Do I need a permit to knock down a wall in my New Brunswick home?

Whether you need a permit to remove a wall in your NB home depends on one critical question: is it load-bearing? Removing a non-load-bearing partition wall generally does not require a building permit in New Brunswick. Removing or modifying a load-bearing wall absolutely requires a permit — and an engineer's assessment before work begins.

The reason the permit requirement hinges on structural status is straightforward: a load-bearing wall carries the weight of floors, roofs, or other walls above it down to the foundation. Remove it improperly — without installing the correct beam and adequate post supports — and you risk a partial structural collapse. Mistakes here are not cosmetic problems you can fix later; they can make a home uninhabitable and dangerous. The NB Building Code requires that any structural modification be supported by proper documentation (engineer's drawings or stamped design) and be inspected by the local building authority before concealment in drywall.

How do you know if a wall is load-bearing? It is not always obvious, and this is one of those situations where being wrong has serious consequences. General rules of thumb: walls that run perpendicular to floor joists are often load-bearing; walls that sit above a beam in the basement or crawl space are likely bearing walls; exterior walls are nearly always load-bearing. But in NB's older housing stock — the century homes in Fredericton's north side, the heritage rows in Saint John's South End, the post-war bungalows in Riverview — structural framing is not always predictable. A registered engineer or experienced general contractor can confirm load-bearing status by inspecting the framing from above (attic access) or below (basement). Budget $300-$700 for a structural engineer's site assessment and stamped drawings — money well spent before swinging a sledgehammer.

If the wall is confirmed non-load-bearing and no permit is required, there are still several practical considerations. You need to determine whether the wall contains electrical wiring, plumbing, or HVAC ductwork that must be rerouted. Knob-and-tube wiring is common in older NB homes and requires a licensed electrician to reroute safely — that work triggers a TSANB inspection even if the wall removal itself does not require a building permit. Removing a wall that contains a supply or return air duct may require HVAC rebalancing to maintain proper airflow through the space.

If the wall is load-bearing, the permit process requires submitting plans showing the proposed beam, post sizing, and connection details to your local building department. In Moncton, Saint John, Fredericton, and other incorporated municipalities, processing typically takes one to four weeks. The contractor then performs the work in stages: temporary shoring, beam installation, post placement, permit inspection, then drywall. The structural work itself — not including finishing — for a standard load-bearing wall removal with a 10-to-14-foot beam typically costs $3,000-$8,000 depending on span length, beam material (LVL or steel), and the complexity of the post-to-foundation load path.

Skipping the permit on a load-bearing wall modification creates serious downstream problems. When you sell your home, a buyer's home inspector will often identify improper structural modifications — sagging floors, out-of-level door frames, visible deflection in the ceiling — and the sale can collapse or require a significant price reduction. Insurance claims related to structural damage can be denied if unpermitted work contributed to the loss. The permit fee ($150-$400 for this scope of work) is a trivial expense compared to those risks. Hire a licensed contractor, pull the permit, and do it right the first time.
