Can I legally rent my basement in Brampton? The 2026 rules, step by step

The rules in Brampton

• Registration is mandatory. The City says all additional residential units, including older "legal non-conforming" second units, must be registered. It is a one-time process that confirms the unit meets the Ontario Building Code and the Zoning By-law.
• Up to 3 units per lot, counting the main house: either the house plus a basement unit plus a garden suite, or the house plus two attached units.
• Parking: no extra space is needed for a single second unit. One extra space is needed when a lot has two additional units (tandem parking is allowed).
• Rental licence: owners of rental properties with 1 to 4 units must hold a City rental licence. Current holders had to renew by January 31, 2026, and applying is free.
• Units are not allowed in lodging houses, supportive housing, floodplain areas or open-space zones.

How to make a Brampton basement legal

1. Check zoning and whether your lot can have a second unit (floodplain and lodging-house restrictions apply).
2. Get drawings that meet the Ontario Building Code: exits, ceiling height, fire separation, smoke and carbon monoxide alarms, and electrical.
3. Apply through the City’s two-unit / ARU registration and building permit process, and pass the inspections.
4. Register the unit, then apply for your free rental licence before you rent it out.
5. Use the Ontario standard lease and price the rent from recent nearby leases.

Ask the City (or your designer) for the current fees and the exact permit checklist before you start; they change, and I only quote what the City publishes.

How to check whether an address is registered

The City publishes a map and an open dataset of registered additional residential units, plus an ARU search tool. Search the address before you sign a lease or make an offer. The City notes the search tool does not replace its approval process, so for a purchase, confirm in writing.

What happens if it is not registered

• Administrative penalties of $1,000 to $1,500 for failing to register an ARU, and the same range for converting a room into a bedroom without a permit.
• Court fines under the Planning Act, Building Code Act and Municipal Act can be far higher, with daily penalties for continuing offences.
• The City can order the unit closed, which can force a tenant out on short notice and void your rental income.

Is it worth it?

A legal, registered unit adds rental income and resale value, and many buyers will only pay for a basement suite that is registered. Brampton condo one-bedrooms leased for about $2,052 in Q2 2026 (TRREB); a basement usually rents for less, but it can still cover a large share of your mortgage. See the legal basement guide, Brampton legal basement guide and Peel rents by city.
