A new semi-detached home near Rosemère can also serve a family plan: settling two generations a few steps apart, without housing them under the same roof.

That is the idea this article explores for anyone looking at a multigenerational home near Rosemère. Rather than one large house split into two units, BÉAcité, in Sainte-Julie, presents itself as an appealing alternative to the two-generation house: two separate semi-detached homes, one for the parents, the other for their grown children, each with its own door, kitchen, garage and garden.

Before going further, one clarification: no one can promise you two neighbouring homes today. The sales director is the one who knows which lots are available.

Rosemère has twice as many multigenerational households

According to the 2021 Census, 140 Rosemère households, or 2.7%, were multigenerational: three or more generations under one roof. That is almost double the Quebec share (1.4%) and Sainte-Julie's (1.3%). Large households are more common too: 10.1% have five or more people, compared with 6.1% in Quebec, and the average household size reaches 2.7 people.

In other words, living across several generations is nothing abstract in Rosemère. It is part of the landscape, and it raises practical questions when each person's needs change.

When grown children want to settle near their parents

The consultation the town held in spring 2026, in preparation for its 2026-2046 housing policy, brought those questions to the surface. Among the ideas noted in the consultation report: multigenerational housing that keeps family ties intact while encouraging mutual support. The policy itself lists models that foster mutual help and a mix of generations among its priorities.

It also quotes one remark heard along the way, roughly: my children would like to settle in Rosemère, but houses have become unaffordable. In the questionnaire, 82% of 25-to-34-year-olds said they were worried about rising property costs. According to the town, which relies on JLR data, the median sale price of single-family houses there was $785,000 in 2025, up 76% since 2019.

Multigenerational home near Rosemère: one roof or two?

The classic two-generation house puts two units in one building. It brings people together, but it also blends a lot: the entrance, sometimes the yard, the repairs, the decisions. BÉAcité works differently. Each of the project's 50 homes sits on its own lot, on Geoffrion and Bissonnette streets, so two households who choose BÉAcité each have a house of their own.

Your own front door: you visit each other, you don't bump into each other by necessity.
Your own garage and yard: each home has its garage, its garden-level backyard and its private garden.
Your own upkeep… handled: each house has its all-inclusive maintenance program, with no chores shared between the two households.
Your own home, if life changes: a move, a birth or a retirement doesn't turn the other household's life upside down.

A bungalow for some, a cottage for others

BÉAcité's three models let each household choose a house that fits its stage of life. Their floor areas, read from the plans:

semi-detached bungalow: 1,006 sq ft on the ground floor, all on one level, with a basement of the same size and a 294 sq ft garage;
Duo cottage: 2,018 sq ft of living space on two floors (858 sq ft downstairs, 1,160 sq ft upstairs), plus a basement and a garage; 2,356 sq ft with the optional mezzanine;
Urbain model: 1,622 sq ft of living space, on a 652 sq ft ground floor and a 970 sq ft upper floor.

One possible scenario: the bungalow for parents who want everything on one floor, the Duo cottage for the family with children. The homes already built show what that can look like: 405 Geoffrion Street has three bedrooms, a mezzanine and a rooftop terrace, while 423 is a three-bedroom Duo home with a finished basement and an open office. Every home has 9-foot ceilings on the ground floor, large windows, a quartz countertop, central air conditioning and central gas heating.

Questions to ask the representative

A two-household plan comes together by asking the right questions at the very first meeting:

which lots are still free, and can you reserve two close to each other, or even both halves of the same semi-detached pair? That needs checking; nothing is a given;
what timeline suits each household: the four turnkey homes available for immediate sale, the customizable homes ready in about four months, or one of the 20 homes still to be customized;
what the maintenance program covers, house by house;
the coverage of Quebec's mandatory guarantee plan for new residential buildings, which the representative will explain.

Daily life in Vilamo, from one house to the other

BÉAcité's site plan includes two parks and a retention pond between its two streets. In the Vilamo neighbourhood, a promenade is set aside for pedestrians, bikes and electrified transportation, every home is less than 300 m from a bus stop, and the commercial strip is within walking distance: medical services, a public market, restaurants, a Caisse Desjardins, a pharmacy. In Sainte-Julie, local public transit is free, which makes it easier for those who don't drive to get around.

The sales office at 435 Geoffrion Street receives visitors Monday to Friday, from 9 a.m. to 4 p.m.; in the evening and on Saturday and Sunday, visits are by appointment. Bring both generations: each will see the house with their own needs in mind. Eddy Guessous, sales director, answers at 514-812-9633 (call or text) and at ventes@beacite.com.

Conclusion

A multigenerational home near Rosemère doesn't have to be one big house. In Sainte-Julie, about 52 minutes away without traffic, BÉAcité offers two separate homes instead, each on its own lot, each with its upkeep taken care of. The share of multigenerational households in Rosemère shows the question is a real one; what remains is to check with the representative which lots can make your plan work.
