Frequently Asked Questions
Is a separate entrance required for a legal basement apartment in Ontario?
A separate means of access is required, but it doesn't have to be an exterior entrance. Ontario Building Code allows either an interior shared hallway or an exterior separate entrance. However, many homeowners prefer an exterior separate entrance for tenant privacy and convenience.
