Overview
Code type
euclidean with form based overlays
Naming convention
alpha-numeric-with-form-based-suffix
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.
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.
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.
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.
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.
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.
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.
Non-applicable laws (2)
CA-BuildersRemedy-GC§65589.5(d)(5)confirmed
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.
Retrieval issue
HCD compliance dashboard is JS-rendered; certification status per City statement retained pending per-parcel project-level check.
CA-SB10not_applicable
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.

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.

- Detailed parking requirement ratios and setback reductions for individual base-district zones — referenced in Chapter 10 but full specification matrices not extracted
- SB 423 formal HCD APR tier determination (JS-rendered dashboard not fetched live)
- Administrative procedures for SB 9 and AB 2011 applications — substantive ordinances exist but procedural guidance may be at staff level
- FAR bonuses, development fees, and variance procedures — municipal code subsections exist but detailed values not accessible from summary sources
