Price drivers
What makes a basement cost more
- Size. More square footage means more framing, drywall and flooring.
- Bathroom. Cheaper if your home already has a plumbing rough-in.
- Bedrooms. Each one needs an egress window, and small basement windows must be enlarged.
- A legal suite. Adds a kitchen, fire separation, alarms and often a separate entrance.
- Heating changes. Moving ducts or adding a second furnace for a suite.
- Finishes. Flooring, cabinets and fixtures can swing the total by tens of thousands.
