A report is a starting point, not a permit or a legal opinion. Zoning and parcel data come from LA City Planning (ZIMAS), LADBS, and the county assessor and GIS offices, and can be out of date. Confirm with your city or county before you build. Pre-approved plans belong to the firms named on each plan.
