Why Groundwork Construction Co. of South Florida Is Gladeview’s Preferred Home Additions & ADU Company
We’ve worked on enough Gladeview homes to know the routine: pull up to a 1958 concrete block house on NW 62nd Street, open the electrical panel, and find galvanized plumbing still in service. The homeowners are usually the second or third family to own the place. They want to add space for aging parents or rental income, and they’ve already talked to a contractor who quoted them a number without mentioning hurricane strapping or impact-rated windows.
That doesn’t happen with our clients. We handle ADU design, permitting, and construction as a single-source contractor, which means one accountable team from first sketch to final county sign-off. Our Home Additions & ADU crew has navigated Miami-Dade’s NOA portal for hundreds of product approvals and knows which inspection codes trigger which upgrades on 1950s-60s CBS construction.
We don’t subcontract out the hard parts or spec whatever materials are in the warehouse that week. You choose the brand, we handle the build. For Gladeview homeowners, that means KraftMaid or Wellborn cabinetry in a garage conversion kitchenette, Cambria countertops in a junior ADU, and James Hardie siding on a new detached unit - all specified with county-approved products before we break ground.
Raymond Estevez has built Groundwork’s process around the reality of unincorporated Miami-Dade construction: no city building department to call for clarification, so our team builds that expertise in-house.
Our Home Additions & ADU Services in Gladeview
ADU Design & Permitting
Every ADU in Gladeview starts with Miami-Dade County permits, not city ones. Because Gladeview is unincorporated, we file directly with the county, navigate the HVHZ compliance worksheet, and spec every window, door, and roofing product through the NOA portal before submission. A typical attached ADU or garage conversion permit package includes wind-load calculations, impact-rated opening schedules, and roof-to-wall connection details that most designers miss on their first pass. We don’t.
Garage Conversion ADU
Garage conversions are popular in Gladeview’s 33147 zip code, where original 1950s carports and enclosed garages offer ready-made footprints. But converting that space to habitable square footage triggers full HVHZ compliance on the entire structure, not just the new room. On a 1956 CBS home near NW 62nd Street and 17th Avenue, our crew pulled permits through Miami-Dade County’s online portal and replaced a failing jalousie window wall with a NOA-approved impact-rated sliding glass door on the new ADU’s south elevation. We also had to retrofit the existing roof-to-wall connections with Simpson Strong-Tie straps - a step the county inspector verified on-site - after discovering the original flat built-up roof had no hurricane strapping. That’s the level of forensic detail garage conversions here demand.
New Detached ADU
Detached ADUs in Gladeview face the strictest wind-load standards in the continental U.S. We offer two build paths: traditional stick-framed construction with full HVHZ engineering, or prefab units from Abodu, Dvele, Mighty Buildings, or Boxabl that arrive with Miami-Dade NOA approval already in hand. The prefab route can compress the timeline significantly, but either way, the foundation must account for Gladeview’s high water table and summer drainage patterns. We’ve seen too many slabs poured without proper vapor barriers in this neighborhood.
Junior ADU & Interior Conversion
For homeowners who don’t want exterior construction, we convert existing interior space into self-contained junior ADUs. In Gladeview’s older CBS homes, this often means rerouting original cast-iron plumbing, upgrading electrical service to 200-amp panels, and adding separate HVAC zones. The work is less visible than a ground-up build but requires the same permit rigor and the same attention to what walls are load-bearing in these decades-old block structures.

Trusted Brands We Service in Gladeview
Groundwork works with 50+ recognized industry brands across every project category, and we don’t lock Gladeview homeowners into proprietary lines. For ADU kitchens, that means KraftMaid or Wellborn cabinetry with Cambria, Silestone, or Caesarstone countertops - your choice, your budget tier. Exterior finishes draw from James Hardie siding, Andersen or Pella windows, and GAF or CertainTeed roofing, all spec’d through Miami-Dade’s NOA portal before we order. This matters in Gladeview more than most places. A window without county approval sits in a warehouse while your permit stalls. We verify every product number upfront.
Common Home Additions & ADU Problems We See in Gladeview Homes
- NOA non-compliance on windows and doors. Out-of-area crews spec attractive products without checking Miami-Dade’s online NOA portal, then face failed inspections and costly material swaps on the job site. We verify every SKU before it ships.
- Underestimating HVHZ trigger scope. Contractors quote an ADU as simply “adding square footage” to a 1960s CBS slab, ignoring that any permitted work forces full compliance with wind-load requirements - including upgraded openings and connections the original home never had.
- Inspection scheduling errors. Crews unfamiliar with unincorporated Miami-Dade schedule inspections through the county’s centralized system at the wrong status or request the wrong inspection type, causing delays and re-inspection fees because Gladeview has no local building department to catch the mistake.
- Moisture and spalling in original slabs. Gladeview’s high water table and summer standing water accelerate concrete degradation. We routinely find rebar corrosion and subfloor moisture intrusion when opening up 1950s slabs for addition foundations.

FAQs - Home Additions & ADU in Gladeview
Yes, every ADU requires a building permit issued by Miami-Dade County, not a city office, because Gladeview is unincorporated.

Call (844) 665-0162 and we’ll walk you through the permit timeline for your specific project.
Most Gladeview homes from this era need roof-to-wall connection upgrades with engineered straps or clips, impact-rated windows or shutters on all openings, and often a full roof replacement to meet current HVHZ standards. We assess these requirements during our initial site visit and include them in our permit package. Call (844) 665-0162 for a free evaluation of your home’s current compliance status.
Yes, if the structure meets setback, height, and parking requirements under Miami-Dade County code.

We evaluate the existing slab, roof structure, and utility capacity before quoting. Call (844) 665-0162 to schedule a site assessment.
They spec products without verifying Miami-Dade NOA approval, then fail inspection and must substitute county-approved alternatives at the last minute. We check every product number in the NOA portal before ordering, so what arrives is what gets installed. Call (844) 665-0162 - we build to spec, not to convenience.
Standard ADU permit review through Miami-Dade County typically takes 4-8 weeks for complete submissions, but incomplete packages - missing HVHZ worksheets or unverified product approvals - can stretch to 12 weeks or longer. Our pre-submission checklist catches these gaps before filing. Call (844) 665-0162 and we’ll review your project’s likely timeline.
