Yes — in almost every case you need a building permit from the City of Ottawa to install a wood stove, wood-burning fireplace insert, or new chimney. A solid-fuel appliance permit in Ottawa typically costs about $180 to $350 in 2026, and the installation itself usually runs $4,000 to $9,000 for a stove, hearth pad, and insulated chimney system. The permit triggers a City inspection that confirms your appliance meets the Ontario Building Code and CSA B365 installation standard for clearances, hearth protection, and venting. On top of the permit, most Ontario home insurers will require a WETT (W...
The City of Ottawa requires a building permit for the installation of any solid-fuel-burning appliance — that includes freestanding wood stoves, pellet stoves, wood-burning fireplace inserts, masonry heaters, and outdoor wood-fired boilers — as well as for constructing, lining, or replacing a chimney. A permit is also required when you convert an existing decorative fireplace into a working wood-burning unit, or when you re-line an old masonry chimney to accept a modern insert. The narrow exceptions are true like-for-like repairs and simple maintenance: replacing a broken gasket, cleaning the flue, or swapping a damaged stove pipe section within an already-approved installation generally does not need a permit. Moving an existing stove to a different room, changing the appliance model, or altering the venting path always does. If you are unsure, call the City's building code services line before ordering equipment — an unpermitted install is far more expensive to correct than to permit up front.
Pellet stoves are still solid-fuel appliances and require a building permit in Ottawa. Gas fireplaces and gas inserts follow a separate path: they must be installed by a TSSA-registered contractor holding a G2 or G1 gas licence, and the gas work is certified under TSSA rules rather than a City solid-fuel permit, although structural or venting alterations can still need a building permit.
A City of Ottawa building permit for a wood stove or fireplace insert generally falls in the $180 to $350 range in 2026, based on the City's minimum permit fee for small residential alterations. If your project also involves structural framing changes — cutting a new roof penetration through trusses, building a chase, or reinforcing a floor for a heavy masonry heater — the fee climbs with the value of the work. The appliance itself is the bigger number: a quality EPA-certified wood stove costs roughly $2,000 to $4,500, an insulated stainless-steel Class A chimney system adds $1,500 to $3,500 depending on height and the number of offsets, and a non-combustible hearth pad or tile hearth runs $400 to $1,500. Labour for a straightforward main-floor installation is typically $1,200 to $2,500. All in, most Ottawa homeowners spend $4,000 to $9,000, with two-storey chimney runs, cathedral ceilings, and stone surrounds pushing projects past $12,000.
The chimney is where budgets get blown. A short exterior run through a wall is far cheaper than a straight vertical run through two floors and a cathedral roof, which needs extra support boxes, firestops, and flashing. Get the chimney route settled before you compare quotes.
Ottawa building inspectors verify that a wood stove is installed exactly as its certification label and manufacturer's manual specify, under CSA B365. The most common failure is clearance to combustibles — the minimum distance from the stove body and the stove pipe to walls, trim, furniture, and ceilings. Uncertified or older stoves default to very generous clearances (often 48 inches to a combustible wall), while modern EPA-certified units with factory heat shields can sit as close as 6 to 12 inches. Approved wall shields with a continuous 1-inch air gap and open top and bottom can legally reduce clearances, but only when built to spec. Inspectors also confirm the hearth pad extends far enough in front of and beside the loading door, that it meets the required thermal resistance, that the chimney terminates high enough above the roofline for proper draft, and that the flue diameter matches the appliance. Photograph the appliance's certification label before drywall or stonework goes in — inspectors need to read it.
A building permit satisfies the City; a WETT inspection satisfies your insurer. Most Ontario home insurance companies will not bind or renew a policy on a house with a wood-burning appliance without a current WETT report, and many require one within 30 days of the install being completed. A WETT-certified inspector reviews clearances, chimney condition, hearth protection, and appliance certification, then issues a written report. In Ottawa, a Level 1 WETT inspection runs about $200 to $400 in 2026; a more invasive Level 2 inspection on an older or hidden system can cost $400 to $700. You must also declare the wood stove to your insurer — an undeclared solid-fuel appliance is a common reason claims get denied after a chimney fire. Ask your installer whether they hold WETT certification themselves, since many Ottawa hearth companies bundle the inspection report into the installation price. Before signing anything, it's worth reviewing how to check a contractor before hiring in Ottawa so you can confirm certifications independently.
Insurers increasingly ask for proof of yearly chimney cleaning. A professional sweep in Ottawa costs roughly $175 to $300, and creosote buildup from burning unseasoned wood is the leading cause of chimney fires in eastern Ontario homes.
Ontario does not license wood stove installers the way it licenses electricians and gas fitters, so the burden of vetting falls on you. Look for a company whose technicians hold current WETT certification, carries general liability insurance and WSIB coverage, and states in writing that it will pull the City of Ottawa building permit and book the inspection. Ask for the exact make and model of the appliance, the brand and grade of the chimney system, the planned clearances, and whether the quote includes the hearth pad, roof flashing, and disposal of any old unit. Be direct about who is responsible if the inspection fails. Three written quotes on identical scope will show you quickly who is thorough and who is guessing. If a contractor offers to install "under the radar" without a permit to save you a few hundred dollars, walk away — that shortcut can void your insurance and stall a future home sale when the buyer's inspector flags an uncertified appliance.
Yes. The City of Ottawa requires a building permit to install any solid-fuel appliance, including wood stoves, pellet stoves, fireplace inserts, and new or re-lined chimneys. Expect a permit fee of roughly $180 to $350 in 2026, plus a City inspection confirming the install meets the Ontario Building Code and CSA B365.
Most Ottawa homeowners pay $4,000 to $9,000 in 2026 for a complete wood stove installation. That typically breaks down to $2,000–$4,500 for an EPA-certified stove, $1,500–$3,500 for an insulated Class A chimney, $400–$1,500 for a hearth pad, and $1,200–$2,500 in labour. Complex two-storey or cathedral-ceiling chimney runs can exceed $12,000.
The City does not require WETT certification, but nearly every Ontario home insurer does. A Level 1 WETT inspection in Ottawa costs about $200 to $400 in 2026, and a Level 2 inspection on an older or concealed system runs $400 to $700. You must also declare the appliance to your insurer or a future claim may be denied.
There is no provincial licence requirement, so a homeowner can technically do the work, but you still need the City building permit and the installation must pass inspection and meet CSA B365 clearances. Insurers are also far more likely to demand a WETT report — and sometimes a professional install — before covering a DIY solid-fuel appliance.
Clearances come from the appliance's certification label and manual. Modern EPA-certified stoves with factory heat shields can sit 6 to 12 inches from a combustible wall, while uncertified or older stoves often require up to 48 inches. Approved wall shields with a continuous 1-inch air gap can reduce those distances when built exactly to spec.
Simple residential solid-fuel permit applications are usually issued within about 5 to 10 business days in Ottawa, assuming your drawings and appliance specifications are complete. Book the final inspection once the install is done and before you close in any surrounding stonework or drywall.
