Basement renovation permits
Painting and flooring are different from adding bedrooms, plumbing, walls or a second dwelling unit. The scope of the renovation matters.

The short answer
Cosmetic finishes can be treated differently from creating bedrooms, changing exits, adding plumbing, altering structure or creating a suite. Finishing a basement is not automatically “no permit.”
“Finishing a basement” is not one permit category. The answer changes when the work includes bedrooms, structure, plumbing or a suite.
What to check first
- New or moved walls
- Bedrooms and egress windows
- New or moved plumbing
- A separate dwelling unit

If a permit is required
