Can you build an ADU on your lot?
Type in your address. We pull your actual parcel from the county and show what California law allows on your lot — detached, attached, a garage conversion, or a junior ADU — free, in about a minute.
Gold = the space left after California's 4 ft side & rear ADU setbacks (front setback per the existing home). This is a planning pre-check, not a survey.

We confirm the details a website can't — your city's current rules, utilities, and what your ADU would cost — and email you the result. No obligation.
You're in — thank you.
Your lot review request is with our team. We'll email your result shortly. Questions sooner? Call ADU Cities at 888.627.1131.
Pre-check only — not a permit determination. City rules, coastal zone, fire severity, historic status, HOA rules and utility capacity can change what's allowed on a specific lot. Parcel boundaries are approximate and are not a survey.
