Can You Move Away and Rent Out Both the House and the ADU? Depends on a Line You Can't See

The sentence that stops the whole plan

Orange County's zoning code has a line in its accessory dwelling unit rules that says the primary dwelling or the ADU shall be occupied by the owner at all times. At all times. Not "for the first year." Not "until you get a permit." The county doesn't care which of the two buildings you sleep in — big house or little one — but one of the lights on that lot at night has to be yours.

So the move-away-and-rent-both plan dies right there, if your lot sits in unincorporated Orange County. That's Conway. That's Azalea Park, Pine Hills, Rio Pinar, Meadow Woods — big stretches of the map that feel like Orlando, get mail that says Orlando, and are not actually in Orlando.

And that's where this gets strange. Because if your lot sits inside the actual Orlando city limits, the rulebook changes completely. The city's ADU rules don't have that sentence. Orlando lets an ADU be rented on a standard residential lease, and the city doesn't require the owner to live on the property. Buy a house in the city, add an ADU, move to Tennessee, rent both units long-term — Orlando permits it. Two houses on the same street, a few blocks apart, can live under opposite answers to the exact same question. And you can't tell which rulebook you're under by standing in your driveway.

Why the county's version is harder to escape than it looks

Here's the part that surprises people who think they've found a workaround. The county rule isn't just "live there." It also says the property must qualify as homestead — your legal primary residence, the thing your homestead exemption hangs on.

And Florida tax law has its own opinion about what happens when you move away. Rent out all or substantially all of a home you've claimed as homestead, keep it rented long enough, and the state considers the homestead abandoned. You didn't fill out a form. You didn't ask for that. It just happens, the way milk goes bad whether or not you're watching it.

So in unincorporated Orange County the trap closes twice. Move away and rent both units, and you've broken the occupancy rule and dissolved the homestead status the ADU approval depends on. It's built so the two requirements catch each other.

A lot of people have been waiting for Tallahassee to fix this from above. A state bill in 2025 would have forced every local government to allow ADUs and banned exactly these owner-occupancy rules. It died in the legislature. So for now, there's no state law overriding your county or your city — the local code on your specific parcel is the whole ballgame. And the cities each wrote their own: Winter Garden, for one, has its own version that also expects the owner living on the property.

What tripped up the people who actually built one

Read through the comments under any video about renting out backyard units and you'll notice the questions aren't about construction. They're about what happens after.

Someone builds the unit and then discovers their HOA quietly adopted language banning ADU rentals years ago — and an HOA can say no even where the county says yes. Someone else asks how much their property taxes jumped once the second dwelling hit the appraiser's records, because a lot with two homes on it is worth more than a lot with one, and the tax bill notices. Another wants to know whether the well and septic out back can legally serve a second household, which in parts of unincorporated Orange County is a real question with a real answer that involves the health department.

And then there's the lease itself. The county built its ADU rules for neighbors, not weekenders — leases have to run long-term, think seasons rather than weekends, so the Airbnb version of this plan is off the table from the start. Inside Orlando, anything shorter than a month is its own separate fight under the city's home-share rules.

But notice what still works, even under the strict county rule. Renting the ADU while you live in the main house — that works. Moving into the ADU yourself and renting out the big house — that works too, and it's the version people forget. Your tenant gets the bigger place and pays the bigger rent, and you still satisfy the letter of the code, because the county never said which building had to be yours. The rule blocks absentee landlords. It doesn't block income.

So the first question isn't the floor plan

It's the parcel. Everything above — owner on site or not, homestead or not, lease length, even whether the county's Ready Set Orange pre-designed plans apply to you — flows from one boring fact: which jurisdiction's rulebook your lot answers to. City of Orlando, unincorporated county, Winter Garden, somewhere else. People plan the kitchen for months and never check the one thing that decides whether the whole rental math works.

That's the check worth doing before you sketch anything. Run your property through the ADU Fit Check — it looks at your actual lot and tells you what you're allowed to build there and what the rules around it look like. Takes a few minutes. Then design the kitchen.
