What Drives Survey Costs in Marin County
Several factors are specific to this county and affect what you will pay.
Steep Hillside and Canyon Complexity
Much of Marin County is steeply hilly, with wooded canyons, narrow ridgelines, and limited access roads throughout Mill Valley, Fairfax, San Anselmo, and the Mt. Tamalpais watershed area. Hillside surveys here require significant field time to locate original monuments and navigate dense vegetation. Some canyon lots have original 1920s-era subdivision stakes that have been buried, removed, or moved by decades of earth movement.
Bay and Tidal Shoreline Properties
The eastern portion of Marin County fronts San Francisco Bay and Richardson Bay. Properties in Sausalito, Tiburon, Belvedere, and along the Corte Madera shoreline involve tidal easements, Bay Conservation and Development Commission (BCDC) jurisdiction, and historic bay fill boundaries. These coastal surveys require knowledge of public trust doctrine, State Lands Commission records, and BCDC's 100-foot shoreline band regulations.
Coastal and Point Reyes Area
Western Marin includes Point Reyes National Seashore and a broad agricultural coastal zone. Private in-holdings adjacent to National Seashore land require careful federal boundary coordination. Coastal properties in Bolinas, Stinson Beach, and the west Marin coast carry significant coastal erosion and tsunami hazard risk that can affect survey scoping and flood zone analysis.

How to Get an Accurate Quote
The most reliable way to get a fair price is to contact multiple licensed surveyors and provide your assessor parcel number (APN). You can find your APN on your property tax bill or through the Marin County Assessor-Recorder's Office at https://www.marincounty.org/depts/ar. Surveyors use the APN to pull existing records before quoting, which makes their estimates more accurate. Get at least two to three quotes before deciding.
