Summary
Apple Valley regulates construction in its wildfire-prone high desert terrain by adopting the state's building code for the wildland-urban interface wholesale. Chapter 8.23 of the Municipal Code adopts the 2025 California Wildland Urban Interface Code, including its appendices, by reference, so new construction in a fire hazard severity zone must meet the state's ignition-resistant building standards.
The California Wildland Urban Interface Code, 2025 Edition, including Appendices and its standards incorporated therein, as published by the California Building Standards, is hereby adopted and made part of this Chapter by reference.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 19 Update 1).
Full Breakdown
Rather than writing its own fire-hazard building rules, Apple Valley folds the state's wildfire building standard straight into its Municipal Code. 010, adopted by Ordinance No. ' That code governs ignition-resistant construction, roofing, vents, decking, and defensible-space building details for structures within a designated fire hazard severity zone, which covers much of the high desert terrain around the town. The adoption sits in Title 8, Buildings and Construction, alongside the Town's separately adopted California Building, Residential, Electrical, Plumbing, Mechanical, and Energy Codes, so a builder in a mapped fire hazard zone has to satisfy the WUI Code on top of those base codes, not instead of them.
220, governing two-unit residential projects under state SB 9 law, expressly bars ministerial approval on a site 'within a very high fire hazard severity zone, unless the site complies with all fire-hazard mitigation measures required by existing building standards,' showing the Town treats the fire hazard severity zone overlay as a real, mapped constraint on what can be built and where, not a formality.
Violations & Fines
Building without meeting the adopted WUI Code standards in a mapped fire hazard severity zone is enforced through the Building Division's plan-check and inspection process and through the Town's general Municipal Code penalty scheme. Under § 1.01.200, a violation is a misdemeanor punishable by up to a $1,000 fine and six months in County jail, or the Town may issue it as an infraction with escalating fines of $100, $200, and $500 for repeat offenses within a year.
