Who Can Sign Off On Structural Work In Calgary?

In Calgary, only a licensed professional engineer (P.Eng.) registered with APEGA (Association of Professional Engineers and Geoscientists of Alberta) can legally sign off on structural work.

At Calgary Structural Engineers, we offer this professional oversight to help you meet all city requirements and ensure your project is safe and compliant.

The Role of a Structural Engineer in Calgary Construction

What Does “Signing Off” on Structural Work Mean?

When an engineer signs off on structural work, they’re certifying that the design meets all applicable safety standards and building codes. Their signature also indicates that they will conduct or have conducted reviews during construction to ensure the design is properly executed.

Why a P.Eng. Is Required

• Legally recognized authority to approve structural designs
• Ensures compliance with the Alberta Building Code
• Provides liability coverage and professional accountability
• Required by the City of Calgary for permit approval

What Projects Require Sign-Off From a Structural Engineer?

Common Scenarios in Calgary

You’ll need a professional sign-off if your project involves:

• Removing load-bearing walls
• Changing structural framing
• Foundation alterations
• Creating new openings in walls
• Adding additional floors or extensions
• Constructing retaining walls over a certain height

Residential and Commercial Projects

Whether you're working on a single-family home, duplex, or commercial building, structural changes typically require approval from a professional engineer.

Legal Requirements: Alberta Building Code & City of Calgary

What the Building Code Says

The Alberta Building Code mandates that structural systems be designed and reviewed by qualified professionals. In Calgary, the permit application process often requires the submission of:

• Structural drawings
• Schedule B (Design Letter)
• Schedule C (Construction Review Letter)

APEGA Licensing Requirement

Only engineers licensed through APEGA can legally take responsibility for structural design and inspection. This ensures they have the education, experience, and ethical obligation to uphold public safety.

What Does the Sign-Off Include?

Schedule B: Design Letter of Assurance

• Confirms the design complies with relevant codes
• Lists applicable standards
• Includes the engineer’s seal and signature

Schedule C: Construction Review Letter

• Verifies construction matches the approved plans
• Confirms site inspections were conducted
• Reinforces professional accountability

Why It Matters Who Signs Off on Structural Work

Legal Compliance

Improper sign-off or unlicensed approval can result in permit delays, stop-work orders, or legal liabilities.

Safety and Code Adherence

A P.Eng. ensures that all structural work is safe and aligned with current codes, which protects homeowners, tenants, and property investments.

Streamlined Permit Approvals

Projects with proper engineering oversight and documentation are more likely to move through the permitting process efficiently.

Risk Reduction

Having a licensed professional accountable for the design and inspection helps prevent construction errors, structural failures, and costly corrections.

6 Questions People Ask About Structural Sign-Off in Calgary

Can a contractor sign off on structural changes?
