What to send us

The property address is the only thing we need to start. With it we pull the parcel record, the zoning, the setbacks and any overlay that applies, then reply in writing within 48 hours with what size ADU fits and a rough budget. If you want a faster and more accurate answer, add any of these:

  • What you want to build: a detached unit, a garage conversion, a junior ADU, or not sure yet
  • Whether there is an existing garage or back structure, and roughly how old it is
  • Whether the lot is flat or sloped, and whether a truck can reach the back yard
  • Any past permits, violations or unpermitted rooms you already know about

What happens after you reach out

First comes the free lot check, done from records with no site visit. If the numbers work for you, the next step is a site visit where we find the sewer lateral and electrical service, check equipment access and measure any structure you want to convert. You get a written feasibility report from that visit before any design fee. The full sequence, from lot check to certificate of occupancy, is laid out on the about page, and typical timelines are in how long it takes to build an ADU.

Which office will permit your ADU

Los Angeles County is not one permit desk. Where your lot sits decides who reviews the plans, and that changes the timeline:
