You framed the extra bathroom, ran the new circuit, added the extended lanai the homeowner begged for on a Tuesday afternoon — and now, four months later, they are refusing to pay for any of it. "I never agreed to that price." That is the moment Florida change order requirements stop being paperwork and start being the difference between a profitable job and a fight you might lose. If you build in Florida and you handle extras with a handshake, you are one unhappy client away from doing thousands of dollars of work for free.
This is the honest, builder-to-builder version of what Florida actually expects when the scope changes on a job — and what it costs when you get it wrong. Quick heads-up first: this is general information, not legal advice. Rules change and every job is different, so confirm the current requirements with the Florida Department of Business and Professional Regulation (DBPR), the Construction Industry Licensing Board (CILB), or a licensed Florida construction attorney before you rely on any of it.
What Florida change order requirements actually say
Here is the part that surprises a lot of contractors: Florida does not have one tidy statute that says "every change order must be signed in blood." What Florida has instead are a handful of rules that quietly punish you for doing extras the sloppy way.
Start with the lien law. Florida's construction lien statute (Chapter 713) defines "extras or change orders" as labor, services, or materials authorized by the owner and added to or deleted from the original contract. Read that again: authorized by the owner. If you cannot show the owner actually authorized the extra work, you are on shaky ground when you try to lien the property for it. A verbal "yeah, go ahead" from someone standing in the driveway is a lot harder to prove than a signed change order sitting in your file.
Then there is the money statute. Florida Statute 489.126 ("Moneys received by contractors") governs deposits and progress payments on residential work. If you collect more than 10% of the contract price up front, you generally have to apply for permits within 30 days and start the work within 90 days — unless the owner agrees in writing to a longer timeline. And if you take money for work and then fail to perform for any 90-day stretch without just cause, that is not just a civil headache. Depending on the dollar amount, 489.126 violations are prosecuted as anything from a first-degree misdemeanor to a first-degree felony. Change orders are exactly where this goes sideways: you collect for an upgrade, the schedule slips, the client gets angry, and suddenly a payment dispute has a criminal shadow over it.
Add licensing on top. The CILB and DBPR regulate how contractors operate in Florida, and mishandling contracts and payments is the kind of thing that shows up in complaints. None of this requires you to be a lawyer. It just requires you to write the change down and get a signature before the work happens.
The real cost of getting Florida change orders wrong
Let's agitate the wound for a second, because the abstract version never lands. Here is what "no signed change order" actually costs a Florida contractor:
You eat the work. The most common outcome is the simplest: the client refuses to pay for the extra, you have nothing signed, and rather than torch the relationship or hire a lawyer over $4,000, you write it off. That is margin straight off your bottom line — on a job you already thought was done.
Your lien gets weaker. Florida's lien law can be a powerful collection tool, but a lien for "extras" invites the owner to argue the extras were never authorized. Without a signed change order, you are asking a judge to take your word over theirs. Even when you eventually win, you have burned months and legal fees to collect money that a two-minute signature would have locked in.
The dispute compounds. Unpaid extras rarely stay small. They stall final payment on the whole contract, they sour the relationship so the client nitpicks your punch list, and they turn into online reviews that cost you the next three referrals. In Florida's tight residential market, a reputation for "surprise charges" is a slow bleed.
Deposit rules bite. Take a chunk of money for a big change, hit a supply delay, and blow past that 90-day window, and you have handed an angry homeowner a statute to wave at you. Most of these never become criminal cases — but "most" is a bad thing to bet your license on.

Almost every unpaid-extra story in Florida traces back to one of these five habits. Read them as a checklist of what not to do:
- The verbal go-ahead. "Just do it, we'll settle up later." You do it. Later never comes at your number. Under Florida's lien law, unauthorized-that-you-can't-prove is nearly as bad as unauthorized.
- The text-message change order. A thumbs-up emoji on your text is better than nothing, but it rarely spells out price, scope, and the new contract total. When the client claims the "$800" was "$300," a vague thread doesn't save you.
- Work first, paper later. Doing the extra and then chasing the signature flips all the leverage to the client. Once the lanai is poured, why would they sign for a number they can now argue down?
- No running total. Five little changes at $600 each, none of them written, and at closeout the homeowner swears the contract was fixed-price. If you can't show the revised contract value climbing change by change, you look like you're padding the bill.
- Collecting big deposits on changes without a written timeline. This is where 489.126 stops being trivia. Money in, no written schedule, a delay — and you've built the other side's case for them.
Notice the through-line: every one of these is fixed by the same cheap habit. Write the change down. Put a price and a new contract total on it. Get a signature before the crew touches it.
The right way: get it in writing, signed, before the work
Doing Florida change orders correctly is not complicated and it does not require a lawyer on retainer. A proper change order names the job and the original contract, describes the added or deleted scope in plain language, states the price (or a clear time-and-materials basis), shows the revised contract total, and gets signed and dated by the owner before the work starts. That's it. That single sheet is what turns "he said, she said" into "here's your signature."
You've got two solid, free ways to make that happen, and honestly either one beats a handshake by a mile. Pick whichever fits how you work.
If you like spreadsheets, grab the free Excel change order template. It's a professional, auto-calculating sheet: you enter the line items, and it works out markup, tax, and your new revised contract value automatically, with a built-in log so you can track every change on the job in one place. Print it, get it signed, keep it in the project file. For a Florida contractor who lives in Excel already, it's the fastest way to stop losing money on extras. You can download the free change order spreadsheet and use it on every job, no strings attached.

You fill in the change, hit send, and the homeowner signs from their phone in about a minute — no printer, no "I'll sign it tonight" that never happens. The revised contract total updates itself, and you've got a timestamped, signed record the moment they tap approve. That timestamp and signature are exactly the kind of owner authorization Florida's lien law cares about. It's built for exactly this problem, and it's 100% free to create a change order.
Both do the same essential job: they get the owner's authorization in writing before you spend a dollar on the extra.

A 60-second Florida change order checklist
Before your crew starts any extra work in Florida, run this:
- Is the change written down — scope, price, and revised contract total?
- Does it reference the original contract and the property?
- Did the actual owner (not a neighbor or a subcontractor) sign and date it?
- If you collected a deposit, is the new timeline in writing?
- Do you have a copy filed with the rest of the job records?
Five yeses and you've done more to protect yourself than most contractors in the state. Zero of them and you're gambling your margin on someone else's memory.
Frequently asked questions
Does Florida law require change orders to be in writing?
There isn't a single Florida statute that says every change order must be signed, but the practical answer is yes, always put it in writing. Florida's construction lien law (Chapter 713) only protects extras that were authorized by the owner, and a signed change order is the cleanest proof of that authorization. Written change orders also protect you under the payment rules in Florida Statute 489.126. When in doubt, get it signed before the work starts.
Can I file a lien in Florida for extra work without a signed change order?
Sometimes, but you're making it hard on yourself. Florida's lien law defines extras as work authorized by the owner, so if you can't prove authorization, the owner can dispute the lien and you may spend months and legal fees trying to collect. A signed change order removes the argument. It's far cheaper to get the signature up front than to litigate authorization later.
What is Florida Statute 489.126 and how does it affect change orders?
Section 489.126 governs money contractors receive on residential work. If you collect more than 10% of the contract price up front you generally must apply for permits within 30 days and start work within 90 days unless the owner agrees in writing to a longer period, and taking payment then failing to perform can carry criminal penalties. Change orders often involve new deposits, so putting the scope, price, and timeline in writing keeps you on the right side of it.
Is there a free Florida change order template I can use?
Yes. You can download a free Excel change order template that auto-calculates markup, tax, and your revised contract total and includes a log to track every change on the job, or use the free digital tool to send a change order the owner signs from their phone. Either one gives you the signed, written record that Florida contractors need. This is general information, not legal advice — confirm current requirements with the DBPR, the CILB, or a licensed Florida attorney before relying on them.
