Summary
In the City of La Habra, Section 15.04.020 amends CBC Table 1505.1 and Section 1505.1.2 to require at least a Class B fire-retardant roof covering citywide on every new roof and on any existing roof where more than half the covering is replaced within a year, while flagging that buildings in a Fire Hazard Severity Zone or Wildland-Urban Interface face additional roofing requirements.
CBC Table 1505.1 is amended, by the deletion of Table 1505.1 and the addition of a new Table 1505.1 thereto, to read as follows: ... ... a. Unless otherwise required in accordance with the California Wildlife-Urban Interface Code or due to the location of the building within a fire district in accordance with Appendix D. CBC Section 1505.1.2 is amended, by the deletion of the entire section and the addition of a new section thereto, to read as follows: 1505.1.2. Roof coverings within all other areas other than Fire Hazard Severity Zones or a Wildland Urban Interface (WUI). The entire roof covering of every existing structure where more than 50 percent of the total roof area is replaced within any one-year period. the entire roof covering of every new structure, and any roof covering applied in the alteration, repair or replacement of the roof of every existing structure, shall be a fire-retardant roof covering that is at least Class B.
Full Breakdown
Section 15.04.020 replaces the standard CBC Table 1505.1 minimum roof covering table with a citywide requirement of Class B roofing for every construction type listed, Types IA through VB, and adds footnote (a) stating that requirement applies 'unless otherwise required in accordance with the California Wildlife-Urban Interface Code or due to the location of the building within a fire district in accordance with Appendix D.' The section then replaces CBC Section 1505.1.2 outright: for roof coverings 'within all other areas other than Fire Hazard Severity Zones or a Wildland Urban Interface (WUI),' the entire roof covering of every new structure, of every existing structure where more than 50 percent of the roof area is replaced within a one-year period, and any roof covering applied in the alteration, repair or replacement of an existing structure's roof, must be at least Class B fire-retardant.
The amendment is adopted as part of the 2025 California Building Code under Section 15.04.010, and it explicitly carves Fire Hazard Severity Zone and WUI-designated property out of the citywide Class B floor, sending those parcels to the state Wildland-Urban Interface Code and Appendix D fire-district rules for whatever higher roofing standard applies there instead.
Violations & Fines
Installing or replacing a roof covering below Class B outside a designated Fire Hazard Severity Zone or WUI area, or below whatever the state Wildland-Urban Interface Code requires inside one, is a Building Code violation subject to red-tag, permit denial or a corrective order from the city's building official, in addition to the general code enforcement remedies in Chapters 1.08 and 1.20.
