North Andrews Gardens sits in unincorporated Broward County, which means every addition, garage conversion, and ADU we build here goes through county-level permitting, not a city building department. That distinction matters. We’ve worked the 33334 zip code long enough to know which county inspectors focus on tie-down details versus moisture-barrier documentation. Our crews are on NE 14th Court, NW 39th Street, and the streets around North Andrews Gardens Park regularly. When you’re expanding a 1960s CBS home or converting a garage that hasn’t been touched since the Carter administration, local permitting fluency saves weeks.
Why Groundwork Construction Co. of South Florida Is North Andrews Gardens’s Preferred Home Additions & ADU Company
We’ve built a reputation in North Andrews Gardens by showing up prepared for what this specific neighborhood throws at contractors. The modest single-story CBS homes built from the late 1950s through the 1970s dominate the blocks here, many with flat roofs and original windows that predate Hurricane Andrew code reforms. Homeowners here aren’t looking for flashy; they’re looking for someone who understands that adding 400 square feet to a 1962 block house means dealing with county inspectors who remember every HVHZ revision since 1994.
Our response time to North Andrews Gardens calls typically runs same-day or next-day for initial consultations. We’re not sending a salesperson from Miami-Dade who can’t find NE 14th Avenue without GPS. Our project managers know the difference between a county permit routing and what Oakland Park requires three blocks east.
Raymond Estevez, who leads Groundwork Construction Co., has directed additions and ADU projects across unincorporated Broward long enough to anticipate the compliance traps that snag less experienced contractors. That institutional knowledge shows up in permit applications that get approved the first time, not the third.
Our Home Additions & ADU Services in North Andrews Gardens
ADU Design & Permitting
Every ADU in North Andrews Gardens starts with Broward County Building and Code Compliance Division paperwork, not a city hall submission. We handle the full design-permit-build sequence in-house. Our team prepares HVHZ-compliant structural plans, coordinates with county inspectors, and navigates the wind-mitigation documentation that older homes often lack. Because we’re familiar with county routing times, we build realistic schedules instead of promising what we can’t deliver.
Garage Conversion ADU
Garage conversions in North Andrews Gardens carry a specific risk: unpermitted work from the 1970s-80s triggers full county code compliance the moment we pull a new permit. We’ve seen homeowners blindsided by this. Our process includes a pre-permit site review to identify existing conditions that county inspectors will flag. We convert garages into legal dwelling units with proper egress, moisture barriers for the high water table, and tie-ins to existing utilities that meet current code.
New Detached ADU
Detached ADUs on North Andrews Gardens lots demand careful site prep. The water table here sits just a few feet below grade on the flat coastal plain. We engineer slab and foundation systems with drainage plans that prevent heave and moisture intrusion. Our prefab partnerships with Abodu, Dvele, Mighty Buildings, and Boxabl offer fast-track options, or we stick-build to spec using materials you select from our 50+ brand roster.
Junior ADU & Interior Conversion
Junior ADUs work well in North Andrews Gardens’s smaller CBS homes where a separate entrance can be added without expanding the footprint. We handle interior reconfigurations, kitchenette installations with KraftMaid or Wellborn cabinetry, and bathroom additions that tie into existing plumbing stacks. Every interior conversion we touch gets evaluated for impact-rated window upgrades, since county code often requires them when the building envelope is modified.
Room Additions
Room additions on North Andrews Gardens homes demand particular attention to roof tie-ins. Those flat or low-slope roofs on 1960s-70s construction often lack proper tie-downs for current wind loads. We engineer connections that don’t just add space but strengthen the existing structure against hurricane forces. Our Home Additions & ADU team coordinates roofing, window, and structural work as a single sequence.
Sunrooms & Enclosed Patios
Enclosing a patio in North Andrews Gardens means more than adding walls. County HVHZ standards require impact-rated glazing and proper anchoring to the existing slab. We use PGT, CGI, or other impact-rated window and door lines to ensure the new space doesn’t become the weak link in your home’s storm defense. Raymond Estevez reviews every sunroom enclosure for wind-load continuity before we submit plans.

Trusted Brands We Service in North Andrews Gardens
We don’t lock North Andrews Gardens homeowners into proprietary products. You choose the brand, we handle the build. For cabinetry in ADU kitchenettes, we stock KraftMaid and Wellborn lines with local supplier relationships that keep lead times predictable. Countertops draw from Cambria, Silestone, and Caesarstone engineered quartz options across multiple price tiers. Exterior cladding on additions frequently specifies James Hardie fiber-cement siding for its HVHZ approval and durability in South Florida’s salt-air environment. Our brand roster spans 50+ recognized manufacturers, so your addition gets built to spec, not to convenience.
Common Home Additions & ADU Problems We See in North Andrews Gardens Homes
- Unpermitted legacy work triggers full compliance. That garage conversion from 1978 with no permit? The moment we pull a new county permit for any addition, inspectors will require the entire property to meet current code. We catch this early and build the retrofit into our scope, not as a mid-project surprise.
- Original windows and doors become the failure point. Adding a room or ADU without upgrading existing openings to impact-rated models leaves the whole structure vulnerable. We specify Andersen, Pella, Marvin, or impact-rated PGT and CGI lines so wind and debris don’t breach your home at its weakest points.
- High water table undermines ground-level additions. North Andrews Gardens’s flat, low-elevation lots need engineered moisture barriers and drainage plans for any slab work. We don’t pour until the geotechnical realities are addressed.
- Flat-roof tie-downs fail to meet current standards. Those 1960s CBS homes with low-slope roofs often lack the hurricane straps and connections that county inspectors now enforce. Our structural team engineers proper tie-ins so your addition strengthens, not weakens, the roof system.

FAQs - Home Additions & ADU in North Andrews Gardens
Yes. Because North Andrews Gardens is unincorporated, all garage conversion ADUs require permits through the Broward County Building and Code Compliance Division, not a city office. The county will inspect for full code compliance including egress, moisture barriers, and HVHZ-rated openings. Call (844) 665-0162 and we’ll walk you through the specific documentation needed for your property.
New ADU windows in North Andrews Gardens must meet Broward County’s High-Velocity Hurricane Zone (HVHZ) standards, which typically means impact-rated products or protected openings with approved shutters. We specify PGT, CGI, or equivalent impact-rated lines that carry Miami-Dade and Broward County product approvals. Non-compliant materials will fail inspection and delay your project.
Yes, but the foundation and drainage design must account for it. North Andrews Gardens’s flat coastal plain puts the water table within a few feet of grade on many lots. We engineer raised slabs, enhanced moisture barriers, and perimeter drainage systems that prevent heave and intrusion. The added cost typically runs $3,000-$8,000 above standard slab prep.
It can, if the tie-in isn’t engineered properly. Many North Andrews Gardens homes have flat or low-slope roofs from the 1960s-70s with inadequate hurricane straps. Our structural team evaluates existing tie-downs and upgrades connections as needed so the addition reinforces, rather than compromises, the roof’s wind resistance. County inspectors will verify this before final approval.
Unpermitted garage conversions from the 1970s-80s in North Andrews Gardens trigger full county code compliance when any new permit is pulled. Inspectors will require current electrical, plumbing, egress, and HVHZ standards throughout the structure, not just the new work. We identify these conditions during pre-permit review and build the necessary retrofits into our project scope from day one. Call (844) 665-0162 for a compliance assessment before you apply.
