What Maryland law says about home improvement contractors
Maryland's Home Improvement Commission Act, codified at Md. Code, Real Prop. § 9-601 through § 9-609, is one of the most detailed contractor-protection frameworks in the Mid-Atlantic. It doesn't just set general standards of good conduct. It prescribes specific, enforceable requirements that every contractor must meet before they pick up a hammer on a Maryland property.
Under Md. Code, Real Prop. § 9-601, a contractor must give you a written contract that includes their name, address, Maryland Home Improvement Commission license number, a description of the scope of work, total price, payment schedule, start and estimated completion dates, and written warranty information. A contractor who hands you a one-paragraph work order and pockets your deposit has violated the statute before a single tool is examined.
Registration matters too, and it matters in a way that works in your favor. Under Md. Code, Real Prop. § 9-603, a contractor who is not registered with the Maryland Home Improvement Commission cannot bring a legal action to collect payment for home improvement services. That means an unlicensed contractor who abandons your kitchen remodel and threatens to take you to court is bluffing. They have no standing. You, on the other hand, can still pursue all available claims against them.
The deposit cap your contractor probably already violated
Before you start cataloging everything that went wrong on your job, check one thing first: how much did you pay upfront?
Under Md. Code, Real Prop. § 9-604, a home improvement contractor cannot require or accept a payment or deposit greater than one-third of the total contract price. If your roof replacement was quoted at $9,000 and the contractor took $5,000 before starting, they were over the cap the moment they cashed that check. The overage is recoverable regardless of whether the work was ever started.
The same statute says a contractor cannot demand final payment until the work is substantially complete. "Substantially complete" is not a term contractors get to define for themselves. Courts in Maryland have consistently interpreted it to mean the work is usable for its intended purpose, all major phases are done, and only minor punch-list items remain.
Two situations where this plays out in practice:
First, the contractor finishes about half the project, then sends a final invoice and refuses to return until it's paid. That's a violation. Final payment is not due on a half-finished job.
Second, the contractor abandons the project entirely after taking a deposit. The deposit, to the extent it exceeded one-third of the contract price, is recoverable on its face. Even the portion within the cap is recoverable if no work was performed for it.
Both of these fact patterns belong in a demand letter. Named statute. Specific dollar amount. Short deadline. Clear next step.
How long you have to act in Maryland
Maryland's statute of limitations for contractor disputes is four years. That clock starts running from the date the violation occurred, which is typically the date the contractor breached the contract, abandoned the project, or took money without performing.
Four years sounds generous. It isn't a reason to wait. Several things erode a strong claim over time:
Text messages get deleted. Contractors dissolve their LLCs. Bank records become harder to subpoena. Witnesses' memories fade. The contractor's insurance policy lapses. And if the contractor files a mechanic's lien, the window to respond narrows quickly.
Under Md. Code, Real Prop. § 9-601.1, a contractor who is not paid for labor or materials may file a mechanic's lien against your property within 90 days of ceasing work. Even if the contractor's claim is weak, a lien on your title creates problems if you're trying to refinance or sell. A demand letter sent before the contractor files puts you in a better position to challenge any lien they do file, because the record shows you disputed the debt in writing first.
Send the letter now. Four years is the limit, not the strategy.
What a Maryland homeowner can actually recover
The answer depends on what the contractor did and whether it rises to willful misconduct.
Actual damages. The money you paid for work that was not done, done defectively, or done in a way that required correction. Also includes the cost to hire a replacement contractor to finish or repair the job.
Deposit recovery. Any payment above the one-third cap under § 9-604 is recoverable outright. Deposits within the cap are recoverable if no work was performed or the contractor materially breached the contract.
Treble damages. Under Md. Code, Real Prop. § 9-609, if the contractor's violation was willful or in bad faith, a court can award three times actual damages. Willfulness doesn't require you to prove the contractor planned to defraud you from the beginning. Courts have found willfulness where a contractor repeatedly ignored completion deadlines, failed to obtain required permits, or pocketed a deposit with no intention of starting work.
MCPA statutory damages. The Maryland Consumer Protection Act, Md. Code, Com. § 13-101 et seq., prohibits unfair and deceptive trade practices. A contractor who misrepresents their license status, the scope of work, or the materials used may be liable for up to $1,000 in statutory damages per violation, on top of actual damages, plus reasonable attorney's fees if the violation is willful.
On a $4,000 dispute involving a willful violation, the realistic recovery ceiling looks like this: $4,000 actual damages, multiplied by three under § 9-609, plus up to $1,000 in MCPA statutory damages. Attorney's fees become leverage in settlement, not just a courtroom remedy.
Evidence that makes a Maryland contractor claim credible
A demand letter without documentation is a complaint. A demand letter with documentation is a legal notice. Contractors and their insurers know the difference.
Before you send anything, gather and organize:
The written contract. All pages, including any change orders, addenda, or text message exchanges where the scope was modified. If the contractor didn't provide a written contract as required by § 9-601, that failure is itself evidence of a statutory violation.
Proof of payment. Bank statements, cancelled checks, Venmo or Zelle records, or wire transfer confirmations. Document every dollar that changed hands and on what date.
The contractor's license status. Look up the contractor on the Maryland Home Improvement Commission's public database at mhic.maryland.gov. Print or screenshot the result. An unlicensed contractor gets named in the letter explicitly.
Photographs. Before the contractor started, during the work if you have them, and after. Time-stamped photos from your phone are often the most useful evidence in contractor disputes because they're harder to dispute than written descriptions.
Written communications. Every email, text, or voicemail where you asked about timeline, raised concerns, or requested a response. A pattern of unanswered messages is strong circumstantial evidence that the contractor knew they were in breach.
Estimates from other contractors. If you need to hire someone to complete or repair the work, get two written estimates before signing anything. Those estimates establish your actual damages with precision.
Writing a Maryland contractor demand letter that produces results
The goal of a demand letter is narrow: give the contractor one last, formal opportunity to resolve the dispute before a court does it for them. The letter works best when it is short, factual, and specific about the statute and the penalty.
Here's what your Maryland contractor demand letter should contain:
Identification. Your full name and address. The contractor's full legal name, business name, address, and MHIC license number (or, if they're unlicensed, the explicit statement that they lack a valid registration under § 9-603).
The contract facts. Date of the contract, total price, payment schedule, and what was promised. Attach the contract as an exhibit.
What went wrong. A numbered, chronological list of the violations: deposit taken above the one-third cap on a specific date, work abandoned on a specific date, required permits not obtained, contract terms not provided. Dates matter. Dollar amounts matter.
The statute. A direct citation to Md. Code, Real Prop. § 9-601, § 9-604, or § 9-609, as applicable. Also cite Md. Code, Com. § 13-101 if the conduct was deceptive. Don't describe the law in general terms. Quote it.
The demand. A specific dollar amount. "Return my $3,200 deposit and pay $800 for the remediation estimate from ABC Roofing" is better than "pay for all damages." Give the contractor a deadline of 10 to 14 calendar days.
The consequence. A clear, calm statement that if the demand is not met by the deadline, you will file in Maryland District Court for the principal, treble damages under § 9-609, MCPA statutory damages, and attorney's fees. Make sure the contractor understands that their unlicensed status, if applicable, bars them from counterclaiming.
Send by USPS Certified Mail so you have tracking and delivery confirmation. Keep a copy of everything.
If the contractor ignores your letter
Most contractors settle when they see the statute cited and the treble damages named. But if the deadline passes and you've received nothing, the next step is court. For claims up to $5,000, you can file a Maryland small claims case against a contractor in the District Court without a lawyer. Claims above $5,000 require Circuit Court, where the process is more formal.
Maryland District Court handles contractor disputes efficiently. The filing fee is modest, hearings are typically scheduled within 60 days, and judges who handle District Court cases see contractor disputes regularly. The record you built while preparing the demand letter is the same record you'll present to the judge.
What to expect after the letter goes out
USPS Certified Mail typically delivers within two to four business days. Once delivery is confirmed, the contractor's deadline clock starts.
In the first week, most responses fall into one of three categories: a payment offer, a denial with some explanation, or silence. Payment offers below your demand are negotiable, but don't accept less than actual damages without considering whether treble damages apply to your specific facts. A partial offer that ignores the penalty clause isn't a resolution.
A denial is not the end. It's a document. Save it. Anything the contractor puts in writing that misrepresents the facts or disputes the statute citation may become additional evidence of bad faith, which strengthens the willfulness argument under § 9-609.
Silence is also a document. If you've sent a properly addressed certified letter, confirmed delivery, and received no response by the deadline, a court will draw reasonable inferences from that silence. File promptly. Don't give the contractor time to dissolve the business entity or encumber the assets.
If the contractor responds with a mechanic's lien threat, don't panic. A contractor who is unregistered under § 9-603 has severely limited legal standing in Maryland courts, and a lien filed in bad faith can itself be the subject of a claim. Your demand letter, sent before any lien was filed, establishes that you disputed the debt in writing first.
