Engineering & Municipal Approvals

- Committee of Adjustment & Minor Variance - zoning relief built to satisfy the four statutory tests
- MEP Drawings - HVAC, plumbing, and electrical layouts coordinated with your permit set
- Site Grading & Servicing Plans - lot grading, drainage, and stormwater management
Commercial Building Permit Services
We prepare permit drawings for retail stores, restaurants, offices, medical clinics, and mixed-use developments. Our commercial packages include full OBC life safety compliance, accessibility reviews under the Ontario Building Code Part 3 requirements, and coordination with mechanical and electrical consultants.
- Commercial Building Permit Drawings - tenant improvements, fit-outs, and change of use
- Restaurant & Commercial Kitchen Fit-Outs - grease exhaust, plumbing, and occupancy load
