How Much Does a Basement Renovation Cost in Cambridge? (2026 Guide)
Finishing a basement is priced by square footage and how much you add — a bathroom, egress windows, and waterproofing all move the number. Here's the breakdown.
What affects the cost
- Square footage being finished
- Whether a bathroom or wet bar is added (plumbing runs)
- Egress windows for legal bedrooms
- Any waterproofing or moisture control needed first
- Finishes — flooring, trim, lighting, and built-ins
Typical price range in Cambridge
A finished basement in Cambridge generally runs $35,000–$75,000, depending on size, a bathroom addition, and finish level.
Address any water or moisture issues before framing — it's far cheaper to solve now than to tear out finished walls later.
