01

Locate your parcel

Use the LAFCO map to see which city or county office to contact. The county building department has its own program for unincorporated properties.

02

Walk the route to the front door

Sketch the path from the street to the future entrance. Note trees, changes in level, utility equipment and the garden space you want to keep.

03

Bring the right questions

With the jurisdiction identified, ask about a conversion, attached home or detached cottage. The answer will help you decide which design studies to explore.
