The short answerPermit likely required

Yes. Toronto has a dedicated building-permit route for constructing a new residential basement entrance.

A basement entrance can affect the foundation, grading, stairs, exits, trees and zoning. The permit package must show the proposed work clearly, and professional design documentation may apply when engineering content is involved.

A few questions you might have.

Is a basement entrance permit the same as an underpinning permit?

No. Toronto groups related residential guidance, but the scope can be a new basement entrance without underpinning. Describe the actual work in the application.

Can a basement entrance affect more than the building permit?

Yes. The design can raise zoning, drainage, tree and structural questions, so the property and proposed work still need to be checked.
