What a new detached ADU in Verona Walk actually costs and how long it takes
A new detached ADU in our Verona Walk service area typically runs between $45,000 and $130,000, with most full-permit projects landing between $90,000 and $120,000. That range covers a self-contained unit with its own kitchenette, bathroom, living space, and separate entrance, built to current Florida Building Code and Collier County’s wind-load and flood-elevation standards. Permitting, site prep, foundation, and utility extensions are included in a properly scoped bid, and the build itself usually takes 14 to 22 weeks from permit issuance to final inspection. If you want a hard number for your specific lot, call (844) 638-7249 and we’ll walk it together.
How we build a new detached ADU in Verona Walk, start to finish
1. Site evaluation and feasibility (Days 1-5)
We start by pulling your property’s FEMA flood zone designation, lot coverage limits, and setback requirements from Collier County records. Because most Verona Walk parcels sit within or adjacent to a Special Flood Hazard Area, we verify the finished floor elevation against your existing elevation certificate. If you don’t have one, we order it now. This first week tells us what size and placement your ADU footprint actually allows, and whether we’ll need fill, piers, or a stem-wall foundation to meet code.
2. HOA architectural review and Collier County permitting (Weeks 1-6)
Verona Walk’s HOA has a formal architectural review board that must sign off before Collier County will even look at your permit application. We prepare the submittal package with exterior elevations, finish schedules, roof style, window specs, and drainage plans in the exact format the ARB expects. Once approved, the county permit review takes over. Expect plan-check comments on wind-load assemblies, impact-rated openings, and floodplain compliance. We respond to every comment directly and push this phase hard because it’s the bottleneck, not the construction itself.
3. Foundation and utility trenching (Weeks 7-9)
With permits in hand, we stake the footprint, trench for electrical and plumbing laterals, and pour the foundation. Underground rough-in happens now, and the slab gets a termite pretreatment and vapor barrier before concrete goes down. If your lot elevation requires a raised stem wall, this is when we build it. The foundation inspection happens before we backfill or set any form boards.
4. Shell construction, roofing, and exterior envelope (Weeks 10-14)
Framing, roof trusses or rafters, sheathing, and the roofer go up in tight sequence. Stucco and exterior trim follow. Window and door installation includes only impact-rated units labeled for the High-Velocity Hurricane Zone, a non-negotiable requirement here. The rough framing, shear-wall nailing, and window-anchoring all get inspected before insulation and drywall start. Expect a mid-point inspection by the county and possibly an ARB drive-by to confirm the shell matches the approved elevations.
5. Interior finishes, MEP trim-out, and final inspections (Weeks 15-22)
Drywall, paint, flooring, cabinetry, countertops, and Verona Walk Small Bathroom Remodels fixture trim-out fill these final weeks. The plumber sets fixtures, the electrician installs devices and the subpanel, and the HVAC tech commissions the mini-split or ducted system. Final electrical, plumbing, and building inspections happen here, plus a floodplain administrator’s final if your FEMA zone requires it. When the last sign-off posts and the ARB issues the completion letter, the unit is yours to use.
The decisions that shape your new detached ADU
- Foundation type: slab-on-grade vs. raised stem wall. Slab is the lower-cost option on lots already above the base flood elevation. A raised stem wall adds $8,000 to $15,000 but is mandatory if the county says your finished floor needs to come up. We’ll only know after reading your elevation certificate.
- Exterior finish: stucco to match your main house vs. fiber-cement lap siding. Stucco blends seamlessly with Verona Walk’s existing architecture and passes ARB review with zero friction, though it costs more per square foot. Fiber-cement lap siding from James Hardie holds up beautifully in coastal humidity but may require additional ARB justification if the community guidelines favor stucco-only exteriors.
- Roofing: hip tile to match the original DiVosta roof vs. standing-seam metal. A tile roof matches what’s already on your house and sails through ARB approval. Standing-seam metal is lighter, faster to install, and performs exceptionally in hurricane conditions, but you’ll need to show the ARB color and profile samples that complement the existing streetscape.
- Kitchenette scope: wet bar vs. full cooking kitchen. A wet bar with a sink, undercounter fridge, and microwave costs significantly less than running a gas line or 50-amp range circuit. A full kitchen adds real long-term value if you plan to rent the unit someday, and we coordinate rough-in placement early so you don’t close walls on a regretted half-measure.
- Climate control: ductless mini-split vs. small central ducted system. A mini-split handles cooling and heating for a studio or one-bedroom ADU efficiently and costs less to install. A ducted system distributes air more evenly across multiple rooms but requires attic or soffit space that eats into your ceiling height or square footage.
What a new detached ADU costs in Verona Walk, FL
A new detached ADU in Verona Walk runs $45,000 on the low end for a simple studio with a wet bar and basic finishes, up to about $130,000 for a larger one-bedroom unit with our Small & Partial Kitchen Remodels service in Verona Walk and higher-end fixtures, and a raised foundation on a flood-zone lot. Most homeowners land between $90,000 and $120,000.
Five things push your number toward the high or low end:
- Square footage and layout. A 400-square-foot studio costs less than half of an 800-square-foot one-bedroom, all else equal. Every extra foot of foundation, framing, roofing, and finish material adds cost linearly.
- Foundation elevation requirements. If your FEMA zone demands a raised floor, the stem wall, fill, and extra stair landing add real money. A slab-on-grade lot avoids this entirely.
- Utility extension distance. Trenching a new electrical lateral and water line 30 feet from the main house is one thing. Trenching 100 feet across a landscaped yard past a paver patio is another, and it shows up in the excavation and restoration line items.
- Interior finish level. Stock cabinetry and laminate counters keep the budget low. Custom cabinets and a quartz or solid-surface counter move the number up fast. Flooring, tile, and plumbing fixtures follow the same pattern.
- ARB-required exterior upgrades. If the HOA asks for a specific roof tile profile, decorative shutters, or upgraded landscaping to screen the unit, those go into the budget before we even start framing. We identify these during ARB submittal so they never surprise you mid-build.
Our written estimate separates every one of these line items so you see exactly what you’re paying for. No allowances that drift, no buried change orders. If it’s not in the estimate, it’s not in the price. Call (844) 638-7249 to schedule a free, no-pressure on-site estimate and we’ll give you a real number for your property.
What Verona Walk homes specifically do to this job
Verona Walk is a DiVosta Homes community built largely between 2004 and 2009, and nearly every residence uses the builder’s poured-concrete wall system instead of standard CMU block. That matters for a detached ADU in two ways. First, the main house itself has no hollow cores to fish new electrical or plumbing through if you decide to tie the ADU’s utilities to the existing panel or water line at the house wall. Any penetration through a concrete exterior wall requires a core drill and diamond blade, which changes the labor math on tie-in scope relative to a block home. Second, the community’s mandatory HOA architectural review adds a formal approval gate before Collier County even accepts your permit application. We submit exterior elevations, roof style, window specs, finish colors, and drainage plans to the ARB and often get back requests for tile-profile matching, stucco-color consistency, or landscaping sight-line screening. It adds 3 to 5 weeks to the front end but keeps you out of violation letters later. In a neighborhood where every home shares a common architectural DNA, getting the ARB approval clean the first time is the difference between a project that moves steadily and one that stalls before it starts.

Frequently asked, new detached ADU in Verona Walk
Yes. Every detached ADU requires a Collier County building permit plus Verona Walk HOA architectural review approval. No homeowner is exempt, and building without both approvals can result in fines, lien filings, and a stop-work order that forces you to remove unpermitted work at your own expense. We handle the entire application sequence: ARB submittal first, county permit second.
Plan on 18 to 28 weeks total. The HOA architectural review and county permit review typically take 6 to 10 weeks by themselves. Physical construction runs another 12 to 18 weeks depending on foundation type, utility distance, and the interior finish package you choose. We give you a week-by-week schedule before we break ground so you know when your inspections land and when the unit is ready to occupy.
Yes, and we recommend it. A new detached ADU typically gets its own water lateral from the street main and its own sewer lateral to the existing septic or sewer tap, so we aren’t cutting open your main house slab or core-drilling through poured-concrete walls to tie in. Running independent underground lines is faster, less disruptive, and actually simplifies the plumbing inspection since the ADU’s system stands alone.
