Mississauga Basement Renovation FAQ

Can you build a legal basement apartment in Mississauga?

Yes, where the basement meets ceiling-height, egress and fire-separation requirements. A legal secondary suite needs permits, which we help review before construction.

Can you add a bathroom to my basement?

Yes. A basement bathroom is one of the most common additions; we coordinate the plumbing, waterproofing and finishing.

How long does a basement renovation take?

Most basement finishes take about four to eight weeks depending on size, whether a bathroom or kitchen is added, and permit timelines.
