Building Permit Information

Permit Requirement Information

Building, electrical, plumbing, sewer, and mechanical permits are issued Monday through Friday, 7:30 a.m. - 4:30 p.m.

A building permit may be issued to a California licensed contractor or an owner-builder residing in the single-family residence for which the permit is for. Permits for commercial, industrial or multiple residential projects (townhomes, condominiums, apartments, duplexes, etc.) are only issued to California licensed contractors.

  • An agent may pull a permit on behalf of a licensed contractor however, an original, notarized letter of authorization on company letterhead from the license holder must be provided. The letter must not exceed one year from date of issuance. 
  • An agent may pull a permit on behalf of an owner-builder living in a single-family residence however, the "Notice to Property Owner", "Authorized Agent Form", and an original notarized letter of authorization from the property owner must be received prior to issuance. The "Notice to Property Owner" and "Authorized Agent Form" can be found in our "Building Handouts/Forms" section.    

Generally, any new construction, additions, alterations or repairs to an existing building, including re-roofs, fireplaces, swimming pools, carports, remodels, hardscapes, etc., requires a permit. However, permits must be issued in person at our Building counter. We are pleased to announce that as of June, 2010, we are utilizing the Accela permitting system, which automates and improves how we deliver services to the public and maximize quality, timeliness, and cost-effectiveness.

  • You may refer to our "Building Handouts/Forms" section for General Handouts, Permit Forms, and Submittal Requirements.
