What a New Detached ADU in Tice Actually Takes - Scope, Timeline, and Cost
A new detached ADU in Tice typically runs between $90,000 and $220,000 and takes 4 to 7 months from permit submission to final inspection. You’re building a fully independent living unit on your property, a backyard home with its own kitchen, bathroom, bedroom, and utilities, all built to current Florida Building Code. The spread in cost depends heavily on whether you go with a prefab system like Abodu or a full custom stick-built unit, and how much site prep your specific Tice lot needs. Call (844) 638-7249 to talk through what your property can support, and we’ll give you a real number, not a blind range.
How a New Detached ADU Comes Together in Tice
Site survey and utility mapping (days 1-7)
We start by pulling a full property survey and locating existing underground utilities, sewer laterals, and the water main. In Tice, where lot sizes vary widely and many homes still run on original cast-iron sewer lines from the 1960s, this step either confirms a straightforward tap or surfaces a line replacement you’ll need to budget for. You decide early whether to extend from the house’s panel or install a separate meter, and that choice alone can swing costs by $2,500 to $6,000 depending on LCEC requirements and trench distance.
Permitting and plan review with Lee County (weeks 1-6)
Because Tice is unincorporated Lee County, every permit flows through the building department in Fort Myers. Post-Ian backlogs are real, and we pre-schedule inspections the day we submit plans to keep the job moving. This phase covers architectural drawings, structural engineering calcs, wind-load certifications, and impact-product approvals. If your existing home predates the 2002 Florida Building Code, the permit review often flags required tie-down upgrades on the main house, and we handle that coordination so one project doesn’t derail the other. This is also when you lock in floor plan, roof pitch, window packages, and interior finish level.
Foundation, slab, and underground rough-ins (weeks 7-9)
Tice sits in a high-water-table zone where standing water after a heavy rain is common. Our first step on the build site is grading for positive drainage and, on many lots, bringing in Quikrete or Sakrete bagged concrete for footers and stem walls if the soil conditions require a deepened perimeter beam. We trench and lay the sewer lateral, water line, and electrical conduit, then pour a monolithic slab with vapor barrier underneath. County inspection happens before we pour; we don’t pour until it passes. At this stage you’ll see the unit’s footprint for the first time, and it’s the last easy moment to tweak door or window placement before framing begins.
Framing, sheathing, and roof assembly (weeks 10-13)
Walls go up, roof trusses get set, and the structure gets sheathed and dried in. For Tice, every exterior opening gets impact-rated windows or shutters, and the roof assembly includes secondary water barrier and ring-shank nails at tightened spacing to meet current wind-uplift requirements. If you’ve chosen a prefab manufacturer like Abodu, this stage compresses to roughly two weeks of panel-setting and structural tie-in work, but site-built framing gives you more flexibility on ceiling height, window sizes, and roofline. We rough in plumbing, electrical, and HVAC ductwork inside the wall cavities before insulation goes in.
Interior finishes, trim, and final inspections (weeks 14-20)
Insulation, drywall, flooring, cabinetry, countertops, fixtures, appliances, and paint happen in this stretch. This is the most visible part of the project and the one where your upfront decisions show up in the real space. We schedule the final building, electrical, plumbing, and mechanical inspections with Lee County and walk the unit with you before sign-off. From foundation dig to final CO, we’ve done this long enough to know that a clean inspection record and a punch list completed before handover make the difference between a job you’re relieved is over and one you’d call us back for on the next project, which, if we’re being honest, is the only kind of job worth doing.
The Choices That Define Your New Detached ADU in Tice
Every detached ADU starts with the same set of decisions. The options you pick here drive the price more than any single line item. Here’s what you’ll choose between, with the real trade-offs spelled out.
- Stick-built versus prefab. A custom stick-built unit gives you total control over dimensions, roofline, window placement, and materials, but adds 8 to 12 weeks of framing and drying-in time. A prefab like Abodu arrives as pre-built modules set by crane. It’s faster and factory-precise, but you trade some layout flexibility for speed. Both paths meet Florida code; the right call depends on your timeline and how specific your floor plan needs are.
- Foundation type. On Tice lots with good drainage, a standard monolithic slab on grade works well and costs less. On lots where water pools after a storm, we often recommend raising the slab 8 to 12 inches above grade with fill and a deepened footing, adding $4,000 to $9,000 but protecting the structure long-term. Crawlspace options exist but are uncommon locally due to humidity and pest exposure.
- Kitchen and bathroom finish level. Cabinetry, countertops, tile, and plumbing fixtures run a huge range. A simple kitchen with stock cabinets and laminate counters keeps the budget lean; quartz or solid-surface tops with KraftMaid cabinets push the number higher. The same split applies to the bathroom: a fiberglass tub-shower unit versus a tiled walk-in with glass enclosure.
- HVAC strategy. A mini-split system handles heating and cooling efficiently in a unit up to roughly 800 square feet, with no ductwork needed and lower install cost. For a larger ADU or one you plan to rent as a true apartment, a full ducted system with its own air handler gives better air distribution and filtration, but adds $6,000 to $10,000.
- Utility connections. Tapping into the existing house’s electrical panel saves money if the panel has capacity and the trench run is short. A separate meter and new service drop from LCEC gives the tenant their own bill and independence, but costs more up front. Sewer is the wildcard: some Tice homes still feed old clay or cast-iron laterals that won’t pass a Lee County pressure test, and a new lateral from the ADU to the street tap can add $7,000 to $14,000 overnight.
What a New Detached ADU Costs in Tice, FL
A new detached ADU in Tice lands between $90,000 and $220,000. A compact studio with a simple kitchen and bathroom on a flat lot with easy utility access starts near the low end. A two-bedroom unit with a full custom kitchen, tiled bath, separate HVAC system, and a new sewer lateral pushes toward the top of the range. The gap isn’t margin padding - it’s scope.
The four big variables: unit square footage (a 400-square-foot studio costs less to frame, roof, insulate, and finish than a 1,000-square-foot one-bedroom), site conditions (high water table requiring a raised slab or extra fill, plus the condition of your existing sewer and electrical service), finish level (stock cabinets and laminate tops hold the budget; custom millwork and stone surfaces don’t), and the utility connection path (tapping the existing panel versus a new meter, and whether the sewer lateral passes inspection).
Every estimate we write in Tice includes a line-by-line scope of work with material quantities and allowances, a fixed price, and a payment schedule tied to completed phases - never to calendar dates. What’s typically excluded: impact fees Lee County may assess, any upgrades you choose mid-build, and repairs to the main house that the permit triggers but aren’t part of the ADU build. When a full Home Additions & ADU in Tice project touches the primary structure simultaneously, we coordinate the scopes so you’re not paying twice for mobilization.
What Tice Homes Do to a Detached ADU Timeline and Scope
Tice isn’t a master-planned subdivision with uniform lot dimensions, predictable soil, and homes built last Tuesday. Most properties here are modest concrete block homes from the 1950s through the 1970s, and nearly every one we work on carries some combination of pre-2002 wind-load detailing, original cast-iron or clay sewer laterals, and single-pane jalousie windows long overdue for replacement. The ADU permit process with Lee County in Fort Myers routinely triggers a full Florida Building Code review of the main house’s roof-to-wall connections, and we’ve lost count of how many times a straightforward backyard unit turned into a concurrent reroof with hurricane straps, impact-rated openings, and reinforced decking - not because we upsold it, but because the county reviewer flagged it on the plan check and wouldn’t sign off otherwise.
Post-Ian inspection backlogs are a local scheduling reality here in Tice that no amount of project-management software solves. We pre-schedule every inspection at the moment of permit application, and we still build a two-week buffer into the timeline because the county’s inspector corps is stretched thin. The high water table and standing-water tendencies on low-lying lots mean we evaluate drainage and slab elevation on the first site visit - not as a checkbox, but as a go/no-go variable that changes the foundation design and the real cost before the first shovel breaks ground. These aren’t obstacles unique to your property; they’re just the way construction works in an unincorporated Lee County community that took Ian’s eyewall and has been rebuilding ever since. Homeowners who also want interior finish work often pair the ADU build with Backsplash, Tile & Flooring in Tice so the same crew handles both scopes without another round of scheduling.

Frequently Asked - New Detached ADU in Tice
Four to seven months from the day we submit plans to Lee County through final inspection sign-off. The permitting phase - plan review, engineering stamps, and county backlogs - accounts for the first 4 to 6 weeks. Construction typically runs 14 to 20 weeks, depending on whether you choose a custom stick-built unit or a prefab system like Abodu that compresses framing and drying-in. Wet-season months can add a week or two for foundation work on low-lying Tice lots. Call (844) 638-7249 and we’ll map a schedule specific to your property and scope.
Yes. Every detached ADU in unincorporated Lee County requires building, electrical, plumbing, and mechanical permits, plus a zoning clearance confirming the unit meets setback, lot-coverage, and height requirements for your specific Tice parcel. We handle the full permit package as part of the project - drawings, structural calcs, product approvals, the works - and we don’t start digging until the permit card is posted.
That depends on what the plan reviewer finds when they examine your existing utility connections and structural details. On a Tice lot where the sewer lateral is newer PVC and has capacity, the ADU ties in cleanly. On a property where the original cast-iron lateral fails a pressure test or the main panel doesn’t have room for a subfeed breaker, you’ll be doing that work whether you planned for it or not. We flag these risks during the site survey so you’re never surprised mid-build. Homeowners who want to rework the main house’s layout at the same time often bring the ADU build under a wider Home Additions & ADU plan so one crew sequences everything.
The price includes the complete ADU: site prep and foundation, framing or prefab module set, roofing, siding, insulation, drywall, paint, flooring, a full kitchen and bathroom, electrical, plumbing, HVAC, impact-rated windows and exterior doors, and all permit and inspection fees. The low end reflects a compact studio with simple finishes, a mini-split system, and straightforward utility connections. The high end reflects a larger unit with custom cabinetry, stone or quartz counters, a ducted HVAC system, a separate electric meter, and the kind of site-prep surprises - raised slab, new sewer lateral - that older Tice parcels sometimes demand. Some homeowners coordinating a broader remodel also bring in Kitchen Design & Layout in Tice to ensure the ADU’s kitchen matches the design standard of the main house.
Every ADU we build is covered by our 730-Day Done Right Promise. If something isn’t right, we make it right - two full years, no fine print carve-outs, no arguing over whether a crack is settlement or poor workmanship. Manufacturer warranties on windows, roofing, appliances, and mechanical systems apply on top of our workmanship guarantee, and we document every one of them in your closeout packet. The number you see on the upfront estimate is the number you pay - we don’t come back mid-job asking for a change order because we forgot to budget for a permit fee or underestimated the window package.
