Building permits, zoning and septic rules in Lee County, Florida

Unincorporated Lee County requires a permit for construction, enlargement, alteration, repair, movement, demolition and occupancy changes; limited exceptions are identified in the applicable building and land-development codes¹. Applications and plans must meet the Florida Building Code, 8th Edition (2023), subject to those exceptions¹. The issued permit identifies required inspections, which applicants request through eConnect or the automated inspection system; the permit, approved plans and manufacturers' specifications must be onsite⁶. Residential owner-builders in unincorporated Lee County must submit an Owner-Builder Declaration of Self-Use or Owner-Builder Disclosure Statement; building permits remain required⁶. If private-provider plan review is used, Lee County also requires private-provider inspections¹. A nonresidential farm building on land used for bona fide agriculture may qualify for a code and fee exemption, but the exemption does not cover a residence or floodplain-management rules¹¹.

Lee County Community Development runs Building and Permitting Services for unincorporated Lee County; the office is at 1500 Monroe St., Fort Myers, FL 33901, and its phone is 239-533-8585². Inside Fort Myers, the city handles building permits, with temporary-housing building permits required after activation of a housing emergency¹². Sanibel also handles its own building permits, with limited exemptions for minor residential work¹³. Septic permits stay with the Florida Department of Health in Lee County rather than the city or county building department³. Zoning questions go to Community Development at 239-533-8329 or occszoning@leegov.com⁴. Flood questions go to the department's flood line at 239-533-8948². Lee County publishes building-permit, plan-review and reinspection fee schedules, and permits also carry administration and radon fees, so use the current schedule for a project estimate¹⁴. A residential driveway in a county-maintained right-of-way needs a separate right-of-way permit, listed at $95 for a single driveway and $120 for a double driveway on buildings of one to four units¹⁵.

Lee County zoning and land-development rules apply to unincorporated land⁴. Fort Myers, Bonita Springs, Estero, Sanibel and Fort Myers Beach have their own zoning rules^{16,17,18,19,20}. Septic permitting stays with the Florida Department of Health in Lee County³.

For unincorporated Lee County parcels, use the linked zoning maps and Land Development Code to identify district standards; the county zoning webpage does not reproduce the full district list or all district rules⁴. Lot dimensions, setbacks and coverage vary by district or lot type; planned developments and special exceptions can modify setbacks²¹. One county-wide setback exception: an exterior stairway to a dwelling entrance may encroach up to 3 feet into a side setback or 8 feet into a front setback, subject to public-safety review²². Height limits vary by land-use category and special area; for example, the Outlying Suburban category at South Seas Resort caps height at 45 feet, and 75 feet requires a zoning action showing the extra height is needed to preserve environmentally sensitive land, habitat, or historic, archaeological or scenic resources²². In flood-prone areas, height is measured from the minimum required flood elevation²². An older single-family attached-district ordinance specifies 600 square feet per unit; confirm applicability under the current code with Community Development zoning before choosing a plan^4,23.

Florida DEP implements the statewide septic rules, while the Florida Department of Health in Lee County continues local OSTDS permitting and inspections³. A septic permit is required for a new system, and new applications in unincorporated Lee County must be designed by a Florida-licensed professional engineer⁵. The application fee is $390; a site evaluation, outer-island inspection or performance-based treatment may add fees, while basin-management and sewer-availability conditions may add requirements⁵. The system must pass inspection, and an owner or authorized contractor may hire a private provider for that inspection while the department retains final review^3,24. Contact Environmental Health at 239-690-2100 or leeeh@flhealth.gov, at 2295 Victoria Ave. Ste. 206, Fort Myers, FL 33901²⁵.

We could not confirm a Lee County rule allowing full-time RV living, temporary camping or tiny-home occupancy on an ordinary private parcel. Florida's permit for an RV park or recreational camp covers transient accommodation in a regulated park or camp and does not establish permission on private land elsewhere⁷. Ask Community Development zoning whether the parcel's district permits the proposed unit and occupancy before buying or moving one onsite⁴. Lee County identifies detached accessory apartments as a Residential New Primary Structure permit category, subject to zoning and building-code requirements; that category does not establish blanket tiny-home approval⁶. A manufactured home has a clearer route: an off-site-constructed dwelling treated as real property must be permitted as of right in a district allowing detached single-family homes, but generally applicable permitting, health, utility, design and setback requirements still apply⁸. A compliant manufactured-home installation also requires an onsite inspection before a certificate of occupancy issues²⁶.

1. Confirm whether the parcel is in unincorporated Lee County or an incorporated municipality, because the responsible permitting office changes at the city line².
2. Check the parcel's zoning district, allowed use, lot dimensions, setbacks, coverage and height with Community Development^4,21,22.
3. For a subdivision, obtain a Development Order before site work or building-permit issuance^4,27.
4. If the site uses septic, obtain the new-system permit through the Florida Department of Health in Lee County^5,25.
5. Confirm legal access: spacing depends on road classification, and a residential lot with another access option may not connect directly to an arterial or collector road²⁸.
6. Complete building-permit review, request required inspections and satisfy final occupancy conditions⁶. For a site governed by a Development Order, Development Services must issue a Certificate of Compliance before approved use, including issuance of a building Certificate of Occupancy²⁷.

Check jurisdiction first because county zoning and permitting apply only in unincorporated Lee County². Lee County Utilities serves only its service area and does not serve several named municipalities and communities; final occupancy requires sewer inspection or septic approval, plus well approval when a well is used⁶. No mapped soils are rated “not limited” for a conventional septic drain field; that does not make septic impossible, but makes site evaluation and system design essential^5,29. Check road classification and access options before assuming a driveway location will be approved²⁸. Qualifying work in a regulatory floodway requires an engineer-sealed No-Rise or No-Impact Certification approved by the Floodplain Administrator, while Special Flood Hazard Area rules can affect renovations, additions and elevation certificates⁶. A private well requires a permit⁹; the Lee County Permit Center lists well construction permits under Natural Resources¹⁰.
