Designer, Builder, or Lead-Gen Site: Which 'ADU Company' Did You Actually Call?

You looked up "ADU builder near me," filled out a form, and hit send. Then your phone lit up — five calls in two days, and half of them wanted to talk about your credit, not your backyard. So which one did you actually reach: somebody who builds the thing, or somebody who sells your phone number? Turns out "ADU company" means three completely different businesses, and only one of them is ever going to pour a slab.

Same three words, three different businesses

There's the designer — draws the plans, hands you a set of drawings, and that's where their job ends. There's the builder — a licensed contractor who pulls the permit and actually stands in your yard while it goes up. And there's the third one, the one that confused you: a website that looks exactly like a builder but has never touched concrete in its life. It's a form wearing a builder's clothes.

You fill it out, it sells what you typed to a handful of other companies, and just like that, you're the product. The reason you couldn't tell them apart is that all three use the same words — "your ADU partner," "get a quote," a smiling stock-photo couple who have clearly never met your zoning district. From your driveway they look identical. The difference only shows up in what happens after you hit send.

The tell that you're talking to a form, not a foreman

A funnel gives itself away fast once you know where to look. Try to find a real address — an actual place in Orange County you could drive to. If the only thing that exists is a contact form and a stock photo, that's the sign. Look for a license number, too; a Florida contractor carries one and shows it off, because it's genuinely hard to get. A form has nothing to show, because it isn't building anything.

Then notice what the callbacks are about. A real builder wants to talk about your lot — your setbacks, whether the place is your homestead, how the utilities would run out back. A lead broker wants to talk about financing before anyone has measured a single thing, because the loan is where their cut lives. That's the exact moment it stops feeling like a contractor and starts feeling like a mortgage company. You're not imagining it. That is the whole business model.

One question sorts all three: who pulls the permit?

Here's the question that cuts straight through it. Ask whoever you're talking to: who pulls the permit, and what's the license number on it? In Orange County that permit is a real, specific thing, not a formality.

If your place sits in unincorporated Orange County — say a lot out past Rio Pinar or Meadow Woods — an ADU usually comes in as a special exception, tied to your main house being your homestead, and capped so it stays the smaller building on the property. Inside the City of Orlando the rulebook is different again; a neighborhood like Azalea Park or Conway plays by the city's zoning, not the county's. The county even runs a program called Ready Set Orange, a short menu of pre-drawn plans a building reviewer has already signed off on — but it only works in unincorporated Orange County, so plenty of folks who get excited about it turn out to live one street on the wrong side of a city line.

A designer can't answer the permit question, because they don't pull it. A form can't answer it, because it's never seen your lot. A real builder answers in one breath and can point you at a project going up in Winter Garden or Pine Hills this week. And you can check any Florida license yourself on the state's DBPR lookup before you ever pick up the phone.

So before you fill out one more form

The catch with sorting this out by calling five companies is that you become five companies' lead in the process — and now your phone won't stop for a month. There's a quieter way to start.

Figure out first whether your own lot can even hold an ADU — city or county, your zoning, homestead status, the size that would actually fit back there — before you hand your number to anyone. That's what the ADU Fit Check is for. You answer a few things about your property and where it sits, and you find out where you really stand instead of guessing from a search result. If it's a go, you walk in already knowing which door you're knocking on, and nobody's selling your name down the street while you do it.

Start with the Fit Check, and let the backyard question come before the phone starts ringing.

Common questions

How do I tell if an "ADU company" is an actual builder or just a lead-generation site?

Look for the things a real builder has and a form doesn't: a physical address in the area you could drive to, a Florida contractor license number shown openly, and photos of actual projects they can let you visit. If the site is mostly a contact form and stock imagery, and the first callback pushes financing before anyone's looked at your lot, you're on a funnel that resells your info, not talking to the crew that would build it.

Can I build an ADU on my lot in unincorporated Orange County?

Often yes, but it's conditional. In unincorporated Orange County an accessory dwelling unit is generally allowed as a special exception in residential zoning, the main house has to qualify as your homestead, and only one ADU is permitted per lot. Size is capped so the ADU stays smaller than the primary home. Your zoning district and lot specifics decide it, so confirm your parcel before you commit to anything.

Is the City of Orlando different from Orange County for ADUs?

Yes, and it matters which side of the line you're on. Neighborhoods inside Orlando city limits, like Azalea Park or Conway, follow the city's zoning code, which permits detached ADUs by-right in its single-family residential zones without an owner-occupancy requirement. Unincorporated Orange County uses a different process and its own size and homestead rules. Same county map, two separate rulebooks — check which one governs your address first.

What is Ready Set Orange, and can I use it?

Ready Set Orange is an Orange County program that offers a short menu of pre-designed ADU and starter-home plans already reviewed against the Florida Building Code, so you can skip straight toward permitting. The catch is that it only applies in unincorporated Orange County — not inside the City of Orlando. It's drawn hundreds of applications since it launched, but if your lot is inside a city limit, you'll be building a different way.

How do I check whether a contractor is actually licensed in Florida?

Use the state's license lookup run by the Department of Business and Professional Regulation (DBPR). Search by the company or individual's name or license number and confirm the license is active, matches the type of work — general or residential contractor — and has no open disciplinary action. Do this yourself rather than taking a screenshot's word for it; a genuine builder will hand you the number and expect you to check it.
