Summary
Solano County requires inspections at every stage of a permitted project and locks the final inspection under an amended California Building Code Sec. 110.3.10: it cannot pass until all electrical, plumbing, mechanical, floor covering, painting, and required landscaping work is complete and the site is clean.
Final Inspection shall be made after final grading and the building is completed and ready for occupancy. This shall mean all work required by the building permit, all electrical, plumbing and mechanical complete and ready for occupancy, as well as all floor covering installed and painting completed, as well as any required exterior landscaping complete with house, sidewalks, and streets cleaned.

Full Breakdown
Sec. 3-10(b) directs the county to "require inspections, made by various county departments, for all places in the county to ascertain if all provisions of this chapter and all other applicable ordinances of the county have been complied with prior to the issuance of such a permit," giving the Building Official broad authority to coordinate inspections across departments during construction. The county then locally amends the state's final inspection standard: Sec. " No certificate of occupancy can issue until this final inspection, and the certificate itself is separately required under Sec.
3-17 before any building can be occupied. For projects relying on an on-site well, spring, or surface water supply, Sec. 5, per Sec. 3-10(a), including the power to cite or arrest for noncompliance discovered during an inspection.
Violations & Fines
Occupying or using a building before it passes final inspection and receives a certificate of occupancy is treated as a public nuisance under Sec. 6.3-17 and is an infraction under Sec. 6.3-09(a) and (e), with each additional day of noncompliance after citation constituting a separate violation. Sec. 6.3-09(f) makes the violator liable for the county's costs of correction, abatement, and prosecution on top of any infraction penalty, and remedies are cumulative under Sec. 6.3-09(c), so citation and nuisance abatement can proceed together.
