Most plan checks require three sets of plans and two sets of structural calculations (if applicable). Depending on the type of project, additional documents and information may be required. All plans must be large enough to be clearly legible in detail and print.
Once a set of plans are approved, a building permit is issued to allow for construction. Construction activity generally must be completed within 180 days from the issuance of the permit. The City may also engage the services of pre-approved outside inspectors for certain types of construction projects.
At the conclusion of all construction activities, including inspections, a permit will be closed or finalized. After the final inspection, the permit and plans are archived by the City and may be viewed over the counter.

Effective January 1, 2019 Assembly Bill (AB) 2913 adds a new Health and Safety Code Section 18938.6 to provide that a Building Permit can remain active so long as the work authorized by the permit was commenced within 12 months, and the work is not abandoned. In addition, the building official may grant one or more extensions of time for periods of not more than 180 days per extension. A permittee requesting such extensions must make the request in writing and demonstrate justifiable cause for the extension.
