How much does a structural engineering drawing cost for a wall removal in Ontario?

For a single load-bearing wall in a typical house, a sealed structural drawing is usually a flat fee in the low hundreds of dollars — a small fraction of the overall renovation budget.

What's the most expensive part of removing a load-bearing wall?

Usually the construction itself — the beam, posts, footings, temporary shoring, drywall and finishing work — costs more than the engineering drawing. The drawing is what makes sure that construction money is spent correctly the first time.

Does a longer wall span cost more to engineer?

Often yes. Longer spans and walls carrying more floors above them typically need larger, sometimes steel, beams and more substantial posts and footings, which can affect both engineering complexity and construction cost.

How Much Does It Cost to Remove a Load-Bearing Wall in Ontario?

Updated September 2026 · Written by H. Malekghasemi, P.Eng.

Removing a load-bearing wall involves two very different kinds of cost: the engineering (a sealed structural drawing) and the construction (the beam, posts, footings, and finishing). Homeowners are often surprised to learn the engineering is usually the smaller of the two — but it's also the part that determines whether the construction is done safely and legally.

The two cost buckets

Item	What it covers
Structural drawing	Engineer's review, beam/post/footing sizing, sealed drawing for your permit application
Building permit fee	Set by your municipality, typically based on project value or a flat residential rate
Construction	Temporary shoring, demolition, new beam and posts, footings, drywall, paint, flooring transitions

For a single load-bearing wall in a typical house, the sealed drawing is usually a flat fee — our own OpenWall service, for example, prices this work at a fixed $129–$349 CAD depending on scope, rather than an hourly consulting rate. Construction costs vary far more widely depending on your contractor, finishes, and how much of the ceiling/floor needs to be opened up and repaired.

What actually drives the price up or down?

Span length — a longer opening generally needs a bigger (and pricier) beam.
What's above the wall — one storey of floor load is simpler than a wall carrying two floors plus a roof.
Beam material — engineered wood (LVL) is often more economical than steel, but steel may be required for longer spans or tighter ceiling depths.
Finishing scope — patching a small section of drywall costs far less than refinishing an entire open-concept ceiling.
Existing conditions — older homes, unknown framing, or previous unpermitted work can add investigation time on site.

Why the drawing is worth it regardless of price: an undersized beam is a problem that shows up months or years later — sagging, cracking, or a failed home inspection at resale. The relatively small cost of a proper structural drawing is what protects the much larger amount you're spending on construction.

Getting an accurate number for your project

Because construction costs depend so much on your specific contractor and finishes, the best way to get a real number is to have the structural drawing done first, then take it to contractors for firm quotes — they'll be pricing the exact beam and post sizes rather than guessing.
