Today its planning sector has the highest share of owner-occupied homes among Laval's six sectors, 81.2% of households, and 66.1% of dwellings are single-detached houses.

Before an outdoor unit goes in
Rue Principale is a heritage territory under Laval's PIIA review (Code de l'urbanisme, section 12). One of its criteria asks that technical equipment be concealed from the street or public space. Ask the City if your project needs PIIA approval before installation; we place the unit out of street view where the lot allows and size it to meet the rules.
