Why Groundwork Construction Co. of South Florida Is Melrose Park’s Preferred Home Additions & ADU Company
We’ve built our reputation in Broward County by treating Melrose Park’s unique regulatory landscape as standard operating procedure, not an afterthought. Homeowners here tell us the same thing: out-of-area contractors quote fast, then disappear for weeks when they realize permits don’t run through a city hall.
Our response time to Melrose Park is same-day for consultations, because we’re already working in neighboring Davie and Lauderdale Lakes. We know the 33308 zip and the concrete block homes along corridors like 27th Terrace and NW 19th Street. That local familiarity means we spot the hidden issues before they become change orders: the original flat roof that needs tying into new construction, the 1960s electrical panel that won’t carry an ADU load, the non-impact doors that’ll fail county inspection.
Raymond Estevez built Groundwork on the principle that one contractor should handle every phase, from driveway to roofline. In Melrose Park, that means one permit strategy, one inspection schedule, one point of accountability.
Our Home Additions & ADU Services in Melrose Park
ADU Design & Permitting
Every ADU in Melrose Park starts with Broward County’s Building Division, not a municipal office. We handle the full design package, HVHZ compliance documentation, and county submission. Because we work this portal regularly, we know the reviewers by name and the common rejection triggers. Our Home Additions & ADU team prepares impact-rated door specs, wind-load calculations, and utility separation plans as part of the initial submittal, not as corrections after the fact.

Garage Conversion ADU
Garage conversions in Melrose Park face a specific hurdle: the existing garage door almost never meets HVHZ standards, and simply walling it off doesn’t solve the problem. We replace it with a rated assembly or design a new opening that satisfies county inspectors. Most garage conversions here run $30,000-$80,000 depending on whether we’re extending slab, upgrading electrical, and adding kitchen and bath rough-ins.

New Detached ADU
Detached ADUs give Melrose Park homeowners rental income or multigenerational space without sacrificing the main house. We offer two build paths: traditional stick-frame construction or prefab units from partners like Mighty Buildings, Boxabl, and Plant Prefab. Prefab can compress the build schedule significantly, but still requires the same Broward County foundation and utility permits. We manage both tracks.

Junior ADU & Interior Conversion
For homeowners who don’t want exterior construction, junior ADUs convert existing interior space with a separate entrance and kitchenette. In Melrose Park’s 1950s-1970s CBS homes, we often find these work best when combined with electrical service upgrades and impact-rated door replacements that the county requires anyway during permitted work.

ADU Site Prep & Utilities
This is where Melrose Park’s geography gets real. The water table sits 2-4 feet below grade across much of Broward County. Footings for a detached ADU almost always require dewatering, engineered fill, or raised stem walls. We price this upfront based on geotechnical observation, not as a surprise mid-project. Utility trenching faces the same challenge, plus coordination with Broward County’s separate utility permit for ADU water and sewer connections. Skip that second permit and you’ll get a stop-work order. We don’t skip it.

Room Additions & Second Story Additions
Room additions in Melrose Park must tie into existing CBS walls and flat or low-slope roofs with proper lateral load transfer. Second stories are feasible on many slab-on-grade homes here, but require structural analysis of the existing foundation. We bring in our engineering partners early, before you’ve committed to a design that won’t work.

Sunrooms & Enclosed Patios
Even a modest sunroom enclosure triggers HVHZ requirements in Melrose Park. We use impact-rated windows from Andersen, Pella, or PGT, and design roof connections that’ll pass county inspection. The difference between a three-season space and a year-round room is in the insulation, HVAC tie-in, and whether the slab gets a proper thermal break.

Common Home Additions & ADU Problems We See in Melrose Park Homes
- Original non-impact doors fail HVHZ inspection. That hollow-core front door from 1962 won’t pass. We replace it with a wind-rated assembly tied to reinforced framing, or the county won’t issue your certificate of occupancy no matter how nice the new addition looks.
- Site prep footings hit the water table. You start digging for ADU footings and water appears at 30 inches. We plan for this with dewatering systems, engineered fill, or raised foundations priced into the original estimate.
- Crews miss the separate utility permit. Broward County requires a distinct permit for ADU water and sewer connections. General contractors used to city workflows often overlook this. We file both permits simultaneously.
- Flat roof tie-ins leak within two years. Melrose Park’s original low-slope roofs need careful detailing where new construction meets old. We remove enough existing roofing to get proper overlap and membrane continuity, not just sealant and hope.

FAQs - Home Additions & ADU in Melrose Park
Yes. Because Melrose Park is unincorporated, all construction permits including garage conversions run through the Broward County Building Division, not a city office. We prepare and submit your full package, including HVHZ compliance docs, impact-rated door specs, and electrical load calculations. Call (844) 665-0162 to start the process.
Broward County’s HVHZ code requires all exterior doors on the structure to meet wind and impact standards when significant construction triggers a full permit. The county treats the building as a single system. During a pre-storm inspection on a 1960s CBS home near 27th Terrace, our tech found the original facade door had no impact rating, just a hollow-core slab. We reinforced the frame and fitted a new wind-rated entrance, tied the addition’s roof to existing block walls, and pulled a Broward County permit, approval in days, not weeks.
Broward County’s water table sits 2-4 feet below grade, so standard footings often require dewatering, engineered fill, or raised stem walls. We investigate soil conditions during our initial site visit and price the foundation appropriately. Unexpected water infiltration is the single biggest source of ADU cost overruns in this area, and we don’t let it surprise you.
No. The existing garage door assembly won’t pass HVHZ inspection, and simply framing it in place doesn’t satisfy code. We replace it with a rated wall assembly or design a compliant opening with an impact-rated door. This is non-negotiable for county approval.
Oakland Park has its own municipal building department with its own reviewers and inspection schedule. Melrose Park, being unincorporated, uses Broward County’s system entirely. The county portal has different document requirements, longer initial review times, and separate utility permits that Oakland Park handles internally. Contractors who regularly work Oakland Park often stumble on the county workflow. We’ve built our process around both. Call (844) 665-0162 and we’ll walk you through exactly what your project needs.
