Fast, Reliable Home Additions & ADU Across Sunrise
A typical home addition in Sunrise runs $45,000 to $130,000, and a detached ADU generally lands between $90,000 and $220,000. That’s real money, and it’s why we’d rather hand you an honest line-item number before the first wall comes down than surprise you after the framing goes up. Barrett & Sons Construction has been handling additions and conversions across Sunrise since well before the current code cycle tightened things up, and our crews know exactly what Broward County inspectors will flag when they walk a 1970s concrete block home in the 33304 zip. If you’re thinking about a room addition, a garage conversion, or a full detached ADU, call Tom Barrett’s team at (877) 610-1318 for a free estimate and a straight answer on what your house will actually require.
Why Barrett & Sons Construction Is Sunrise’s Preferred Home Additions & ADU Company
Tom Barrett put his name on the truck in 1998, and his sons run the crews. That’s not marketing language, it’s just how we work. When you call about an addition or ADU in Sunrise, you get a live person on the phone, 24/7, not a call center. You’ll talk to someone who has walked dozens of Sunrise homes near the Sawgrass Mills corridor, off Nob Hill Road, and through the older eastern tracts where the housing stock all predates Hurricane Andrew.
We carry the same written guarantee on every Sunrise job that we’ve carried for over 29 years: the 90-Day Done Right Promise. If something isn’t done right, one call brings Tom back. No forms, no case numbers, no fighting with a national office. Ask anyone on your street, or look up the license number yourself. Tom publishes his name, his address, and his license number, and he expects you to verify all of it before you sign a contract.
For our Home Additions & ADU work in Sunrise specifically, we’ve learned what this city’s housing stock throws at you. The mid-1960s through late-1980s build-out left Sunrise with thousands of single-story CBS homes that don’t meet current Florida Building Code wind-load requirements. That shapes every addition quote we write here. We’ll cover exactly how below, because it’s the single biggest reason a Sunrise addition estimate moves after the walls are opened.
Our Home Additions & ADU Services in Sunrise
Room Additions
A room addition in Sunrise typically falls between $45,000 and $130,000 depending on square footage, foundation work, and what code upgrades your existing structure triggers. Most of the room additions we build in Sunrise are ground-level expansions off the rear elevation, tied into the existing CBS wall system. The critical step is the inspection before we bid. We walk the attic, check the existing roof-to-wall connections, and look at the slab condition before we put a number in front of you. That way the allowance for hurricane strap retrofitting is already in the contract, not a surprise showing up on change order number three.

ADU Design & Permitting
Sunrise homeowners looking at accessory dwelling units deal with a specific set of Broward County requirements, and we handle the full permit package. ADU construction in Sunrise runs $90,000 to $220,000 for a new detached unit. We prepare the drawings, submit to the county, and sit with the inspector through every phase. On a 1978 single-story CBS addition in Sunrise’s 33304 zip, our crew opened the rear exterior wall to tie in a new 400-square-foot room and found the existing trusses just toe-nailed to the bond beam with no strapping. We stopped the rough-in, wrote a change order for the required retrofit before touching the roof framing, and the county inspector signed off on the new connection before we closed the walls. That’s the difference between a crew that’s done this in Sunrise and one that hasn’t.

Garage Conversion ADU
Converting an attached garage in Sunrise runs $30,000 to $80,000 and, done right, gives you a rental unit, an in-law suite, or a home office without expanding the footprint. The challenge in Sunrise is that most 1970s and 1980s garage slabs were poured thinner than current code allows for living space, and the garage-to-house wall often lacks the lateral bracing and insulation the county now requires. We check the slab thickness, the existing electrical load, and the ceiling height before we quote a conversion. If the slab needs to be built up or replaced, that goes in the written estimate, not in a phone call after demo starts.

Junior ADU & Interior Conversion
A junior ADU is usually the fastest and least expensive way to add a legal second unit inside a Sunrise home, using existing finished space rather than new framing. We look at the layout, the existing plumbing rough-ins, and the egress requirements. On older Sunrise homes, interior conversions often require bringing the affected room’s electrical up to current code, and sometimes adding a separate metered panel if the unit will be rented. We’ve done enough of these to know that a junior ADU on a 1970s CBS home in Sunrise rarely stays a “simple wall-and-door job.” Plan for electrical, plan for egress, and expect a permit.

Trusted Brands We Service in Sunrise
We only put our name on materials we can stand behind, and that shows up in every Sunrise job we finish. For paver driveways and hardscape elements tied into a new room addition or ADU patio, we use Belgard and Techo-Bloc products, which hold up to the wet-season saturation and limestone shelf conditions we have here. For sunrooms and enclosed patios, we work with Andersen and Marvin windows, and for any roofing or water management work that an addition triggers, we install GAF and CertainTeed. We stock the common sizes and profiles our Sunrise customers need, so a supply run doesn’t stall your framing schedule. If a brand matters to you, name it on the call. If we wouldn’t live with it ourselves, we won’t put it in your contract.
Common Home Additions & ADU Problems We See in Sunrise Homes
- Roof-to-wall connections with no hurricane straps. Sunrise was built out almost entirely between the mid-1960s and the late 1980s as a planned western Broward suburb, and nearly every original CBS home predates the 1994 Florida Building Code’s strap requirements. Opening any exterior wall on one of these homes and adding square footage triggers Broward County’s requirement to retrofit the connection. A bad contractor discovers this mid-project. We include a line-item allowance on every bid.
- Wet-season water table rising to within inches of grade. Sunrise sits on a flat oolitic limestone shelf at the western edge of coastal Broward, and from June through October the water table is close enough to the surface to wreck a slab if the compacted fill and drainage weren’t done right. We test and document fill compaction before we pour anything.
- Slab moisture wicking into new flooring. This is the one we see most often on recent Sunrise additions built by other crews. If nobody checked the slab moisture before the new flooring went down, the first rainy season buckles it. Our written change orders cover slab conditioning and moisture barriers before a single board gets laid.
- Closing walls before the inspector sees the retrofit. On Sunrise additions where a code-triggered retrofit is in play, some crews drywall over the connection to keep the schedule moving. Then the inspector fails it, the drywall comes back down, and the homeowner eats the tear-out cost. Our crews don’t close a wall until the inspector has signed off on what’s behind it. The permit inspector works for you, not for me, and we treat his sign-off as the milestone it is.
Pricing for Home Additions & ADU in Sunrise, FL
Here’s what we tell every Sunrise homeowner on the first call: the range is real, and the line items matter more than the total. A ground-level room addition runs $45,000 to $130,000. A new detached ADU runs $90,000 to $220,000. A garage conversion ADU runs $30,000 to $80,000. What moves the number inside those ranges is what your house already is: a 1978 CBS home in 33304 with no hurricane strapping and a thin garage slab costs more to build on than a 1990s block home that’s already had one code-compliant re-roof. Every scope, every allowance, every price change arrives as a written change order before work happens. The allowance that isn’t on paper is a surprise waiting for a date. Call (877) 610-1318 for a free estimate, and we’ll walk the house before we talk numbers.

FAQs - Home Additions & ADU in Sunrise
Yes, in most cases. If your Sunrise home was built before the 1994 Florida Building Code took effect and has never had a code-compliant re-roof, your trusses or rafters are likely toe-nailed to the CBS wall plate with no metal strapping. Adding square footage triggers Broward County’s requirement to bring the roof-to-wall connection up to current code, even if the existing roof surface stays in place. We include a line-item allowance for this on every Sunrise addition bid, and we never close a wall before the inspector confirms the new strapping. Call (877) 610-1318 for a free walk-through and we’ll tell you exactly what your house will need.
Because Sunrise sits on a flat oolitic limestone shelf where the wet-season water table can rise to within inches of grade from June through October. Any ground-up addition or attached room built on a slab needs compacted-fill prep, drainage engineering, and a moisture barrier, or the slab wicks water and the flooring fails within the first rainy season. We test fill compaction and slab moisture before we price the job, and we put those numbers in the written estimate so you’re not paying for a failed floor later. Call (877) 610-1318 for an exact quote. Estimates are free.
Yes, and we do both. A garage conversion ADU in Sunrise runs $30,000 to $80,000, and the Broward County permit triggers are part of that job, not a separate headache for you. We check the slab thickness, the existing electrical load, the egress route, and the wall between the garage and the house before we quote. If the slab needs to be built up to living-space code or the electrical panel needs a separate meter, that’s in the written estimate. We pull the permits, we sit with the inspector, and you get a signed-off unit at the end. Call (877) 610-1318 to talk through your garage.
It means we walk your attic, check your existing roof-to-wall connections, look at the slab condition, and read your current electrical panel before we put a bid in front of you. On Sunrise’s 1970s and 1980s CBS homes, we regularly find trusses toe-nailed to the bond beam with no strapping at all, and we regularly find garage slabs poured too thin for living space. We’d rather find those things before the contract is signed than write a change order after the walls are open and the draw schedule has started. That’s what inspection first means to us. Call (877) 610-1318 and we’ll walk your house the same way.
We handle it in writing, before the change touches the job. When we open a wall on a Sunrise addition and find that the existing roof-to-wall connection needs a retrofit, we stop the rough-in, write a change order with the exact scope and the exact price, and get your signature before we do the work. We don’t touch the roof framing, and we don’t move to the next draw, until you approve the change order. That’s the only way to keep a five-figure ADU from becoming a surprise at the end. Every Barrett & Sons contract carries the 90-Day Done Right Promise, and every price change is a written change order. Call (877) 610-1318 for a free estimate and we’ll show you how the draw schedule works before you sign.
