County Of Marin: Assessor-Recorder

ASSESSOR MAPPING

Parcel Maps

Our office establishes and maintains a set of maps for assessment purposes delineating every parcel of land in the County. These parcel maps serve as the basis for the assessment of all real property in Marin County. The maps are continuously updated to reflect new subdivisions and surveys. These maps are available for review in room 208 and room 232. Copies may be purchased in the Mapping Section (room 232).

Assessor Parcel Combination Requests

An Assessor Parcel combination is two or more Assessor Parcels consolidated into one Assessor’s parcel resulting in a single annual property tax bill. Assessor Parcel combinations are completed for property assessment purposes only. This action does not imply legal lot status nor does it constitute legal lot approval by any planning/building authority. If you have any questions regarding legal lots, you should contact the appropriate planning/building authority where the property is located.

Assessor Parcel Combination Requests are subject to the following conditions:

Parcels to be combined must be in the same Tax Rate Area (TRA).
Parcels to be combined must be contiguous.
Parcels to be combined must be in the exact same ownership with same titles.
Property taxes for all parcels to be combined must NOT be delinquent.
Parcels to be combined must fit on to one Assessors 11” x 17” Map page.
Parcels are not noted as two or more distinct parcels of record as defined on official subdivision maps (Parcel 1, 2, or A, B, etc.) filed with the Marin County Recorder.
Parcels cannot be combined if one or more parcels are covered by an individual Notice of Merger (Owners need to contact the Planning Department of the local jurisdiction for information related to Notices of Merger.)
It is the property owner’s responsibility to determine if there are Notices of Merger on their parcels or if any parcels are noted as distinct parcels of record as shown on a recorded Parcel Map.

Note: If one parcel is under Open Space contract or Williamson Act and the other parcel(s) is/are not, the parcels cannot be combined for assessment purposes.

Applications for Assessor Parcel Combination must be made in person at the Office of the Marin County Assessor-Recorder located in Room 208 of the Marin Civic Center, 3501 Civic Center Drive, San Rafael, CA 94903. The fee for an Assessor Parcel Combination is $150 payable by cash or check.

If you plan to apply for an Assessor Parcel combination, please contact the Assessor Mapping staff at 415-473-5073 beforehand so that Mapping staff can verify that you meet the conditions as shown above.
