Hermosa Beach, California Zoning Map

Hermosa Beach has 11 designated Specific Plan Areas, each with its own adopted standards. SPA-7 is the largest at about 15 acres and SPA-8 covers about 13 acres; both are significant enough to warrant full specific plan review before any site analysis. SPAs override base zoning controls, so a parcel inside a SPA must be evaluated against that plan's permitted uses, density limits, design standards, and parking requirements rather than the underlying zoning district.

Hermosa Beach has meaningful multifamily zoning: R-2 (74 acres), R-2B Limited Multiple Family (39 acres), and R-3 Multiple Family (91 acres) are available for denser residential projects. However, the city's compact size and coastal location mean land values are high and parcels rarely assemble into large development sites. California's density bonus law and ADU statutes provide state-level tools to extract additional units from qualifying parcels, though local design standards and coastal zone rules add review layers.

Yes - Hermosa Beach is entirely within the coastal zone, meaning most development projects require a Coastal Development Permit (CDP) in addition to local planning approvals. Projects within the Open Space, OS-1, and OS-O zones near the beach and strand are subject to particularly close Coastal Commission review. Developers should determine whether a project triggers CDP requirements and whether the Local Coastal Program (LCP) allows the proposed use before advancing site selection.

With C-3 General Commercial covering only about 30 acres and C-2 Downtown Commercial at 13 acres, Hermosa Beach's commercial land supply is limited and heavily oriented toward neighborhood retail, dining, and personal services. The R-P Residential Professional zone (6 acres) serves small office users. New commercial projects face strong competition for a thin supply of commercially zoned parcels, and ground-floor retail in mixed-use residential buildings in R-2B or R-3 zones may require SPA or specific plan entitlement.

The R-1A (Two Dwelling Units Per Lot) zone covers about 5 acres and explicitly permits two units per lot by right - predating California's SB-9 framework. This district signals corridors where the city historically accepted duplex density in single-family contexts. R-1A parcels are smaller in number but offer a clear path to two-unit development without the additional SB-9 ministerial review steps, making them efficient for small-scale residential developers or investors pursuing duplex conversions.
