Junior ADU in San Ysidro, CA.
Junior ADU for San Ysidro homes, done by licensed San Diego County conversion crews. A junior ADU converts an attached garage into an independent living space up to 500 square feet that shares plumbing and an entry with the main home, qualifying under California JADU law with lower permit fees and a simpler plan check process than a full ADU. We connect San Diego County homeowners with insured local crews that handle the full conversion from permit drawings through framing, insulation, drywall, flooring, and kitchen and bathroom connections.
Why is junior adu different in South County San Diego?
South Bay attached garages in Chula Vista and National City are frequently converted to JADUs because the lot sizes in these 1960s-era neighborhoods are tight enough that a detached ADU or room addition is not feasible without encroaching on setbacks. Chula Vista has seen strong JADU activity alongside its full ADU approvals, and the permit process there is well-understood by the local crews we refer. Many South Bay homeowners use a JADU to house family members rather than as a rental, which means the owner-occupancy restriction in California JADU law is not a practical limitation.
