Barrette Home Additions & ADU: The Fort Lauderdale Owner’s Guide
Barrette home additions and ADU construction in Fort Lauderdale typically runs $45,000 to $130,000 for a permitted addition, and $90,000 to $220,000 for a full detached ADU. Most owners discover a failed or failing Barrette addition when they see water intrusion at the tie-in point, a sagging roofline where the new structure meets the original home, or drywall cracks that open and close with the seasons. We handle the repair, correction, or complete redo of Barrette home additions and ADUs across Fort Lauderdale, and we’ll give you a written price before any tool gets pulled off the truck.
Key Takeaways:
- Barrette additions fail at the tie-in points first: roof connections, flashing, and foundation joints.
- Fort Lauderdale’s humidity and hurricane cycle punish wood framing and flashing faster than most climates.
- We stock common Barrette-compatible flashing, framing connectors, and structural hardware on the truck.
- Sawyer Remodel Fort Lauderdale is an independent contractor; we are not affiliated with Barrette.
Which Barrette Models This Applies To
Barrette’s product lines span several addition and ADU configurations, and the compatibility details matter more than most homeowners expect. Barrette additions fall into three general groups: stick-built room additions using Barrette’s framing and connector hardware, pre-engineered sunroom or bump-out kits, and modular ADU shells built to Barrette’s panelized specs. The connector plates, tie-downs, and flashing profiles differ between these lines, and they are not cross-compatible. If you have a Barrette sunroom or bump-out, the roof pitch and eave height dictate which transition flashing we use; a stick-built addition uses standard dimensional lumber with Barrette-specified Simpson or USP structural connectors. The panelized ADU shells use proprietary wall-to-roof and wall-to-floor channels that we match by measuring the panel thickness, which runs 4.5 to 6.5 inches depending on the insulation package Barrette specified at the time of manufacture.
Here is the gotcha most owners hit: the visible label on the inside of the door frame tells you the model year, not the hardware revision. Barrette changed its flashing profile in 2019, and a 2020-model shell can carry 2018-spec flashing if the original dealer cleared old inventory. We verify actual measurements on site rather than trusting the sticker. For OEM versus aftermarket, Barrette-branded flashing and channels are sometimes the only correct fit on the panelized shells; for standard dimensional lumber additions, a quality aftermarket structural connector from Simpson or USP does the same job and often exceeds the original spec. We tell you which one applies and why before you pay for anything.

Signs Your Barrette Home Additions & ADU Is Failing
- Water staining at the ceiling-to-wall joint where the addition meets the original house. This is the most common failure point on Barrette additions in Fort Lauderdale. The flashing at the tie-in loses its seal, and driven rain from afternoon thunderstorms works its way in. Left alone, it rots the top plate and the rafter tails.
- Drywall cracks that open wider in summer and close slightly in winter. South Florida’s wet-dry cycles swell and shrink the framing. If the crack exceeds about 1/8 inch and recurs after patching, the addition is moving independently from the main structure, which points to a foundation or connector issue rather than a cosmetic drywall flaw.
- A roofline that dips or sags at the seam between the addition and the original roofline. That sag means the structural splice is no longer transferring load the way Barrette’s original engineering assumed. We see this most often on additions where the original installer cut into the existing roof without a proper ridge beam or header.
- Doors or windows in the addition that stick, bind, or no longer latch. Racking or settling has thrown the openings out of square. In slab-on-grade Florida construction, this often traces back to undersized footings or a missing tie-down at the sill plate.
- Musty odor or visible mold at the baseboard line on exterior walls. The wall assembly is trapping moisture, typically because the vapor barrier or weep system was installed incorrectly for a humid coastal climate. Barrette’s northern-spec wall details fail quickly in Fort Lauderdale without a modified drainage plane.
Replacement Cost & What’s Included
In Fort Lauderdale, correcting or rebuilding a Barrette home addition runs $45,000 to $130,000 installed, with full ADU ground-up construction at $90,000 to $220,000. The spread depends on what failed: a flashing and drywall correction at the tie-in might land at the lower end, while rebuilding a foundation or reframing a failed roof splice pushes toward the top. Every quote we write separates materials, labor, and permitting so you see exactly where the money goes. Permitting in Fort Lauderdale adds real line items: building permit fees, impact-window or door compliance where applicable, and inspections. We pull the permits, we schedule the inspections, and we do not write change orders when the inspector asks for something the original plan missed. Your written price is the price, period.
Every Barrette addition or ADU repair we do carries the 365-Day Done Right Promise in writing. If something we touched fails inside that year, we come back and make it right at no charge. Labor and the parts we supply are covered. That is not a verbal handshake; it is in the contract.

Some things a Barrette addition owner can safely check: water stains, visible mold, sticking doors, cracks wider than a dime. Document them, take photos, and watch whether they change after heavy rain. What is not a DIY job is anything structural. Cutting into a load-bearing wall, re-flashing a roof tie-in, jacking a sagging roofline, or reworking a foundation connection without an engineer’s direction will cost you more than you save, and it can put you and your family at risk. Florida building code exists because hurricanes and humidity do not forgive shortcuts. If your Barrette addition shows any of the failure signs above, the fastest safe move is a professional assessment.
Call us at (754) 354-7423 and we will schedule a time to look at it. Luca Romano walks the site personally on structural jobs, and you get a written assessment and a written price before anything gets taken apart.
FAQs
A properly installed Barrette addition in Fort Lauderdale should last 30 to 50 years structurally, but the tie-in flashing and exterior seals typically need replacement every 10 to 15 years because of South Florida’s constant heat, humidity, and storm-driven rain. If your addition is failing before the 10-year mark, the original install likely skipped a step. Call (754) 354-7423 and we’ll inspect it and give you a straight answer.
Yes, in most cases a failing Barrette addition can be repaired if the framing, foundation, and roof structure are still sound; we fix flashing, refasten connectors, re-square openings, and replace water-damaged drywall and trim without a full teardown. Full rebuilds are only necessary when structural rot or foundation movement has compromised load-bearing members. Call (754) 354-7423 for a free assessment and a written scope of work.
A typical flashing and drywall correction at the tie-in takes 3 to 5 working days; a structural repair to the roof splice or foundation can run 2 to 4 weeks depending on permits and inspections, and a full ADU ground-up build in Fort Lauderdale runs 4 to 8 months from permit to final. We give you a schedule in writing before we start, and you get photo updates throughout. Call (754) 354-7423 to talk through your specific timeline.
We stock the common Barrette-compatible flashing profiles, Simpson and USP structural connectors, and standard dimensional lumber fasteners on the truck, and we can source Barrette-specific channel and panel hardware within a few days from our suppliers.
