ADU Builders Near Me in Fort Myers - Design, Permits and Build Under One Contract

Don’t Hire an ADU Builder in Fort Myers Until You Run This License Check

Finding ADU Contractors Near Me in Fort Myers, FL starts with a step most search results won’t tell you: verifying the contractor’s state license through Lee County’s online portal before anyone walks your property. After Hurricane Ian, Lee County and the Florida DBPR ran joint enforcement sweeps targeting unlicensed crews who specifically targeted ADU and addition projects, and homeowners who skipped that check are still dealing with half-built units and failed inspections. At Groundwork Construction Co. of Fort Myers, we’re fully licensed, locally rooted, and our background-checked technicians show up in uniform every time. Call (844) 638-7249 and we’ll walk you through our license credentials on your first call.

What Happened to Fort Myers After Ian, and Why It Still Matters for Your ADU

After the 2022 storm, an enormous pool of insurance payouts and rebuild capital flooded Lee County. Unlicensed crews from out of state followed that money. The pattern was consistent: they’d approach homeowners with below-market ADU pricing, collect deposits of $10,000 to $30,000, do partial work or none at all, and vanish before the first inspection was scheduled. Fort Myers homeowners were hit harder than almost any other Florida market because the sheer volume of available rebuild money made us a target. The county’s contractor licensing search tool exists for exactly this reason, and we tell every homeowner we meet to use it. Search any builder’s name, confirm they hold an active CGC or CBC license with no disciplinary actions, and verify workers’ comp and liability insurance are current. If a contractor hesitates when you ask for their license number, that’s your answer.

Derek Hollenbeck grew up in the Iona area and has spent his entire career building in Lee County. He learned the fundamentals at Lorenzo Walker Technical College in Naples and has been running crews and managing residential projects here ever since. When he says Groundwork is licensed, insured, and accountable, he means it’s verifiable on a state database in thirty seconds. That matters in a market where too many homeowners have learned the hard way that a cheap out-of-state bid isn’t worth the paper it’s printed on.

What an ADU Actually Costs in Fort Myers Right Now

ADU Cost in Fort Myers, FL typically runs between $90,000 and $220,000, depending on size, foundation type, and finish level. That’s a real range, not a teaser number designed to get you on the hook. We’ve built enough accessory units across Lee County to know exactly where costs fall, and we’ll give you upfront pricing with no surprises before any work begins. Here’s how the numbers break down for the most common ADU approaches in our area:

• Garage conversion (finished): $30,000-$80,000 - usually the fastest path to an ADU if the existing slab and framing are in good shape
• Detached new-build ADU (studio/one-bed): $90,000-$160,000 - includes foundation, utilities tie-in, and full finishes
• Detached two-bedroom ADU with kitchen and bath: $150,000-$220,000 - higher end due to plumbing rough-ins, separate HVAC, and impact-rated openings
• Attached addition ADU (shares a wall with the primary residence): $45,000-$130,000 - cost varies heavily based on whether you’re adding a bath and kitchen or just living space

Fort Myers sits in a Wind-Borne Debris Region requiring 160+ mph design wind speeds, and much of the city is in FEMA AE and VE flood zones. That means your ADU’s finished floor elevation may need to clear Base Flood Elevation plus freeboard, especially after FEMA’s post-Ian advisory maps raised BFEs by two to four feet in many parcels. We factor this into our pricing from day one. No mid-project surprises about elevation certificates or foundation replatting, because we’ve been navigating Lee County’s updated permitting pipeline since those maps dropped.

What Groundwork Brings That Most ADU Builders Don’t

Our home base is here in Fort Myers. When you call us, a live person answers. That’s true at 2 p.m. on a Tuesday and it’s true at 9 p.m. on a Saturday if something comes up on your job site. The post-Ian market taught a lot of homeowners what happens when your contractor’s phone goes to voicemail and stays there. We built our 24/7 live-answer commitment specifically so that never happens to our clients.

We also stand behind every ADU with our 730-Day Done Right Promise. If it’s not done right, we make it right. That guarantee is in writing and it’s tied to a local licensed contractor with a physical presence in Fort Myers, not a national prefab company routing warranty claims to a P.O. box in another state. Enforcement is a real conversation with a real person here, and we’ve been doing this long enough that our reputation depends on it.

Our technicians are background-checked, uniformed, and arrive in clearly marked vehicles. In a market where unmarked vans and handshake deals burned too many homeowners, that visibility is a deliberate choice. For materials, we use a curated set of proven brands. Depending on your ADU’s design, that might include James Hardie siding, Andersen windows, or GAF roofing. We don’t cut corners on materials because the 730-Day Done Right Promise means we’re tied to the outcome for two full years.

Common ADU Scenarios We See in Fort Myers Neighborhoods

Across the McGregor corridor, we regularly hear from homeowners with 1950s concrete block homes who want to add an Home Additions & ADU for aging parents. The challenge is tying modern hurricane-strap requirements into an older tie-beam block structure, and we’ve solved that enough times to have a clear process for it.

In newer master-planned communities built to post-2002 Florida Building Code standards, the conversation is usually about detached ADUs as rental income units. HOA and zoning restrictions vary by development, and we help homeowners navigate those before we ever break ground.

Manufactured and mobile home properties, which took the worst of Ian’s damage, present a different set of questions entirely, usually about whether an ADU is even feasible on the parcel under current flood zone and elevation rules. We’ll give you a straight answer on that, not a sales pitch that ignores the reality of your lot.

We don’t just break ground, we build something worth standing on. That’s been the approach since Derek started Groundwork, and it’s how we’ve earned the trust of homeowners across Lee County who’ve seen what happens when the wrong contractor gets the job.
