Commercial Permit Drawings & Management — Toronto & GTA

🌡️ Mechanical & HVAC Drawings

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.

Why Permit By Design

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.

Frequently Asked Questions

Do I need mechanical drawings for a small fit-up?

If you're adding or moving diffusers, changing ventilation zones, adding washrooms, or installing any exhaust system — yes. Simple cosmetic work usually doesn't trigger mechanical review.

My contractor says his HVAC sub can 'design-build' it — why drawings?

Design-build works for simple scopes, but most GTA municipalities require mechanical drawings with the permit for commercial work. Proper drawings also protect you — you know what you're getting before it's installed.

Do you size kitchen exhaust systems?

Yes — hood sizing, duct routing, fire-wrapped shaft coordination, and makeup air are core to our restaurant work.
