What ADU Design & Permitting Actually Takes in Tice, FL - and What It Costs
Designing and permitting a new accessory dwelling unit in Tice, FL typically runs $45,000-$130,000 and takes four to seven months from the first site measure to the day we lock up the shell. That timeline is not a guess. It accounts for the real bottleneck in unincorporated Lee County right now: post-Ian permit queues that demand pre-scheduled inspections the moment we submit drawings. Call us at (844) 638-7249 and we’ll walk you through what your specific lot can yield - the estimate is free and there’s zero pressure.
A well-executed ADU design in Tice is less about the square footage you draw than about how early you engage the county’s wind-load and flood-plain review triggers. Older Tice lots, especially those near Orange River Boulevard or east of Ortiz Avenue, sit on flat, high-water-table ground where slab elevation and drainage become permitting variables before you even pick a floor plan. We have worked through enough of these to know which site conditions will add cost and which are handled with a standard engineered foundation. That upfront clarity is what prevents a $95,000 budget from becoming a $140,000 surprise.
How We Move an ADU in Tice From a Sketch to a Signed Permit
Every ADU project we run in Tice follows five concrete stages. The homeowner decisions happen at predictable points, not in panicked phone calls halfway through rough-in. Here is how it actually works.
Site Survey & Feasibility Walk
Duration: 1-2 weeks. We measure the lot, locate the existing septic or sewer lateral, map overhead utilities, and take soil elevations relative to the base flood elevation for your FEMA panel. In Tice, where the water table sits high and standing stormwater is common after afternoon thunderstorms, this stage tells us whether we need engineered fill, a raised slab, or additional drainage swales before the county will sign off. You decide: detached vs. attached, approximate square footage, and whether the unit needs a full kitchen - that answer alone swings the plumbing and mechanical scope enough to shift the permit path.
Architectural & Structural Drawings
Duration: 3-5 weeks. Our draftsman produces floor plans, elevations, and roof-framing details that meet current Florida Building Code requirements - not the code that was in place when your 1960s CBS house was built. We size roof straps, specify impact-rated windows or approved shutters, and detail shear-wall continuity from the bottom plate to the truss. Because Tice is unincorporated, every page gets scrutinized by a county plan reviewer who will flag missing wind-load calcs or incomplete opening-protection schedules. We include those on the first submission, not the third resubmission. You decide: window placement, door swing, closet layout, and exterior finish material.
Permit Submission & County Review
Duration: 4-8 weeks. This is the stage where out-of-area contractors lose their margins. Lee County’s building department in Fort Myers handles all Tice permits, and post-Ian backlogs mean review times stretch longer than pre-storm norms. We pre-schedule rough-in and framing inspections at the time of submittal - a tactic that shaves two to four weeks off the post-approval timeline because we are not sitting idle waiting on an inspector while the slab is ready to pour. You decide: nothing, honestly. This is our fight. We push the package through and call you the day it clears.
Pre-Construction Buyout & Material Lock
Duration: 1-2 weeks. The permit is in hand. Now we write the final material schedule: truss package, windows, exterior doors, siding or stucco, roofing underlayment, and interior finish categories like flooring and cabinetry. We lock supplier pricing so your number does not drift during the build. This is also when we confirm the electrical service size - many Tice homes still run 100-amp panels, and adding a full ADU with a minisplit, electric range, and laundry typically requires a service upgrade to 200 amps, which we pull as a separate permit. You decide: material grades, finish colors, appliance package level.
Foundation, Shell & Dry-In
Duration: 6-10 weeks. We form and pour the slab, stand the walls, set the trusses, sheath the roof, dry it in with underlayment, and hang the windows and exterior doors. In Tice’s humidity, we do not leave OSB exposed overnight without a weather barrier - moisture intrusion during shell stage is the single biggest source of mold problems we see when we open up walls on botched jobs. Our crews are background-checked, uniformed, and they show up in a marked vehicle. You get photos at every inspection pass and a walkthrough before insulation goes in.
Once the shell is locked, the interior trades roll - plumbing top-out, electrical rough-in, HVAC, insulation, drywall, trim, paint, flooring, and fixture set. From permit approval to final, most Tice ADUs are move-in ready in another twelve to sixteen weeks. The entire process, from the day you call to the day you hand a tenant the keys, lands right around five to seven months when the county reviews move at their current pace.
The Spec Choices That Shape Your ADU Cost in Tice
Two homeowners building the same 600-square-foot ADU can spend $90,000 apart based on the spec decisions below. Here are the options you will actually sit down and choose between, with the honest trade-offs of each.
- Foundation type: slab-on-grade vs. raised stem wall. Slab-on-grade is standard for Tice lots and keeps costs down, but if your property sits in a low spot that ponds water after storms - common east of I-75 in the older county pockets - a raised stem wall adds $8,000-$14,000 and eliminates the flood-risk mitigation conversations with the county reviewer.
- Wall assembly: standard wood frame vs. reinforced CMU. Most detached ADUs we build in Tice are wood-frame on a concrete slab, which matches the existing house profile and passes wind-load review with engineered hold-downs. Upgrading to reinforced CMU block adds roughly $15-$22 per square foot and buys you higher wind-debris impact resistance, which some homeowners on exposed lots near the Caloosahatchee prefer.
- Roof system: asphalt shingle vs. standing-seam metal. Architectural shingles from GAF or CertainTeed handle Florida wind uplift when installed over a fully sealed deck and are the most common spec. Standing-seam metal runs $8,000-$14,000 more on a typical ADU roof but carries a longer service life and lower wind-peel risk, a real consideration after what Tice saw in Ian.
- Cladding: fiber-cement lap vs. stucco finish. James Hardie lap siding holds paint longer and handles Tice humidity better than wood composite. A three-coat stucco finish over frame is typically a few thousand less but requires more maintenance on the south-facing exposure, where the sun eats the elastomeric coating faster than manufacturers admit.
- Kitchen level: wet-bar only vs. full range kitchen. A wet bar with a microwave, undercounter fridge, and sink keeps the plumbing simple and the electrical demand low. A full kitchen with a range, dishwasher, and garbage disposal triggers a heavier electrical load calc, a dedicated 40-amp circuit, and often a panel upgrade - adding $6,000-$10,000 to the total once the electrical scope is fully accounted for.
None of these choices are right or wrong. They are just math. We lay out the numbers in a written line-item estimate so you can decide which trade-offs make sense for your property, your budget, and how you plan to use the unit. Our pricing is upfront and fixed once the scope is locked - the number you see is the number you pay.
What ADU Design & Permitting Costs in Tice, FL
A new detached ADU in Tice runs $45,000 on the very low end - think a 400-square-foot efficiency with a wet bar, basic finishes, and a simple lot - and reaches $130,000 for an 800-square-foot one-bedroom with a full kitchen, midrange finishes, impact-rated openings throughout, and more involved site work. The four variables that push a project toward the high end are consistent across nearly every job we price here.
Square footage is the obvious one: materials and labor scale with the footprint, and every extra 100 square feet adds roughly $15,000-$22,000 depending on finish level. Site conditions are the wildcard specific to Tice - lots with poor drainage, dense clay near the surface, or a high water table can require engineered fill, raised slabs, and additional stormwater mitigation that pads the site-work line item by $5,000-$12,000. Electrical service capacity trips up a lot of budgets: if your existing 100-amp panel cannot carry the ADU load, upgrading to 200 amps adds $3,500-$5,500 and its own separate permit. Finish level is the choice that swings the widest - builder-grade cabinets and laminate counters keep the interior tight; custom KraftMaid cabinetry and quartz or Cambria surfaces can add $14,000-$22,000 to the fit-out cost without changing a single wall.
Our written estimate breaks out every line item - site work, foundation, shell, MEP trades, insulation and drywall, interior finishes, and the permit fees Lee County charges at submittal. The permit fees themselves are a hard cost we pass through at exact cost, typically $2,800-$5,500 for a residential ADU depending on valuation and impact-fee schedule. Nothing is buried and nothing gets billed as a change order unless you change the scope. Call (844) 638-7249 and we will price your ADU honestly, with the real county-imposed costs included on day one.
What Tice Homes Specifically Do to an ADU Project
Tice’s older concrete-block homes, most built between the 1950s and the mid-1970s, were framed long before modern wind-load strapping requirements existed. When you pull a permit for an attached or detached ADU on a Tice lot, the county does not review just the new structure - the reviewer checks whether the electrical service upgrade, the tie-in to the existing structure, or any shared roofline trigger a compliance review on the original house. We have seen straightforward garage-conversion ADUs turn into multi-trade projects the moment the reviewer flags the legacy single-pane jalousie windows or the unstrapped wood trusses on the main home.
That is not a reason to avoid building in Tice. It is a reason to price the permit scope accurately from the start and to work with a contractor who knows Lee County’s plan-review patterns. Our team has navigated enough Tice submittals to know which trigger points to anticipate and pre-engineer into the drawings - hurricane straps, impact-rated openings, and a roof-deck nailing pattern that meets current code - so the review comments come back as a short list, not a rewrite. Tice’s post-Ian reality is that building back better is not a slogan here; it is what the county enforces. We build to that standard on every job, whether the reviewer asks for it or not.
Drainage and slab prep also look different in Tice than they do a mile south in a master-planned Fort Myers subdivision. The high seasonal water table and flat grade mean that a simple monolithic slab pour requires more crushed-stone base and perimeter drain detail than a comparable lot in a community with engineered stormwater retention. We account for that in site-work pricing and we pull the appropriate NOC and grading permits alongside the building package so nothing stalls mid-dig. This is the kind of local scheduling and soil knowledge that keeps a Tice ADU on track when an out-of-area builder would still be waiting on a revised drainage letter.
When homeowners in Tice are also planning a larger whole-home renovation, we often coordinate the ADU build as part of a full Home Additions & ADU in Tice project so the permits, crews, and inspections run under one integrated schedule. If the main house needs a kitchen overhaul alongside the ADU, our Full Kitchen Remodeling in Tice crew can sequence that work once the shell is dry. And when the ADU is going in near the main home’s existing outdoor hardscape, we regularly pair it with Cabinets & Countertops in Tice upgrades that bring both spaces to the same finish level.
Our Home Additions & ADU team works across Tice and the surrounding Lee County communities, bringing the same 730-Day Done Right Promise to every project - if it’s not done right, we make it right, in writing, for two full years.

Frequently Asked Questions About ADU Design & Permitting in Tice
In unincorporated Lee County, where Tice permits route through the Fort Myers building department, you should budget four to eight weeks for county review alone after drawings are submitted. Design and engineering add another four to six weeks, and construction typically runs four to five months from slab pour to final. The full timeline, first call to move-in, is five to seven months in the current post-Ian permitting environment. We pre-schedule inspections at submittal to cut out the dead weeks that inflate that number for other builders. Call (844) 638-7249 and we’ll give you a timeline tied to your specific scope, not a generic estimate.
Yes. Every ADU in Tice - attached, detached, garage conversion, or interior carve-out - requires a building permit from Lee County, and the plans must meet current Florida Building Code requirements including wind-load, impact-protection, and flood-plain provisions even if the main house predates those standards. We handle the full permit package, from engineered drawings to NOC recording, and we pull all trade permits as part of the scope. No one from your family needs to stand at a county counter.
Sometimes, and this is one of the cost variables we nail down during the feasibility walk. If your existing septic system is sized to handle the additional bedroom load and the drain field is not in the footprint of the new structure, we can often tie in without relocating anything. If the system is undersized or the county health department flags the location, you are looking at a new septic design or a sewer lateral extension, which adds $6,000-$15,000. We tell you which bucket you fall into after the first site visit, before any design dollars are spent.
A 400-square-foot efficiency with basic finishes, a wet bar, and a straightforward slab-on-grade foundation starts around $45,000-$55,000 in Tice. An 800-square-foot one-bedroom with a full kitchen, mid-to-upper-tier cabinetry, quartz counters, impact-rated windows, and a standing-seam metal roof runs $110,000-$130,000. The biggest individual cost swings come from kitchen spec level, electrical service upgrades, site drainage work, and exterior cladding choice. We provide a free written estimate that breaks out every line item so you can see exactly where your money goes.
Every ADU we design, permit, and build in Tice is covered by the 730-Day Done Right Promise - if it’s not done right, we make it right, in writing, for two full years.
