Maryland Contractor Licensing — What Homeowners Must Know
Maryland requires home improvement contractors to hold a Home Improvement Contractor (HIC) license from the Maryland Home Improvement Commission (MHIC). HVAC contractors also need HVAC-specific licensing. Verify at dllr.state.md.us/license/mhic. Unlicensed home improvement contracting is a misdemeanor in Maryland.
Maryland follows the International Residential Code with state and local amendments, with permits issued at the county level. Montgomery County, Prince George's County, Anne Arundel County, and Baltimore City each have separate building departments. Most residential projects require permits. Maryland's energy code requirements affect HVAC and window specifications.
Maryland's Home Improvement Commission Guaranty Fund compensates consumers (up to $15,000) harmed by licensed contractors. All licensed Maryland HIC contractors must contribute to the fund. Maryland also has a strong Consumer Protection Act providing remedies for contractor fraud.
Most homeowner policies cover sudden storm damage to siding, windows, and exterior structures but not gradual wear. Document your home's current exterior condition with dated photos before beginning work. Permit records and licensed contractor documentation create a code-compliance record that protects your coverage if a future weather event affects the same areas.
Best Time to Schedule Deck & Patio Work in Baltimore, MD
Best window: February through April, or September through October. Avoid if possible: June through August.
Spring and fall offer the best combination of contractor availability and installation conditions for exterior work in Baltimore. Avoid peak summer heat when sealant cure and crew productivity suffer, and ensure no sustained rain is forecast in the 48 hours following installation.
Scheduling tip for Baltimore: March is typically the best single month for scheduling in standard-climate markets: mild weather, lowest contractor demand of the year, and enough lead time to start before spring busy season. Get bids in February for March or April work.
