Why Denver Has Some of the Strictest Fire Regulations in the State

Denver maintains 204 local ordinances across all categories, and 4 of those deal specifically with fire regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Denver falls on the strict-to-permissive spectrum compared to other cities.

Propane Storage

Denver Fire Code DRMC §10 adopts the International Fire Code Chapter 61 for liquefied petroleum gas. Residential cylinders are capped at 25 gallons aggregate water capacity outside, and indoor storage is sharply limited with permits required above small thresholds.

Key details: Code basis: DRMC §10 + IFC 61. Residential limit: 25 gal water capacity. Indoor BBQ tank: Prohibited. Permit office: Denver Fire Prevention.

Fire Code violations carry administrative penalties up to several thousand dollars per offense, mandatory abatement, and possible criminal misdemeanor charges. Fire inspectors can red-tag noncompliant tanks and seize illegally stored LP-gas.

This is one of the stricter rules in Denver's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Fireworks

Denver bans ALL fireworks, including consumer-grade sparklers and fountains. DRMC §39-4 imposes fines up to $999 per violation. The ban applies year-round.

Key details: All Fireworks Banned: Yes – including sparklers and fountains. Fine: Up to $999 per violation. Code Section: DRMC §39-4. Enforced By: Denver Fire Department. Year-Round: Ban applies 365 days a year.

Fines up to $999 per violation. Repeat or egregious violations can result in criminal charges.

Compared to other cities, Denver takes a harder line on fireworks. The enforcement and penalty structure reflects that.

Outdoor Burning

Denver bans open wood burning year-round without a permit. Propane and natural gas fire features are allowed. The metro area also bans all wood burning Nov 1–Mar 31.

Key details: Wood Burning: Banned year-round without DFD permit. Metro Winter Ban: Nov 1–Mar 31 (7-county area). Propane/Gas Fires: Permitted. Fine: Up to $999. Enforced By: Denver Fire Department.

Fines up to $999 for unauthorized open burning.

This is not one of those rules that cities tend to ignore. Denver actively enforces its outdoor burning requirements.

Fire Pit Rules

Wood-burning fire pits illegal in Denver. Only gas-fueled (propane/natural gas) fire features permitted. Cooking devices (gas/charcoal grills) exempt from permit requirement but charcoal banned on balconies.

Key details: Wood Fire Pits: Prohibited. Gas Fire Pits: Allowed. Cooking Exemption: Grills exempt from permit. Balcony Charcoal: Prohibited.

Fines up to $999 for unpermitted solid-fuel burning in fire pits or chimineas.

This is one of the stricter rules in Denver's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

The Bottom Line

Denver is tougher than many cities when it comes to fire regulations. Out of the 4 rules covered here, 4 are rated strict. If you are a homeowner, renter, or business owner in Denver, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

These rules come from Denver's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
