Who Approves Residential Structural Drawings in Calgary?

Who Approves Residential Structural Drawings in Calgary?

In Calgary, residential structural drawings must be approved by the City of Calgary’s Planning & Development department. This process involves reviewing the structural design to ensure compliance with the Alberta Building Code, zoning bylaws, and local regulations. Depending on the project’s complexity, other authorities or third-party professionals may also be involved in the review and approval process. Here’s everything you need to know.

Understanding the Role of the City of Calgary in Approvals

Calgary Building Services and Permit Approvals

The City of Calgary's Building Services division is primarily responsible for reviewing and approving residential structural drawings. This department ensures that your building plans align with local codes and standards. Submitting plans that are stamped by a licensed structural engineer is typically required, and the city may also request additional documentation depending on the scope of the work.

Alberta Building Code Compliance

All submitted structural drawings must comply with the Alberta Building Code. The code governs construction standards and ensures the safety, health, and accessibility of new residential structures and renovations. Engineers preparing the drawings must be well-versed in these standards to ensure timely approval.

The Role of a Licensed Structural Engineer

Who Can Create and Stamp Structural Drawings?

Only a licensed professional engineer (P.Eng.) registered with APEGA (Association of Professional Engineers and Geoscientists of Alberta) can legally stamp and submit structural drawings for approval. At Calgary Structural Engineers, our licensed engineers specialize in designing safe, code-compliant residential structures across Calgary.

Why the Engineer’s Stamp Matters

A structural engineer’s stamp confirms that the design has been reviewed and meets the required codes and technical standards. Without this stamp, the city will not proceed with the permit review. This is a safeguard to ensure public safety and the integrity of the structure.

Submission Process for Structural Drawings

How to Submit Structural Drawings to the City

Drawings can be submitted online via the City of Calgary’s ePermit system or in person at the Planning Services Centre. When submitting, you’ll need the following:

• Stamped structural drawings
• Building permit application form
• Site plans
• Scope of work description
• Additional documentation depending on the project (e.g., energy code analysis)

Timeline for Approval

Approval times vary based on the complexity of the project. Simple residential projects like a single-family home addition might take a few weeks, while more complex builds can take longer. The City of Calgary provides estimated processing times on their website.

When Is Structural Approval Required?

Renovations vs. New Builds

Any structural modifications to a home — such as removing load-bearing walls, building additions, or creating secondary suites — require approval. New residential builds always require stamped structural drawings and a full permit review.

Common Projects That Need Approval

• Basement developments involving foundation changes
• Garage construction
• Decks and balconies
• Home additions
• Replacing or removing structural walls or beams

Common Questions About Residential Drawing Approvals in Calgary

What happens if I skip getting my structural drawings approved?

Skipping approval can result in fines, stop-work orders, or even having to tear down unapproved work. It's not worth the risk.

Do all home renovations need structural drawings?

Not necessarily. If your renovation affects load-bearing walls or structural systems, then yes. Cosmetic changes like flooring or paint don’t need structural drawings.

Can I draw my own plans and have an engineer stamp them?

In theory, yes. But most engineers won’t stamp drawings they didn’t prepare or closely review, since they’re taking legal responsibility for the work.

How much does it cost to get residential structural drawings approved in Calgary?

Costs vary, but plan for the engineer’s fees (typically $1,500-$3,000 for a residential project) plus city permit fees. Each project is different.

How long is a building permit valid in Calgary?

Building permits are generally valid for one year. You must start construction within this time, or you may need to reapply.

What if my permit gets denied?

If your permit is denied, you’ll receive feedback from the city. At Calgary Structural Engineers, we help you revise the drawings and address the issues to resubmit successfully.
