Second units and city registration
Brampton requires a second unit to be registered with the city. A basement apartment that has not been registered is a legal question on the file, not just a feature of the listing.
More details
Brampton has more second units than most Ontario municipalities, and the city requires each one to be registered. A listing that advertises a basement apartment or in-law suite does not tell you whether it is registered, whether it was built under a permit, or whether it meets fire and electrical requirements. Where the rental income is part of your financing, the difference matters to the lender as well as to you, and it is a question to settle before the agreement is firm.
