Does converting a garage reduce property value in New Brunswick real estate?

Converting a garage can either increase or decrease your property value in New Brunswick, depending on how well the conversion is executed, whether the work is permitted, and how much demand exists for garage parking in your neighbourhood. In many NB communities — particularly suburban areas of Moncton, Fredericton, and Saint John where two-car garages are the norm — removing a functional garage to create living space can reduce your home's appeal to buyers who prioritize vehicle storage and winter protection.

The key factor is whether the conversion adds genuinely usable, code-compliant living space while the property retains adequate vehicle storage. A well-executed conversion of a two-car attached garage into a legal accessory dwelling unit (ADU) or in-law suite can add $30,000 to $60,000 in assessed value if the work is permitted, inspected, and meets NB Building Code standards for habitable space — including proper insulation, egress windows, fire separation, electrical, and HVAC. However, if the same conversion is done without permits, with substandard finishing, or in a neighbourhood where every comparable home has a two-car garage and yours now has none, the net effect on resale value can be neutral or even negative.

NB Market Considerations

New Brunswick's real estate market places significant practical value on garage space because of the province's long, harsh winters. Homeowners in NB use garages not just for parking but for protecting vehicles from -20 to -30 degree Celsius temperatures, storing snow blowers and winter equipment, and keeping road salt and ice off their vehicles. A home without a garage in a neighbourhood where every other home has one is a harder sell, especially in northern NB communities like Bathurst, Edmundston, and Campbellton where winters are particularly severe. Real estate agents in NB consistently report that a missing garage is one of the top objections buyers raise during showings.

That said, the NB housing market is evolving. With increasing demand for rental income and multi-generational housing, a properly converted garage suite with its own entrance, bathroom, and kitchenette can generate $800 to $1,200 per month in rental income in cities like Moncton and Fredericton. For homeowners planning to stay long-term, this rental income may matter more than the theoretical impact on resale value. The conversion cost of $25,000 to $50,000 can pay for itself within a few years through rental revenue.

Practical tips to protect your property value during a conversion: First, always obtain building permits — unpermitted conversions must be disclosed during a sale and can derail financing and insurance. Second, consider converting only part of a two-car garage if possible, retaining one bay for vehicle storage while converting the other into a workshop, studio, or living space. Third, maintain the exterior appearance of the garage — replacing the overhead door with a wall and window rather than simply drywalling behind the existing door preserves curb appeal. Fourth, ensure the conversion meets all NB Building Code requirements for the intended use, including R-20 minimum wall insulation, proper vapour barriers for NB's Maritime climate, egress windows in any sleeping area, and fire separation if the space shares a wall with the main dwelling.

Before committing to a garage conversion, consult a local real estate agent familiar with your specific neighbourhood and a professional contractor experienced with NB conversions. They can help you assess whether the conversion will add value in your market and ensure the work is done to code.
