Questions
Property Line Map: what people ask
Is the county GIS map my legal property line?
No. A GIS parcel map is drawn from records. Under California law, locating, re-establishing or retracing a property line, or setting a corner monument, is land surveying, which a licensed land surveyor does.
How close to the line can an ADU go in California?
A city or county can require no more than 4 feet from the side and rear lot lines for a new ADU, and no setback for an existing structure converted in the same place and size.
Can I check the flood zone too?
Yes. FEMA's free FIRMette tool prints a full-scale section of the official flood map on a home or office printer, and FIRMettes can be used in all aspects of the National Flood Insurance Program.
