I want to move a load-bearing wall in our kitchen. Does that require a structural engineer, or can the contractor handle it?

Moving a load-bearing wall absolutely requires a structural engineer in Alberta — no contractor can legally approve this without proper engineering calculations and stamped drawings.

When you remove or modify a load-bearing wall, you're changing how your home's structural loads are distributed. This affects the safety and integrity of the entire structure above that wall. In Alberta, any structural modifications must be designed by a Professional Engineer (P.Eng.) registered with APEGA (Association of Professional Engineers and Geoscientists of Alberta). The engineer will provide stamped drawings showing how to safely redistribute the loads, typically with a beam, posts, or other structural elements.

The process involves several steps: First, your structural engineer will assess the existing structure and calculate the loads that wall currently carries. They'll then design a solution — often a steel or engineered lumber beam supported by posts or columns. The engineer provides stamped drawings that show the beam specifications, connection details, and any temporary support requirements during construction. Your contractor uses these drawings to obtain building permits and complete the work safely.

Calgary's building department requires these engineered drawings before issuing permits for load-bearing wall modifications. The Safety Codes Officer will review the plans and inspect the work at key stages — temporary support installation, beam installation, and final completion. Skipping this process isn't just unsafe; it's illegal and will cause problems when you sell your home or file insurance claims.

Costs typically range from $1,500-$3,500 for engineering (depending on complexity), plus $8,000-$25,000 for construction depending on the beam size, access challenges, and finishes required. The engineering fee is a small price for ensuring your family's safety and your home's structural integrity.

Your contractor's role is crucial but different — they handle the actual construction, temporary support systems, beam installation, and finishing work. However, they cannot determine what size beam you need or whether the wall is load-bearing without an engineer's assessment. Even experienced contractors must follow the engineer's specifications exactly.

Next steps: Contact a local structural engineer first to assess your wall and provide stamped drawings. Once you have those drawings, find contractors experienced with structural modifications through our Calgary directory. The engineer and contractor should coordinate on the temporary support plan and construction sequence to ensure your home remains safe throughout the project.
