A code-compliant secondary suite — separate entrance, kitchen, bathroom, and proper egress.
Book a Free ConsultationA legal secondary suite goes beyond a standard finish: it needs its own entrance (often a new basement walk-up or side door), a full kitchen, a bathroom, proper egress windows sized for a bedroom, fire separation between the suite and the rest of the house, and — depending on the home's age — sometimes a separate electrical panel or meter.
Ontario's province-wide Additional Residential Unit rules generally allow up to two secondary suites on an existing house lot as-of-right, subject to servicing and Ontario Building Code requirements, but every property is different — lot size, existing plumbing stacks, ceiling height and parking all affect what's actually feasible.
Given the University of Guelph rental market, this is one of the most financially motivated renovations a Guelph homeowner can do — but it's also the project most worth getting a straight feasibility answer on before committing budget.
Depends on ceiling height, lot servicing, and whether a separate entrance and egress windows are feasible — this is the first thing the consultation checks before any design work.
