- Does my Alameda home additions project need a Coastal Development Permit?
- If the parcel sits inside the Coastal Zone boundary, yes — a CDP from the local LCP or the CA Coastal Commission stacks on top of the Alameda Permit Center building permit. We screen the parcel against the Coastal Zone map at contract.
- Is my Alameda property in a historic district — and does that change the home additions permit?
- Likely yes — exterior alterations on contributing structures in Alameda's historic overlays need design-review approval before plan check accepts the building permit. We file the historic clearance in parallel to keep schedules tight.
