FAQ — Basement Finishing in Cambridge
Do basements need permits?
Yes. Any basement finishing project in Massachusetts requires a building permit, and bedrooms specifically require an egress window meeting state code (5.7 sq ft, 24" min height, 20" min width, sill height ≤ 44").
What if my basement gets water?
We address moisture before finishing — French drains, sump pumps, exterior waterproofing, or interior dimple membranes. We don't frame over a wet basement; we fix the source first, then deliver a 5-year warranty against water in the finished space.
Can I add a bathroom in my basement?
Almost always. We use up-flush toilets (Saniflo) or sewage ejector pumps when the basement is below the main sewer line. Adding a basement bath typically runs $12K–$25K and adds another 4–6 weeks to the project.
How low can my ceiling be?
Massachusetts code requires 6'8" minimum finished ceiling height in habitable space. We've made many "too low" basements work by removing low-hanging ductwork, re-routing pipes, and using slim LED downlights. We assess ceiling height during the first visit.
