You have obtained the necessary approvals to receive a building permit for your residence. Construction may now begin! Periodic inspections are required to ensure the work complies with the approved plans and applicable codes. The following information is provided to assist you through the inspection process. If you need any clarification or assistance with the inspection process, please call us at (408) 299-5700.

Applicable Construction Codes

Your plans were reviewed for conformance with the provisions of the latest adopted edition of the Uniform Building, Mechanical, and Plumbing Codes, National Electric Code, State Building code and other County ordinances. All construction shall comply with the approved plans and applicable construction codes.

General Requirements

Every permit expires if work is not started or does not have a signed inspection within 180 days of permit issuance, or 180 days of the last signed inspection. Cancellation of the permit is automatic after 6 months with no approved inspection. If a written request is received prior to the expiration date, the Building Official may extend the permit for one 6 month period.
