Home / Permits / Basement finishing

Do you need a permit for a basement finishing?

Yes. Framing, electrical and any plumbing all need permits in every north-suburb village, and a legal basement bedroom needs an egress window sized to code. Fees typically run $200 to $900 or more, with framing, rough trade, insulation and final inspections. An unpermitted basement is the first thing that surfaces when the house is sold.

Typical fee: $200-$900+, scaled to project value in most villages.
