Maryland change order requirements: 6 costly errors

You are three weeks into a kitchen job in Towson. The homeowner walks in, points at the peninsula, and says she wants it two feet longer with a waterfall end. You nod, you build it, and you add $4,800 to the final invoice. She refuses to pay it. Now you are learning the Maryland change order requirements the expensive way — in a Guaranty Fund claim file, with an investigator asking you for a signed document you never created.

That is the part contractors miss about Maryland. This is not a state where a handshake quietly works out in your favor. Maryland's Home Improvement Law was written to protect the homeowner, and the Maryland Home Improvement Commission (MHIC) runs a Guaranty Fund that pays homeowners out of a pot funded by licensed contractors like you — and then comes after the contractor to get it back. Your paperwork is the only thing standing between you and that process.

Quick disclaimer before we go further: this is general information, not legal advice. Requirements change and vary — confirm the current rules with the Maryland Home Improvement Commission or a licensed attorney before relying on them.

What Maryland change order requirements actually say

Start with the contract itself, because a change order is just an amendment to it. Under Maryland's home improvement contract statute (Business Regulation § 8-501), every home improvement contract has to be in writing and legible, has to clearly describe each document it incorporates, and has to be signed by each party. It also has to spell out specific things: your name, address, phone number and MHIC license number; the license number of any salesperson who sold the job; the approximate dates work will begin and be substantially completed; a description of the work and the materials; the agreed price and payment terms; and a notice pointing the homeowner to the Commission.

Read those elements again with a change order in mind. An extra changes the description of the work. It changes the agreed price. It usually changes the completion date. MHIC's own guidance to homeowners is that amendments and change orders for additional or different work should be in writing and signed by both the homeowner and the contractor — and when MHIC investigates a Guaranty Fund claim, the documents it asks for are the contract, the change orders, and the cancelled checks. If you cannot produce a signed change order, the extra work effectively did not happen as far as the file is concerned.

One more thing on money: MHIC is clear that a contractor cannot take more than one-third of the contract price as a deposit, and cannot accept any payment at all until the contract is signed. Contractors routinely forget that logic applies to extras too. Collecting a deposit for a $12,000 addition that only exists as a text message is a bad position to be in.

The 6 change order mistakes that get Maryland contractors burned

1. The verbal go-ahead

"Just do it, we will square up at the end." That sentence has cost Maryland contractors more money than bad estimating ever has. Verbal extras are unenforceable in practice because you cannot prove the scope, the price, or the approval. The homeowner remembers a "small tweak." You remember four extra days of labor and $2,100 in millwork. There is no document to break the tie, and you are the one holding the unpaid invoice.

2. Letting your foreman or salesperson approve it

This one is written directly into Maryland law and almost nobody knows it. Section 8-501(e) says a salesperson, agent or employee of a contractor may not make a change in a home improvement contract for an owner. So when your lead carpenter shakes hands with the homeowner on a $6,000 bathroom upgrade, that is not a change order — it is a conversation. You are exposed twice: you have unbilled work, and you have a homeowner who genuinely believes it was approved by "the company."

3. A trail of texts instead of a signed document

Texts feel like proof. They are usually the opposite. A thread of messages shows a discussion, not an agreement to a defined scope at a defined price by a defined date. Half the exchange is voice notes and thumbs-up emojis. When an MHIC investigator or a District Court judge asks what exactly was agreed and for how much, "she texted back OK" is a weak answer compared to a one-page document with a signature and a date on it.

4. Burying the extra in the final invoice

The single fastest way to turn a happy client into a complaint. Nobody enjoys finding out at the end that the job costs $9,000 more than the contract said. That is the moment homeowners call MHIC, file a complaint, and stop paying the balance — including the money you legitimately earned on the base contract. A $4,000 argument becomes a $40,000 standoff.

5. Not restating the revised contract total and completion date

Maryland requires the contract to state the agreed price and the approximate completion dates. A change order that only says "add tile to laundry, $1,450" leaves both of those unresolved. Do the math on the page: original contract, plus or minus this change, equals the new total. Add the days. It stops the "I thought that was included in the price" argument dead, and it gives you a defensible schedule if the job runs long.

6. Taking money for work that has not been papered

Deposits on extras collected before the change order is signed put you in the worst possible position: you are holding the homeowner's money for work that has no written scope. If the relationship breaks down, that payment is the first thing that gets pointed at. Sign first, invoice second. Always.

Why sloppy paperwork hurts twice in Maryland

Most states let a change order dispute stay a private argument between you and the client. Maryland adds a second layer. The MHIC administers a Guaranty Fund that reimburses homeowners for actual loss caused by a licensed contractor's unworkmanlike, incomplete or abandoned work. The maximum recovery is $30,000 per claimant, or the amount the homeowner actually paid you, whichever is less, with a $250,000 cap across all claimants for the same contractor. Homeowners have three years from when they discovered (or should have discovered) the loss to file.

Here is the part that should get your attention. If the Fund pays out on a claim against you, you are responsible for reimbursing it — plus 10% interest per year — and your MHIC license stays suspended until you do. A dispute over an $8,000 extra can end with your license out of action, which means every other job on your board stops too.

The flip side is that documentation wins these files. MHIC asks claimants for the contract, the change orders and proof of payment, and claims that cannot be validated get dismissed without a hearing. Claims built on work that sits outside the scope of the original contract are on shaky ground. A contractor with a clean stack of signed change orders showing exactly what was added, when, at what price, and with whose signature, is a contractor who is very hard to pin down. That stack is the whole game.

The right way to handle Maryland change order requirements

None of this needs to be complicated. It needs to be consistent. Every change gets its own document, before the work starts, with a signature on it. There are two free ways to do that, and the right one depends on how you actually work.

If you like a spreadsheet. If your office runs on Excel and you want a document you can print, email as a PDF, and file on the job folder, use our free Excel change order template. It lays out line items, labor, materials, markup and tax, calculates the revised contract value automatically, and includes a change order log so you can see every extra on a job at a glance. Fill it in on the truck, print it, get the homeowner to sign it, scan it. It costs nothing and it works offline. For a lot of small remodelers that is genuinely all they need.

If you want it signed from a phone. If chasing printed paper is the reason your change orders never get signed, use the free ChangeOrdersPro tool instead. You type in the change, hit send, and the homeowner opens a link and signs it on their phone in about 30 seconds — time-stamped, with the revised contract total worked out for you. The signed copy lands in your email and stays on the job record. Same document discipline, no printer, no "I will sign it next time I am on site." It is also completely free, and if you are wondering where the catch is, we explain that on our pricing page.

Plenty of contractors use both — the free change order spreadsheet for pricing the work in the office, and the digital version for getting the signature on site. Whichever you pick, pick one and use it every single time. The change order you skip is always the one that turns into the dispute.

A 60-second checklist for every Maryland extra

Before anyone picks up a tool on additional work, your change order should show:

1. Your business name, address, phone and MHIC license number.
2. The project address and a reference to the original signed contract.
3. A plain description of the added or changed work and the materials being used.
4. The price of the change, broken out so it does not look like a guess.
5. The revised contract total — original price, plus or minus this change, equals the new figure.
6. Any change to the completion date, in days or a new approximate date.
7. The date, and signatures from both you and the homeowner — not a rep, not a foreman.

Seven items. Two minutes. It is the cheapest insurance in the business, and it is the difference between a contractor who gets paid for extras and one who eats them. If you want to see how other states compare, our change order requirements by state guide covers the rest, and the blog has more on pricing, markup and getting signatures fast.

Frequently asked questions

Do change orders have to be in writing in Maryland?

Maryland's home improvement law requires the contract itself to be in writing, legible and signed by each party, and to state the work, the materials, the agreed price and the approximate completion dates. Because a change order alters those terms, MHIC guidance is that amendments and change orders should be in writing and signed by both the homeowner and the contractor. Practically, an unsigned extra is very hard to enforce or defend.

Can my foreman or salesperson sign a change order for the company?

Maryland Business Regulation section 8-501(e) states that a salesperson, agent or employee of a contractor may not make a change in a home improvement contract for an owner. Treat change order approval as something only the contracting party handles, and make sure your crew knows not to agree to extras on site.

Is the free Excel change order template suitable for Maryland jobs?

Yes. The free Excel change order template gives you a written, signable document with line items, the revised contract total and a change order log. Add your MHIC license number and a reference to the original contract, and it covers the information a Maryland change order should show. Download it free and use it on any project.

What happens if a homeowner files an MHIC Guaranty Fund claim against me?

MHIC investigates using the contract, change orders and proof of payment supplied by the homeowner. Recovery is capped at $30,000 per claimant (or the amount the homeowner paid you, whichever is less), with a $250,000 cap across all claimants for one contractor. If the Fund pays, you must reimburse it plus 10% interest per year, and your license stays suspended until you do.

Is this legal advice?

No. This is general information, not legal advice. Requirements change and vary — confirm the current rules with the Maryland Home Improvement Commission or a licensed attorney before relying on them.
