Why Groundwork Construction Co. of Miami Is Davie’s Preferred Home Additions & ADU Company
We’ve worked in Davie long enough to know that a standard Broward County permit pull won’t cut it here. Our Home Additions & ADU team navigates both the Town of Davie’s Planning and Zoning Division and Broward County Building Division on every equestrian-zone project, which means our clients don’t get blindsided by a rejected application three weeks in.
Davie’s housing stock is different from what you’ll find in Miami or Hollywood. The 1960s-1980s CBS ranch homes on larger lots throughout 33314 and surrounding ZIPs weren’t built to modern wind-mitigation standards, and many garages lack insulation entirely. We’ve converted enough of these spaces to know where the code gaps are before we start demolition.
Our response time to Davie is same-day for consultations, and we carry the full scope of work in-house - no handoffs to mystery subcontractors. One contractor, every phase. You choose the brand, we handle the build.
Our Home Additions & ADU Services in Davie
Garage Conversion ADU
This is our most requested ADU type in Davie, and for good reason. Those single-car and two-car garages in the older CBS ranches near Griffin Road and Orange Drive are spacious enough for a studio or one-bedroom unit, but they almost always need serious upgrading. We recently completed a garage conversion ADU in a 1970s CBS ranch near Davie’s western equestrian zone, just off Flamingo Road. The homeowner’s original single-car garage had a manual chain-drive opener and zero insulation in the walls, so we upgraded to a Wi-Fi-enabled smart opener with battery backup and added closed-cell foam to the existing block walls to meet the 1994 Florida Building Code’s wind-mitigation expectations. The result: a cool, quiet studio that the owner now rents out, with the town’s stamp of approval.
ADU Design & Permitting
Davie’s permit process is where projects live or die. In the equestrian overlay districts - and there are more of them here than anywhere else in Miami - converting a barn or feed room into a legal ADU requires a dual-permit sequence: the Town’s Planning and Zoning Division must approve the equestrian use compatibility, then Broward County Building Division issues the structural permit. This step doesn’t exist in Miami or Pembroke Pines. Out-of-town builders skip the separate equestrian use compatibility review and try to pull a standard accessory structure permit, only to get stuck when Broward County Building Division rejects the application. We handle both agencies from day one, so your project doesn’t stall.
New Detached ADU
For homeowners on Davie’s larger equestrian-zoned parcels, a new detached ADU opens real possibilities - rental income, multigenerational living, or a dedicated workspace. We build these traditionally or through our prefab partnerships with Mighty Buildings, Boxabl, and Plant Prefab for faster timelines. The catch in Davie is the site itself. Davie sits on the western edge of Broward County’s coastal ridge, transitioning toward the Everglades drainage basin, which produces a notably higher and less predictable water table than eastern Broward cities. Slab foundations and underground drainage work routinely encounter groundwater at shallow depths, complicating footings, French drains, and any below-grade construction. We dewater properly and specify vapor barriers as standard, not optional.
Junior ADU & Interior Conversion
Not every Davie homeowner has a garage or outbuilding to convert. Junior ADUs - self-contained units carved from existing interior space - work well in the larger ranch homes near Pine Island Ridge and Cooper City borders where square footage allows. These projects still trigger permitting scrutiny if they add kitchen facilities or separate entrances, and we make sure the design integrates with your home’s existing structural and utility systems rather than fighting them.

Common Home Additions & ADU Problems We See in Davie Homes
- Dual-permitting failures on equestrian properties. Contractors unfamiliar with Davie submit to Broward County Building Division without first clearing equestrian use compatibility with the Town’s Planning and Zoning Division. The application gets rejected, the timeline blows up, and the homeowner pays for the delay.
- Uninsulated garage walls that fail modern energy code. Older CBS garages in Davie often have no wall insulation and dated openers without battery backup, so a garage conversion fails modern energy and safety codes if those aren’t upgraded during the ADU work. We address this in the initial scope, not as a change order.
- Groundwater intrusion in slab-on-grade ADU foundations. Groundwater from Davie’s high, unpredictable water table seeps into slab-on-grade ADU foundations if the soil isn’t properly dewatered and the slab is poured without a vapor barrier, leading to moisture issues and warped subfloors. We spec both as standard practice.
- Flood zone elevation requirements. Several Davie parcels fall within FEMA Special Flood Hazard Areas, meaning new construction and substantial improvements must meet elevated finished-floor requirements under both federal and Broward County floodplain ordinances. We verify flood zone status before design begins.
Pricing for Home Additions & ADU in Davie, FL
Here’s what Davie homeowners can expect for typical project types:
| Project Type | Price Range in Davie |
|---|---|
| Garage Conversion (ADU) | $30,000-$80,000 |
| ADU Construction | $90,000-$220,000 |
| Home Addition | $45,000-$130,000 |
| Slider or Patio Door Upgrade | $1,000-$1,000 |
What moves the needle within these ranges? Site conditions - especially groundwater management and any needed soil remediation. Finish level - a basic rental studio costs less than a fully appointed in-law suite with custom cabinetry from KraftMaid or Wellborn and quartz countertops from Cambria, Silestone, or Caesarstone. Permit complexity - equestrian-zone dual permitting adds administrative time but avoids costlier mid-project stops. And integration with existing systems: tying into your home’s electrical panel, HVAC, and plumbing versus running independent utilities. We price upfront after a site visit, not from satellite photos. Call (844) 665-0162 for your free estimate.

FAQs - Home Additions & ADU in Davie
Davie’s active equestrian overlay zoning district requires a dual-permit sequence for any ADU on affected parcels: the Town’s Planning and Zoning Division must approve equestrian use compatibility before Broward County Building Division will issue the structural permit. Miami has no comparable agricultural zoning layer, so its permitting is single-agency. Call (844) 665-0162 and we’ll verify your parcel’s zoning in the first conversation.
Yes, but only if the structure meets the equestrian use compatibility review and subsequent building code compliance for residential occupancy. Many Davie barns and agricultural outbuildings were built without permits or to non-residential standards, so the conversion often requires structural upgrading, insulation, utility installation, and finished-floor elevation if the parcel sits in a FEMA flood zone. We assess existing conditions before committing to a build path.
Davie’s position on the western edge of Broward’s coastal ridge means groundwater sits closer to the surface than in eastern cities, which complicates excavation, footing depth, and below-grade drainage. Without proper dewatering during construction and a full vapor barrier under the slab, moisture wicks upward into finished flooring and triggers mold or warping. We engineer for these conditions as standard, not as an upgrade.
If your Davie parcel falls within a FEMA Special Flood Hazard Area, yes - new construction and substantial improvements must meet elevated finished-floor requirements under both federal and Broward County floodplain ordinances. We pull flood zone maps during preliminary design and adjust foundation height accordingly, which affects both cost and the structure’s relationship to your main house. Call (844) 665-0162 for a site-specific assessment.
Yes - it’s practically required. Davie’s 1994 Florida Building Code and subsequent amendments mandate battery backup on garage door openers for safety during power outages, and most pre-1990s openers lack this feature entirely. A Wi-Fi-enabled smart opener also lets you monitor and control the door remotely, which matters when the space becomes a rental with its own occupants. We bundle this upgrade into the conversion scope rather than treating it as an afterthought.
