Hayward · new construction permits
Hayward new construction permits.
What it actually takes to permit a ground-up build in Hayward: jurisdiction, plan check, inspections, and the local overlays that change the path. Every link below points at an official City of Hayward Development Services Department — Building Division resource.
Quick answer
New single-family permits in Hayward are issued by City of Hayward Development Services Department — Building Division; California Title 24 Part 6 and CALGreen Part 11 apply statewide on top of any Hayward reach-code amendments.
Homeowner & investor takeaway
Run the CGS EQ Zone App before scoping. If your parcel touches the Alquist-Priolo corridor, expect a fault-trenching investigation; on hill parcels, HPD slope-band caps decide buildable mass long before architecture starts.
Local jurisdiction.
Permits are issued by City of Hayward Development Services Department — Building Division (Alameda County). Use the official portals below — do not rely on third-party permit aggregators.

Permit types typically involved.
Building permit
Required for a new dwelling unit, including structural, MEP, and envelope review.
Grading / drainage
Grading thresholds and Low Impact Development (LID) stormwater requirements apply per City of Hayward Development Services Department — Building Division; sloped parcels require geotech and an erosion-control plan.
Sewer / utility
Municipal sewer service in developed Hayward parcels; verify lateral condition and any point-of-sale sewer compliance requirement before scoping. PG&E electric/gas; East Bay Municipal Utility District (EBMUD) or City of Hayward Water depending on neighborhood; coordinate service-upgrade lead times early.
Electrical / mechanical / plumbing
Often pulled with the building permit; some jurisdictions require separate sub-permits per trade.
Title 24 compliance
California Energy Commission Climate Zone 3. New single-family homes must comply with the current Title 24 Part 6 envelope, HVAC, hot-water, and rooftop solar-PV requirements.
CALGreen
CALGreen Part 11 mandatory measures (≥65% C&D waste diversion, water-efficient fixtures, indoor-air-quality measures) apply to all new homes. Hayward may layer reach-code or local green-building amendments — confirm the current adopted ordinance at intake.
Plan check process.
Plan check focuses on Title 24, structural lateral design, and grading/erosion control for any project that touches the Hayward Fault Alquist-Priolo corridor.
Entitlement & planning review.
Most R-1 SFRs are ministerial; HPD and hillside parcels above ridge-line thresholds require Site Plan Review with the Planning Commission.
Inspections.
City of Hayward Development Services Department — Building Division schedules inspections through its permit portal; foundation, framing, rough trades, insulation, drywall, and final are the standard hold points for new SFRs in Hayward.
Local overlays & constraints.
Hayward uses Single-Family Residential (RS) districts with sub-district minimum lot sizes; Hillside Residential (RH) and Hillside Planned Development (HPD) overlays apply across the eastern hills.
Hillside. Hillside Residential (RH) and Hillside Planned Development (HPD) overlays govern slope-band density, retaining-wall heights, ridgeline protection, and grading limits.
Wildfire / WUI. Eastern hill parcels are in CAL FIRE Very-High Fire Hazard Severity Zone; Chapter 7A applies on mapped lots.
Seismic. The Hayward Fault Alquist-Priolo zone runs the length of the city along Mission Boulevard / Foothill Boulevard — a foundational design constraint for any custom home on or near that corridor.
Common delay drivers.
Risk 1
Fault-trench results forcing foundation redesign
Risk 2
HPD slope-band recalculation reducing buildable area
Risk 3
VHFHSZ exterior-spec swap mid-design
Prepare before submittal.

- Order soils / geotech early — many overlays require it before plan check.
- Complete Title 24 energy modeling and confirm CALGreen targets.
- Have a clear utility upgrade plan (sewer lateral, panel, gas) documented.
- Pre-assemble any overlay-specific studies (hillside, coastal, fire, flood).
