Handyman License Requirements in Rockville, MD

By Ray Duke, Founder of Bulletproof Handyman · Last reviewed July 2026

Maryland has NO dollar-based handyman exemption—any residential home improvement work requires an MHIC (Maryland Home Improvement Contractor) license, regardless of project size. Handymen in Rockville must obtain a state MHIC license ($281.25 application fee), a city business license from Rockville, and separate trade licenses for electrical, plumbing, or HVAC work. Even minor repairs like caulking or fixture changes legally require licensing in Maryland.

⚠️ What Requires a Contractor License

The following work requires a state-issued contractor license in MD. Performing this work without a license exposes you to fines, stop-work orders, and civil liability:

• ANY residential home improvement work on 1-3 unit buildings: repairs, alterations, remodeling, replacements, additions (requires MHIC license)

Special Jurisdictions & Zones

Permit vs. Contractor License — The Legal Difference

A LICENSE is a credential issued by the state or city that proves you are qualified to perform certain work. A PERMIT is a project-specific authorization issued by the city/county that allows you to perform work on a specific property. You need BOTH: a license to legally perform the work, AND a permit to legally perform that work on that specific property. Even if you hold an MHIC license, you still need building permits for most residential projects. Permits are issued by the City of Rockville (or Montgomery County for unincorporated areas) and must be obtained BEFORE work begins.

Business Entity Registration (MD)

To operate legally you must register your business. LLC filing fee in MD: $100 (one-time).

Compliance Notes for Rockville, Maryland (Montgomery County)

• Maryland has NO handyman exemption: Even a $50 job requires an MHIC license. This is one of the strictest states in the nation.
• Trade licenses are SEPARATE from MHIC: You cannot perform electrical, plumbing, or HVAC work with just an MHIC license. You need separate state licenses for each trade.
• Penalties are severe: Unlicensed contracting is a misdemeanor. First offense: up to $1,000 fine and 30 days jail. Subsequent offenses: up to $5,000 and 2 years jail. You also cannot sue for unpaid work if unlicensed.
• Subcontractors are exempt: If you work for an MHIC-licensed contractor, you do NOT need your own MHIC license. This is a common compliance strategy.
• Insurance is critical: General liability insurance ($300,000 minimum) is required for plumbing work and strongly recommended for all contracting. Maryland State Board of Plumbing must be named as certificate holder.
• Permits are separate from licenses: Even with an MHIC license, you must obtain building permits from Rockville for most residential projects. Permits must be obtained BEFORE work begins.
• Rockville has strict requirements: The City of Rockville operates independent permitting and has a historic district with additional requirements. Always verify with the city before starting work.
• WSSC jurisdiction: Rockville is within the Washington Suburban Sanitary Commission (WSSC) service area. Confirm whether separate plumbing registration is required with WSSC.
• Federal property nearby: The NIH campus is 5-10 miles away. Federal work requires SAM.gov registration and federal contractor compliance.
