Local context

What do Rancho San Diego homes need?

East County garages in El Cajon, La Mesa, Santee, and Alpine tend to be older construction with concrete slabs that may need moisture mitigation before flooring goes in. Summer heat is significant in these areas, making a properly sized mini-split HVAC system essential for livability rather than optional. Older homes often have smaller electrical panels, and a subpanel or full panel upgrade is a common prerequisite for ADU conversions. Unincorporated county jurisdictions use the San Diego County permit office rather than city-specific plan check, which has its own timeline and requirements.
