Building Inspections
Construction work or work that requires a permit is subject to inspection. It is important to call for an inspection once each phase of the work requiring an inspection is completed. The work shall remain accessible and exposed for inspection purposes until it has been approved. Photographs and videos are not accepted for inspection purposes. Approved building plans must remain at the site and made available to the inspector along with the permit card. For additional information regarding your type of inspection, please click into the category titled “Inspection Types.”

How do I request an inspection?

Inspection Requests
Before you can request an inspection, you must first obtain the permits for the work you intend to do. You may request an inspection in person, or you can schedule an inspection on our Online Permit Portal (https://aca.accela.com/lancaster). Inspection requests received prior to 11:59 p.m. can be scheduled for inspection on the following workday. Requests received after Midnight can only be scheduled for inspection on the second workday or later following the request.  Scheduled inspection times can be viewed on the Online Permit Portal.

Inspection Record Card
An Inspection Record Card must be posted or made available to allow the inspector to make the required entries relative to inspection of the work. This card shall remain posted or made available until final approval has been granted.

Overtime Inspections
Overtime inspections are available and are based upon inspector availability. These inspections must be prepaid and coordinated with your inspector.

Special inspectors are required to possess individual certification by a recognized issuing authority for the type of work to be inspected.

All special inspection work shall be performed pursuant to the provisions of the California Building Code, Section 1701 as outlined in the approved plans and specifications. The special inspector shall be present on the job site at all times that work requiring continuous inspection is in progress, and periodic inspection shall be performed as required by the design authority and the building official.

Reporting
