Common Questions

Are secondary suites legal in Ontario?
Yes. Ontario's Planning Act requires municipalities to permit secondary suites in most residential zones. Your unit must meet Ontario Building Code requirements to be legally rented — Zaki Construction ensures full compliance.

How much does an ADU cost?
Basement conversions typically range from $80,000–$150,000. Laneway and garden suites range from $100,000–$300,000+. We provide detailed estimates after a site review.

How long does construction take?
A basement apartment conversion typically takes 3–5 months from permit approval to handover. We provide a clear schedule before construction begins.

Do I need a permit?
Yes. Zaki Construction handles the entire permit application process — drawings, submissions, and municipal follow-up.

Can I rent it out immediately?
Yes — once the final inspection is passed and the occupancy permit is issued, your suite is legally rentable from day one.
