We’re Groundwork Construction Co. of South Florida, and we know Kendale Lakes. From the 1970s-era CBS homes near the golf course to the post-Andrew rebuilds along SW 107th Avenue, we’ve worked across the 33183 zip code enough to understand what separates a straightforward addition from a project that demands extra engineering. Our crew is based in Fort Lauderdale, which means we’re on-site in Kendale Lakes within a reasonable drive - not dispatching from some call center upstate. When you’re adding square footage to a home in this part of western Miami-Dade, local knowledge isn’t a bonus. It’s the difference between a permit that sails through and one that gets held up for months because someone missed the code-era discrepancy.
Why Groundwork Construction Co. of South Florida Is Kendale Lakes’s Preferred Home Additions & ADU Company
We’ve built a reputation in Kendale Lakes by treating the pre-Andrew versus post-Andrew code split as a standard project checkpoint, not an afterthought. Homeowners here tell us they appreciate that we pull the original permit history before we ever pour concrete. Raymond Estevez, who leads our company, insists on this step personally. It’s saved more than one client from a mid-project surprise that would have added weeks and thousands to their budget.
Our response time to Kendale Lakes is same-day for initial consultations, and we schedule site visits within 48 hours of your call. That matters when you’re trying to coordinate an ADU build around school schedules, tenant move-in dates, or your own relocation timeline. We don’t make you wait two weeks to learn your slab can’t support what you had in mind.
What sets us apart from contractors who just cross the county line is our familiarity with the local conditions that slow projects down. We know the Miami Limestone bedrock sits shallow here, sometimes just below the topsoil. We know the water table rises dramatically from June through October. And we know which permitting pathways at Miami-Dade County move fastest for ADU applications in the Kendale Lakes area. That local fluency translates to fewer change orders and a build that stays closer to its original timeline.
Our Home Additions & ADU Services in Kendale Lakes
ADU Design & Permitting
Every ADU project in Kendale Lakes starts with a permit history review. We pull your home’s original construction documents to determine whether it was built under pre-1992 or post-Andrew code requirements. This single step shapes your foundation design, your window specifications, and your wind-load calculations. Our design team then develops plans that satisfy Miami-Dade’s HVHZ standards while maximizing your usable square footage. We handle the full permitting package, including site plans, structural drawings, and utility connection schematics, so you’re not navigating county offices yourself.
Garage Conversion ADU
Garage conversions are one of the most cost-effective ways to add rental income or multigenerational space in Kendale Lakes, but they come with specific challenges here. Many garages in the area were built as unconditioned slabs without the rebar tie-downs or thickened edges required for habitable space. We recently converted a detached garage into an ADU on a 1970s CBS home near the Kendale Lakes golf course. The original slab had no rebar tie-downs, a giveaway of pre-Andrew construction, so our crew had to core into the Miami Limestone bedrock to install new footings and anchor bolts. Two extra days of jackhammer work. But the addition passed HVHZ inspection on the first try. That’s the kind of upfront honesty we bring to every garage conversion quote in Kendale Lakes.
New Detached ADU
For homeowners with sufficient lot depth, a new detached ADU offers the most flexibility. In Kendale Lakes, we typically see 50-foot lots that can accommodate a 400-800 square foot structure with required setbacks. The challenge here isn’t space, it’s drainage. The flat limestone substrate and high water table mean every new foundation needs a dewatering strategy during construction and positive drainage grading afterward. We plan for this from day one, not after the first rainstorm fills your excavation. We also offer prefab ADU options through our partnerships with Abodu, Dvele, Mighty Buildings, and Boxabl for clients who want a faster path to completion.
Junior ADU & Interior Conversion
Junior ADUs, created within the existing footprint of your home, are increasingly popular in Kendale Lakes’s older neighborhoods where lot coverage limits make detached structures difficult. These projects typically involve converting a portion of the main house - often a master suite wing or a section of a larger living area - into a self-contained unit with its own entrance, kitchenette, and bathroom. The advantage is minimal exterior work. The challenge is bringing the existing structure up to current code for fire separation, ventilation, and egress. In pre-Andrew homes, this often means upgrading windows to impact-rated units and reinforcing roof-to-wall connections.
ADU Site Prep & Utilities
Site preparation in Kendale Lakes is where projects live or die. The shallow bedrock we mentioned isn’t just an inconvenience for fence posts. For ADU foundations, it can mean switching from standard spread footings to drilled piers or elevated slabs. The water table, already high, can surge overnight during wet season, turning a clean excavation into a swimming pool. Our site prep includes geotechnical consultation when needed, dewatering system installation, and coordination with Miami-Dade Utility for water, sewer, and electrical service extensions. We don’t pour concrete until the ground is ready to hold it.
Room Additions & Second Story Additions
Room additions in Kendale Lakes follow the same code-era analysis as ADUs. A second-story addition introduces its own complexity: the existing first-floor walls and foundation must be verified for the additional load. In post-Andrew rebuilds, this is usually straightforward. In pre-Andrew CBS homes, we frequently find that the original footings need widening or underpinning. Sunrooms and enclosed patios, popular in Kendale Lakes for obvious reasons, must also meet HVHZ glazing requirements - no more single-pane jalousie windows in new construction.

Common Home Additions & ADU Problems We See in Kendale Lakes Homes
- Pre-Andrew slabs without rebar tie-downs. Many homeowners assume their existing garage slab or patio pad can support an ADU. In our experience across Kendale Lakes, pre-1992 slabs frequently lack the structural continuity required for habitable space. Core testing reveals the problem, but only after you’ve already paid for plans. We test early.
- Groundwater flooding excavations overnight. The water table in Kendale Lakes sits high year-round and spikes during wet season. Without a dewatering plan, your foundation dig can fill with water in hours, delaying concrete pours and risking slab heave after construction. We install sump systems and wellpoints before breaking ground.
- Permit delays from unverified code-era assumptions. Submitting plans that assume post-Andrew construction standards for a pre-1992 home triggers review rejections that cost weeks. We verify your home’s original permit classification before design begins, matching structural specifications to the actual code generation.
- Impact window requirements overlooked in budget. Every new opening in an ADU or addition in Miami-Dade’s HVHZ must use impact-rated glazing or approved shutters. Homeowners who budget for standard windows face a mid-project cost shock. We specify Andersen, Pella, Marvin, or impact-rated PGT and CGI lines from the first estimate.
Pricing for Home Additions & ADU in Kendale Lakes, FL
A typical home addition in Kendale Lakes runs $45,000-$130,000. ADU construction ranges from $90,000-$220,000 depending on size, foundation complexity, and finish level. Garage conversions, which reuse existing structure, typically fall between $30,000-$80,000. What moves you within these ranges? Bedrock depth affects excavation cost. Pre-Andrew slabs requiring replacement add $8,000-$15,000. Impact window upgrades versus standard specification can swing material costs by 30%. And dewatering requirements during wet-season construction add equipment rental that dry-season builds avoid.

FAQs - Home Additions & ADU in Kendale Lakes
You’ll need a geotechnical review of your existing slab and a permit history pull to confirm your home’s code era. Pre-1992 slabs in Kendale Lakes frequently lack rebar tie-downs and thickened edges required for habitable structures, meaning partial or full slab replacement before the ADU build begins. Budget an additional $8,000-$15,000 for this work. Call (844) 665-0162 and we’ll inspect your specific site.
The water table in Kendale Lakes sits exceptionally high due to its position on the eastern Everglades edge, and the flat Miami Limestone substrate prevents natural drainage. Without active dewatering - wellpoints, sump pumps, or both - excavations refill overnight during wet season. This isn’t a contractor error. It’s a local condition that must be engineered around from day one. We include dewatering in our site prep scope for every Kendale Lakes ADU.
Yes. Miami-Dade County operates under high-velocity hurricane zone (HVHZ) requirements, and all new construction including ADUs must use impact-rated glazing or approved protective coverings. Standard windows will not pass inspection. We specify from Andersen, Pella, Marvin, Milgard, Jeld-Wen, Simonton, PGT, and CGI lines depending on your budget and architectural preference.
Yes, but expect additional structural work. Pre-1992 garage slabs in Kendale Lakes were typically poured as unconditioned, non-habitable surfaces without the depth, rebar, or anchor bolts required for living space. We core-test before quoting. If your slab needs replacement or augmentation, we factor that into the initial estimate - not as a change order later. Garage conversions in Kendale Lakes typically run $30,000-$80,000 depending on these variables.
A second-story addition requires Miami-Dade County building permits, structural engineering stamps, and often a zoning verification for height and setback compliance. If your home is pre-Andrew, you’ll also need a structural capacity analysis to confirm the existing foundation and first-floor walls can support the additional load. We handle the full permitting package as part of our standard project management. Call (844) 665-0162 to discuss your specific property.
