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. 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.
