Coastal Remodeling in Hermosa Beach
After the City approves, coastal permits go to the Coastal Commission, a second agency.

Steps From the Strand
The coastal step here is different from the neighbors', and it catches people out. Because the City's Local Coastal Program is not fully certified, Coastal Development Permits are handled through the California Coastal Commission's South Coast District after the City approves the project in concept: a second agency, not just a second counter.
We build that into the plan, along with the reality that most lots near the beach are narrow.
Predominantly narrow rectangular lots with compact rear yards near the beach, and larger, more conventional parcels farther east.
The team that plans your Hermosa Beach project is the team that builds it.

Permits in Hermosa Beach
City of Hermosa Beach Community Development Department, Building and Safety Division
Building permits, plan check and inspections come from the Building and Safety Division within the City's Community Development Department, with zoning review handled by the Planning Division. In the Coastal Zone a Coastal Development Permit is required in addition to the building permit, and those permits are processed through the California Coastal Commission's South Coast District after the City has approved a project in concept.
Common triggers include new development, increases in floor area or height beyond ten percent, intensification of use, and work affecting coastal resources or a site with a prior coastal permit. Duration varies with the scope and the coastal review path.
Permit details checked September 2026 against California Coastal Commission. Rules change, so we confirm them again for your parcel.
What We Plan For
- Coastal Commission permit coordination
- Narrow-lot and alley-access construction planning
- Corrosion-resistant equipment specification
Beach-side parcels sit on deep sand, so excavation for a pool, spa or subterranean level needs shoring and a soils-driven foundation approach rather than a standard footing.
Many lots are narrow, with alley-only or walk-street access, which caps equipment size and forces off-site material staging.
The bluff separating the flats from the east side produces steep rear yards where retaining and drainage carry a large share of the budget.
Ocean exposure accelerates corrosion on pool equipment, hardware and metal railings within a few blocks of the water, which changes what is worth specifying.
