Why Groundwork Construction Co. of Miami Is Hallandale’s Preferred Home Additions & ADU Company
We’ve worked Hallandale long enough to know the local building stock inside out. The city isn’t like the newer developments sprouting up in western Broward. Here, you’re dealing with legacy concrete block construction, post-tensioned slabs from the 1970s, and a salt-laden marine environment that eats standard materials alive. That matters when you’re cutting into a slab for plumbing or fastening an addition frame that’ll face decades of Intracoastal breeze.
Our Home Additions & ADU team has completed projects throughout the 33009 zip, including garage conversions in the single-family pockets off Hallandale Beach Boulevard and interior reconfigurations in older mid-rise buildings. Homeowners in Hallandale choose us because we don’t hand off projects to subcontractors you’ve never met. One contractor, every phase. You choose the brand, we handle the build.
Raymond Estevez, who leads Groundwork, personally reviews every ADU and addition project plan before permitting. That direct accountability matters when you’re navigating Hallandale’s specific code requirements for coastal construction.
Our Home Additions & ADU Services in Hallandale
ADU Design & Permitting
Hallandale’s permitting process for ADUs involves both city and, in many condo associations, HOA architectural review. We handle the full submission package, including structural drawings that account for Hallandale’s wind-load requirements and, where applicable, GPR scan documentation for post-tensioned slabs. Our design team specs materials from brands like James Hardie for siding and KraftMaid for cabinetry, so your ADU matches your main home’s quality.
Garage Conversion ADU
This is our most requested ADU type in Hallandale’s single-family neighborhoods. Most CBS ranches here have attached garages on slabs poured in the 1960s or 1970s, often with post-tensioned reinforcement. We recently converted a garage into a junior ADU for a homeowner on NE 10th Terrace, a classic 1960s CBS ranch where the original slab had minor cracking. Our techs used GPR scanning to locate the old PT tendons before coring for new plumbing, then installed a Kohler walk-in shower and Moen fixtures, finishing with a Cambria countertop in the kitchenette. The job came in closer to $30,000 because existing plumbing runs were reuseable, but we sealed the concrete with a marine-grade waterproofing to ward off salt air.
New Detached ADU
For Hallandale homeowners with sufficient lot depth, we offer both traditional stick-built construction and prefab options through our partnerships with Abodu, Dvele, Mighty Buildings, and Boxabl. Prefab units can cut site time significantly, which matters in Hallandale’s climate where afternoon thunderstorms can delay exterior work. Every detached ADU we build uses corrosion-resistant fasteners and pressure-treated or composite materials rated for Miami’s salt exposure.
Junior ADU & Interior Conversion
In Hallandale’s condo towers and older multi-family buildings, a full detached unit isn’t always possible. Junior ADUs, created by reconfiguring interior space and adding kitchenette facilities, are often the path forward. We specialize in these conversions within Hallandale’s 1960s-1980s concrete frame buildings, coordinating with association engineers to ensure our work doesn’t compromise structural integrity or violate SB 4-D compliance timelines.
ADU Site Prep & Utilities
Hallandale’s flat, low-lying terrain means drainage planning is critical. We handle full site prep including soil assessment, utility trenching, and connection to existing sewer and electrical. In areas near the Intracoastal, we often specify raised foundation systems or enhanced waterproofing to protect against seasonal high water and salt intrusion.

Common Home Additions & ADU Problems We See in Hallandale Homes
- Hidden post-tensioned tendon damage. Skipping GPR scanning before cutting or coring into 1970s PT slabs risks tendon rupture and structural failure. Hallandale’s first-generation PT systems are particularly vulnerable, and we’ve seen original tendon anchors corroded behind stucco facades with zero visible cracking.
- Standard materials failing in salt air. Using regular lumber and fasteners on additions that will face 30 years of salt-laden air near the Intracoastal leads to premature rust and rot. We specify hot-dipped galvanized or stainless hardware and treated or composite framing.
- Condo association infrastructure conflicts. Failing to integrate new ADU plumbing and electrical with aging condo association systems in Hallandale’s 1960s-1980s towers causes permit delays or code violations. We coordinate with association engineers before submitting city permits.
- Inadequate waterproofing on legacy slabs. Hallandale’s original CBS ranch slabs often lack modern vapor barriers. Without marine-grade sealing, new ADU flooring can fail from below due to moisture wicking and salt deposit buildup.

FAQs - Home Additions & ADU in Hallandale
Yes, if your home was built between the 1960s and 1980s and has a post-tensioned slab, GPR scanning is essential before any cutting or coring. Hallandale’s first-generation PT systems frequently have corroded tendon anchors hidden behind stucco with no surface cracking. The scan costs $400-$800 but prevents structural failure that could cost tens of thousands to repair. Call (844) 665-0162 to schedule a pre-construction assessment.
Hallandale’s marine microclimate and aging building stock require material and procedural upgrades that inland markets don’t need. Marine-grade fasteners, enhanced waterproofing, GPR scanning, and coordination with association engineers in condo buildings all add cost. A garage conversion here typically runs $30,000-$80,000 versus $25,000-$60,000 in non-coastal markets. The investment protects against salt-induced failure over decades. Call (844) 665-0162 for a detailed breakdown.
Yes, CBS ranch properties in Hallandale’s single-family neighborhoods are excellent candidates for garage conversions or detached ADUs, provided setbacks and lot coverage rules are met. The key is addressing the original slab’s condition and any post-tensioned reinforcement before construction begins. We handle the structural assessment and permitting as part of our standard process. Call (844) 665-0162 to evaluate your specific property.
Hallandale Beach requires coastal construction zone compliance, wind-load engineering for additions, and in many condo associations, architectural review board approval before city submission. Florida’s SB 4-D also means some buildings over 30 years old must complete milestone inspections before significant alterations are permitted. We navigate these layers simultaneously to avoid delays. Call (844) 665-0162 and we’ll review your building’s compliance status.
Specify impact-rated windows from lines like PGT or CGI, use James Hardie siding or equivalent fiber-cement cladding, install marine-grade waterproofing on all concrete surfaces, and select stainless or hot-dipped galvanized fasteners throughout. We also recommend raised electrical outlets and sealed exterior penetrations to prevent wind-driven water intrusion. These upgrades add 10-15% to base construction cost but eliminate the premature failure we see in standard-spec builds. Call (844) 665-0162 to discuss protection levels for your project.
