AfterFast, Reliable Home Additions & ADU Across Dania Beach
A full home addition in Dania Beach typically runs $45,000 to $130,000, and a detached ADU usually lands between $90,000 and $220,000. Those numbers reflect something most contractors won’t tell you: this city sits directly under Fort Lauderdale-Hollywood International Airport’s approach surfaces. That means a second story, a rooftop HVAC unit, or even a crane lift on the wrong block requires FAA Form 7460-1 clearance before the city will sign your permit. Barrett & Sons Construction handles that paperwork as part of the job. If you’re planning a room addition, garage conversion, or new detached ADU in the 33004 ZIP code, call (877) 610-1318 for a free estimate.
We’re the owner-operated crew that shows up when we say we will. Tom Barrett founded this company in 1998, and his sons run the crews serving Dania Beach today. You’ll talk to a live person when you call, not a voicemail box in another state.
Why Barrett & Sons Construction Is Dania Beach’s Preferred Home Additions & ADU Company
We’ve built in the neighborhoods east of US-1 where the salt air eats zinc-plated hardware within a few years. We know the blocks west of Federal Highway where king tides push water over curb lines in October. That local knowledge changes what we specify, what we flag for the inspector, and what we write into your change orders. There’s a difference between a contractor who’s built here and one who just types “Dania Beach” into a GPS. Our Home Additions & ADU team works from plans that consider FAA clearance, HVHZ wind ratings, and flood elevations on day one, not after the rough-in hits a wall.
We don’t dispatch strangers. The crew members on your job carry the Barrett & Sons name, they’re background-checked, and Tom Barrett is on-site most days. Every price change arrives in writing before a single nail moves. If something isn’t done right, the 90-Day Done Right Promise means one call brings Tom back to make it right. Ask anyone on your street, or look up the license number yourself. We publish it.
Our Home Additions & ADU Services in Dania Beach
ADU Design & Permitting
Before concrete pours in Dania Beach, your ADU design has to clear three distinct layers: city zoning, FAA obstruction review if the structure adds height, and FEMA flood elevation for anything on grade. We work that permitting chain in the right order. A detached ADU on a low-lying 33004 lot needs finished floor elevation set against current FEMA maps, not the outdated ones many homeowners have in a drawer. We pull the permit, schedule the inspections, and stand next to the inspector when he signs off.
New Detached ADU
A new detached ADU in Dania Beach runs $90,000 to $220,000, and the spread depends on what the lot gives us. Salt-air corrosion means we won’t spec standard zinc-plated fasteners or cheap aluminum railing. We write hot-dipped galvanized or stainless hardware into the scope before we start, because replacing rusted connectors ten years from now costs twice what the right fasteners cost today. The permit inspector isn’t our enemy. He works for you, not for us, and we like him there.
Second Story Additions
Adding a second story in Dania Beach isn’t just a structural question. In most of the city it’s an aviation question. Runway protection zones and approach surfaces extend over residential streets in the 33004 ZIP code, so a vertical addition of roughly 35 to 50 feet may require FAA Form 7460-1 before the city issues a building permit. We file that form, track the response, and sequence the crane schedule around whatever the FAA approves. Skip that step and you’ll get a stop-work order after rough-in. We won’t let that happen on our watch.
Garage Conversion ADU
Converting an existing garage in Dania Beach runs $30,000 to $80,000, and it’s usually the fastest path to a rentable unit because it rarely adds vertical height. That means no FAA review unless you’re putting rooftop equipment on the structure. The bigger issue is what’s already in the walls. Older Dania Beach garages often have 1960s and 1970s framing, zinc-plated hardware that’s been rusting in salt air, and slab elevations that predate current flood maps. We inspect, and when we find something the scope didn’t cover, you get a written change order before we touch it. An allowance that isn’t on paper is a surprise waiting for a date.

Trusted Brands We Service in Dania Beach
We carry materials you can look up. Techo-Bloc and Cambridge Pavers for hardscape and paver work around a new ADU. For structural hardware and connectors, we specify hot-dipped galvanized Simpson products, which is what the salt air in Dania Beach demands. When the job calls for outdoor living space attached to an addition, we use belgard or Techo-Bloc pavers with sealed joints that hold up to the marine environment. We’re not installing mystery brands off a van. If you can’t find it in a catalog, we don’t put it on your property.
Common Home Additions & ADU Problems We See in Dania Beach Homes
- Corroded hurricane straps from the 1970s: In the older 33004 neighborhoods east of US-1, original zinc-plated hurricane straps are often flaking from decades of salt air. On a home addition in that area, our rough-in uncovered exactly that, so we wrote a change order to swap them for hot-dipped galvanized Simpson H2.5A connectors before inspection sign-off. The permit office’s third-party inspector confirmed the corrosion before the walls closed. That’s the permit doing its job, not red tape.
- Slab-on-grade ADUs set too low for king tides: Low-lying blocks of Dania Beach see king-tide flooding that can top the finished floor elevation on a slab-on-grade ADU if the design used an outdated FEMA flood map. The result is a new unit that’s non-compliant and uninsurable. We check current flood maps before we pour.
- FAA height violations on second stories and rooftop units: Adding a second story or rooftop HVAC without filing FAA Form 7460-1 stalls the permit and can trigger a stop-work order after rough-in. The airport’s obstruction surfaces extend over residential streets across the whole city. We file that form early.
- Inland-spec fasteners that rust within a decade: Dania Beach sits between the Intracoastal and the Atlantic, and salt-air corrosion eats zinc-plated roof fasteners and railing bolts within a few years. An addition built with inland-spec hardware develops rust streaks and loose connections long before the roof fails. We spec stainless or hot-dip galvanized from day one.
Pricing for Home Additions & ADU in Dania Beach, FL
A home addition in Dania Beach runs $45,000 to $130,000, and a detached ADU runs $90,000 to $220,000. Second story additions fall in the same $45,000 to $130,000 range as full home additions. The price gap between coastal spec and inland spec is real. An addition built with standard zinc-plated hardware might save a few thousand dollars up front, but you’ll pay that back in rusted connectors, failed inspections, and insurance headaches inside a decade. Here’s the line-item breakdown:
| Project Type | Typical Dania Beach Range |
|---|---|
| Home Addition | $45,000 - $130,000 |
| ADU Construction (detached) | $90,000 - $220,000 |
| Second Story Addition | $45,000 - $130,000 |
| Garage Conversion ADU | $30,000 - $80,000 |
These numbers reflect Dania Beach’s specific permitting layers and salt-air material requirements. Your exact price depends on lot elevation, FAA review if the project adds height, and the condition of existing framing. We give you a written line-item quote before work starts. Call (877) 610-1318 for a free estimate, and you’ll know exactly what you’re paying before the first nail moves.

FAQs - Home Additions & ADU in Dania Beach
In most cases, yes. Dania Beach sits directly beneath Fort Lauderdale-Hollywood International Airport’s approach surfaces, so any structure or equipment exceeding roughly 35 to 50 feet in certain corridors requires FAA Form 7460-1 Notice of Proposed Construction before the city issues a permit. Barrett & Sons files this form for you and tracks the response. Call (877) 610-1318 to find out whether your specific project triggers FAA review. Estimates are free.
The material difference is real. Salt air from the Atlantic and the Intracoastal accelerates corrosion on standard zinc-plated fasteners, so a coastal-spec ADU in Dania Beach requires hot-dipped galvanized or stainless hardware, marine-grade finishes, and sealed paver joints. That adds cost now and saves you rust streaks, failed inspections, and replacement work within a decade. Call (877) 610-1318 for an exact quote. The estimate is free.
Usually yes, because a garage conversion adds living space without adding vertical height. As long as you don’t put rooftop mechanical equipment on the structure, FAA Form 7460-1 typically isn’t required. The bigger consideration is slab elevation relative to current FEMA flood maps, and that’s something we check before any permit gets filed. Garage conversions in Dania Beach run $30,000 to $80,000. Call (877) 610-1318 for a free estimate.
Homes built before 1992 in Dania Beach predate Broward’s post-Hurricane Andrew HVHZ codes. Before an addition, they typically need hurricane straps, impact glazing, and reinforced roof-to-wall connections to meet current standards. In older 33004 neighborhoods, we often find original zinc-plated straps that salt air has eaten through, and we write a change order to replace them before inspection. Call (877) 610-1318 to schedule a structural assessment. It’s part of the free estimate.
Yes. The third-party inspector for the permit office in Dania Beach checks hardware before walls close, and we want that inspection to pass with the right connectors in place. We specify hot-dipped galvanized or stainless hardware in the original scope, so there’s no change order needed later and no surprise after the walls are closed. Call (877) 610-1318 for a free estimate, and we’ll show you the exact hardware we spec and why.
