Vieux-Rosemont grew up beside the Angus railway shops, which built locomotives from the early 1900s, while the Petite-Patrie was mostly farmland until the late 1800s.

Before an outdoor unit goes in
Rosemont–La Petite-Patrie requires a permit for a permanent heat pump or air conditioner. Front yards are off limits, balconies facing the front yard included, and the unit must stand at least 1.5 m from lot lines. Condo work needs a letter from each co-owner or a syndicate resolution. Check the permit with the borough before installation; we size and place the unit to meet it.
