Garden Suites in Brampton - Design, Permits, Construction

Brampton has more unregistered basement apartments than any other GTA municipality, and the city's registration program is the pathway to making them legal. Roughly half our Brampton work is not new construction at all - it is fire separation, egress windows and interconnected alarms brought up to Ontario Building Code so an existing suite can be registered. Brampton's Residential Second Unit registration program plus the provincial three-unit permission make legalising an existing basement apartment the most frequent first step here.

Deep newer-subdivision lots, many with an existing unregistered basement apartment that must be brought to Ontario Building Code fire-separation standard. Brampton sees 126 cm of snow and -4.1°C winter averages.

A garden suite is a free-standing building in the rear yard, so the governing numbers on a Brampton lot are rear and side setbacks, the soft-landscaping percentage that has to survive, and the separation distance to the main house required for fire spread. Because it is new construction on undisturbed ground, the footings go to 1.2 m and the roof is engineered for 126 cm of annual snow load - both poured and framed inside the April-November season. Rear-yard access for the excavator is the practical gate: where deep newer-subdivision lots, many with an existing unregistered basement apartment that must be brought to ontario building code fire-separation standard, we plan side-yard machine access or crane placement before pricing.
