What ADU Site Prep & Utilities in Tice Actually Costs and How Long It Takes
ADU site prep and utilities in Tice typically runs between $45,000 and $130,000, with most projects taking 4 to 8 weeks to complete the ground-work phase before framing begins. That number covers clearing/grading, foundation work, trenching, and running new water, sewer, and electrical service from the street or main panel to the ADU footprint.

How We Handle ADU Site Prep & Utilities in Tice - The Real Sequence
Stage 1: Site Survey & Utility Locate (Days 1-3)
Before dirt moves, we flag every existing line. Florida 811 marks public utilities free of charge, but on older Tice lots we also hand-sweep with a private locator because 1950s-1970s homes often have undocumented irrigation lines, abandoned septic laterals, or homeowner-run electrical buried without conduit. You’ll decide early whether we’re tying into the existing septic system (if your Tice property isn’t on county sewer) or running new laterals - that single decision can swing the budget by $8,000-$15,000.
Stage 2: Clearing, Demolition & Rough Grading (Days 3-7)
We strip the ADU footprint of vegetation, remove any old concrete pads or sheds, and rough-grade for positive drainage. Tice sits in a high-water-table zone where standing water after rain is common, so we over-excavate by 6-10 inches and backfill with compacted shell or crushed stone before forming the slab - skip that step and you’ll get slab cracks within two wet seasons. If the site requires tree removal or major root clearing, this stage extends by 2-3 days and adds permitting steps through Lee County.
Stage 3: Foundation & Slab Prep (Days 7-14)
Form boards go up, vapor barrier goes down, rebar or wire mesh is tied per the engineered drawings. Lee County inspectors must sign off on the formwork and reinforcing before any concrete is poured - and post-Ian inspection queues in Tice are still running 5-10 business days out, so we pre-schedule this inspection at permit application to avoid dead time. Once the slab is poured and cured (3-5 days minimum before framing loads), we move to underground rough-ins.
Stage 4: Trenching & Underground Utilities (Days 14-28)
This is where the heavy digging happens. We trench from the main house panel to the ADU for a new subpanel feeder, from the water meter or main line for domestic supply, and from the nearest sewer lateral or septic tank for waste. Tice’s sandy loam soils trench fast but collapse easily - every trench deeper than four feet gets shored or stepped back per OSHA, which adds labor hours but is non-negotiable for safety. If we’re hitting coral rock or buried construction debris (common on older Tice parcels), the trenching timeline stretches and your budget moves toward the higher end of the range.
Stage 5: Backfill, Rough Inspections & Site Finish (Days 28-35)
Once underground plumbing and conduit are in, Lee County inspects the trench and rough-ins. After passing, we backfill in lifts, compact mechanically, and do final grading around the slab to direct water away. The last step before framing is stubbing out water, sewer, and electrical connections above the slab for the framing and MEP crews. At this point the site prep is complete and your ADU project - part of a full Home Additions & ADU in Tice - moves into vertical construction.
The Options You’ll Choose Between During ADU Site Prep
- Monolithic slab vs. stem-wall foundation. A monolithic pour is faster and cheaper ($6-$10 per square foot) and works well on Tice’s flat lots with good drainage. A stem wall raises the finished floor 18-24 inches above grade - better flood protection in a high-water-table area, but adds $8-$15 per square foot and requires more concrete and masonry labor.
- Septic tie-in vs. dedicated system. If your Tice home is on septic and the existing tank has capacity, we can tie the ADU into it and save you $5,000-$10,000. If the tank is undersized or failing (common in 1960s-era systems with steel tanks), you’ll need a new dedicated system or a replacement, which pushes the utility cost toward the upper end of the range.
- Direct-bury vs. conduit-protected electrical feeder. Code allows direct-bury aluminum feeder cable, but we recommend running it inside schedule 40 PVC conduit - it adds about $3-$5 per linear foot but protects against the inevitable shovel strike or ground shift during Tice’s wet-dry cycles. Conduit also makes future upgrades possible without re-trenching.
- Standard vs. hurricane-impact site-prep measures. Tice’s post-Ian reality means any ADU foundation must meet current Florida Building Code wind-load anchoring standards - but you can opt for upgraded Simpson Strong-Tie anchors and thicker slab-edge steel that exceed code minimums. It’s a few hundred dollars extra and worth it if you’re building a structure your family sleeps in.
- Gravel drive vs. paved access for construction. During site work we need a stable access path for concrete trucks and material deliveries. A temporary compacted shell access runs $1,200-$2,500 depending on distance from the street. If you’re already planning a permanent driveway as part of a wider project, our home additions & ADU crew can coordinate that pour alongside the slab to save mobilization costs.
What ADU Site Prep & Utilities Costs in Tice, FL
Count on $45,000-$130,000 for the full site-prep and utility scope on a detached ADU in Tice. The low end covers a straightforward backyard site with close utility access, sandy soil with no obstructions, and a simple monolithic slab. The high end reflects properties requiring long trench runs from the street, septic system replacement, extensive tree/root removal, or soil stabilization in persistently wet areas.
Four things push the number: distance from existing utilities - every linear foot of trench adds labor, shoring, and conduit cost; soil conditions - hitting coral rock or old buried debris turns a two-day trench into a week’s work; septic vs. sewer - tying to county sewer where available is cheaper than a new septic field, but many Tice streets still lack sewer infrastructure; permit and impact-fee scope - Lee County assesses utility connection fees and ADU impact fees that can range from $3,000 to $12,000 depending on meter size and district, and those are separate line items in your estimate.
Our written estimate includes: site survey and utility locate, clearing and rough grading, foundation excavation and slab, all trenching and underground rough-ins, backfill and compaction, final grade, and the permit coordination. It does not include Lee County impact fees or separate electrical service upgrades to the main house, which we price transparently if needed. You’ll see every line broken out - no vague allowances, no change-order games. Upfront pricing with no surprises is how we’ve earned trust across Tice and the surrounding Lee County communities.
What Tice Homes Specifically Do to This Job
Site prep in Tice is different because the housing stock is different. Nearly every property we work on here was built between the 1950s and 1970s - modest concrete-block homes on lots that predate modern Florida Building Code. When you pull a permit for an ADU in unincorporated Lee County, the county reviews the entire scope against current code, and they’ll frequently flag the main house’s electrical service, existing septic load, or foundation setbacks. That means what starts as “just trench and pour a slab” often becomes a coordinated multi-trade job that includes a panel upgrade or a septic assessment before the ADU foundation passes inspection.
The post-Ian reality adds another layer: county building inspectors in Fort Myers are still working through backlogs, and inspection windows for underground and slab work can stretch 5-10 business days unless the slot is reserved the moment the permit number is issued. We pre-schedule every inspection at permit application - it’s a small procedural move that keeps your job from stalling mid-phase, and it’s the kind of thing contractors who don’t work Tice regularly get wrong. Homeowners often pair this ground-up work with interior upgrades to the main house, and our crews also handle Small & Partial Kitchen Remodels in Tice and Full Bathroom Remodeling in Tice - it’s common to sequence the ADU site prep first, then tackle the main house’s kitchen or bath while the ADU goes vertical.

Frequently Asked - ADU Site Prep & Utilities in Tice
Four to eight weeks, with the biggest variable being Lee County inspection scheduling. The physical work - clearing, grading, slab, trenching, backfill - takes about three to four weeks. The rest is cure time on concrete, waiting for utility-locate responses, and lining up county inspectors. Pre-scheduling inspections at permit issuance keeps the back end of the timeline predictable; without that step, add two to three weeks.
Yes - every component requires a Lee County building permit. This includes a site-development permit for grading and drainage, a foundation permit with engineered drawings, and separate electrical/plumbing permits for trenching and underground rough-ins. Because Tice is unincorporated Lee County, all permits run through the county building department in Fort Myers, not a municipal office. We handle the full permit package for you.
Rarely - and when you can, it’s because the ADU footprint happens to sit directly adjacent to the main house’s panel and water main. In most Tice backyards, you’re looking at trench distances of 40 to 120 feet from existing utilities, which means a new subpanel feeder, a dedicated water line, and a new sewer lateral or septic connection. There’s no shortcut here; the county requires independent shutoffs and dedicated service runs for a legal secondary dwelling unit.
Four things: hitting coral rock or buried debris during excavation, which adds days of hammering and removal; septic system issues - many original 1960s tanks are too small for an added dwelling and must be replaced; long utility trench runs from the street if the ADU is set far back on a deep lot; and unplanned main-panel upgrades when the existing service can’t handle an ADU subpanel. Each of these can move a $55,000 site-prep budget toward $90,000 fast. We walk through every one of these variables during the estimate so you’re not surprised.
