Brampton has one of the largest stocks of detached, semi-detached and townhouse homes with finished basements in the GTA, and many include a second unit. The city also has a large number of warehouse and manufacturing buildings near Highways 407, 410 and 401. Parts of Brampton lie under Toronto Pearson flight paths, and the Kitchener GO rail line passes through the city. The result is a mix of residential, workplace and aircraft noise problems.
Ceiling and wall assemblies between a second unit and the main house often also serve as fire separations, so changes to them should be planned alongside the building permit and registration requirements. Soundproofing is separate from that process and does not replace it; check requirements with the City of Brampton or your designer before starting.
