15.50.010 Waiver of Class A roofing requirements.

A waiver of the Class A roofing requirement specified in Section 1505.1 of the 2022 Edition of the California Building Code and the use of Class B or C roof assemblies may be applied for only when an addition to an existing structure will not increase the combustible roof area by more than 25 percent. If a waiver of this requirement is desired, an application for waiver shall be filed with the building official.

The building official shall determine if a waiver is appropriate. An appeal of the building official’s decision to deny a waiver may be made to the planning commission if a written notice of the appeal is filed with the city clerk within 10 days of the date of the building official’s decision. The decision of the planning commission to affirm the building official’s denial of a waiver may be appealed to the city council if a written notice of the appeal is filed with the city clerk within 10 days of the date of the commission’s decision. The decision of the city council shall be final. [Ord. 389 § 11, 2023; Ord. 368 § 11, 2019.]

15.50.020 Reroofing an existing structure.

The Class A roofing requirement specified in Section 1505.1 of the 2022 Edition of the California Building Code shall not apply to the partial reroofing of an existing structure where the reroofing repairs, replaces, or overlays less than 25 percent of the roof area of the structure. If the reroofing repairs, replaces, or overlays more than 25 percent but less than 50 percent of the roof area of the structure, this requirement shall apply, but an application for a waiver of this requirement may be filed with the building official. The building official shall determine if a waiver is appropriate. An appeal of the building official’s decision to deny a waiver may be made in accordance with CMC 15.50.010. No application for a waiver may be filed or granted if the reroofing repairs, replaces, or overlays 50 percent or more of the roof area of the structure. [Ord. 389 § 11, 2023; Ord. 368 § 11, 2019.]
