How do I handle load-bearing walls in an NB kitchen renovation?

Never remove or modify a load-bearing wall without a structural engineer's assessment and a building permit — this is one of the most critical safety requirements in any New Brunswick kitchen renovation. Load-bearing walls carry the weight of the roof, upper floors, and the structure above down to the foundation. Removing one without proper support will cause sagging, cracking, and potentially catastrophic structural failure.

Many NB homeowners want to open up their kitchen to the dining or living room for a modern open-concept layout. In older NB homes built in the 1960s through 1990s, the wall between the kitchen and adjacent rooms is frequently load-bearing. Before you start planning an island or a wide-open sightline, you need to determine whether that wall is structural.

Identifying Load-Bearing Walls

There are clues that suggest a wall is load-bearing: it runs perpendicular to the floor joists (check from the basement), it sits directly above a beam or foundation wall in the basement, or it runs through the centre of the house parallel to the ridge line. Exterior walls are almost always load-bearing. However, these are guidelines, not certainties — only a structural engineer can definitively confirm whether a wall is load-bearing. An engineering assessment costs $300-$800 in New Brunswick and is money extremely well spent before you commit to a layout that depends on removing that wall.

Do not rely on a contractor's visual assessment alone. While experienced contractors can often identify load-bearing walls, the liability and safety stakes are too high for guesswork. If the wall is load-bearing and the engineer confirms it can be removed, they will design a beam and post system (typically an LVL — laminated veneer lumber beam or a steel I-beam) to carry the load. The engineer provides stamped drawings that your contractor follows and that the building inspector reviews.

The Process and Costs

Removing a load-bearing wall in an NB kitchen renovation involves several steps and professionals. First, the structural engineer designs the replacement support system ($300-$800 for the assessment and stamped drawings). Then you apply for a building permit through your municipality — Moncton, Fredericton, and Saint John have their own building departments, while rural areas go through Regional Service Commissions. Permit fees run $150-$300, and approval takes 1-3 weeks in cities or 2-5 weeks in RSC areas.

The construction work itself involves installing temporary shoring (temporary walls that hold the load while the permanent beam is installed), removing the existing wall, installing the engineered beam with proper bearing posts at each end, and then finishing the ceiling and floor where the wall was. Budget $5,000-$15,000 for a load-bearing wall removal depending on the span, beam material (LVL vs steel), and finishing work. A steel beam for a wider span costs more but allows a thinner profile that hides better in the ceiling.

Two inspections are required: a rough-in inspection after the beam and posts are installed but before the ceiling is closed up, and a final inspection after all finishing work is complete. Skipping the rough-in inspection is a code violation that could require you to tear out finished work so the inspector can see the structural connections.

Common Mistakes

The biggest mistake is skipping the engineer and permit to save money. This creates serious problems when you sell your home — a home inspection will flag unpermitted structural modifications, and buyers or their lenders may require proof of engineering or even remediation. The second most common mistake is assuming that a partial wall removal (creating a pass-through or half-wall) does not require engineering. Any modification to a load-bearing wall, even a small opening, needs professional assessment.
