A home addition in Sunrise typically runs $45,000-$130,000, while a full detached ADU runs $90,000-$220,000.

Call (754) 714-6540 to schedule your free estimate with a written price before any work starts.
We’ve been working in Sunrise since Rowan Construction Group was founded in 2007. Our crews know the CBS ranch homes off Oakland Park Boulevard, the subdivisions near Sawgrass Mills, and the properties lining the C-11 Canal. Dispatch and scheduling run through our Miami office, but our teams live and work in Broward County, which means we’re on-site in Sunrise without the delays you get from contractors driving down from Palm Beach or across from Miami-Dade.
What makes Sunrise different from other Broward cities is the age of its housing stock and what’s underneath it. Nearly every single-family home here was built between the late 1960s and early 1990s, before Hurricane Andrew triggered Florida’s current wind-mitigation code. That matters because the moment you pull a permit to open a wall for a room addition or ADU, you’re not just adding space - you’re bringing the existing structure into compliance with current Florida Building Code standards for roof-to-wall connections, secondary water resistance, and impact-rated openings. We price this into our quotes from the start, not as a surprise halfway through demo.
Why Rowan Construction Group Pompano Beach Is Sunrise’s Preferred Home Additions & ADU Company
We’ve delivered more than 4,000 projects since 2007, every one with a written price before work started and a documented photo record when the crew left. Sunrise homeowners find us the same way they research appliances - they read the three-star reviews, they compare the numbers, and they call when they see we’ve posted actual dollar ranges on the page.
Our response time to Sunrise is same-day or next-day for estimates, because our crews are already in western Broward. We don’t subcontract permitting to someone who doesn’t know Broward County’s specific requirements; our Home Additions & ADU team pulls permits directly and schedules inspections with the same Broward County building department inspectors we’ve worked with for years.
Local knowledge matters here. We know that a footer pour in western Sunrise near the Water Conservation Areas can hit standing groundwater at 18 inches, while the same spec in eastern Sunrise might be dry. We know that homes off NW 44th Street and in the Welleby subdivision share the same 1980s CBS construction, the same aluminum single-pane windows, and the same flat roof sections prone to ponding. This isn’t generic experience - it’s the specific history of the houses we work on.
Our Home Additions & ADU Services in Sunrise
ADU Design & Permitting
ADU design and permitting in Sunrise starts with a site survey and a Broward County zoning check, not a sketch. Sunrise allows detached ADUs on single-family lots under specific setback and coverage rules, and the permitting process triggers Florida Building Code compliance for the entire property, not just the new unit. We handle the architectural plans, the structural engineering for wind loads, and the permit submission to Broward County. A typical detached ADU in Sunrise runs $90,000-$220,000, with permitting adding 4-8 weeks to the front of the schedule.
Garage Conversion ADU
Garage conversions in Sunrise are popular in neighborhoods like Welleby and Sunrise Golf Village, where the original two-car garages are underutilized and the lot coverage already maxes out detached options. The challenge is that most Sunrise garages share a roof structure with the main house and sit on slabs poured without the depth or reinforcement needed for living space. We inspect the slab, the roof tie-ins, and the existing HVAC capacity before quoting. A garage conversion ADU in Sunrise typically runs $30,000-$80,000, with the wide range reflecting whether the slab needs replacement and whether the existing electrical panel can handle the additional load.
New Detached ADU
New detached ADUs in Sunrise work best on larger lots in areas like Sawgrass Estates or the neighborhoods west of Flamingo Road, where setbacks allow a separate structure without coverage violations. The shallow water table in western Sunrise - often 18 to 36 inches to groundwater - means nearly every detached ADU foundation requires active dewatering during excavation and footer pour. We include this as a written line item in our quotes, not as a change order surprise. The foundation work alone can add $8,000-$15,000 compared to similar construction in eastern Broward with deeper, drier soils.
Junior ADU & Interior Conversion
Junior ADUs - a self-contained unit within the existing footprint - work in Sunrise’s larger ranch homes, particularly the 1,800-2,400 square foot CBS plans common in 1970s and 1980s subdivisions. The constraint is usually the existing electrical service (100-amp panels were standard) and the lack of separate HVAC zoning. We price the electrical upgrade, the mini-split installation, and the fire-separation requirements as separate line items so you see where the money goes. Junior ADUs in Sunrise typically fall in the lower half of the $45,000-$130,000 home addition range.

AfterTrusted Brands We Service in Sunrise
Rowan Construction Group sources across fifty-plus vetted brands, and we stock the ones that matter for Sunrise’s climate and code requirements. For roofing tie-ins on additions, we specify Owens Corning or Atlas shingles with secondary water resistance barriers that satisfy current Florida Building Code wind-mitigation standards. For windows and exterior doors, we use impact-rated products that meet Miami-Dade and Broward requirements - not just the sticker, but the full NFRC rating documentation that Broward inspectors ask for. We don’t inflate quotes with premium brands you didn’t request, and we don’t substitute cheaper materials without a signed change order. The brand names in your written quote are the brands on your job site.
Common Home Additions & ADU Problems We See in Sunrise Homes
- Pre-1992 wind-code gaps. Open a wall on a 1980s CBS home in Sunrise and you’ll often find no hurricane strapping at the top plate, no secondary water resistance under the roof deck, and single-pane aluminum windows. The permit triggers upgrades to all three, which we identify during pre-demo inspection and write into the contract as allowances.
- Shallow groundwater on western lots. Excavation for ADU footers in neighborhoods near the C-11 Canal routinely hits standing water within two feet of grade. We specify submersible dewatering pumps and engineered fill as standard line items, not surprises.
- Undersized electrical panels. Most Sunrise homes from the 1970s-1990s have 100-amp service panels that can’t handle an addition or ADU load. We verify panel capacity during our first site visit and price the upgrade before permit submission.
- Flat roof ponding and concealed rot. The low-slope roof sections common on Sunrise ranch homes often conceal years of water intrusion. We cut inspection holes before quoting and photograph the sheathing condition so the homeowner sees what we see.

Whether the existing electrical, HVAC, and plumbing systems can handle the additional load or need replacement. And the finish level - a basic ADU with vinyl flooring and stock cabinets sits at the low end; custom tile, quartz counters, and upgraded fixtures move it up.

FAQs - Home Additions & ADU in Sunrise
Because nearly every Sunrise home was built before Florida’s 1992 wind-code overhaul, pulling a permit triggers mandatory upgrades to roof-to-wall connections, secondary water resistance, and impact-rated openings that weren’t visible when you first called about a bump-out. We avoid this surprise by cutting inspection holes and writing allowances into the contract before demo begins. Call (754) 714-6540 for an exact quote - estimates are free.
Yes. Western Sunrise sits adjacent to the Everglades drainage system with groundwater often 18-36 inches below grade, so footer excavations routinely require active dewatering with submersible pumps. We include this as a written line item in our quotes; out-of-area contractors often miss it and hit you with a change order later. Call (754) 714-6540 for an exact quote - estimates are free.
Broward County requires architectural plans, structural engineering for wind loads, and proof of Florida Building Code compliance for the existing structure once walls are opened. We handle the full submission, schedule inspections, and don’t close walls until the inspector signs off - re-opening finished work adds weeks. Call (754) 714-6540 for an exact quote - estimates are free.
Usually yes, but the garage slab, roof tie-ins, and electrical panel must meet current code for the converted space, and the permit may trigger wind-mitigation upgrades to the main house if they share a roof structure. We inspect all three before quoting so you know the full scope upfront. Call (754) 714-6540 for an exact quote - estimates are free.
We cut inspection holes before demo, photograph what we find, and write allowances into the contract for likely conditions like hidden rot, code upgrades, or groundwater.
