Maryland Contractor License Exam Guide (2026)

How Maryland licenses contractors

The Maryland Home Improvement Commission (within DLLR) licenses contractors performing $5,000+ in home improvement work. PSI (test-takers.psiexams.com/mdhic) delivers the MHIC exam. Commercial GC licenses remain local (Baltimore City, Montgomery County, etc.).

Maryland contractors battle tidal surge, freeze–thaw along I-70, and 110°F humidity in Prince George’s County. Expect exam questions about flood vents, basement waterproofing, termite treatment, and energy code compliance for mixed-humid climates.

• Understand licensing/background check steps and disciplinary actions
• Know when deposits are capped at 1/3 of contract price
• Review OSHA, EPA lead rules, and energy code basics to cover the technical portion
