Building Inspection Services Division

Beginning May 4, 2020, the Community Development Department will be offering limited in-person services through the Building Inspection Services Division. Individuals will be able to apply for and receive building permits for ALL construction project types. Services are limited to protect the health of City staff and the public and the following procedures will be used until further notice:

  1. Building Permit applications and resubmittals may be submitted directly to the Building Inspection Services Division from Monday through Friday, 8 am to 4 pm, at the second floor of City Hall, located at 200 H Street in Downtown Antioch. The main entrance and elevator are open and a rack has been provided on the second floor for contact-free drop-off of applications and resubmittals. No fees are due at the time of Building Permit application. A Building Permit application form is required and is available here.
  2. Building Permits may be picked up on Tuesday, Wednesday, and Thursday by appointment only. A Building Inspection Services staff member will contact applicants when the plans have been approved and the permit is ready to issue. At that time of the appointment, individuals may enter the department and work directly with staff. Protective barriers are in place for safety. Once issued, the applicant will be directed to the Finance Department to make payment.
  3. Building Inspections will be available for all approved and active projects. Please call the Building Inspection hotline to make an appointment at (925) 779-7065.
