Does replacing a wood stove in New Brunswick need an inspection?

Yes — replacing a wood stove in New Brunswick requires both a permit and inspection in most cases. This isn't just a swap-and-go job, even if you're putting the same size stove in the same spot.

Here's how it works in NB. Wood stove installations fall under the National Building Code of Canada 2020 (adopted in NB, mandatory for new applications as of May 1, 2025), which sets out clearance requirements, hearth pad dimensions, and combustion air provisions. More importantly, any solid fuel appliance installation — including a replacement — typically requires a building permit from your local authority. If you're in Fredericton, Moncton, Saint John, or another incorporated municipality, that's your city or town's building department. If you're in a rural or unincorporated area, it's your Regional Service Commission (RSC).

The inspection piece is handled by your municipality or RSC building inspector, who will check that clearances to combustibles are met, the hearth pad is properly sized, and the installation matches the manufacturer's specs. For the chimney and flue connection, inspectors want to see that the connector pipe, thimble, and chimney liner are all in good shape and appropriate for the new appliance — because a new stove may have different flue outlet sizes or temperature ratings than the old one.

One thing many homeowners miss: if the wood stove is your primary or supplemental heat source and you're in a rural property, your home insurance provider will almost certainly require documentation of a proper installation and inspection before they'll cover any fire-related claim. Skipping the permit can void your coverage — a very expensive lesson.

As for who does the physical installation, this is genuinely a DIY-capable job if you're mechanically competent and follow the manufacturer's installation manual to the letter. Many NB homeowners install their own wood stoves. But the permit and inspection are non-negotiable regardless of who does the work. The inspector is there to protect you, your family, and your home from chimney fires and carbon monoxide.

Practical cost context: building permits for a wood stove replacement are typically modest — often $50–$150 depending on the municipality or RSC. The inspection itself is included in that fee. If your chimney liner needs replacing to suit the new stove (very common when upgrading to a newer, cleaner-burning EPA-certified unit), budget $800–$2,500 for a stainless steel liner installation by a WETT-certified chimney professional.

Your next step: call your local building department or RSC before purchasing the new stove. Confirm whether a permit is required for a like-for-like replacement in your specific jurisdiction — rules can vary slightly — and ask what documentation they'll need at inspection (manufacturer's installation manual, clearance specs, and WETT inspection report are commonly requested).

You can also find chimney and hearth professionals in the New Brunswick Construction Network directory to help with the installation and any liner work needed.
