Structural Engineer Needed for Calgary Renovation?

Does the City of Calgary require a structural engineer for renovations? Find out when it's required and how Calgary Structural Engineers can help with your project.

Does The City Of Calgary Require You To Have A Structural Engineer During A Renovation?

Yes, in many cases the City of Calgary does require a structural engineer during a renovation, especially if you are modifying or removing load-bearing elements, altering the building envelope, or making structural changes to foundations, floors, walls, or roof systems. Even smaller projects may need structural input to comply with the Alberta Building Code or to obtain a permit.

At Calgary Structural Engineers, we specialize in residential renovations and ensure your plans meet city regulations and engineering standards—helping you avoid costly mistakes and delays.

When Is A Structural Engineer Required For Renovations In Calgary?

A structural engineer is typically required if your renovation involves any of the following:

  • Removing or altering load-bearing walls

  • Installing new beams, headers, or columns

  • Making changes to the foundation or basement structure

  • Adding second storeys, extensions, or sunrooms

  • Renovating a garage or supporting tall walls

  • Altering roof structure, trusses, or joists

  • Repairing structural damage or water-compromised framing

If your project affects the integrity or safety of a building’s structure, the City of Calgary will request stamped drawings from a licensed structural engineer. Permits won’t be approved without them.

Why Does Calgary Require Structural Engineers For Certain Renovations?

Calgary follows the Alberta Building Code and local bylaws to ensure that all renovations are safe, compliant, and won’t put homeowners, neighbors, or future occupants at risk. Structural engineers help:

  • Ensure load distribution is safe and sound

  • Identify potential weaknesses or failures

  • Provide detailed structural drawings for permit applications

  • Prevent unsafe DIY changes that could lead to collapse or fines

A structural engineer is the professional best equipped to assess if your changes could compromise the structural safety of your home.

What Happens If You Renovate Without A Structural Engineer Or Permit In Calgary?

Skipping a structural engineer or permit can lead to serious consequences:

  • Stop work orders issued by the City

  • Permit denial or retroactive application fees

  • Demolition or removal of completed work

  • Safety hazards for occupants

  • Difficulty with insurance claims or resale

If your project is later discovered to have unsafe or non-compliant work, you may be held liable. The city takes these violations seriously—and so should you.

Do All Renovations Need A Structural Engineer In Calgary?

Not all renovations require a structural engineer. Cosmetic updates—like painting, flooring, cabinetry, or minor drywall work—typically do not need structural review. However, if you’re unsure whether your renovation involves a structural element, it’s best to consult a professional. We offer initial consultations to assess whether engineering is required for your specific project.

How Do I Know If A Wall Is Load-Bearing?

Identifying a load-bearing wall isn’t always easy without structural knowledge. Some signs that a wall may be load-bearing include:

  • It runs perpendicular to ceiling joists

  • It’s located in the center of the home

  • It aligns with support beams in the basement

  • It has double top plates or steel beams above

However, the only way to be certain is by hiring a structural engineer to review the building plans or inspect the structure. Mistakenly removing a load-bearing wall can result in major damage.

Common Questions About Structural Engineers and Calgary Renovations

Q: Can a contractor or architect provide the same plans as a structural engineer? A: No. While contractors and architects are crucial to renovations, they are not licensed to provide structural engineering drawings or calculations. Only a professional engineer (P.Eng) can stamp and sign off on structural plans in Alberta.

Q: What does a structural engineering report include? A: A report typically includes structural analysis, calculations, load reviews, photos, stamped drawings, and a summary of findings and recommendations. These documents are required to submit a renovation permit to the City.

Q: How much does it cost to hire a structural engineer in Calgary? A: Costs vary depending on project complexity. For a basic wall removal assessment, fees may start around $600–$1,200. Larger projects such as basement additions or garage renovations may cost more. At Calgary Structural Engineers, we offer transparent pricing with no hidden fees.

Q: Will I need to hire both an architect and a structural engineer? A: Possibly. If your renovation involves significant design or aesthetic changes, an architect can draft the layout, while a structural engineer ensures the changes are structurally sound. We collaborate with architects and designers often.

Q: Can I use old house plans instead of hiring a structural engineer? A: Old plans may not reflect previous renovations or meet current building codes. The City of Calgary generally requires updated, engineer-stamped drawings for structural changes. Relying solely on outdated blueprints can result in permit denial.

Q: What if I only want to remove a small section of wall—do I still need engineering? A: Even a small section of wall could be load-bearing or serve a structural function. It’s best to get it checked before cutting into it. Calgary Structural Engineers can evaluate and confirm whether engineering is required.
