Verified from official government sources
BBQ & Propane Rules
Boulder adopts the International Fire Code under Boulder Revised Code Title 10 Chapter 8 (Fire Code). IFC Section 308.1.4 prohibits charcoal burners, gas grills, and other open-flame cooking devices on combustible balconies or within 10 feet of combustible construction in multifamily buildings — a heavily enforced rule given Boulder's dense student housing near CU Boulder. Exceptions exist for sprinklered balconies, one- and two-family dwellings, and 1-pound (2.5 lb water capacity) camping propane cylinders. Inside the expanded WUI (effective Aug. 1, 2025) additional restrictions apply.

Heavy RestrictionsSmoker Rules
Boulder has no smoker-specific ordinance; offset, pellet, kamado, and wood-fired smokers fall under the general IFC 308 framework adopted in BRC 10-8-2 plus Boulder's burn-restriction system. Single-family backyard smokers are allowed under normal conditions but charcoal and wood-burning smokers on multifamily balconies are barred by IFC 308.1.4. The Colorado Regional Air Quality Council declares winter High Pollution Action Days that restrict residential wood burning along the Front Range, including wood smokers. Inside the expanded WUI, additional ignition-source restrictions apply from August 1, 2025.
