Intergenerational · Terrebonne · 2026
The exact category of the by-law in Terrebonne, its conditions, the permit fee, and the checklist before buying or converting.
Intergenerational home in Terrebonne in 2026: Terrebonne regulates three categories of accessory dwellings: the basement bachelor (prohibited in the former town of Lachenaie), the uniplex, which resembles an intergenerational home with no family link required and is allowed in a detached single-family home on a lot of at least 600 m², and the supplementary dwelling, allowed in homes across the Urbanova territory. The right applies to sectors that allow detached single-family homes, within the urban perimeter, outside public-safety constraints and outside heritage buildings; siting, construction, architecture and parking standards still apply. Permit required (form P-16, or P-05 if the dwelling needs an extension); fee per the fee by-law. 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.

From 21 August 2024 to 21 August 2029, the right-of-law lets an owner build an accessory dwelling even if zoning by-law 1001 or by-law 1009 does not allow it.

Permit required (form P-16, or P-05 if the dwelling needs an extension); fee per the fee by-law. If the dwelling houses a person with a family or marriage link to the owner-occupant, the City exempts the permit application fee (form P-16.1, declaration of family link) and refunded the applications paid in 2024. For a new build or an extension, the general fee is on our page building permit by city.
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 Terrebonne as elsewhere; our guide to the intergenerational home in Quebec compares the ten cities.

The family link, when required, is in the City's by-law; otherwise the category is an accessory or additional dwelling open to all.
Permit required (form P-16, or P-05 if the dwelling needs an extension); fee per the fee by-law.
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.
