Do all properties in the county have a recorded map?
No. A great many of the parcels of land existing in the county were created before legislation was enacted in 1972 requiring a subdivision final map or a parcel map to create new parcels. A deed, therefore, may be the only recorded document describing the boundaries of a longstanding parcel. Please note that a formal survey of an existing parcel is not normally a County prerequisite to the issuance of a building permit.
