Property and Zoning Research


CCMAP is an online mapping application. It provides access to Assessor property information and is updated on the first business day of each month. In addition to property assessment information, users can view map layers such as aerial imagery, general plan, zoning, creeks, school and fire station locations. Note the general plan and zoning information is available for unincorporated County areas only.

ePermits Center

The ePermits Center website provides access to Building Permit and Planning Application with real time statuses and history.

  • Permits and application history from 1/1/1980 to current date are shown on the ePermits Center.
  • Construction plans and/or other application documents are not available for viewing or download on the ePermits Center. See the Records Request section below to inquire about record or plan copies.

Records Request

The Records Research Division provides construction and planning records for properties.  Please note: we might not have records/plans for your inquiry based off the jurisdiction at the time the permit was issued.  We will notify you if we do not have records and/or if you need to contact the city.

  • Copies of construction plans, permit documents, reports, calculations, planning files, etc. may be requested.
  • There is approximately a ten business day turnaround time for the research.
  • Documents stamped by a licensed professional will need a release from the licensed professional and may take an additional 30 days to receive correspondence from the professional.
  • If you have additional questions after reviewing the Records Request Form (PDF), call (925) 655- 2713
