How it works

From idea to certificate of occupancy

ADUs involve zoning review, architectural drawings, engineering, multiple permit departments, and a final CO inspection. We manage the entire process under one contract — you don't project-manage it.

01

Feasibility & vision

We review your lot, zoning, setbacks, utility connections, and HOA restrictions before you spend a dollar on drawings. We tell you what's buildable before anyone gets excited about floor plans.

02

Design & permit

Architectural drawings, structural engineering, and permit submission. We manage the back-and-forth with the Building Division, Zoning, and any required HOA approvals. Permit fees included in written scope.

03

Construction

Foundation, framing, roofing, electrical, plumbing, insulation, drywall, flooring, kitchen or kitchenette, bathroom — all trades coordinated under our GC license.

04

CO & handoff

Final inspections across all trades, CO issued by the county. You receive a completed, legal dwelling unit with a certificate of occupancy — ready to rent or move family in.

What we build in Lee County

ADU types — from garage conversion to detached build

Garage conversions are the fastest and most cost-effective ADU option in Lee County. Detached ADUs on large lots offer more flexibility and rental income potential. We build both.

Garage conversion

Convert your existing attached or detached garage into a legal, permitted living space. We handle the floor leveling, insulation upgrade, mini-split HVAC, electrical panel sub-feed, plumbing rough-in for a kitchenette and bathroom, and CO application. Most efficient ADU path in Lee County.

Attached or detachedKitchenetteFull bathroomMini-splitCO included

Detached ADU

A standalone dwelling unit built on your lot — separate from the main house. New foundation, full mechanical systems, its own utility connections, kitchen, bathroom, and CO. Best option for maximizing rental income or creating a fully independent living space for family.

Lee County · What property owners need to know

Why ADU permitting in Lee County requires a licensed GC

ADU projects in Lee County touch every trade and every permit department. The process takes months and requires coordination that a handyman or unlicensed contractor simply cannot legally perform.

Multiple Permit Types Required

An ADU typically requires a building permit, electrical permit, plumbing permit, and mechanical permit — all submitted and managed separately. Under a licensed GC permit, we pull all of these under one contract. The county inspects each trade separately. Without a GC managing this, homeowners end up coordinating 4+ separate contractor permits and inspections — and the CO doesn't issue until all of them close.

Zoning & Setback Rules Vary by City

ADU regulations in Lee County vary significantly between unincorporated county land, Fort Myers, Cape Coral, Bonita Springs, Estero, and other municipalities. Minimum lot size, setbacks, max square footage, and utility connection requirements are all different. We research the specific rules for your parcel before we quote — not after you've already paid for drawings that don't meet code.

HOA Restrictions

Many Lee County communities — especially in Cape Coral's canal-front neighborhoods and gated Estero and Bonita Springs developments — have restrictions on ADU construction, including setbacks from property lines, exterior materials, roofline requirements, and sometimes outright prohibitions. We review your HOA or condo association documents and CC&Rs before any money is spent on design. Building without approval is a covenant violation with real legal exposure.

Utility Connection Complexity

Detached ADUs require electrical service (new sub-panel or meter), water connection, and sewer tap. In Lee County, sewer tap fees alone can run $3,000–$12,000 depending on municipality, and some areas of Lehigh Acres and unincorporated Lee still rely on septic — which changes the scope entirely. We include a utility connection cost assessment in the written scope — not a rough estimate. You know what it costs before you sign anything.

The CO is What Matters

The certificate of occupancy is what makes an ADU legal to rent or occupy. Unpermitted "in-law suites" have no legal standing and create serious liability when you sell or insure the property. Every ADU we build targets a CO at close-out. The permit timeline is managed by us, and we don't consider a project finished until the CO is in your hands.

One Contract, Soup to Nuts

We provide architectural drawings, manage the permit, coordinate all trades, and deliver the CO. You have one contract and one point of contact — not a separate architect, engineer, plumber, electrician, and framer you hired off Craigslist. That's the value of a design-build licensed GC for a project this complex, now available across Lee County.

What ADU builders navigate in Lee County

We bring the same feasibility-first ADU process we built in South Florida to Lee County. Here is what shapes every project in this county.

Zoning by Jurisdiction

  • Lee County unincorporated: ADUs allowed on qualifying lots with appropriate zoning
  • City of Fort Myers: ADU ordinance with specific design and setback standards
  • City of Cape Coral: ADUs permitted; canal-lot setbacks add another layer of review
  • Bonita Springs and Estero: each run separate application processes through city planning
  • Lehigh Acres: unincorporated, often on septic — confirm utility capacity before designing

Typical Timeline

  • Feasibility + zoning review: 1–2 weeks
  • Architectural drawings + engineering: 4–8 weeks
  • Permit submission and review: 4–12 weeks (varies by jurisdiction)
  • Construction — garage conversion: 8–14 weeks
  • Construction — detached ADU: 16–28 weeks
  • Final inspections + CO: 1–3 weeks after construction complete

Cost Variables to Know

  • Sewer tap fees: $3,000–$12,000 depending on municipality (or septic install if unincorporated)
  • Impact fees: $5,000–$18,000 for new detached ADU in Lee County
  • Architectural drawings: $4,000–$12,000 (included in our scope)
  • Structural engineering: $2,000–$6,000 (included in our scope)
  • Permit fees: $1,500–$6,000 (included in our scope)

Common Use Cases

  • Rental income unit — single-family neighborhoods in Cape Coral and Lehigh Acres
  • In-law or family suite — Fort Myers and Estero primary homes
  • Short-term rental / investment ADU — common near Fort Myers Beach and Bonita Springs
  • Home office + guest space combo — Estero and newer Fort Myers communities

The most common reason an ADU project stalls in Lee County is a zoning or association issue discovered after the homeowner has already paid for drawings. We spend the first 1–2 weeks on feasibility — lot coverage, setbacks, minimum lot size, utility capacity, and HOA or condo association review — before anyone draws a line. That's not extra overhead; it's the difference between a project that happens and one that dies after $15,000 in sunk design costs.

Impact fees and utility connection costs are the other surprise that low estimates omit. A detached ADU in Lee County can trigger $8,000–$18,000 in impact fees and $4,000–$12,000 in sewer tap fees — or a septic system if you're in unincorporated Lehigh Acres — costs that have nothing to do with construction and everything to do with municipal infrastructure. We identify every fee in writing before you sign, whether the project is in Cape Coral or Estero. No surprises at permit issuance.

Verified reviews from ADU and garage conversion projects across Southwest Florida.

★★★★★

"Dariceli told us upfront that our HOA would need to approve before any drawings were started. We got approval first, then permitted, then built. CO in hand 7 months after we first called. The process was exactly what she described."

"Garage conversion in Cape Coral. D&Co handled the drawings, the permit, all the trades, and the CO. My mother moved in within 4 months. The biggest thing was knowing the full cost upfront — no surprises on impact fees or utility hookups."

★★★★★

"I rent the unit out to seasonal tenants near Fort Myers Beach. The total project cost was $81,000. I had two other contractors tell me they 'couldn't guarantee a CO.' D&Co was the only one who built it into the contract. That mattered more than the price."
