Subdivisions and Mapping

Public Works' mapping division processes and reviews all subdivision projects that occur in San Francisco, including all condominium conversions.  We also provide surveying services for all city agencies.

To increase efficiency and reduce paper consumption, the Office of the City and County Surveyor requires that all project applications be submitted electronically.*

  • Paper applications will be returned to project applicants.
  • As our applications are currently being updated, disregard application language which calls for paper submittal.
  • Applications must be entirely complete or will be rejected.
  • Application re-submittals are subject to an additional $250.00 administrative fee.
  • Electronic file size submittal in any one email is limited to 20 megabytes.  (Multiple emails or “Zip” files may be used.)
  • Digital media is accepted by post or messenger delivery.
  • Submit each application document as a separate PDF file. (Do not bundle multiple documents into one PDF.)
  • Document file naming convention should reflect the name of the document as found in the application checklist.
  • *Note: All documents requiring notarized signature must be submitted in both electronic and original hardcopy format.
