Hayward limits lot coverage by buildings to roughly 40% in single-family zones. Impervious surface totals including driveways are regulated through stormwater and landscape standards.
Lot coverage in Hayward is regulated under the Hayward Municipal Code zoning ordinance. Single-family residential (RS) districts typically limit total building footprint to approximately 40% of the lot area, though the exact percentage varies by subdistrict and lot size. Multi-family and commercial zones have higher coverage allowances tied to floor area ratio (FAR) rather than footprint percentage. Impervious surface coverage including patios, driveways, and walkways is further regulated through the Countywide C.3 stormwater requirements for projects creating or replacing over 2,500 square feet of impervious area. Accessory Dwelling Units built under state law do not always count toward coverage limits if they comply with ADU size caps. Pools, decks under 30 inches, and detached accessory structures have specific coverage treatment in the zoning code.
