Utilities and Infrastructure Quebec 3 Minutes Read · published May 26, 2026 Flag of Quebec

Introduction

Developers planning new construction or major redevelopment in Ahuntsic-Cartierville, Quebec must follow borough and city rules for water and sewer connections. This guide summarizes the typical municipal steps, permitting interfaces with provincial plumbing and building rules, enforcement pathways, and practical actions to get a lawful connection installed and inspected.

Start permit planning early to avoid construction delays.

Process overview

Most projects require coordination between the developer, the borough's urban planning and public works teams, licensed plumbers, and bâtisseurs registered with provincial authorities. Typical steps include pre-application meetings, submission of plans, securing building and plumbing permits, scheduling municipal inspection for the public network tie-in, and final acceptance.

A pre-application meeting clarifies responsibilities and fees.

Requirements & permits

Requirements commonly include engineering plans for service lateral locations, confirmation of capacity and grades, licensed plumber certificates, and a permit for any work in the municipal right-of-way. Developers must also respect the provincial plumbing and construction codes enforced by the Régie du bâtiment du Québec.

  • Permit: building and plumbing permits as required by municipal and provincial rules.
  • Licensed contractor: licensed plumber or contractor for lateral works.
  • Scheduling: municipal inspection appointments for tie-in to main lines.

FAQ

Who issues the permit for a new lateral connection?

Report to the borough by-law enforcement or public works via the borough service portal listed in Resources.[1]
