That basement could be doing more than storing boxes!
A legal secondary dwelling unit can be a smart way to turn unused space into rental income and in Ottawa, there’s more opportunity than you might think.
A few things to know:
• Secondary dwelling units are permitted in many Ottawa homes, subject to zoning requirements.
• Basement apartments have no maximum size limit under Ottawa’s current rules.
• Legal suites need to meet Building Code and Fire Code requirements, including proper fire separation, exits and life-safety systems.
• You’ll also want to consider permits, insurance, property taxes and the tax implications of rental income.
Thinking about turning your basement into an income-producing space? Now is the time to start planning. The right design can make the most of the space you already have while creating a comfortable, functional home for someone else and another source of income for you.
