Financing an ADU Garage Conversion across San Diego County
Homeowners in San Diego County finance garage conversions through a mix of home equity loans, HELOCs, cash-out refinances, and renovation-specific loan products. Financing cost depends on your lender, credit profile, and current rates, not on the conversion itself, so get quotes from more than one lender before committing.

Common questions
Do any programs help finance ADU construction specifically?
Some lenders offer renovation loan products that account for the home's value after the ADU is complete, rather than just current equity. Loan programs and terms change, so check current offerings with a mortgage lender rather than relying on a fixed list.
Can rental income from the ADU help qualify for financing?
Some lenders factor in projected rental income for qualification purposes, but policies vary significantly by lender. Ask directly whether a specific loan product counts projected ADU rent toward your qualifying income.
Do I need the full budget upfront or can financing cover it in draws?
Most construction and renovation loans release funds in draws tied to project milestones (permit issued, framing complete, final inspection) rather than a single lump sum. Your crew coordinates documentation for each draw request.
