Licensed Home Additions & ADU When South Florida Homeowners Need It Most
Last hurricane season, a family in Hollywood called us after their converted garage flooded. The “contractor” who’d built it had skipped permits, used interior-grade materials, and vanished. We see this story repeat across Broward and Miami-Dade counties more often than we’d like. At Groundwork Construction Co. of South Florida, we’ve spent years rebuilding trust alongside homes through our Home Additions & ADU services, and our phone at (844) 665-0162 hasn’t stopped ringing from homeowners who’ve learned the hard way that cheap and fast usually means expensive and twice.
What Makes a Home Additions & ADU Company the Best in South Florida?
- Proper Florida state licensing. Florida requires a certified general contractor license for any residential construction over $1,000. Unlicensed operators flood South Florida after every storm, undercutting legitimate builders by skipping permits and inspections. We maintain active state licensure, pull every required permit, and schedule inspections that protect your investment and your safety. Our work gets signed off by municipal inspectors in Fort Lauderdale, Miami, Pembroke Pines, and every city we serve.
- Insurance and bonding that actually covers you. Any company can claim they’re “fully insured.” What matters is whether their policy protects you when a worker gets injured on your property or when a structural defect appears two years later. We’re insured and bonded, and we’ll provide proof of coverage before any contract gets signed. In South Florida’s litigious environment, this isn’t optional, it’s survival.
- Verified reputation with real South Florida homeowners. Reviews matter, but context matters more. Look for detailed feedback mentioning specific neighborhoods, project types, and how the company handled problems. We’ve built additions from Coral Gables to Boca Raton, and our customers talk about our communication, our cleanup, and our willingness to explain code requirements they didn’t know existed.
- Warranty that outlasts the honeymoon period. Many South Florida contractors offer a one-year warranty because that’s when Florida law requires them to. We stand behind our structural work and our ADU builds with coverage that reflects our confidence. A real warranty has a real phone number that reaches a real person. Ours does.
- Response time that respects your timeline. South Florida’s housing market moves fast. Zoning changes, interest rates, and family needs don’t wait for a contractor who “might get back to you next week.” We return calls within hours, not days, and we show up when we say we will. For homeowners comparing options, that reliability separates the professionals from the pretenders.

What South Florida Customers Say
“We interviewed four companies for our mother-in-law suite in Miramar. Three gave us estimates without ever measuring. Groundwork Construction Co. of South Florida spent two hours understanding how my mother would actually use the space, then pointed out that our original plan violated setback rules we’d never heard of. They saved us from a $15,000 redesign.” – a South Florida homeowner
“Our ADU in Fort Lauderdale needed to withstand flooding we get on our street every September. The previous contractor’s quote didn’t even mention elevation requirements. These guys knew the code, knew the inspector, and had us permitted in three weeks.” – a South Florida homeowner
“I was skeptical after my neighbor’s addition leaked in the first rain. Groundwork showed me their moisture barrier details, explained why they don’t use certain flashing methods that fail in our salt air, and walked the job with me weekly. Sixteen months later, dry as a bone.” – a South Florida homeowner
How We Compare to Other Home Additions & ADU Companies in South Florida
The difference between a project you’ll brag about and one you’ll litigate over usually shows up before anyone swings a hammer.
Red flags we see too often in South Florida: Contractors who pressure you to start before permits are issued, who can’t explain why your ADU needs impact-rated windows, who quote suspiciously low by omitting required engineering, or who subcontract everything to crews you’ve never met. Some “companies” are just a guy with a truck and a website, uninsured and unaccountable when things go wrong.
How we operate instead: Every project gets a dedicated project manager who lives in South Florida and answers their phone. We use established prefab partners like Plant Prefab and Mighty Buildings when their systems suit the site and budget, but we never force a solution that doesn’t fit, and we’ll walk you through the Prefab ADU vs Custom Built ADU in South Florida, FL trade-offs for your specific project. Our pricing includes all permits, inspections, and code-required upgrades, so the number you approve is the number you pay. We’ve walked away from jobs where the homeowner insisted on skipping steps that would haunt us both later.
In a market flooded with options after every storm season, we’ve chosen to build slowly and sustainably. That choice costs us some jobs to lower bidders. It also means we’re still here, still licensed, still answering our phones, when those other contractors have changed their business names and moved on.
Frequently Asked Questions - Licensed Home Additions & ADU in South Florida
Most permitted home additions in South Florida range from $180 to $350 per square foot depending on foundation requirements, hurricane-impact specifications, and whether you’re building up or out. ADUs typically run $220 to $400 per square foot because they require full kitchens, bathrooms, and separate utility connections. Call (844) 665-0162 for an exact quote on your specific property, estimates are free.
Yes, Florida law requires a licensed general contractor for any residential construction exceeding $1,000, and all ADUs require permitted electrical, plumbing, and structural work. Unlicensed work can void your homeowner’s insurance, block future sales, and force expensive remediation. We handle every permit and inspection required by your specific municipality.
From permit approval to final inspection, most South Florida ADUs take four to seven months. Permitting itself adds six to twelve weeks depending on whether you’re in Miami-Dade, Broward, or Palm Beach County, and whether your property requires zoning variances. We start the pre-application process before construction begins to compress that timeline.
Maybe, and we’ll tell you honestly. South Florida’s zoning varies block by block, some areas restrict ADUs entirely, others require owner occupancy of the main house, and flood zones add elevation requirements that make some lots prohibitively expensive. We research your specific parcel before quoting, so you don’t pay for plans that can’t be built.
Room Additions are usually 15 to 30 percent less expensive because they share existing foundations, utilities, and roofs. Detached ADUs cost more but offer rental income potential and privacy that additions can’t match. For South Florida homeowners weighing this decision, we analyze your lot, your zoning, and your long-term goals before recommending either path. Call (844) 665-0162 to walk through the numbers for your situation.
