Typical Inspections

The purpose of this document is to help clarify the typical sequence of building inspections required for; new dwellings, additions, remodels, commercial projects, etc. The basic rule here is; do not cover any portion of the work without the approval of your inspector. Your permit card lists the required inspections for your project. However, if you are unsure what work requires inspections, please contact your inspector who will be happy to assist you.

Procedure: A building permit is valid for one year from the date of issuance per County Code 12.10.335, and is extended six months thereafter for each approved progress inspection. This is not accumulative, after you have been approved for a progress inspection your permit will be extended six months from that date.

Progress Inspection: An inspection of a portion of work that demonstrates that the project is progressing towards a final inspection. It is up to the Building Inspector to determine that progress.

Typical Sequence of Inspections

The inspector will check the setbacks (distance from new form boards to the property lines). The property lines must be confirmed by a survey or existing survey hubs at the property corners.
