Full ADU in Spring Valley, CA.
Full ADU for Spring Valley homes, done by licensed San Diego County conversion crews. A full accessory dwelling unit conversion turns an attached or detached garage into a legally permitted, self-contained living space with its own kitchen, bathroom, and entry under California ADU law. We connect San Diego County homeowners with insured local crews that handle every phase from architectural drawings and permit submittal through framing, rough-in trades, insulation, drywall, and final inspection.
Why is full adu different in East County San Diego?
East County properties in El Cajon, Santee, La Mesa, and Alpine tend to have larger lots and older single-family homes with attached or detached garages that qualify for full ADU conversion under California law. Summer temperatures regularly exceed 100 degrees in El Cajon and Santee, which makes a properly sized HVAC system essential in any full ADU rather than an optional add-on. Unincorporated East County areas use the San Diego County permit office in Santee rather than city-specific plan check, which has its own submittal requirements and review timeline.
