Denver is mostly urban and not in mapped Wildland-Urban Interface (WUI) zones, but western foothill-adjacent neighborhoods and open space buffers follow Denver Fire Department defensible space guidance aligned with Colorado's WUI code.
Denver proper lies primarily on the plains and is not within Colorado's formally mapped WUI zones like Boulder, Jefferson, or Douglas counties. However, Denver Fire Department enforces defensible space guidance in areas adjacent to open space corridors (Bear Creek, Highline Canal, Platte River greenway) and western edge neighborhoods near Green Mountain and Lakewood. Recommended practices follow Colorado State Forest Service guidelines: Zone 1 (0-5 feet from structure) — noncombustible, no vegetation or mulch; Zone 2 (5-30 feet) — 'lean, clean and green' with low-growing, well-irrigated plants and pruned trees; Zone 3 (30-100 feet) — reduced fuels, tree spacing 10+ feet. 2018 IWUIC (International Wildland-Urban Interface Code) is not adopted in Denver but Class A roof coverings are standard. Denver Fire Department open-burning restrictions apply year-round; seasonal stage 1/2 fire restrictions may trigger during drought. Metro Denver seasonal burn ban Nov 1 - Mar 31 under CDPHE Regulation 4.
Open burning during restrictions: $150 to $999 per DRMC §16-29. Defensible space: advisory in most of Denver, enforced only in conditional use cases. Class A roof at re-roof: code requirement.
