Why Groundwork Construction Co. of South Florida Is Sunrise’s Preferred Home Additions & ADU Company
We’ve worked in Sunrise long enough to know that building here isn’t like building in newer Broward cities. The 1970s and 1980s CBS construction that dominates this city - concrete block, stucco, flat roofs, pre-Andrew code - creates a specific set of challenges that out-of-town contractors underestimate. Our Home Additions & ADU team has coordinated directly with Broward County Building Code Services on multiple recertification-flagged projects, so we know the inspection sequence before we pull the first permit.
Sunrise homeowners call us because we handle the full scope: structural remediation, engineered repairs, and the actual addition or ADU build. No handoffs. We’re a single-source contractor, which matters when your project starts with rebar replacement and ends with a finished living space.
We serve all of Sunrise, including the 33304 zip code and neighborhoods from Welleby to Sunrise Golf Village. Our response time to Sunrise inquiries is same-day during business hours, and we schedule site visits within 48 hours for active projects.
Our Home Additions & ADU Services in Sunrise
ADU Design & Permitting
ADU permitting in Sunrise runs through Broward County’s unified building department, but the real complexity is front-loaded. Most Sunrise properties we assess need preliminary structural evaluation before the ADU design can even be finalized, especially if the primary structure is approaching or past the 40-year recertification threshold. We coordinate the engineering, produce permit-ready drawings, and sequence the application so you’re not paying carrying costs while paperwork stalls. Our design process accounts for Sunrise’s specific zoning - lot coverage rules, setback requirements from major corridors like Oakland Park Boulevard, and HOA restrictions in planned communities like Welleby.
Garage Conversion ADU
Garage conversions are the most common ADU type we build in Sunrise, particularly in townhome clusters and older single-family neighborhoods where detached space is limited. A typical garage conversion ADU in Sunrise runs $30,000-$80,000, though we’ve seen projects climb higher when recertification issues surface mid-demo. On a Sunset Strip townhome, our crew converted an attached garage into a junior ADU, but the recertification inspection flagged corroded rebar in the slab and a spalled concrete column, so we first coordinated with the engineer and the HOA to restore structural integrity before adding new plumbing and electrical rough-ins. The project also upgraded the old electrical service to a modern, code-compliant panel as part of the conversion. This is standard practice for us - we don’t frame walls over compromised concrete.
New Detached ADU
Detached ADUs in Sunrise face two site-specific hurdles: the high water table in western Broward, which complicates slab foundations and requires engineered drainage, and the prevalence of zero-lot-line or near-zero-lot-line plats in 1970s subdivisions that limit buildable footprint. We address both during pre-construction. For the foundation, we specify elevated slab or stem-wall designs with perimeter drainage that handles the wet-season saturation. For space constraints, we partner with prefab innovators including Abodu, Dvele, Mighty Buildings, and Boxabl to deliver compact, high-quality units that minimize on-site construction time and neighborhood disruption. Traditional stick-built remains an option where lot size allows.
Junior ADU & Interior Conversion
Junior ADUs - converted interior space with a separate entrance, no additional square footage added - work well in Sunrise’s condo and townhome market where exterior expansion is physically or legally impossible. We’ve converted ground-floor units in garden-style complexes near NW 44th Street into independent living spaces for aging parents or rental income. The constraint is always the existing building systems: 1970s electrical panels and galvanized plumbing rarely handle the additional load without full replacement. We assess this upfront so the budget reflects reality, not just drywall and fixtures.
ADU Site Prep & Utilities
Site prep in Sunrise is where projects live or die. The wet season, June through October, brings intense afternoon thunderstorms that can halt exterior work for days and flood unprepared excavation. We schedule critical below-grade work - footers, utility trenches, drainage - for the drier months when possible, and we specify moisture barriers and sump systems as standard, not upgrades. For utility connections, Sunrise’s older infrastructure often requires service upgrades, particularly for electrical. We coordinate with Florida Power & Light and the city’s utility department so you’re not waiting months for a meter installation while construction sits idle.

Trusted Brands We Service in Sunrise
We don’t lock Sunrise homeowners into proprietary products. You choose the brand, we handle the build. For ADU kitchens, that means KraftMaid or Wellborn cabinetry - both available in multiple tiers so the budget drives the selection, not our purchasing convenience. For countertops, we offer Cambria, Silestone, and Caesarstone engineered quartz, each with distinct color palettes and warranty terms. Exterior cladding on additions draws from James Hardie fiber-cement siding, specified frequently in Sunrise for its impact resistance and compliance with post-Andrew wind-load requirements. We maintain supplier relationships across South Florida, so lead times for these materials stay predictable even when demand spikes during the dry-season building rush.
Common Home Additions & ADU Problems We See in Sunrise Homes
- Recertification surprises derail timelines. Owners order ADU or addition materials and framing before resolving recertification-flagged structural issues like corroded rebar, forcing full teardown of new work to access the concrete. We sequence structural remediation first, always.
- Wet-season slab failures. Contractors pour slabs or dig footers during the wet season without accounting for Sunrise’s high water table, leading to hydrostatic pressure cracks and moisture intrusion that compromise the new ADU. Our site prep includes engineered drainage and seasonal scheduling.
- Overloaded existing systems. Adding an ADU or addition without first verifying the existing electrical and plumbing can handle the load - especially in older 1970s CBS buildings - prompts a full rewire or re-pipe that blows the budget. Our pre-construction assessment catches this.
- HOA and corridor restrictions. Properties along major roads like Oakland Park Boulevard or in master-planned communities often face design review boards with aesthetic requirements we must incorporate into the initial drawings, not retrofit later.

FAQs - Home Additions & ADU in Sunrise
If your building is flagged for recertification, all new construction permits are held until structural deficiencies are resolved. This means your ADU project may need to start with engineered repairs - rebar replacement, column restoration, or balcony slab remediation - before framing begins. We coordinate this sequence so you’re not paying for work that gets torn out later. Call (844) 665-0162 and we’ll check your building’s recertification status during the initial site visit.
A garage conversion ADU in Sunrise typically costs $30,000-$80,000, with most projects landing in the $45,000-$65,000 range for standard finishes and no structural surprises. If recertification issues appear once demolition exposes the slab, repair costs add $8,000-$25,000. We price the structural assessment separately so you know the full picture before committing. Call (844) 665-0162 for an exact quote - estimates are free.
Yes, provided your lot meets current setback and coverage requirements, but the age of the primary structure matters for utility capacity and foundation design. Many 1970s Sunrise homes need electrical service upgrades and engineered drainage for the new slab due to the high water table. We assess both during pre-construction planning so the permit application is complete the first time. Call (844) 665-0162 to review your specific lot.
Corroded rebar and spalled concrete in balcony slabs or garage floors can’t be patched cosmetically - the repair requires exposing all damaged steel, treating or replacing it, and pouring new concrete to engineered specifications. Partial repairs rarely satisfy Broward County’s Building Code Services, and any ADU built over a compromised slab risks future failure. We do it once, to code, so your new space lasts. Call (844) 665-0162 if your building has received a recertification notice.
The dry season, November through April, is optimal for foundation and exterior work in Sunrise. The wet season’s afternoon thunderstorms compress schedules and complicate below-grade drainage installation. We can build year-round, but starting in fall typically saves 2-4 weeks on overall timeline by avoiding weather delays. Call (844) 665-0162 to discuss your target move-in date and we’ll back-schedule from there.
