New construction · Hayward

How does hillside zoning affect new construction in Hayward?

Hillside parcels in Hayward carry slope-based limits on FAR, retaining walls, grading export, and access. Hillside Residential (RH) and Hillside Planned Development (HPD) overlays govern slope-band density, retaining-wall heights, ridgeline protection, and grading limits.

What changes the answer in Hayward.

Hillside Residential (RH) and Hillside Planned Development (HPD) overlays govern slope-band density, retaining-wall heights, ridgeline protection, and grading limits. 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. Site access in Hayward can require temporary street-use or encroachment permits depending on street width, on-street parking restrictions, and proximity to schools or transit corridors.
