Development Permits for New Builds in Montréal

In Montréal, Quebec, development permits are required for most new builds, exterior alterations and changes of use that affect zoning, setbacks or land use. Early contact with the city’s planning office helps avoid delays: municipal zoning by-laws and permit rules govern approvals and conditions. This guide explains when to apply, what to include in an application, typical timelines and enforcement paths for developments within Montréal.

Overview

A development permit authorizes construction, major renovations or land-use changes under the City of Montréal’s planning rules. Applications must show plans, site information and supporting documents; requirements depend on zone and project size. For general permit categories and initial steps see the City of Montréal permits page Permits and certificates^[1] and the city planning overview Urban planning^[2].
