How to File a Complaint Against a Maryland Contractor

When a licensed home improvement contractor in Maryland performs defective work, abandons a project, or engages in deceptive practices, state law provides structured complaint channels through the Maryland Home Improvement Commission (MHIC). Filing a formal complaint initiates an administrative process that can result in contractor discipline, license suspension, or financial recovery through the MHIC Guaranty Fund — a statutory remedy unavailable through civil court alone. Understanding how the complaint process is structured, which agency holds jurisdiction, and what evidence is required determines whether a complaint results in enforcement action or dismissal.

Definition and scope

A complaint against a Maryland contractor, in the regulatory sense, is a formal written allegation submitted to a state licensing authority asserting that a licensed contractor violated Maryland's Home Improvement Law (Maryland Code, Business Regulation Article, Title 8) or associated regulations. The MHIC, which operates under the Maryland Department of Labor, holds primary jurisdiction over complaints involving home improvement contractors licensed through the Maryland Home Improvement Contractor license program.

Scope of MHIC complaint authority:

• Home improvement work performed on residential property
• Disputes involving MHIC-licensed contractors
• Allegations of fraud, misrepresentation, abandonment, or defective workmanship
• Claims involving contractors who performed work without a required license

Outside the scope of MHIC complaint authority:

• Commercial construction disputes
• Contractor-to-contractor disputes (subcontractor vs. general contractor)
• Disputes with contractors licensed exclusively through other Maryland boards (e.g., the State Board of Master Electricians, the State Board of Plumbing)
• Federal or interstate contracting matters

For disputes involving electrical, plumbing, or HVAC work, the applicable licensing boards — covered under Maryland electrical contractor licensing, Maryland plumbing contractor licensing, and Maryland HVAC contractor licensing — each maintain their own complaint channels and disciplinary procedures. The MHIC does not adjudicate those categories.

How it works

The MHIC complaint process follows a defined administrative sequence. Complaints must be filed in writing and submitted to the MHIC through the Maryland Department of Labor (mdol.maryland.gov). The MHIC does not accept anonymous complaints; the complainant's identity is part of the official record.

Numbered complaint process steps:

1. Document the dispute — Gather the written contract (required under Maryland law for jobs over $500 per Md. Code, Bus. Reg. § 8-604), all payment records, correspondence, photographs of defective work, and any inspection reports.
2. Verify the contractor's license — Confirm whether the contractor held an active MHIC license at the time of the work. License verification is available through the Maryland Department of Labor's online license lookup.
3. Submit the written complaint — File the complaint form with the MHIC, attaching all supporting documentation. Complaints may be mailed or submitted in person to the MHIC office in Baltimore.
4. MHIC investigation — An MHIC investigator reviews the complaint, contacts the contractor, and may conduct a site inspection or request additional records.
5. Hearing or settlement — If the investigation identifies potential violations, the case may be referred to a formal hearing before the Commission.
6. Disciplinary action or dismissal — Outcomes range from dismissal (insufficient evidence) to license suspension, revocation, civil penalties, or referral for criminal prosecution under Md. Code, Bus. Reg. § 8-625.

Complainants seeking financial recovery may also apply to the MHIC Guaranty Fund, which can pay eligible claimants up to $15,000 per project and up to $75,000 per contractor (Md. Code, Bus. Reg. § 8-410).

Common scenarios

Three categories represent the majority of MHIC complaints filed by Maryland homeowners:

Abandonment or non-completion — A contractor accepts a deposit, begins work, and stops without completing the project or returning payment. This is the most frequently cited basis for Guaranty Fund claims.

Defective workmanship — Work is completed but fails to meet the standards specified in the contract or applicable building codes. Complaints in this category often require photographic evidence and, in contested cases, an independent inspection report. Maryland contractor permit requirements are relevant here — work performed without required permits may indicate a code compliance failure independent of the contract terms.

Unlicensed contracting — A contractor performs home improvement work in Maryland without holding a valid MHIC license. This violates Md. Code, Bus. Reg. § 8-301. Complainants in this scenario cannot access the Guaranty Fund, because Fund eligibility requires that the contractor held a valid license at the time of the contract.

Decision boundaries

The MHIC complaint process and a civil lawsuit are not mutually exclusive, but they serve different functions. The MHIC process is an administrative enforcement mechanism focused on contractor licensing discipline — it does not function as a substitute for civil litigation and does not award compensatory damages beyond Guaranty Fund limits.

Homeowners whose losses exceed the Guaranty Fund ceiling, or who seek remedies beyond license discipline, typically pursue parallel civil claims. Maryland contractor lien laws and contractor disciplinary actions are adjacent reference areas that bear on how enforcement outcomes interact with civil recovery.

For an overview of the contractor licensing and regulatory framework that governs these complaint rights, the Maryland Contractor Authority home provides the full landscape of licensing categories, board structures, and regulatory scope. Additional context on how the complaint process fits within Maryland's contractor service structure is available through Maryland contractor services in local context.

The Maryland Home Improvement Commission remains the primary enforcement body for residential contractor complaints, and its authority does not extend to commercial work, federal contracts, or disputes between contractors operating outside the home improvement licensing framework.
