How much do structural drawings cost when permitting a Toronto reno?

Structural drawings for a Toronto renovation typically cost between $1,500 and $6,000+, depending on the scope and complexity of your project.

For most mid-sized residential projects — think a load-bearing wall removal, beam installation, or underpinning a basement — you're looking at the $2,000–$3,500 range for a licensed structural engineer to produce stamped drawings. These are the drawings the City of Toronto Building Division requires before they'll issue a permit for any structural work.

It's important to understand what you're paying for. A structural engineer isn't just drawing lines — they're calculating loads, specifying beam sizes (LVL, steel, etc.), footing requirements, and signing off with their professional stamp (P.Eng.). That stamp is what makes the drawings legally acceptable to the City. Some homeowners try to skip this by using an architect's drawings alone, but for structural elements, Toronto Building typically requires the engineer's seal specifically.

Typical cost ranges by project type:

• Load-bearing wall removal / beam installation: $1,500–$2,500
• Basement underpinning: $2,500–$5,000
• Addition or new structure: $3,500–$8,000+
• Full home renovation with multiple structural changes: $5,000–$12,000+

A few factors will push your costs higher: older homes (pre-1950s) in neighbourhoods like The Annex or Cabbagetown often have non-standard framing that requires more investigation; projects requiring site visits add $300–$600 per visit; and if revisions are needed after the City's plan review, expect additional fees.

Toronto-specific context worth knowing: the City of Toronto Building Division (416-397-5330 / toronto.ca/building) requires drawings to be submitted digitally through their ePlans portal. Your engineer should be familiar with this process. Plan review for structural permits typically takes 10–20 business days for straightforward projects, but can stretch to 6–8 weeks if there are revision requests.

One common mistake homeowners make is hiring a contractor first and an engineer second. Do it the other way around. Get your structural drawings done before finalizing your contractor quotes — that way, everyone is bidding on the same stamped scope of work, and you avoid costly mid-project surprises when the inspector shows up.

Your best next step is to get 2–3 quotes from licensed structural engineers (P.Eng.) in Toronto. Many offer a free 15–30 minute consultation to scope the work. You can also find contractors experienced in permitted structural work through the Toronto Construction Network directory, where professionals are familiar with local permit requirements and can often recommend engineers they've worked with successfully.
