Do you need a building permit in unincorporated 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 exceptions1415. 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 onsite16. Residential owner-builders in unincorporated Lee County must submit an Owner-Builder Declaration of Self-Use or Owner-Builder Disclosure Statement; building permits remain required9. If private-provider plan review is used, Lee County also requires private-provider inspections17. 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 rules18.
Who issues building permits in Lee County, and how do you reach them?
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 239-533-85853. Inside Fort Myers, the city handles building permits, with temporary-housing building permits required after activation of a housing emergency19. Sanibel also handles its own building permits, with limited exemptions for minor residential work20. Septic permits stay with the Florida Department of Health in Lee County rather than the city or county building department7. Zoning questions go to Community Development at 239-533-8329 or occszoning@leegov.com21. Flood questions go to the department's flood line at 239-533-89483. 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 estimate22. 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 units23.
Does Lee County have zoning?
Lee County zoning and land-development rules apply to unincorporated land24. Fort Myers, Bonita Springs, Estero, Sanibel and Fort Myers Beach have their own zoning rules2526272829. Septic permitting stays with the Florida Department of Health in Lee County4.
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 rules3031. Lot dimensions, setbacks and coverage vary by district or lot type; planned developments and special exceptions can modify setbacks323334. 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 review35. 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 resources36. In flood-prone areas, height is measured from the minimum required flood elevation37. 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 plan3821.
Who issues septic (OSTDS) permits in Lee County?
Florida DEP implements the statewide septic rules, while the Florida Department of Health in Lee County continues local OSTDS permitting and inspections397. A septic permit is required for a new system, and new applications in unincorporated Lee County must be designed by a Florida-licensed professional engineer640. 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 requirements6. The system must pass inspection, and an owner or authorized contractor may hire a private provider for that inspection while the department retains final review841. Contact Environmental Health at 239-690-2100 or leeeh@flhealth.gov, at 2295 Victoria Ave. Ste. 206, Fort Myers, FL 3390142.
Can you live in an RV or tiny home on your land in Lee County?
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 elsewhere1043. Ask Community Development zoning whether the parcel's district permits the proposed unit and occupancy before buying or moving one onsite2124. 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 approval44. 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 apply11. A compliant manufactured-home installation also requires an onsite inspection before a certificate of occupancy issues45.
What are the steps to build a home in Lee County?
- Confirm whether the parcel is in unincorporated Lee County or an incorporated municipality, because the responsible permitting office changes at the city line2.
- Check the parcel's zoning district, allowed use, lot dimensions, setbacks, coverage and height with Community Development303233344621.
- For a subdivision, obtain a Development Order before site work or building-permit issuance4748.
- If the site uses septic, obtain the new-system permit through the Florida Department of Health in Lee County642.
- 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 road49.
- Complete building-permit review, request required inspections and satisfy final occupancy conditions501651. 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 Occupancy52.
What should you check before buying land in Lee County?
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 used53. 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 essential546. Check road classification and access options before assuming a driveway location will be approved49. 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 certificates55. A private well requires a permit12; the Lee County Permit Center lists well construction permits under Natural Resources13.
Watch-outs
- County building and zoning rules apply in unincorporated Lee County; incorporated municipalities administer their own jurisdictions2.
- Florida's recreational-vehicle-park and camp permits (Chapter 513) cover stays in a licensed park, not whether you can live in an RV on your own unincorporated land; that's a zoning question, not settled here1021.
- Repairs and renovations in unincorporated Lee County Special Flood Hazard Areas require building permits; qualifying regulatory-floodway work also requires an engineer-sealed certification approved by the Floodplain Administrator5655.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
