Naming convention
mixed

Base euclidean districts (RL, RNP, RM, RH, CN, CG, CR, IND) for most of city. Downtown core and Mission Boulevard corridor governed by form-based codes (HMC Ch. 10 Articles 25–26) that supersede base district standards. Transit Oriented Development overlay applies around BART and BRT stations. | naming_convention_raw=alpha-numeric-with-form-based-suffix ; code_type_raw=euclidean_with_form_based_overlays ; sub_flags_raw=[form-based-dominant-in-core, transit-rich-bart, seismic-hazard]

Worth knowing
  • Hayward Fault through central city. The Hayward Fault is an active strike-slip fault classified as an Alquist-Priolo Earthquake Fault Zone. Its trace runs NW–SE through downtown and central Hayward, imposing a 50-ft habitable-structure setback per CA PRC §2623 and excluding affected parcels from SB 9 / AB 2011 / SB 423 ministerial streamlining. This is one of the most consequential geographic constraints on Hayward's housing pipeline.
  • Form-based code dominance in core areas. Downtown (HMC Ch. 10 Article 26) and Mission Boulevard (Article 25) form-based codes regulate height, setbacks, and use through building types rather than traditional zoning tables — a parallel regulatory track distinct from standard base-district zoning. Regulating code PDFs contain zone-specific height caps not fully extracted live.
  • Two BART stations = broad AB 2097 coverage. Hayward Station (downtown) and South Hayward Station trigger AB 2097 parking-elimination buffers covering a substantial portion of the city's housing-opportunity geography. Combined with AC Transit high-frequency bus overlap, AB 2097 materially reshapes pro-forma parking requirements.

CA-ADU-GC§66411.7-66411.8applies
Qualifying condition
All CA cities. Hayward's RL/RNP, RM, RH, CN-R, CG/CR, DM, SMU, and mixed-use districts must permit ADUs by-right per state law. Hayward implements via HMC Chapter 10 ADU provisions. | 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 beyond statute; up to 8 ADUs on qualifying multifamily lots under SB 1211 (2025). Preempts any local minimum lot size, owner-occupancy, or parking within 0.5 mi of Hayward/South Hayward BART or qualifying transit.
CA-SB9-GC§65852.21-66411.7applies
Qualifying condition
Hayward is a CA general-law city with R-1-equivalent RL/RNP single-family districts. SB 9 applies per-parcel conditional on exclusions. Hayward contains Alquist-Priolo Earthquake Fault Zones along the Hayward Fault trace (strike-slip, NW–SE through central city), FEMA SFHA along San Lorenzo Creek and bay shoreline, and portions of hillside east of the city that partially overlap CalFire Very High Fire Hazard Severity Zones (per-parcel check required). No coastal zone. No city-designated historic district overlay identified. | title=SB 9 — California HOME Act (Lot Splits + Duplex Conversion) ; effect_on_city=Ministerial up-to-4-units on qualifying RL/RNP parcels (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 ministerial procedural limits. Alquist-Priolo parcels along Hayward Fault trace are statutorily excluded. ; per_parcel_conditional=True ; exclusions=['Alquist-Priolo Earthquake Fault Zones (Hayward Fault)', 'FEMA SFHA (San Lorenzo Creek + bay shoreline)', 'CalFire VHFHSZ (east hillside parcels per-parcel)', 'coastal zone (N/A — inland city)', 'designated historic districts (none identified)']
CA-DensityBonus-GC§65915applies
Qualifying condition
Statewide. Hayward's local Density Bonus Ordinance imposes a 55-year affordability covenant (stricter than state 55-yr minimum for rental LI; aligns with state). AB 1287 stacking to 100% density bonus available. Applies on RM, RH, CN-R, CG/CR, DM, SMU residential/mixed-use districts. | title=State Density Bonus Law + AB 1287 (2023) + local DB ordinance (55-yr affordability) ; effect_on_city=Up to 100% density bonus (AB 1287 stacked) on qualifying residential components. Can waive base du_ac, max_height_ft, and base setbacks as concessions/incentives (1 per 10% VLI, 2 per 20%, 3 per 30%). State §65915(p) parking ratios (0.5 studios/1BR; 1.0 2–3BR; 1.5 4+BR) preempt local parking ratios on affordable components and stack with AB 2097 elimination.
CA-AB2097applies
Qualifying condition
Hayward is served by two BART heavy-rail stations: Hayward Station (698 B St, downtown) and South Hayward Station (28601 Dixon St). Both qualify as 'major transit stops' under PRC §21064.3 (rail stations with defined service). AC Transit operates high-frequency bus lines (1/1T, 97, 99, transbay lines); intersections meeting 15-min peak-headway threshold also qualify. Parcels within 0.5 mi of qualifying stops are AB 2097 eligible. | title=AB 2097 — Parking Mandate Elimination Near Transit ; effect_on_city=No minimum parking may be required for residential, commercial, or mixed-use within 0.5 mi of Hayward BART, South Hayward BART, or qualifying AC Transit high-frequency bus intersections. Preempts any HMC Ch. 10 parking ratios within buffer. Stacks with Downtown Specific Plan (Article 26), Mission Blvd FBC (Article 25), and state Density Bonus parking ratios. ADA + bicycle parking still required.
CA-SB423-GC§65913.4applies
Qualifying condition
SB 423 applies to sites zoned residential or mixed-use in cities not meeting their RHNA share, or in cities that are HCD-non-compliant. Hayward 6th-cycle Housing Element (2023–2031, RHNA 4,760 under ABAG) was HCD-certified. Eligibility tier (10% vs. 50% affordability) depends on HCD Annual Progress Report determination. Applies on RL/RNP (for qualifying multifamily on applicable parcels), RM, RH, CN-R, CG/CR, DM, SMU districts. Alquist-Priolo fault zones, VHFHSZ, and sites with recent tenant displacement are excluded per statute. | title=SB 423 — Streamlined Ministerial Multifamily Approval (extends SB 35, 2024–2036) ; effect_on_city=If eligible at 10% tier: ministerial by-right approval for qualifying multifamily ≥10% affordable (LI rental / moderate for-sale). 50%+ affordable bypasses design review. Prevailing wage / skilled-and-trained workforce requirements for 10+ unit projects. Alquist-Priolo parcels along Hayward Fault excluded. ; search_performed=HCD APR SB 423 determination list not fetched live (JS-rendered dashboard).
Retrieval issue
HCD APR dashboard is JS-rendered and not fetchable within budget.
CA-AB2011-GC§65912.100applies
Qualifying condition
Hayward has commercially-zoned parcels along defined corridors (Mission Boulevard, Foothill Boulevard, A Street, Jackson Street, Hesperian Boulevard, Tennyson Road, Industrial Parkway) that qualify as 'commercial corridors' under AB 2011. Hayward's published SB 6 / AB 2011 FAQ (Aug 2023) affirms AB 2011 is active on Specific Plan Area (SPA) corridor sites. | title=AB 2011 — Affordable Housing and High Road Jobs Act ; effect_on_city=Ministerial approval for qualifying multifamily on CN/CN-R, CG/CR corridor sites (excluding industrial-only and office-only zones). 100% affordable bypasses discretionary review. Minimum density cannot be less than Hayward's default for the area. Overlaps with SB 423 — developers choose pathway. Prevailing wage required.
Non-applicable laws (2)
CA-BuildersRemedy-GC§65589.5(d)(5)applies
Qualifying condition
Hayward adopted its 6th-cycle Housing Element (2023–2031) for ABAG region with RHNA of 4,760 units. HCD certification status at time of research is compliant. AB 1893 (2024) codified procedural requirements. If Housing Element becomes non-certified mid-cycle, Builder's Remedy reactivates. | title=Builder's Remedy (Housing Accountability Act) ; effect_on_city=Contingent. While Housing Element certified: Builder's Remedy dormant. If non-certified: projects with 20% LI or 100% moderate-income bypass all local zoning (height, density, FAR, use, setbacks); city may only deny on preponderance-of-evidence health/safety findings. ; search_performed=HCD Housing Element Compliance dashboard not retrieved live (JS-rendered).
Retrieval issue
HCD compliance dashboard is JS-rendered; certification status per City statement retained pending per-parcel project-level check.
CA-SB10under_review
Qualifying condition
SB 10 is permissive — authorizes but does not require cities to zone up to 10 units/parcel near transit or in urban infill via simple resolution (CEQA-exempt). No evidence Hayward has adopted an SB 10 resolution; Downtown and Mission Blvd form-based codes were adopted through standard rezone. | title=SB 10 — Local Upzoning Authorization ; effect_on_city=None unless/until Hayward adopts an SB 10 resolution.

Quirks & notes

  • Hayward Fault through central city. The Hayward Fault is an active strike-slip fault classified as an Alquist-Priolo Earthquake Fault Zone. Its trace runs NW–SE through downtown and central Hayward, imposing a 50-ft habitable-structure setback per CA PRC §2623 and excluding affected parcels from SB 9 / AB 2011 / SB 423 ministerial streamlining. This is one of the most consequential geographic constraints on Hayward's housing pipeline.
  • Form-based code dominance in core areas. Downtown (HMC Ch. 10 Article 26) and Mission Boulevard (Article 25) form-based codes regulate height, setbacks, and use through building types rather than traditional zoning tables — a parallel regulatory track distinct from standard base-district zoning. Regulating code PDFs contain zone-specific height caps not fully extracted live.
  • Two BART stations = broad AB 2097 coverage. Hayward Station (downtown) and South Hayward Station trigger AB 2097 parking-elimination buffers covering a substantial portion of the city's housing-opportunity geography. Combined with AC Transit high-frequency bus overlap, AB 2097 materially reshapes pro-forma parking requirements.
  • Multiple preemption pathways integrated. Hayward explicitly integrates AB 2097 and AB 2011 into its core code (per published SB 6/AB 2011 FAQ), suggesting dual compliance and developer choice in application pathway.
  • 55-year affordability covenant. Hayward's local Density Bonus Ordinance imposes 55-year affordability — aligns with state rental LI minimum but is on the stricter end for for-sale moderate-income, indicating strong inclusionary intent.
  • Hayward Executive Airport (KHWD) AIA. West Hayward parcels are subject to the Alameda County Airport Land Use Compatibility Plan for KHWD — height envelopes per FAA Part 77 surfaces and noise-compatibility restrictions in 65 CNEL contour are additive constraints on base district standards.
  • Municode platform access. library.municode.com/ca/hayward is the City's authoritative self-published code portal. Scripted WebFetch of chapter pages is rate-limited; section text retrievable via search snippets but regulating code PDFs (Article 25/26) require browser-based retrieval for table extraction.
