How much does an ADU cost in Stockton?

We have not found a dated, Stockton-only cost survey as of November 2026. The nearest benchmark, Block Renovation's June 2026 Sacramento guide, puts detached ADUs at about $150,000 to $300,000 or more and garage conversions at about $80,000 to $150,000. Stockton's free permit-ready plans can trim design costs.

What does Stockton offer ADU builders?

The city has published free, preapproved floor plans for a studio, a one-bedroom and a two-bedroom unit, each with one bathroom, with expedited review when you build from them.

Its ADU flyer also notes that city impact fees do not apply to ADUs under 750 square feet, that school fees may still apply depending on the address, and that each ADU needs its own address.
