Interior Renovation Permit Drawings
Interior renovation permits may be required when residential work affects structure, plumbing, mechanical systems, openings or major layouts. We prepare project-specific permit drawings and coordinate supporting information for renovations across Toronto and the GTA.
Permit Requirements Depend on the Proposed Work
Cosmetic updates may not require a building permit. Renovations involving structural changes, plumbing, mechanical systems, new openings or major layout changes often require coordinated drawings and municipal review before construction begins.
- Load-bearing wall removal
- Structural beam installation
- Kitchen relocation
- Bathroom relocation
- New stair openings
- Window and door openings
- Plumbing changes
- HVAC modifications
We review the proposed work and available information to help identify the likely drawing, engineering and permit requirements.
