Common questions
01 What's the difference between a garage conversion and an ADU?
A garage conversion can be an ADU, a junior ADU, or just more living space attached to the main home. If it has independent utilities, kitchen, and bath, it's legally an ADU. Junior ADUs are a specific category up to 500 sqft with shared plumbing.
02 How much does a garage conversion cost in San Diego?
Attached conversion (no ADU): $80K–$140K. Junior ADU conversion: $105K–$180K. Full ADU conversion: $135K–$240K. Ranges depend on structural, MEP, and finish level.
03 How long does a conversion take?
10–14 months total. Design + permits: 4–7 months. Construction: 3–5 months.
04 Can I keep parking somewhere else?
In most SD jurisdictions, yes — parking replacement requirements were largely eliminated for ADUs within a half-mile of transit. Check the local overlay.
05 Is a garage conversion worth it vs a detached ADU?
Depends on scope and budget. Conversion is 30–50% cheaper and faster, but rents 15–25% less and adds less resale value. See our dedicated garage-vs-detached breakdown in the journal.
