Summary

Solano County has adopted the 1997 Uniform Code for the Abatement of Dangerous Buildings by reference as part of Chapter 6.3, giving the Building Official authority to declare a structure dangerous and order it repaired or removed. Occupying a building without a certificate of occupancy is itself declared a public nuisance subject to abatement.

City-specific rules exist: Vallejo, Vacaville, and Fairfield have their own property blight rules that differ from Solano County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Full Breakdown

Sec. 3-03(a) adopts the California Building Standards Code, 2025 Edition, and "adopt[s] by reference the Uniform Code for the Abatement of Dangerous Buildings," and Sec. 3-03(b)(1) makes this explicit by naming "The Uniform Code for the Abatement of Dangerous Buildings, 1997 Edition, as published by the International Conference of Building Officials" as one of the secondary codes incorporated into the Solano County Code. That uniform code supplies the county's mechanism for identifying buildings that are structurally unsafe, fire hazards, or unfit for human occupancy and ordering their repair, vacation, or demolition.

The county backs this with its own occupancy rule: Sec. " Enforcement authority sits with the Building Official, who under Sec. 5. Sec. 3-10(b) further requires county departments to inspect properties to confirm compliance with the chapter and other applicable county ordinances before any permit issues. The Department of Resource Management is required by Sec. 3-04 to keep copies of the adopted dangerous-building code on file for public review, and any newly adopted state code changes must go through a Board of Supervisors hearing under Sec. 3-08 before amendment.

Violations & Fines

Maintaining a building in violation of the adopted dangerous buildings code, or occupying a structure without a certificate of occupancy, is an infraction under Sec. 6.3-09(a) and (e), with each additional day of noncompliance after citation treated as a separate violation carrying the same penalty. Sec. 6.3-09(f) makes the responsible party liable for the county's costs, expenses, and disbursements in correcting, abating, and prosecuting the violation, in addition to any infraction fine. Remedies under the chapter are cumulative under Sec. 6.3-09(c), so the county is not limited to a single enforcement tool against a dangerous or unpermitted structure.

Frequently Asked Questions

What code governs dangerous or unsafe buildings in unincorporated Solano County?
The county has adopted the Uniform Code for the Abatement of Dangerous Buildings, 1997 Edition, by reference under Sec. 6.3-03(a) and (b)(1), giving the Building Official the authority granted by that uniform code to order repair, vacation, or demolition of unsafe structures.
Can I occupy a building in Solano County without a certificate of occupancy?
No. Sec. 6.3-17 states that no building may be used or occupied without a certificate of occupancy, and doing so constitutes a public nuisance that the county will abate, regardless of whether the structure is otherwise safe.
Who enforces dangerous building rules in the county?
The Building Official and designated deputies enforce Chapter 6.3, including the adopted dangerous buildings code, and are authorized under California Penal Code Section 836.5 to issue citations or make arrests for violations, per Sec. 6.3-10(a).
What can the county do if I don't fix a cited violation?
Because remedies under Sec. 6.3-09(c) are cumulative, the county can pursue infraction citations, cost recovery for abatement and prosecution under Sec. 6.3-09(f), and separate abatement action for the dangerous condition all at once, rather than being limited to one enforcement path.
