Do I need a permit to install a wood stove in my garage in Fredericton NB?

Yes, you almost certainly need a permit to install a wood stove in your garage in Fredericton — likely more than one.

Installing a wood stove in a garage touches multiple regulatory areas at once: building permits, mechanical permits, and potentially fire code compliance. The City of Fredericton requires a building permit for the installation of solid-fuel-burning appliances, and the installation must comply with both the NB Building Code and the manufacturer's installation instructions, which are themselves based on CSA and ULC standards.

The permits you'll likely need in Fredericton include a building/mechanical permit from the City of Fredericton's Building Inspection department for the appliance installation itself, and a separate permit for the chimney or flue system. If you're adding any new electrical circuits to the garage at the same time (for lighting, a blower, or other upgrades), that work requires its own electrical permit and inspection by a licensed electrician.

The wood stove installation must meet specific clearance requirements — from combustible walls, the ceiling, and the floor — as outlined in the NB Building Code and the appliance's ULC listing. In a garage, the floor is typically concrete, which simplifies the hearth pad requirement, but wall clearances are critical, especially if your garage has wood-framed walls with vinyl or LP SmartSide cladding. Minimum clearances to combustibles are typically 18 inches on the sides and rear for a listed appliance with a proper heat shield, but this varies by the specific stove model and its ULC listing — the manufacturer's manual governs.

The chimney installation is where most garage wood stove projects get complicated. You'll need a properly insulated Class A double-wall or triple-wall chimney pipe rated for solid-fuel appliances — not single-wall stovepipe for the full run. The chimney must extend at least 3 feet above the roof penetration point and at least 2 feet above any part of the roof within 10 feet horizontally. In a garage with a low-pitched roof, meeting that height requirement sometimes means a taller chimney than homeowners expect. The roof penetration must be flashed and sealed properly, which in NB's climate means a quality flashing collar that can handle freeze-thaw cycling.

For an attached garage in Fredericton, there's an additional layer of complexity. The fire separation between your garage and the house — required to be a 45-minute fire-rated assembly under the NB Building Code — cannot be compromised by the wood stove installation. Any chimney penetration through a common wall or ceiling must be properly fire-stopped. A wood stove in an attached garage also raises questions about combustion air supply and carbon monoxide management that a building inspector will want addressed.

Practically speaking, here's what to do:

Call the City of Fredericton Building Inspection department directly at 506-460-2068 before purchasing anything. Describe your garage (attached or detached, size, construction type) and the appliance you're considering. They'll tell you exactly which permits are required and what documentation you'll need — typically a site plan showing the garage, a floor plan showing stove placement and clearances, and the appliance's ULC listing documentation.

Hire a WETT-certified (Wood Energy Technology Transfer) installer for the actual installation. WETT certification is the industry standard for solid-fuel appliance installation in Canada, and many insurance companies require a WETT inspection certificate before they'll extend coverage for a wood-burning appliance. Your homeowner's insurance provider should be notified of the installation regardless — some policies require prior approval.

This is firmly in professional territory. Between the permit requirements, chimney engineering, clearance calculations, and insurance implications, a wood stove installation is not a DIY project in NB regardless of how handy you are.
