Application Process

  1. Confirm zoning and site constraints using the city's GIS and zoning resources before planning the work.
  2. For simple permits that do not require plan submittal, move directly to portal setup and submission. For larger projects, prepare plan sets and obtain any required architect or engineer stamps.
  3. Obtain outside-agency sign-offs that apply to the project, including Environmental Health, Air Quality, Water Resources, fire review, sewer or special district approvals, school fees, and local water district approvals where required.
  4. Create an OpenGov portal account and upload a California-issued driver's license.
  5. Upload plans and supporting documents through the portal, including agent authorization and a flood-zone elevation certificate if applicable.
  6. Staff reviews the submission, calculates fees, and sends a payment request.
  7. Pay by credit card in the portal or by check in the office using a printed invoice.
  8. After approval, print the approved permit and stamped plans, keep them on site, and schedule inspections through the portal.

Typical processing time: For plan-check projects, the city estimates about 4 to 8 weeks total: initial review 2 to 4 weeks, re-checks about 1 week, and payment request or permit issuance 1 to 2 weeks. Inspection lead times are typically 1 to 2 weeks.
