AfterFast, Reliable Home Additions & ADU Across Southeast Arcadia
If you’re planning a Home Additions & ADU project in Southeast Arcadia, the honest answer is this: most jobs here run $45,000 to $130,000 for an addition, and $90,000 to $220,000 for a full detached ADU. That’s the market, and you should know it before anyone steps foot on your property. Barrett & Sons Construction has been building in DeSoto County long enough to know every wrinkle the local ground, the codes, and the pre-2004 housing stock will throw at your project. Tom Barrett answers his own phone, writes every scope and allowance on paper before work starts, and stands behind the whole thing with a written 90-Day Done Right Promise. Call us at (877) 610-1318 and we’ll come out, walk the site, and give you a real number.
Why Barrett & Sons Construction Is Southeast Arcadia’s Preferred Home Additions & ADU Company
We’re not a franchise. Tom Barrett founded this company in 1998, and his sons run the crews that work in Southeast Arcadia. When you call the office, a live person picks up – 24 hours a day, seven days a week – and you’ll never get routed to an out-of-state call center. Your estimate comes from someone who’s walked the jobsite, not a computer spitting out square footage numbers.
Southeast Arcadia is a market where the split in housing stock makes every project different. On one street you’ve got a 1960s wood-frame cracker-style house that rode out Hurricane Charley. Next door is a post-2004 rebuild on an engineered slab with impact windows. On the next lot, a manufactured home on blocks with an old addition tacked on that was never permitted. We’ve worked on all three, and we know what each one needs before the first wall comes open. Tom publishes his name, his address, and his license number – you can look it all up before you sign anything. Most of our Southeast Arcadia customers tell us they’d rather pay a fair price to a crew they’ll see again at the hardware store than roll the dice on a trunk-slamming crew from two counties over.
Our Home Additions & ADU Services in Southeast Arcadia
ADU Design & Permitting
A detached ADU in Southeast Arcadia almost always starts at the permit counter, and the conversation there is shaped by where your lot sits. If you’re east of the Peace River, the flood zone designation can push your floor elevation, your septic setback, or your drainage plan into a full engineering package. We handle the design, the plans, and the permit pull – and we write every allowance down before the county reviews anything. No surprises at the end.
New Detached ADU
New detached ADUs in Southeast Arcadia typically run $90,000 to $220,000 depending on size, finishes, and site work. The biggest local variable is the high water table: a flat, low-lying lot near the Peace River can turn a straightforward slab into an engineered fill project with drainage swales. We price that up front, not as a “discovery” later. Our crews pour foundations that pass inspection the first time because we’ve been doing it here since 1998.
Garage Conversion ADU
Converting an existing garage in Southeast Arcadia runs $30,000 to $80,000, but the pre-Charley stock comes with a catch: many older garages have roof decking nailed at 6-inch spacing and framing that doesn’t meet current wind-load codes. You likely won’t be forced to re-roof the entire house, but the converted space itself will need its own structural upgrades. We tell you that in the estimate, in writing, before you sign.
Junior ADU & Interior Conversion
A junior ADU carved out of an existing home is the most affordable path for Southeast Arcadia homeowners who want rental income or a private space for an aging parent. These projects often expose the same hidden conditions as any addition: cloth-jacketed wiring, rotted sill plates from decades of water-table wicking, or framing that predates Florida’s post-Charley wind-load standards. Our scope of work includes those line items up front, because we know they’re going to be there.

Trusted Brands We Service in Southeast Arcadia
You won’t find mystery-brand materials on a Barrett & Sons job. For bathrooms we install Schluter waterproofing systems and Grohe fixtures – brands you can look up, with published specs and warranties that hold up in Florida humidity. For roofing on additions, we carry GAF systems rated for the wind exposure zones Southeast Arcadia sits in. When you sign with us, the material allowances name the manufacturer. That means you know exactly what you’re paying for before the first delivery shows up.
Common Home Additions & ADU Problems We See in Southeast Arcadia Homes
- Pre-Charley roof decking at 6-inch nail spacing. Most surviving pre-2004 homes in Southeast Arcadia have roof decking that no longer meets the 6/6 nailing pattern required by current Florida Building Code. When an addition ties into that roofline, the permit almost always triggers bringing the entire assembly up to code – and we plan for that cost up front.
- High water table near the Peace River. The river overflows during heavy rain events, and the ground on the southeast side holds water. A slab addition that looks simple on paper can require engineered fill, perimeter drainage, and a revised pad elevation before the county will sign off.
- Septic systems that can’t take the new bedroom. A new ADU with a kitchen and bath means more flow to the drain field. In rural DeSoto County, many older systems are undersized for an added dwelling unit, and the health department may require a full replacement before the permit closes. That’s a $10,000 to $25,000 line item you need to know about before you buy the materials.
- Unpermitted additions from the 1970s and 80s. Southeast Arcadia is full of enclosed porches and tacked-on rooms that were never pulled through the county. When we tie a new addition into one of those, the inspector will look at everything – and the old work comes under current code. We write that possibility into the allowance schedule so you’re never blindsided at inspection time.
What a Home Addition or ADU Permit Will Expose in a Pre-Charley Southeast Arcadia Home
Here’s the thing nobody tells you until the wall is open. Because so many Southeast Arcadia homes are pre-2004 survivors of Hurricane Charley, opening up a wall for an addition almost always exposes roof decking nailed at 6-inch spacing and framing that predates Florida’s post-Charley wind-load codes. That condition – not your new square footage – is what triggers mandatory structural upgrades before a permit can close. It’s not optional, and it’s not our call; the inspector who signs your permit works for you, and he’s enforcing current code. We have built our entire estimating process around this reality. We inspect first, we write the likely upgrades into your contract as allowances before the walls open, and if we find something bigger, you get a written change order with a fixed price before we touch anything. An allowance that isn’t on paper is a surprise waiting for a date. So we put it on paper.
On a room addition off a 1960s cracker-style home near the Peace River, our crew found the existing subfloor had rotted from years of high water-table wicking, and the original wiring was cloth-jacketed aluminum. We wrote the scope of work to include a full rewire of the affected circuit, brought the new roof assembly to the current 6/6 nailing pattern, and priced the unforeseen floor repair as a line-item allowance. The homeowner approved the change order before we touched the joists. That’s how we work in Southeast Arcadia.

FAQs - Home Additions & ADU in Southeast Arcadia
The short answer is: not always, but usually where the addition ties in. Florida’s post-Charley code requires a 6/6 nailing pattern on roof decking, and most surviving pre-2004 homes in Southeast Arcadia have 6-inch spacing. The inspector will typically require the new portion of roof – and often the tie-in area – to meet current wind-load standards. That may mean re-nailing or re-sheathing a section of your existing roof, but it rarely means a full tear-off of the entire house. We write that into your allowance schedule before work starts so you know the maximum you’ll pay. Call (877) 610-1318 for an exact answer on your roof.
It can change everything about your slab design. The river overflows during heavy rain events, and the southeast side of town has a water table that pushes up against foundations. If your lot falls in a mapped flood zone, the county will require an engineered fill plan, a raised pad elevation, or a full drainage design before issuing the permit. On some lots we add an extra $15,000 to $30,000 for the dirt work and engineering. We verify the flood designation before we quote, so your first number is your real number. Call (877) 610-1318 and we’ll pull the flood map for your exact parcel.
It’s a one or two page written document with the new scope, the added line items, and the exact dollar amount. It’s signed by you before we make the change. No verbal “oh by the way” passing between crew members. When we found rotted subfloor and cloth-jacketed aluminum wiring on a room addition near the Peace River, the homeowner got a written change order covering the rewire and the floor repair – and approved it before we touched a joist. If we can’t put it on paper, we don’t do the work. That’s the whole system.
You can, but expect structural upgrades. A pre-2004 detached garage in Southeast Arcadia likely has roof decking nailed at 6-inch spacing, undersized headers over the door openings, and a slab that may not meet current elevation requirements if you’re near the flood plain. The conversion space will need to come up to current Florida Building Code before the county issues a certificate of occupancy. Budget $30,000 to $80,000 total, with a good portion of that going to code remediation rather than finishes. We’ll tell you the split in writing before you commit. Call (877) 610-1318 for a free garage assessment.
Because in Florida a sunroom is a structural addition, not a patio toy. The roof system on a sunroom carries wind load, the glazing must meet impact or wind-load standards, and the foundation tie-down matters during a hurricane. DeSoto County enforces this strictly, especially after Charley. A screened enclosure with no roof is treated differently than a glass sunroom with a roof attached to your house. Call (877) 610-1318 and we’ll tell you exactly what your sunroom project triggers at the permit counter – and exactly what it’ll cost.
