Mechanical permit drawings for commercial spaces, HVAC layouts, kitchen exhaust, ventilation calculations, and plumbing coordination. Serving Toronto and the entire GTA.
Mechanical review is where a large share of commercial permit applications stall. Ventilation rates that don't meet code for the occupancy, kitchen exhaust that ignores makeup air, rooftop units placed without structural thought, examiners catch all of it.
We produce coordinated mechanical permit drawings for commercial projects: HVAC layouts and distribution, ventilation calculations matched to your actual occupancy, kitchen exhaust and makeup air systems for food service, and plumbing drawings from grease interceptors to barrier-free washrooms.
Our mechanical packages are coordinated against the architectural and structural drawings from day one, no ducts through beams, no units the roof can't carry, no conflicts discovered during construction.
Every drawing we produce is backed by 20+ years of hands-on commercial construction across the GTA. Before you start, you can price your project with our cost calculator, check your timeline with the timeline estimator, or read the Ontario permit guide. We know what plan examiners look for because we've stood on both sides of the process, and we know what contractors need because we've been the contractor. That combination is why our clients' applications move.
