Modular construction in Saint-Lazare
As elsewhere in the Vaudreuil-Soulanges MRC, residential projects in Saint-Lazare most often happen on private land — the context where the modular approach makes the most sense. The home is factory-built, sheltered from the weather, then transported and assembled on a permanent foundation, reducing time spent on site accordingly.
On top of the building price, a project in Saint-Lazare carries off-factory costs: the land, the foundation, the connections — water and sewer, or well and septic depending on the sector — and module transport. That total is what you should compare from one builder to the next. On a permanent foundation, the home then finances like any other property.

Permits and regulations in Saint-Lazare
Saint-Lazare's zoning dictates where and how the home can be sited (setbacks, height, placement), and a municipal permit is required before work begins. The Quebec Building Code (RBQ) applies to the whole project; the factory-built portion is governed by CSA A277 certification, while the foundation, connections and assembly are inspected by the municipality.
Check zoning rules and permit applications directly with the municipality: www.ville.saint-lazare.qc.ca.

Modular builders serving Saint-Lazare
