Colusa, Cal., Code of Ordinances ch. 22 § 22-6

(a) Building Code requirements. A building proposed for conversion, and each unit within the building, shall comply at a minimum with all applicable Building Code standards in effect at the time of the last alteration, repair, relocation, or reconstruction of the building, necessitating compliance with the Building Code, or, if none, at the time of first construction.
(1) No building shall be permitted to be converted to condominium ownership unless the building was constructed and subject to a building permit issued under the provisions of the 1952 Uniform Building Code, or subsequently adopted Uniform Building Code, unless it is found by the appropriate authority that the building constructed prior to 1952 is decent, safe, and sanitary based upon property report review by building inspector.
(2) No building constructed after the effective date of this ordinance shall be permitted to be converted to condominium ownership unless the building was constructed in full compliance with all applicable building codes and the development standards applicable to new condominium construction, in effect at the time of the last alteration, repair, relocation, or reconstruction of the building, or, if none, at the time of first construction.
(b) Building inspection. After reviewing the property report required and after inspecting the structures within the project when deemed necessary, the building inspector shall identify and make available to the planning commission and board all items evidenced by such reports or inspection to be in noncompliance with applicable building and housing codes or to be hazardous to life, health or safety of any occupant of the units within the project or the general public. All such items shall be corrected to the satisfaction of the building inspector. An appropriate fee to cover the cost of the building inspector's review and inspection may be collected.
(c) Performance bond. If the proposed project does not comply with the provisions relating to utilities, personal safety and Building Code compliance, or if the building inspector identifies items to be corrected any use permit issued pursuant to this part shall require the developer to furnish a performance bond or other means of security approved by the city attorney, in an amount to be determined by the building inspector to be the reasonable estimated cost to bring the project into compliance with said codes and to make all necessary repairs. The bond shall run in favor of individual purchasers and the association, and the bond shall provide for reasonable attorney's fees in the event of default by the principal.
(d) Utilities.
Gas. Each condominium shall have a separate gas service where gas is a necessary utility. If this provision places unreasonable economic burden on the applicant, the appropriate authority may approve an alternative.
