Common Questions

Do you pull the building permit?
Yes — we pull the permit on your behalf for all basement finishing projects that require one. Legal rental suites always require a permit. We handle the application and inspections.
How long does a basement finishing take?
A typical basement finish takes 3–6 weeks. A full legal rental suite with bathroom, kitchen rough-in, and egress windows may take 6–10 weeks depending on permit timelines.
What makes a basement rental suite legal in Ontario?
A legal suite requires a separate entrance or shared entrance with proper separation, a bedroom with egress window, a bathroom, smoke and CO detectors, proper fire separation from the upper unit, and a building permit.
Do you do the electrical?
We coordinate all electrical work with our licensed electricians. Pot lights, panel upgrades, separate meter installation, and AFCI breakers are all handled in-house.
How much does basement finishing cost?
A basic open-concept basement finish starts around $25,000–$35,000. A full legal rental suite with bathroom and kitchen rough-in typically ranges from $45,000–$75,000 depending on size and finishes.
