Adding a legal secondary suite is one of the smartest investments a Calgary homeowner can make — increasing property value and generating rental income. But converting a basement into a safe, legal living space means meeting strict Alberta Building Code requirements, and that starts with hiring the right structural engineer for your basement suite in Calgary.
At Tam-Crete Engineering, we provide stamped permit drawings, on-site inspections, and full structural engineering support to get your basement suite approved by the City of Calgary.
When Does a Basement Suite Require a Structural Engineer?
Most legal basement suite conversions in Calgary require a structural engineer — especially when structural modifications are involved. You’ll need our services when:
- Egress Window Installation: Cutting into foundation walls to meet minimum window size and safety exit requirements under Alberta Building Code.
- Basement Walkout Entrance: Creating a separate entry point requires a structural header design and proper soil retention to protect your foundation.
- Load-Bearing Wall Removal: Reconfiguring your basement layout safely while maintaining the structural integrity of the home above. Learn more about our Beam Design & Wall Removal services.
- Foundation Assessment: Evaluating whether existing footings can support the additional loads of a finished, occupied suite.

Basement Frequently Asked Questions
Why is a structural engineer required for a legal basement suite in Calgary?
The City of Calgary requires stamped engineering drawings whenever the structural integrity of a home is altered — such as cutting egress windows or adding a separate entrance — to ensure the safety of future occupants.
Does a basement walkout entrance require structural engineering?
Yes. Creating a walkout involves excavating near the foundation and cutting through the main wall. A structural engineer must design the necessary headers and any retaining walls to prevent foundation failure.
How long does it take to receive basement suite permit drawings?
At Tam-Crete Engineering, we typically deliver stamped structural drawings within 5 to 10 business days following the initial site inspection, depending on project complexity.
Can Tam-Crete help legalize an existing non-compliant basement suite?
Yes. We can conduct a structural inspection and provide the remediation drawings or documentation required to bring an existing suite into compliance with current Calgary building codes.
