What Building Permits Are Required For Structural Work In Calgary?

In Calgary, structural work such as altering load-bearing walls, modifying foundations, or constructing additions requires specific building permits from the City of Calgary. These permits ensure your renovation meets Alberta Building Code standards and is safely executed. Understanding what’s needed—and when to involve a structural engineer—can save time, money, and complications.

Understanding Calgary’s Permit System for Structural Work

Why Permits Are Necessary

Building permits exist to ensure renovations meet safety codes and structural standards. When your renovation involves structural changes, the City of Calgary must review and approve your plans to verify they are compliant with the Alberta Building Code.

When Structural Work Triggers Permit Requirements

Any renovation that impacts the stability or load-bearing capacity of your home requires permits. This includes:

• Removing or altering load-bearing walls
• Excavating or modifying basements
• Constructing additions or new stories
• Changing roof structures
• Replacing or enlarging structural windows or doors

What Types of Permits Are Required for Structural Work?

Building Permit

This is the primary permit for structural renovations. It confirms that the work complies with building codes. A structural engineer’s stamped drawings are typically required to obtain this permit.

Development Permit

In some cases, especially for additions, a development permit may be needed. This ensures the project meets zoning regulations, land use bylaws, and neighborhood design requirements.

Electrical, Plumbing, and HVAC Permits

If your structural work involves moving or installing new utilities, additional permits may be needed alongside the building permit.

When You Need Engineered Drawings

Structural Alterations

If you’re modifying beams, supports, or foundations, you will need engineered drawings from a licensed structural engineer. The City of Calgary requires these stamped plans for approval.

New Construction or Additions

New garages, sunrooms, or additional floors require structural analysis. Permits won’t be approved without engineered designs that prove the project’s safety and compliance.

Foundation Work

Permits for underpinning, retaining walls, or new foundations must be accompanied by professional engineering documentation.

Who Issues and Reviews Structural Work Permits?

City of Calgary Planning & Development Services

The Planning & Development department reviews building permit applications, ensuring structural components meet code. They will not issue a permit for structural work unless all required documentation—including engineered drawings—is included.

Role of the Structural Engineer

Your structural engineer provides the technical drawings and calculations needed for permit approval. At Calgary Structural Engineers, we help prepare permit-ready packages that minimize delays.

Benefits of Obtaining Proper Permits

Safety and Structural Integrity

Permits ensure that work is reviewed and inspected for code compliance, reducing the risk of future problems.

Legal Protection

Unpermitted structural work can lead to fines, denied insurance claims, and even forced demolition.

Smooth Resale

Homebuyers and real estate agents want documentation. Having proper permits and engineering drawings makes your property easier to sell.

The Structural Permit Process in Calgary

1. Hire a Licensed Structural Engineer

Your engineer conducts a site assessment and prepares drawings based on the proposed changes.

2. Prepare and Submit Permit Application

Your application includes forms, engineered drawings, and applicable fees. Calgary Structural Engineers can guide you through this step.

3. City Review and Approval

The City of Calgary reviews all documents. If approved, permits are issued. If not, they may request revisions.

Inspections are conducted throughout the build to ensure compliance. The final inspection confirms the project was built according to code.
