Frequently asked questions

Is constructing a basement apartment a good investment?

While the cost of converting a basement into housing can be considerable, with the tenant’s monthly payments the investment will pay off in the long run and generate supplemental income.

What steps are required for the conversion of a multiplex building?

You must first obtain the necessary agreements from your municipal planning department. Next, you need to find a professional (architect, technologists or engineer) to obtain the type of plans that the city and the future contractor will require if there is structural work to be done. Once you have the plans, you’ll need to get them approved by your municipality and obtain a building permit. Finally, you’ll need to find a contractor who can successfully carry out the conversion.

What is a conversion to divided co-ownership?

As the name suggests, a divided co-ownership is when the property is divided and each of the co-owners owns a portion of the building, i.e a private section for their exclusive use, as well as a “share” of the common areas belonging to all the co-owners of the building. In this case, people own their condo and have access to common areas such as a gym or swimming pool, which are everyone’s property.
