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.
Subject to the modifications and amendments contained in this chapter, the following primary and secondary codes are adopted and incorporated into the Solano County Code by this reference as if fully set forth... adopting by reference the Uniform Code for the Abatement of Dangerous Buildings. ... (b) Adopting administrative and nonbuilding regulations contained in the above referenced model codes, and further adopting by reference: (1) The Uniform Code for the Abatement of Dangerous Buildings, 1997 Edition, as published by the International Conference of Building Officials.
Official source re-checked September 8, 2026: no newer edition of the code had been published (publisher’s edition: current through Ordinance 1868, passed April 9, 2026).
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.
