San Diego County unincorporated plans have a county paper trail
San Diego County keeps community plans for unincorporated communities, so the county layer can matter even when a nearby city name is familiar.
San Diego County’s General Plan applies to county land outside cities. Local community plans are part of that plan. They add maps, goals, and local policies for places such as Alpine, Fallbrook, Julian, and Borrego Springs.
First check that the parcel is outside a city. Then check that the county runs land use there. Not all land outside a city is county-run. Tribal land, state or federal land, and military land may have another agency in charge.
For county land, open the page for the local community. Look for its plan, land-use map, and design rules. Then use the county’s zone and property tools for the parcel. A community plan guides growth. It does not approve a project or replace a permit. Bring the address, parcel number, plan name, and work list when you contact Planning and Development Services.
