Stairs & Railings Engineering in Kelowna & Western Canada
Precision-Built Custom Stairs & Railings for Homes & Commercial Projects
Stairs serve a purpose, but they also make a statement. At Trueline, we engineer stair systems that are both structurally sound and visually striking. Our stairs engineering services combine expert craftsmanship, architectural design, and structural know-how to bring your stair vision to life safely and beautifully.
Whether you’re planning a luxury home, a renovation, or a commercial development, we work with home builders, homeowners, contractors, and designers to deliver fully engineered stair systems across Kelowna and the Okanagan.



Trueline’s Engineering Process for Stairs & Railings
When engineering is required by your municipality, Trueline manages the entire process for you: we create detailed shop drawings, have them reviewed and sealed by our engineer, manufacture and install to exact specifications, and coordinate a final engineer site inspection. Once approved, the engineer will issue the required documentation to meet municipal building permit requirements.
The Technical Side of Stair Design
Stair engineering is the behind-the-scenes work that makes stunning staircases possible. It’s the process of translating your design into a fully functional, structurally sound, code-compliant stair system that fits your space with exacting precision. At Trueline, we handle every stage in-house, from concept and CAD drawings to fabrication and installation.

When Is Engineering Required
Engineering for stairs and/or railings is not always mandatory; however, it is essential to verify the specific requirements with your municipality’s Building and Permitting Department. Should engineering be required, it is imperative to consult with a Trueline Moulding representative early in the process to ensure that the appropriate structural framing is incorporated during the framing stage.
Given the ongoing changes within the industry, it is always advisable to confirm current requirements before proceeding with any stair or railing project. Engineering documentation is most commonly required for mono (single) stringer stair designs and glass railing systems.
Our Stair Engineering Process
We start by understanding your layout, design goals, materials, and timeline.
Our team conducts on-site measurements to ensure perfect fit and alignment with your framing and floor plan.
We produce detailed CAD drawings that outline rise, run, headroom, load-bearing elements, and local building code compliance.
