Summary

Placer County Code § 15.04.100 lets the chief building official authorize alternative inspection procedures, using declarations from duly licensed professionals, except where the California Building Code requires special inspection under Chapter 17. No certificate of occupancy issues until every applicable department and the serving fire district or CAL FIRE sign off, and occupying a structure before that approval is a public nuisance under § 15.04.110.

These county ordinances apply to unincorporated areas of Placer County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Section 110.1 - General. Add the following to Section 110.1 of the CBC: Except where special inspection is specified in Chapter 17 of the CBC, the chief building official may authorize alternative inspection procedures requiring declarations from duly licensed professionals.

Frequently Asked Questions

Can Placer County waive a standard building inspection?
Yes. Under § 15.04.100, the chief building official may authorize alternative inspection procedures based on declarations from duly licensed professionals, in place of a routine county inspection, except where California Building Code Chapter 17 requires special inspection, such as for structural welding or high-strength bolting.
Can I move into a new home before the certificate of occupancy is issued?
No. Section 15.04.110 bars occupancy until the fire district or CAL FIRE and every applicable county department have signed off, and it declares early occupancy both a code violation and a public nuisance.
How do I appeal a building inspector's decision?
File an appeal with the building services division within 30 days of the decision, on the division's forms and with the required non-refundable fee under § 15.04.120. The nine-member building board of appeals created by § 15.04.130 then hears and finally determines the appeal.
