Wood stove permits in Longmont.
Get the permit from Longmont Building Services.
Inside Longmont city limits, Building Services at the Development Services Center, 385 Kimbark Street, issues building permits. The city’s permits page lists ‘fireplace or gas log installation’ and any change to gas or mechanical systems as work needing a permit, and asks residents to contact Building Services when unsure. It does not name wood stoves or inserts, so ask which permit covers your stove, insert or chimney liner. Longmont’s 2024 residential code defines a wood stove, including a fireplace insert, as one that complies with the state air-quality commission’s rules, so bring the model’s certification. Addresses outside city limits in Boulder or Weld County go to the county instead.
City of Longmont: PermitsLongmont enforces its own high-pollution-day ban.
CDPHE lists Boulder County among the seven metro Denver counties where indoor burning is restricted on Action Days from November through March; EPA-certified stoves, pellet stoves and Colorado-approved masonry heaters are exempt. Longmont has its own ordinance too: Sec. 16.44.020 makes it unlawful to operate a solid fuel-fired heating device on a state-declared high-pollution day without a city exemption, allows three hours to burn down an existing fire, and puts the duty on owners to know when a day is declared. Check the daily status rather than this guide.
Longmont Code Ch. 16.44 Burning RestrictionsWant to burn on high-pollution days? Ask about the city exemption.
Longmont Code Sec. 16.44.030 lets the city manager or designee grant an exemption on a sworn statement, including one that a Phase III certified device, or one meeting the state’s strictest wood-stove emission standard, was installed to code. The exemption lasts one year, must be renewed with a new statement, can be revoked for excessive smoke, and the certificate must be posted near the main entrance where it is visible from the street.
Longmont Code Ch. 16.44 Burning RestrictionsHiring an installer? Longmont licenses contractors.
Longmont Code Ch. 16.48 says no one may work as a contractor in the city without a license from the chief building official. The mechanical license covers heating and venting work, and a separate D-3 specialty license covers masonry and fireplaces. A homeowner working on the house they live in is not treated as a contractor. Ask any installer which Longmont license they hold before you sign.
Longmont Code Ch. 16.48 Building Contractor’s LicenseDesignated landmark? Get a Certificate of Appropriateness.
Longmont says no exterior alteration is permitted on a designated historic landmark without a Certificate of Appropriateness from the Historic Preservation Commission, and asks owners to contact staff before any exterior work. A new chimney, exterior flue or roof penetration on a landmark is the kind of change to raise with the city’s historic preservation planner before the building permit.
Longmont Certificate of Appropriateness applicationThis is a planning guide, not a permit determination. The local authority and your installer must confirm current requirements for your property and appliance. We have not verified project-specific approvals or fees.

What to ask a Longmont installer.
- Do you hold a City of Longmont contractor license (mechanical or D-3 masonry and fireplaces), and will you apply for the permit?
- Does this stove meet the state emission standard Longmont uses to define a wood stove, and would it qualify for a Sec. 16.44.030 exemption?
- Is my address inside Longmont city limits and in Boulder County, or in the Weld County part or unincorporated land?

Longmont wood stove installation FAQs.
Can I burn my wood stove in Longmont during a power outage on a high-pollution day?
Longmont Code Sec. 16.44.040 makes a power outage, natural-gas interruption or temporary equipment failure you did not cause an affirmative defense to a high-pollution-day charge. That is a defense, not a permit to burn. Separately, the state exempts EPA-certified stoves from Action Day limits, so a certified stove avoids most of the question.
Does Longmont have its own burning rules, or just the state’s?
Both. CDPHE lists Boulder County in the metro Denver Action Day area. Longmont’s Chapter 16.44 separately bans operating a solid fuel-fired heating device on a state-declared high-pollution day without a city exemption, allows three hours to burn down, and bans burning coal in any form.
Can I install the stove myself in Longmont?
Longmont’s contractor-licensing chapter says a homeowner working on the house they live in is not treated as a contractor, so no contractor license is needed for that. You still need the city permit and inspections. Contact Building Services at 385 Kimbark Street to confirm which permit covers a wood stove or insert.
