Most California jurisdictions require a site plan as part of a building permit application. The plan shows the property boundaries, existing and proposed structures, setbacks, access, and other information the planning or building department uses during review. Requirements vary by city and county, so we confirm what’s needed during the scope review.
Yes. We work from available source information — county records, assessor maps, satellite imagery, photos you provide, and any existing surveys or documents. Many California jurisdictions accept plans based on these sources for standard residential projects.
Site plans are delivered as scaled PDF files suitable for permit submission. If you need an editable CAD format (DWG or DXF), this can be included in the project scope at the time of your quote.
We confirm the delivery date after reviewing your project scope and available source documents. Timing depends on the property’s complexity and the information needed to prepare the drawings.
Yes. If a plan reviewer requests changes through written comments, we review those comments and make applicable revisions to the site plan. Revision support is part of our standard service — no surprise charges.
At minimum, we need the property address and a description of your proposed project. Helpful additions include any existing surveys, assessor maps, photos of the property, and any correspondence from your local building department about requirements.
