FAQ: San Diego ADU questions
Is a garage conversion cheaper than building a detached ADU?
It can be, because you start with an existing structure. But conversions still require insulation, plumbing, electrical, and often significant upgrades to meet current standards. A site evaluation and realistic scope are the only way to compare accurately.
How long does it take to build an ADU?
Total time depends on design decisions, permitting, and construction scope. The fastest ADU projects are those with stable scope and early material selections.
Do ADUs require permits and inspections?
Yes. ADUs are dwelling units with life-safety requirements. Permits and inspections protect you and ensure the unit is legal.
