Interior Alteration & Renovation Permit Drawings

It depends on the scope of the renovation. A building permit is generally required when the work affects building structure, exits, fire separations, plumbing, heating or ventilation systems, or other regulated building components. Cosmetic work such as painting, flooring, or replacing finishes typically does not require a building permit. The specific requirements should be confirmed based on the proposed work and municipality.

Not necessarily. Removing or altering a wall can require a building permit, particularly if the wall is load-bearing or forms part of a required fire separation. Even a non-load-bearing wall may contain plumbing, electrical, mechanical services, or other building components that need to be addressed. Permit drawings should identify the existing and proposed wall conditions and any required structural or code-related changes.

The drawing package depends on the project scope, but may include existing and proposed floor plans, demolition plans, reflected ceiling plans, elevations, building sections, construction details, door and finish information, fire-separation details, and relevant building-code information. Structural, mechanical, plumbing, electrical, or other professional drawings may also be required depending on the proposed alterations.

Yes. The existing conditions are reviewed first to establish an accurate starting point for the proposed renovation. The design can then document the demolition and proposed alterations and address the applicable zoning and Ontario Building Code requirements. For commercial projects, additional requirements may apply depending on the building use, occupancy, fire protection, accessibility, and extent of the alterations.
