What it typically costs
Basement finishing typically ranges from $25,000 for a straightforward rec-room build-out to $60,000+ for a self-contained legal suite with a separate entrance, bathroom, and kitchenette.
Local note: the City of Vaughan requires permits for a separate entrance, proper egress windows, and fire-separation compliance if you're finishing it as a legal second suite — factor inspection timelines into your schedule.
