What Can a Handyman Do in Saint Mary's in Saint Mary's County, Maryland?

In Saint Mary’s County, Maryland, most “handyman” work is legal without a state contractor license only if it stays under Maryland’s Home Improvement contractor threshold (small, minor repairs) and does not include regulated trades (electrical, plumbing, HVAC/gas) that require separate licenses. For most residential repair/replace/alter/improve jobs above the small-job threshold, Maryland requires Home Improvement Contractor (HIC) registration through the Maryland Home Improvement Commission (MHIC) and a surety bond.

In MD, jobs under $500 typically don't require a contractor license. Always verify with your local licensing authority.

✅ What You Can Do Without a License

Small handyman jobs at $500 or less (labor + materials) that do not require a trade license (MHIC small-job exemption)
Interior/exterior painting (non-lead abatement; lead-safe rules may apply in older homes)
Minor drywall patching and painting touch-ups
Basic carpentry that is non-structural (trim/baseboard, shelving, replacing interior doors in-kind)
Cabinet hardware replacement (pulls/knobs/hinges) and minor cabinet adjustments
Fence/gate repairs that do not require a building permit (depends on height/location rules)
Replacing plumbing/electrical fixtures ONLY where allowed by local code and where it does not cross into regulated work (always verify—many jurisdictions require licensed trades)
Yard/outdoor maintenance tasks that are not construction (pressure washing, minor caulking/weatherstripping)

⚠️ What Requires a License

Home improvement contracting over $500 total contract price (labor + materials) typically requires MHIC registration
Advertising or offering to perform home improvement work in Maryland generally requires MHIC registration (even before you start work)
Electrical contracting (new circuits, panel work, wiring, service upgrades) requires a Maryland electrician license and permits
Plumbing work beyond very minor like-for-like fixture swaps (water heater replacement, moving lines, drain/vent work) requires a Maryland plumbing license and permits
HVACR system installation/service (furnaces, heat pumps, AC condensers/air handlers, refrigerant work) requires Maryland HVACR licensing (and EPA 608 for refrigerants)

State Licensing Rules (MD)

This exemption does NOT allow you to perform work that requires a separate trade license (e.g., electrical/plumbing/HVAC/gas). It also does not waive local building permits or inspections. Splitting a larger job into multiple invoices to stay under $500 can be treated as evasion and still require MHIC registration.

Permit vs. Contractor License — What's the Difference?

A license (MHIC or trade license) is your legal authorization to perform/offer certain types of work. A permit is project-specific approval from the local building authority to do work at a specific address. In Maryland, even if a job is under the MHIC $500 small-job exemption, the work may still require a county building permit and inspections (especially electrical, plumbing, mechanical, or structural work).
