Intergenerational · Gatineau · 2026
The exact category of the by-law in Gatineau, its conditions, the permit fee, and the checklist before buying or converting.
Intergenerational home in Gatineau in 2026: Gatineau's zoning by-law 532-2020 does not define an intergenerational dwelling in residential neighbourhoods: the only mention is the “multigenerational dwelling” of a home attached to a farm, which is not counted in the dwelling-to-building ratio. The application is filed online with the form to increase or decrease the number of dwellings in an existing residential building, with the estimate of the total cost of work; an acknowledgment gives a file number. Permit fee (by-law 501-2005, section 104): $880 per dwelling added; alteration or extension of a main building $3. Everywhere in Quebec, zoning may allow a single supplementary dwelling per main dwelling, reserved for family or not depending on the city, and the 2024-2029 by-right rule allows an accessory dwelling in a detached single-family home within the urban perimeter. Caregiver tax credit of $1,494 for a parent aged 70 or over who lives with you. Sources read on 16 September 2026.
Gatineau's zoning by-law 532-2020 does not define an intergenerational dwelling in residential neighbourhoods: the only mention is the “multigenerational dwelling” of a home attached to a farm, which is not counted in the dwelling-to-building ratio. In town, adding a dwelling to a single-family home means changing the number of dwellings in the building, for example from single-family to duplex, if the zone's grid allows it.

Québec.ca (urban planning decision guide, “Logement intergénérationnel”, updated 31 August 2026): the zoning by-law may allow a single supplementary dwelling per main dwelling, intended for people in an established category who have, or have had, a family or marriage link with the main occupant, and the municipality sets the conditions of layout and occupancy, which may vary from one category of buildings to another. From 21 August 2024 to 21 August 2029, the Act to amend various legislative provisions respecting housing allows an accessory dwelling to be built by right in a detached single-family home located within the urban perimeter, outside places subject to public-safety constraints and outside heritage buildings, even if the zoning by-law does not allow it (summary published by the City of Terrebonne). The caregiver tax credit (caregiver tax credit of $1,494 for a person aged 70 or over who lives with you, and of $1,494 to $2,988 for an adult with an impairment living with you) and the GCR warranty on a new intergenerational build apply in Gatineau as elsewhere; our guide to the intergenerational home in Quebec compares the ten cities.

Yes, when the unit has its permit and respects the City's category: it appeals to families looking for exactly that and to buyers who see one more dwelling. Without a permit, it sells for less and more slowly.
