Modular construction in Carleton-sur-Mer

Carleton-sur-Mer at a glance

Affordable prefab housing is coming to Carleton-sur-Mer

Carleton-sur-Meris one of the 17 municipalities in the 478-unit affordable prefab housing contract carried by the Société de développement de l’Est, reported by La Presse in August 2026 — one of the largest contracts of its kind in Quebec history, according to the people behind it. On average, each participating municipality will receive 24 of these units. The municipalities provide the land, Quebec and Ottawa provide financing, and the six-unit buildings are assembled from modules built in Quebec factories. First deliveries are expected from spring 2027. Our article breaks down the structure, per-door costs and selected manufacturers.

Modular construction in Carleton-sur-Mer

In Carleton-sur-Mer and the Gaspésie--Îles-de-la-Madeleine region, modular construction is especially suited to residential projects on private land. Modules are built in a factory, sheltered from the weather, then delivered and assembled on a permanent foundation — cutting on-site timelines and weather dependence, two very real constraints outside the major centres.

The real budget for a project in Carleton-sur-Mer is made up of the building, the land, the foundation, the connections and transport. Each item varies with the lot you choose: a lot served by municipal water is not the same job as one needing a well and septic system. Financing, for its part, works like any other property once the home sits on its foundation.

Permits and regulations in Carleton-sur-Mer

First things first, the permit: the municipality of Carleton-sur-Mer must authorize the project, which remains subject to the Quebec Building Code (RBQ). Zoning sets the permitted setbacks, siting and height. In the factory, fabrication falls under CSA A277 certification; on the lot, the foundation, connections and assembly go through municipal inspection.
