How long does the permit process take?

The length of the permit process depends on the type of application, project, and situation. Generally, the County’s building plan check process takes two to four weeks. Many projects also have to go through local planning application or process as well. Applicants should visit the Application & Permit Center or call 925-674-7200 to discuss their project in more detail.
