Frequently Asked Questions

Common questions about legal basement apartments in Brampton.
How much does a legal basement apartment cost in Brampton?+

Most legal basement apartments range from $35,000–$85,000 depending on size, existing conditions, and finish level. A typical 600–800 sq ft unit with basic finishes costs $45,000–$60,000. High-end finishes, structural repairs, or adding a side entrance from scratch can push costs higher.

Do I need a permit for a basement apartment in Brampton?+

Yes, absolutely. Any basement apartment used as a rental or separate living unit requires a building permit from the City of Brampton. Unpermitted apartments risk fines ($50,000+), insurance denial, and forced removal. We handle all permit applications and inspections for you.

How long does it take to build a legal basement apartment?+

Typical timeline is 6–10 weeks from permit approval to final occupancy. This includes 2–3 weeks for permits, 4–6 weeks for construction, and 1 week for final inspection and approval. Complex projects (adding egress windows, side entrances, or major structural work) may take 10–14 weeks.

What are the requirements for an egress window?+

Brampton requires a minimum 3.8 sq ft opening (not including frame), with the bottom no higher than 5' from the floor.

Do I need a separate entrance for a legal basement apartment?+

Yes, but it doesn't have to be completely separate. You can share a foyer as long as there's a locked door separating your main residence from the rental unit. Many homeowners add a side entrance for complete privacy, we can design either option based on your property layout and budget.
