Assessor's Parcel

An Assessor's parcel is an area of land delineated on a map by the County for the sole purpose of collecting taxes on property. Each Assessor’s parcel is assigned a number (the Assessor’s Parcel Number or APN) that corresponds to a location on a page in a book of maps maintained by the Assessor’s Office.

You may obtain an Assessor's parcel map by one of the following options:

Purchase a copy at the County Administration Center, 1600 Pacific Highway, Room 103, in downtown San Diego or go to the Online Parcel Map Search on the Internet.​​

There are more than 29,128 Assessor’s maps, showing almost 1,001,029 parcels of land. These maps cover the county, including all the cities, as well as the unincorporated areas. ​

The parcel maps show the Assessor’s parcel numbers, recorded dimensions, acreage, street widths, parcel and lot boundaries, adjoining parcels and recorded map information.​

This office receives information from government maps, recorded maps, subdivision maps, record of surveys and road surveys.​

A Building permit is required to construct any new structure or improve existing buildings and other structures. The more common building permit applications are for new or remodels to single dwelling units, multi-dwelling units, commercial and industrial buildings, and accessory structures. 

Building construction plans and other documents must be submitted for review to ensure that construction projects comply with federal, state and local standards for building safety, accessibility and land use, zoning and standards that help safeguard life or limb, public health, property and welfare.

Zoning is the legislative process for dividing land into zones for different uses. Zoning laws are the laws that regulate the use of land and structures built upon it.

Permits and Zoning are regulated by the Cities and by the County in unincorporated areas. City and/or County staff review and approve these applications to ensure all applicable regulations are met.

For more information and how to apply for a building permit, please contact one of the County of San Diego Zoning Departments.
