Summary

Unincorporated Yuba County must review a complete small residential rooftop solar application within three working days and issue the permit, then consolidate all inspections into one final visit, under County Code Chapter 10.10.

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

(b)The review and approval of required documents, where deemed complete, shall be completed within three working days of receipt and the permit issued.(c)Review of the application shall be limited to the Building Official's review of whether the application meets local, state, and federal health and safety requirements as outlined in the standard plans and checklists.(d)If an application is deemed incomplete, a written correction notice detailing all deficiencies in the application and any additional information or documentation required to be eligible for expedited permit issuance shall be sent to the applicant for resubmission.(e)It shall be the duty of the holder of the building permit or their duly authorized agent to notify the Building Official when work is ready for inspection. Inspections will generally be performed the following business day after the request has been received, except that Inspections may be performed the same business day when requested through the County's automated IVR system no later than 7:00 a.m. It shall be the duty of the permit holder to provide access to and means for inspections of such work that are required by this Code.(f)Inspection for small residential rooftop solar energy systems eligible for expedited review shall be consolidated into one (1) inspection which shall be performed by the Building Department. The one inspection shall be performed as a final inspection.

Full Breakdown

Chapter 10.10, adopted to comply with the state Solar Rights Act and AB 2188, sets up an expedited permitting track for small residential rooftop solar systems (10 kW AC or 30 kWth or smaller) on one- or two-family homes in unincorporated Yuba County. Section 10.10.330(b) requires the County to complete review and issue the permit within three working days once the application is deemed complete. Section 10.10.330(f) consolidates every required inspection into a single final inspection, unless a separate fire inspection is needed because no agreement exists with the local fire authority.

Violations & Fines

An application that's incomplete or fails the eligibility checklist doesn't get penalized: it's routed to the standard, non-expedited building permit process, with a written correction notice detailing what's missing.
