Keep Your Family Warm and Safe—No Matter What

Generally, no. Denver's building code, aligned with Colorado's Regulation No. 4, prohibits new open-hearth, wood-burning fireplaces in new residential construction and most major remodels within the Denver metro nonattainment area—a rule that dates back to the city's response to its winter "brown cloud" inversions. New homes are built with gas fireplaces or, in some cases, EPA-certified wood or pellet appliances instead of a traditional masonry hearth. If your home already has an existing wood-burning fireplace, you can keep using it, but you generally can't add a brand-new one where none existed.

Yes, and it's one of the more common wood-related projects in Denver's older housing stock. Swapping an aging, inefficient masonry fireplace for a certified wood insert or freestanding stove is allowed even in neighborhoods where a brand-new wood-burning unit wouldn't be. Depending on the insert model, liner work, and hearth clearance requirements, homeowners in Denver typically budget somewhere in the $4,000 to $7,500 range for this kind of retrofit. A local hearth dealer can confirm whether your existing chimney and flue can accommodate a liner without major masonry work.

During winter inversions, the Colorado Department of Public Health & Environment can issue high pollution advisories that restrict the use of older, uncertified wood-burning stoves and fireplaces across the Denver metro area. EPA-certified appliances are typically treated more favorably under these rules than open-hearth fireplaces or pre-1990s stoves, which is one more reason an older uncertified unit is worth upgrading if you plan to actually burn wood on a regular basis. Check current advisory status before burning on any still, cold winter day.

Denver itself sits well out on the plains side of the Front Range, so most local wood comes from the foothills and mountains to the west. Cutting permits through Arapaho-Roosevelt National Forest run $5 to $20 per cord during the May-to-October season, and ponderosa pine, aspen, pinyon, and juniper are the species you'll typically find. If you'd rather not cut your own, several regional suppliers deliver split, seasoned cordwood into the metro area, usually priced by the species and whether it's kiln-dried or air-dried.

For most Denver households, gas wins on practicality: natural gas service is widely available through Public Service Company of Colorado (Xcel Energy), a new gas fireplace is legal to install anywhere in the city, and it doesn't carry the burn-day restrictions that apply to wood. Wood still has real advantages—it works without electricity during an outage, and it's the more affordable fuel if you're already set up to source or cut your own. But given Denver's air quality rules, a new build or remodel in the city is almost always better served by a gas unit, with a wood insert reserved for homes that already have an existing masonry fireplace to retrofit.

Pellet stoves burn cleaner than open-hearth wood fireplaces and are exempt from mandatory burn restrictions in many other Colorado jurisdictions, but Denver's nonattainment status and building code treat new solid-fuel appliances conservatively across the board, including pellet units in new construction. Gas and electric remain the more straightforward legal path for a brand-new installation inside city limits. If pellet heat is a priority for you, ask a local dealer about the specific permitting status for your address and property type before you commit to a unit.

It compounds the issue. Denver's summer and fall air quality is increasingly affected by wildfire smoke drifting in from fires across the Rockies and the broader West, on top of the metro's existing winter inversion problem. That combination is part of why regional air quality regulators have been conservative about adding new wood-burning sources to the airshed, and it's worth factoring in if you're deciding between wood and a cleaner-burning alternative for year-round air quality in your home.

Yes—once you get outside the Denver-Julesburg nonattainment boundary and up into the foothills, wood heat is far more common and far less restricted. Mountain communities and exurban properties near the Arapaho-Roosevelt National Forest, where ponderosa pine and aspen are abundant and homes are more likely to lose power during winter storms, rely on wood stoves as genuine primary or backup heat. If you own a cabin or second home in that kind of setting, the calculus is very different than it is inside Denver city limits.

For most Denver homes, a direct-vent gas fireplace or insert is the straightforward legal replacement, and it pairs well with the widely available Public Service Company of Colorado natural gas network. Electric fireplaces are another option worth considering for supplemental heat or ambiance in rooms where venting isn't practical, running on Public Service Company of Colorado's residential rate of about 15 cents per kWh. A local dealer can walk you through which option fits your specific fireplace opening, chimney condition, and budget.

An insert does two things: it seals the chimney completely, so you stop losing air you already paid to heat, and it radiates warmth into the room through the firebox and glass. Most add a heat-exchange fan that pulls cool room air underneath, wraps it around the hot firebox, and pushes it back out warm. Your home is more efficient before you've even lit the first fire.

Fireplaces are like icebergs—bigger behind the wall than in front of it. Replacement means removing the surrounding tile or stone (the finish material laps onto the fireplace face), pulling the old unit, setting the new one in the same enclosure, and re-finishing the wall. A hearth professional can determine what's behind your wall without demolition during an in-home preview.

If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.

It's a visit where a hearth professional measures your space, confirms the model you picked actually works in your home, and walks the specs—framing, gas line, venting, finish work—before anything is ordered. Some details you just can't know until you see the house. Never make a down payment without one; it's the single most-skipped step that burns buyers.
