How are inspections scheduled?

The county's portal guide says online inspections can be scheduled until 7:00 a.m. on the same day; the job must have the county-stamped complete plan set and an agent present or the inspection may be cancelled and a reinspection fee charged.
Which codes and exemptions should I review?
Lake County's 2026 Design Criteria require the 2025 California Building, Mechanical, Plumbing, Electrical, Fire, Energy (Title 24), and Wildland-Urban Interface codes. The criteria also publish local parameters including 90-mph wind speed for Risk Category II, a 5-psf snow load in Cobb and zero elsewhere, and local soil and seismic design criteria. The county's published CBC 105.2 guidance identifies minor exemptions including masonry or concrete walls no higher than 4 feet, other fences no higher than 7 feet, and retaining walls no higher than 4 feet measured from footing to top unless supporting a surcharge or impounding regulated liquids. The county also identifies qualifying driveway work on non-county-maintained roads and certain fire-replacement structures as exempt from an encroachment permit. Exemptions do not eliminate zoning, trade-permit, floodplain, or other applicable requirements.
