Why Groundwork Construction Co. of Miami Is Oakland Park’s Preferred Home Additions & ADU Company
We’ve worked across Broward County long enough to know that Oakland Park isn’t a generic Miami suburb. The city is dense with 1950s-1970s concrete block homes, many with flat roofs and carport conversions done under older codes. That history matters when you’re pulling permits for a garage conversion ADU or a second-story addition. Our Home Additions & ADU team has navigated these exact Broward County inspections, and we know what triggers a full wind-mitigation upgrade versus what passes as-is.
Homeowners in Oakland Park choose us because we’re a single-source contractor. You don’t juggle a separate roofer, window installer, and structural crew. From driveway to roofline, one team manages every phase. Raymond Estevez, who leads Groundwork, has built our reputation on exactly this accountability.
Our response time to Oakland Park is typically same-day for initial consultations, and we keep materials from our 50+ brand partnerships stocked for Miami availability. That means less waiting on impact-rated windows or roof-deck fasteners when your permit clock is running.
Our Home Additions & ADU Services in Oakland Park
ADU Design & Permitting
ADU design and permitting in Oakland Park starts with understanding what Broward County will require before a shovel hits dirt. In this city, that almost always means a wind-mitigation assessment of the existing structure. We’ve designed detached ADUs off Prospect Road and junior ADUs near the Oakland Park Boulevard corridor, and every project begins with a realistic permit timeline that accounts for code-upgrade contingencies. You choose the brand, we handle the build, and we flag the compliance issues early so your budget doesn’t balloon mid-project.
Garage Conversion ADU
Garage conversions are one of the most cost-effective ways to add living space in Oakland Park, typically running $30,000-$80,000. But they’re also where we see the most permit surprises. On a garage conversion ADU off NE 38th Court, our crew found the original 1960s jalousie windows framing the future living area wouldn’t meet FBC wind-load ratings. We replaced them with impact-rated units and reinforced the existing roof-to-wall connections before Broward County would schedule the final inspection, transforming an unpermitted carport space into a code-compliant, storm-ready unit. That field experience shapes how we quote every Oakland Park garage conversion now.
New Detached ADU
Detached ADUs in Oakland Park give you rental income or multigenerational space without altering your main home’s footprint. We build these stick-built or with prefab partners like Mighty Buildings, Boxabl, or Plant Prefab, depending on your timeline and site constraints. Site prep matters here: Oakland Park’s low-lying lots hold water after summer storms, so we address drainage and slab waterproofing before any walls go up. Built to spec, not to convenience, means your ADU starts with a foundation that won’t wick moisture into finished living space.
Junior ADU & Interior Conversion
Junior ADUs, or JADUs, convert existing interior space within your home’s footprint, often with a separate entrance. In Oakland Park’s smaller CBS homes near the intersection of Andrews Avenue and Oakland Park Boulevard, this can be the only viable expansion option when setback rules prevent exterior growth. These projects still trigger wind-mitigation reviews if they involve structural changes, and we handle the permitting path that distinguishes a JADU from a full ADU under Broward County’s local amendments to Florida’s statewide ADU law.

Trusted Brands We Service in Oakland Park
Groundwork works with 50+ recognized industry brands, and that breadth matters for Oakland Park’s specific conditions. For ADU and home addition projects, we specify impact-rated windows from Andersen, Pella, or PGT when FBC wind-load compliance is required. Roofing materials draw from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so your addition’s roof matches or exceeds the main structure’s rating. For prefab ADU structures, we partner with Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed, giving you modern, fast-track options alongside traditional construction. We don’t lock you into a single vendor. You choose the brand, we handle the build.
Common Home Additions & ADU Problems We See in Oakland Park Homes
- Skipping the roof-deck re-nailing requirement: Old 6/12 nail spacing on flat roofs fails inspection and leaves the addition vulnerable to blow-off. We see this constantly on 1960s CBS homes where homeowners assumed a membrane replacement would suffice.
- Reusing outdated single-pane or jalousie windows in the new addition: These don’t meet impact ratings and fail during storms, causing pressure and water intrusion. Broward County won’t pass final inspection without rated replacements.
- Starting interior work before addressing moisture wicking through the slab: Oakland Park’s high humidity and summer standing water mean concrete block foundations and slabs absorb moisture constantly. Stucco delamination and mold follow if the slab isn’t properly waterproofed first.
- Undersized roof-to-wall connections on second-story additions: The original 1950s-1970s hardware wasn’t designed for current wind loads, and adding mass above without upgrading these connections creates a structural liability that inspectors flag immediately.
Pricing for Home Additions & ADU in Oakland Park, FL
Honest numbers for Oakland Park’s market, calibrated for the wind-mitigation realities of older CBS homes:
| Service | Price Range in Oakland Park |
|---|---|
| Home Addition | $45,000-$130,000 |
| ADU Construction | $90,000-$220,000 |
| Garage Conversion | $30,000-$80,000 |
These ranges assume typical Oakland Park conditions: flat or low-pitch roofing, concrete block construction, and the wind-mitigation upgrades Broward County requires before permit close. A garage conversion at the lower end might need only window replacements and connection reinforcement. A detached ADU on a challenging lot near the Middle River could run higher due to site prep and utility extension. We don’t quote blind. Every estimate starts with a site visit to your Oakland Park property, and estimates are free. Call (844) 665-0162 to schedule.

FAQs - Home Additions & ADU in Oakland Park
Broward County requires current Florida Building Code roof-deck nailing spacing before any addition permit closes, and 1960s homes typically have 6/12 spacing that fails modern wind-load standards. This isn’t optional, and it isn’t something you can negotiate around. The re-nail protects the entire structure during hurricane-force winds, not just the new addition. Call (844) 665-0162 and we’ll assess your existing deck during our free estimate.
Yes, single-pane jalousie windows do not meet FBC impact ratings and will fail inspection for any permitted living space conversion. We replace them with rated units from Andersen, PGT, or similar brands as part of our standard garage conversion scope for Oakland Park. The replacement cost is factored into our $30,000-$80,000 garage conversion range. Call for a specific quote on your property.
Usually, but only after we verify moisture barriers and elevation relative to grade. Oakland Park’s summer standing water wicks through unprotected slabs, causing mold and flooring failure. We test for moisture intrusion and specify waterproofing if needed before any finished flooring goes down. The slab itself is often structurally sound, it’s the envelope around it that needs attention.
A JADU uses existing interior space within your home’s footprint with a separate entrance, while a full ADU is a separate dwelling unit either attached or detached. Broward County’s local amendments cap JADU size differently and may waive certain utility-separation requirements, but both still trigger wind-mitigation review if structural changes are involved. We navigate the specific permitting path based on your property’s zoning and your goals.
Wind-mitigation upgrades for a second-story addition on a 1950s-1970s Oakland Park home typically add $8,000-$18,000 to the base project cost, covering roof-deck re-nailing, upgraded roof-to-wall connections, and impact-rated window replacements. This is in addition to the $45,000-$130,000 home addition range. We identify these costs during our initial site visit so you’re not surprised at inspection.
