Maryland Contractor License

Maryland licenses contractors primarily through the Maryland Home Improvement Commission (MHIC), which governs residential remodeling and home improvement work and requires an exam to qualify. The MHIC license covers most residential construction and remodeling, and crucially, subcontractors performing home improvement work also need their own MHIC license — not just the prime. New home builders register separately with the Attorney General, and home improvement salespersons must be registered under a licensed contractor. For estimators, that structure means you must confirm the right credential for the work category before bidding: residential remodeling routes to MHIC, while new construction routes to the separate builder registration.

An exam is required and NASCLA is not accepted, so out-of-state firms cannot shortcut qualification with a NASCLA credential, and Maryland lists no GC reciprocity. Specialty trades such as electrical, plumbing, HVAC, and master gas fitting are licensed separately, so price licensed trade subcontractors into your bid and verify each holds the proper Maryland license. Because subcontractors doing home improvement work need their own MHIC license, build that verification into your subcontractor selection rather than assuming the prime's license covers the chain.

The penalties for unlicensed contracting in Maryland are among the most serious: a misdemeanor, fines up to $5,000, imprisonment up to two years, and loss of the right to file liens. Losing lien rights on a Maryland project can leave you unable to collect on work you performed, which is a direct hit to the margin you bid. The safeguard is to identify the correct license category early, confirm your MHIC qualification and any separate builder registration, and verify that every home improvement subcontractor is independently licensed before you submit and before work begins.
