Once we receive your application and have created it in our system, we will review your plans. If your plans require corrections or if we need further information, we will contact you. Once you've gone through Steps 1 and 2, we will contact you to issue your permit. Depending on our workload and the complexity of the project, the process may take between 6-8 weeks from the date the City receives a completed application to the date when we issue your permit (subject to time limits set forth in California Government Code 65852.2).
