What a garage conversion ADU actually costs and involves in Verona Walk, FL
A garage conversion ADU in Verona Walk, FL typically runs between $30,000 and $80,000 depending on the existing space, and most projects take 8 to 16 weeks from the day we pull permits. That number reflects turning a standard attached garage into a fully permitted, conditioned living unit with a kitchenette, bathroom, sleeping area, and its own entrance. It’s a real apartment when we’re done — not a finished room with a mini-fridge. Call (844) 638-7249 and we’ll walk your specific garage and give you a written line-item estimate, no charge.
How a Verona Walk garage conversion goes from parking space to living space
Most homeowners have never done this before, so we’re direct about what happens and when. Every garage conversion ADU we build in Verona Walk follows the same five-stage process, but the timeline shifts based on what’s behind those DiVosta walls.
Stage 1: Site measure, existing-condition survey, and permit drawings (2-3 weeks). We laser-measure the entire garage, document the slab elevation relative to the main house, map every electrical circuit, and locate plumbing stubs. From there our draftsman produces the architectural set the county and your HOA need to see. You’ll sign off on the floor plan, the window and door schedule, and the finish schedule before anything leaves the office.
Stage 2: HOA review and Collier County permit submission (4-6 weeks, concurrent where possible). Verona Walk has a mandatory architectural review committee. We submit the same drawing package to them while the county reviews for structural, wind-load, and flood-zone compliance. If the garage slab sits below the Base Flood Elevation on your survey, the county will require a flood opening or dry-floodproofing detail in the plans. We handle the back-and-forth. You shouldn’t have to learn the FEMA flood manual to get your ADU approved.
Stage 3: Demolition and rough-in (1-2 weeks). The garage door comes out. If the slab needs to be raised or leveled to match the main house floor, we do it here. We frame the new wall where the door was, core-drill any new exterior penetrations through the poured concrete, and rough in the plumbing, electrical, and mini-split HVAC. The water heater and subpanel get placed so the ADU operates independently from the main house. First inspection happens at the end of this stage.
Stage 4: Insulation, drywall, finishes, and trim (3-5 weeks). Closed-cell spray foam on the exterior walls (required to hit code in a high-velocity hurricane zone conversion), then drywall, taping, and texture. Flooring goes down, the kitchenette cabinets and countertops go in, bathroom tile and fixtures get set, doors hung, baseboards and casing installed. Your finish choices earlier — cabinet door style, countertop material, floor type — all land here.
Stage 5: Final MEP trim-out, punch list, and county final inspection (1-2 weeks). Light fixtures, switches, faucets, appliances connected and tested. The mini-split gets commissioned. We walk the unit with you, build a punch list, and knock it out. County inspector signs off. Keys handed over.
The options you’ll choose between for your garage conversion ADU
Every choice you make affects the total cost and how the unit lives day to day. Here are the ones that matter most, with honest trade-offs:
- Kitchenette or full kitchen. A kitchenette with a sink, undercounter fridge, microwave, and two-burner cooktop keeps costs lower and works for a guest suite. A full kitchen with a range, dishwasher, and vent hood adds $4,000-$8,000 but makes the ADU a true long-term rental.
- Bathroom: three-quarter or full. A shower, toilet, and vanity is standard and sufficient for most ADUs. Adding a tub pushes the rough-in and finish cost up $1,500-$3,000 and eats more floor space. Worth it if the ADU is for aging parents; usually not for a rental.
- Flooring: luxury vinyl plank vs. tile. LVP is quieter underfoot, warmer, and costs less to install. Tile handles standing water better and lasts longer, but it’s cold and requires a flatter slab. In Verona Walk garages where slab leveling was needed, LVP often makes more sense because it forgives small substrate imperfections.
- Mini-split vs. tying into the main HVAC. A dedicated ductless mini-split costs $3,000-$5,000 installed and gives the tenant independent temperature control. Tapping the existing central system saves upfront money but creates disputes over the thermostat and may overload an older unit that was never sized for the extra square footage.
- Impact-rated entry door and windows. If the garage already has a window that isn’t impact-rated, the county will flag it during plan review. An impact-rated French door or single-entry door with sidelights runs $1,800-$4,500 depending on size and brand. This isn’t optional in a high-velocity hurricane zone; skip it and the permit dies on the reviewer’s desk.
What a garage conversion ADU costs in Verona Walk, FL
A straightforward conversion of a clean, dry attached garage with easy plumbing access and an already-level slab lands around $45,000-$55,000. The high end — $70,000 to $80,000 — is where we’re raising a slab, relocating the water heater and electrical panel, adding a full kitchen, or working in a detached garage that needs a new foundation and utility trench. Here’s what moves the number:
- Garage size. A single-car garage (roughly 240-300 sq ft) converts for less than a two-car (400-500 sq ft) simply because there’s less of everything — less flooring, less drywall, fewer linear feet of baseboard. The cost-per-square-foot drops on larger spaces, but the total check goes up.
- Plumbing distance. If the main sewer stack is on the opposite side of the house from the garage, running a new drain line means cutting a trench across the slab or through exterior walls. That alone can add $3,000-$6,000.
- Electrical service. Most Verona Walk homes built between 2004 and 2009 have 200-amp panels. If your panel is full or undersized, a subpanel or service upgrade adds $1,500-$3,500 before we wire a single outlet.
- Slab condition and elevation. We’ve opened garages here where the slab sloped aggressively toward the door or sat several inches below the main living floor. Leveling or pouring a raised floor assembly adds cost fast.
- Finish level. Stock cabinets, laminate counters, and basic LVP keep the budget in the $45,000 range. Custom cabinetry, quartz or solid-surface counters, and upgraded tile push toward $65,000+.

What Verona Walk’s DiVosta construction does to a garage conversion
Verona Walk is almost entirely a DiVosta Homes community, and that matters the minute we put a diamond blade to the wall. DiVosta used a poured-concrete wall system — solid monolithic concrete, not hollow CMU block. When we need to cut a new exterior door opening where the garage door was, or run a plumbing vent through an exterior wall, we’re core-drilling through solid concrete - something we’ve learned from every Iron Fence in Verona Walk and similar project we’ve done here. It takes longer than notching block, it wears blades faster, and it’s work a block-mason crew that doesn’t know DiVosta will price wrong every time. We build that labor into the estimate from day one because we’ve done it here.
The HOA architectural review adds a step most cities don’t have. Before Collier County will look at a permit application for a garage conversion ADU, the Verona Walk architectural committee needs to approve the exterior changes — the new door and window placement, the exterior finish, the paint color. That review runs on its own clock, and it’s not unusual for it to add two to three weeks to the schedule. We submit the HOA package and the county package concurrently so the waits overlap as much as possible.
We also see the same age-related issues across the community now. Homes built between 2004 and 2009 are hitting the point where original water heaters, HVAC air handlers, and garage-door openers are failing. If your water heater is in the garage and it’s 18 years old, we’re going to recommend replacing it as part of the conversion rather than building a finished wall in front of a tank that’s living on borrowed time. It’s cheaper to do it now than to tear out drywall later.

Frequently asked — Garage Conversion ADU in Verona Walk
Yes, and you need two approvals. The Verona Walk HOA architectural committee must approve the exterior changes first, and then Collier County issues the building permit. Skipping either one means the work is unpermitted, which creates problems when you sell the home or if a storm damages an uninspected assembly. We handle both applications as part of the project.
Most conversions take 8 to 16 weeks from permit submission to final inspection. The HOA review and county permit review run concurrently and take 4-6 weeks combined. Actual construction typically spans 5-8 weeks once the permit is issued, depending on how much slab work and plumbing relocation the specific garage requires.
You can, if the floor plan allows the bathroom and kitchenette to sit on the wall closest to the existing sewer stack. That keeps the drain-line run short and avoids cutting through a large section of slab. A wet bar or kitchenette that shares a wall with the bathroom also saves plumbing cost. We’ll lay out both options during the site measure so you can decide based on real numbers.
A typical attached-garage conversion in Verona Walk runs $45,000-$80,000 depending on size, plumbing distance, slab work, and finish level.

Call (844) 638-7249 for a written estimate specific to your garage.
