Building Permit Packages

Truss and EWP Designs for Your Building Permit Package

Most permit applications for a new home, addition, or garage need stamped structural documentation for the roof and floor systems. That's the piece we handle.

Send us your plans and our design team returns truss layouts, EWP floor designs, specifications, and engineering that meet Ontario Building Code requirements — ready to go into your submission.

Send drawings to our Customer Service Team or talk to your local branch. We'll confirm scope and turnaround before we start.

What you get

Stamped structural design and layouts. Detailed drawings for roof trusses, floor trusses, and EWP floor systems — layout, spacing, member sizes, and configuration, with the engineering calculations behind them.

Code compliance you can submit. Designs demonstrate load-bearing capacity, safety factors, and the other structural requirements your building department will check. They go into your application as-is.

Documentation your crew can build from. The same drawings guide installation on site and coordinate truss and EWP placement with mechanical and electrical runs, so the inspector and the framer are working from one source of truth.

Building for the first time? Start here.

A permit package is the set of drawings and documents your municipality reviews before it lets you build. It proves your project meets the building code, zoning rules, and safety standards. Nothing gets built until it's approved.

A typical residential package includes:

• Site plan — where the structure sits on your property, setbacks, lot coverage. Usually from a surveyor or designer.
• Architectural drawings — floor plans, elevations, cross-sections. From an architect or a BCIN-qualified designer.
• Structural details — beams, headers, foundations. From your designer or engineer.
• Roof and floor system designs — stamped truss and EWP layouts. This is what we provide.
• Mechanical and other documents — HVAC, plumbing, energy efficiency, varying by municipality.

Where we fit

Once you have architectural drawings, they come to us — from your builder, your designer, or from you directly if you're acting as your own general contractor. We design the roof trusses, floor trusses, and engineered wood floor systems to suit those plans, and return sealed drawings and engineering for your application.

We don't produce the architectural drawings or submit the application on your behalf.

A realistic order of operations

1. Talk to your municipality about what your project requires — requirements vary, and it's a free conversation.
2. Hire a designer or architect for your drawings.
3. Send us your drawings for the roof and floor systems. You can do this yourself if you're managing the build. If you're not sure your drawings have what we need, send them anyway and we'll tell you what's missing.
4. Submit the package. Expect revision requests; they're normal.
5. Approval, then build.

Not sure where you are in this? Call your local branch. We've walked a lot of first-time builders through it, and we'll tell you straight if what you need is a designer rather than us.
