ADU Rules in Fort Myers, Florida
We've researched Fort Myers's ADU rules so you don't have to. Here's what matters most — the facts that determine whether your project is possible, and how much it will cost.
- No owner-occupancy requirement — investor-friendly in the Lee County market
- Lee County jurisdiction for unincorporated areas; City of Fort Myers for incorporated — verify your address jurisdiction
- NOT in HVHZ — Lee County uses Wind Borne Debris Region standards, less restrictive than Miami-Dade/Broward; saves 15–20% on costs
- Hurricane Ian (Sept 2022) caused significant damage — post-Ian rebuild has increased contractor costs and demand in Lee County
- Short-term rental market strong (Fort Myers Beach proximity, Edison Festival tourism); Lee County STR registration required
- Construction $100,000–$195,000; rental income $1,000–$1,800/month LTR; higher near Fort Myers Beach and Cape Coral access

Fort Myers ADU — Frequently Asked Questions
These are the questions we hear most often from Fort Myers homeowners. If yours isn't here, our ADU Zoning Experts can answer it directly.
How did Hurricane Ian affect ADU construction in Fort Myers?
Hurricane Ian (September 2022) was devastating for Lee County. Many Fort Myers properties sustained significant structural damage and required rebuilding under updated codes. Post-Ian effects include: FEMA flood map revisions increasing Zone AE designations, contractor shortages and elevated material costs, longer permit wait times due to rebuild volume, and updated base flood elevation requirements on many parcels. Verify your flood zone status before any ADU planning.
How do I know if my Fort Myers address is City or unincorporated Lee County?
This matters because the permit office is different. Look up your parcel at the Lee County Property Appraiser (leepa.org) — the jurisdiction field will show 'City of Fort Myers' or 'Lee County.' City of Fort Myers properties permit through the City Building Division (239-321-7925). Unincorporated Lee County properties permit through Lee County Building (239-533-8585).
Is Fort Myers a good market for short-term rental ADU income?
Fort Myers has a solid STR market driven by winter snowbird tourism, proximity to Fort Myers Beach (significantly rebuilt post-Ian), and the Edison-Ford Winter Estates museum tourism. Lee County requires Tourist Development Tax (TDT) registration for all STRs. Year-round LTR income of $1,000–$1,800/month is more reliable than STR in this market's current rebuild phase.
What flood zone changes should I be aware of post-Ian for Fort Myers ADU planning?
FEMA updated flood insurance rate maps for Lee County after Hurricane Ian. Many properties that were previously in Zone X (minimal flood risk) may have been reclassified to Zone AE (high flood risk). A Zone AE reclassification requires elevated construction and a flood elevation certificate, adding cost. Check the current FEMA map at msc.fema.gov using your exact parcel address.
Are contractor costs still elevated in Fort Myers post-Ian?
Yes. As of March 2026, the post-Ian rebuild continues to affect contractor availability and pricing in Lee County. Construction costs for a Fort Myers ADU ($100,000–$195,000) remain elevated compared to pre-Ian levels, driven by labor shortages and material demand from the ongoing rebuild. Get 3+ bids and expect longer lead times for project starts than in unaffected Florida markets.
