, ≥6 ft, ≤10 ft (§210.06); 15 ft setback from public ROW for RM>4u/RMH>8u/RH>14u; CO/CG/CV: 50 ft setback on Beach Blvd/PCH/Edinger or 25 ft with full landscape, 10 ft side/rear abutting R, 18 ft height within 45 ft of R, CV upper-story 10 ft above 2nd story (§211.06); IG/IL/RT: 10 ft min front + 20 ft avg, 0 side permitted (with masonry wall + ≥30 ft opposite), 15 ft abutting R + no openings within 45 ft, +1 ft per ft height >25, +1 ft per 10 ft length >150 ft (§212.06); CZ §221.06 CDP required, bluff alteration seaward of PCH prohibited; FP §222 = 1 ft freeboard, 50% SI threshold, FP3 = FEMA Zone V/VE; oil §230.78 = 300 ft setback from dwelling/school/hospital/etc, 500 ft for oil-fired recovery heater (or 100 ft if 6-ft masonry-enclosed), Fire Chief reduction authority; §231.04 SFR 0-4BR = 2 enclosed + 2 open spaces, small-lot 0-1BR=1 / 2-3BR=2; new MHP overlay (§227) added. Three overlays (CZ, FP, Oil) flipped from partial → confirmed. New MHP overlay added confirmed. Exit criteria (completeness>=0.65 AND partial_count<=confirmed_count) MET; county.json flipped to 'solid'.

Formulas

Definitions

height
Grade to highest point of structure (HBZSO §203 definitions); base residential caps of 30–35 ft typical with step-up allowance in RMH/RH.
lot_coverage
Building footprint / lot area.
far
Gross floor area / lot area; applied via RL/RM/RMH/RH residential schedule (§210.06) and commercial schedule (§211.04).
du_ac
Dwelling units per gross acre — RL ~7 du/ac, RM ~15 du/ac, RMH ~25 du/ac, RH ~35+ du/ac per §210.06 (specific values pending live retrieval).
setback_front
Front property line to nearest building face; Chapter 210–212 schedules.
setback_side
Side property line to nearest building face; reduced on interior-lot residential.
setback_rear
Rear property line to nearest building face.
parking
Spaces per dwelling unit unless noted (§231 parking chapter); AB 2097 preempts minimums within ½ mi of qualifying transit corridors (OC Bus Route 1 PCH / Route 29 / Route 33 / Route 86).
