Legal Remedies Against Unlicensed Plumbers, Roofers, and HVAC Technicians in Maryland

Current as of: October 1, 2026 Consumer Protection Law Maryland
Maryland law fiercely protects homeowners from unlicensed contractors. While unenforceable contracts allow you to refuse payment for unpaid work, under CitaraManis v. Hallowell, 328 Md. 142 (MD Supreme Court 1992), you cannot automatically demand a full refund for completed services without proving actual injury or defective work.

Hiring a contractor without realizing they lack a valid state license can lead to disastrous consequences, from flooded basements to massive fire hazards. In Maryland, performing regulated home improvement work without a license is not just bad business; it is a crime. If you have been scammed by an unlicensed roofer, plumber, or HVAC technician, you have powerful legal tools at your disposal. Finding a qualified attorney through our US Lawyer Directory can help you invalidate the fraudulent contract and recover your money.

Step-by-Step Guide to Handling Unlicensed Contractors

Whether you reside in Hagerstown, Gaithersburg, or Bowie, the steps to protect yourself from an unlicensed scammer remain the same. The law heavily favors the homeowner in these disputes.

Step 1: Stop All Payments

If you discover the worker is unlicensed, do not give them another dime. In Maryland, contracts made by unlicensed contractors are generally considered void and unenforceable against the homeowner. The landmark legal precedent for this is Harry Berenter, Inc. v. Berman, 258 Md. 290 (MD Supreme Court 1970), which firmly established that an unlicensed contractor cannot use the courts to sue a homeowner for unpaid work because the underlying contract is illegal.

Step 2: File a State Regulatory Complaint

You must report the illegal activity to protect yourself and others. You can file complaints against specific trades with the Department of Labor. For example, use Form Complaint, Maryland, Department of Labor, Division of Occupational and Professional Licensing Complaint Form. This alerts the state agencies, which can levy massive fines against the fraudster.

Step 3: File a Civil Lawsuit for Restitution

Because you cannot use the MHIC Guaranty Fund for unlicensed workers, you will need to file a civil lawsuit to get your deposit back. Your attorney can file an action in a court like the Circuit Court for Anne Arundel County, Annapolis or the local District Court, demanding the return of unearned money and damages for any property destruction caused by their incompetence.

Scenarios of Unlicensed Contractor Fraud

Different trades present unique dangers when performed by individuals lacking the proper training, bonding, and state oversight.

Emergency Plumbing Scams

When a pipe bursts at 2:00 AM, homeowners often panic and hire the first person they find online. Unlicensed plumbers may arrive, perform a sloppy temporary fix, and demand thousands in cash. Plumbing in Maryland requires strict adherence to safety codes. You should report these individuals to the Maryland Board of Plumbing, Baltimore, as improper plumbing can lead to raw sewage backups and catastrophic water damage.

Unlicensed Electrical Work Hazards

Electrical work is arguably the most dangerous trade. Unlicensed 'handymen' often wire panels incorrectly, bypassing necessary breakers and creating hidden fire hazards inside your walls. Because they cannot legally pull a county permit, their work is entirely uninspected. If an unlicensed electrician damages your home, you must hire a licensed professional immediately to make the house safe.

Botched HVAC Installations

Heating and cooling systems involve high-voltage electricity, combustible natural gas, and pressurized refrigerants. Unlicensed HVAC techs might install a furnace that leaks carbon monoxide into your living room. Such actions should be reported immediately to the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors, Baltimore. Replacing a ruined HVAC unit often costs upwards of $10,000, which you can seek in a civil lawsuit.

Unregistered Tree Removal Services

Tree removal is highly hazardous. Unlicensed 'tree guys' often operate without liability insurance or workers' compensation. If they drop a massive oak branch onto your neighbor's roof, or if one of their workers falls out of a tree on your property, the lack of insurance creates a massive legal nightmare. Always verify their standing before allowing chainsaws on your property.

Criminal Penalties and Financial Costs

Maryland takes unlicensed contracting very seriously.

  • Criminal Charges: Operating without a license carries criminal misdemeanor penalties across specific trades. For home improvement contractors and roofers, Md. Code Ann., Bus. Reg. § 8-601 imposes up to 6 months in jail and a $1,000 fine for a first offense. Performing unlicensed plumbing services is prohibited under Md. Code Ann., Bus. Occ. & Prof. § 12-601, subjecting violators to misdemeanor penalties and daily fines. Providing unlicensed HVAC services violates Md. Code Ann., Bus. Reg. § 9A-501, which similarly carries criminal misdemeanor sanctions and regulatory penalties.
  • Civil Filing Costs: If you sue the contractor in District Court (for claims up to $30,000), the filing fee is generally around $34 to $46. If the damages exceed that and you file in Circuit Court, the base fee is around $165.

How Long Does the Process Take?

Stopping an unlicensed contractor is immediate-you simply fire them. However, getting your money back takes time. Small claims court cases (for amounts under $5,000) can often be resolved in 2 to 4 months. If your losses are substantial and require a full trial in Circuit Court, the litigation process can take 12 to 18 months, especially if the scammer attempts to hide their assets.
