Can I build a legal second unit in my Vaughan basement?

Yes. The City of Vaughan permits additional residential units in most low-rise zones, subject to ceiling height, egress windows, fire separation, and parking requirements. We assess feasibility during the consultation and handle the permit application.

What ceiling height do I need?

You generally need 1.95 m of clear height in finished areas. Newer Vaughan builds usually exceed this. Older Thornhill and Woodbridge homes may need bench footing or underpinning, which we can quote separately.

How do you keep a finished basement warm and dry?

Rigid or spray foam against the foundation wall, continuous vapour control, insulated sub-floor systems, and a dedicated HVAC supply and return. We also review your sump pump, weeping tile and backwater valve before framing starts.

How much does a finished basement cost in Vaughan?

Most complete basements land between $60,000 and $130,000 depending on bathrooms, kitchens, and whether structural work or egress windows are required.
