Licenses and certifications explained
The licenses and certifications that matter for basement finishing contractors, in plain English.
State or city contractor license
Legally requiredMost states license or register remodelers, and some leave it to cities. Where a license is required, working without one is illegal and usually voids your recourse. Check the number on the licensing board's own lookup.
National Association of the Remodeling Industry
The main remodeling trade body. Members agree to a code of ethics, and its Certified Remodeler (CR) designation requires experience plus an exam.
BBB Accredited Business
Accreditation means the firm agreed to BBB standards and pays a fee. The useful part is the complaint history, which you can read whether or not a firm is accredited.
Basement finishing contractors: common questions
Can I put a bedroom in my basement?
Only with an emergency escape opening, usually an egress window of a minimum size with a window well, plus the ceiling height your local code requires. Without them it cannot legally be sold as a bedroom.
