A century of river humidity behind downtown's walls
Fort Myers grew up on the Caloosahatchee after Captain Manuel A. Gonzalez's 1866 settlement and the town's mid-1880s incorporation, and Thomas Edison's arrival in 1885 — building his winter estate, Seminole Lodge, and honeymooning there in 1886 — helped draw the wave of riverfront construction that followed. More than a century of wood-frame building and additions in the River District has had just as long to trap moisture behind walls never built with modern vapor barriers.
Why Ian's downtown flooding still matters for older buildings
In September 2022, Hurricane Ian's storm surge reversed the Caloosahatchee's flow and pushed the river over its banks, filling downtown buildings on Bay and First streets with four to six feet of water. A mold assessment on a River District property built well before that event should check for both century-old construction gaps and any water Ian left trapped behind a wall that looked dry on the outside.

What to share about a Fort Myers property
Note the building's approximate age, any Hurricane Ian flood history near Bay or First streets, and where growth or a musty smell is showing up. Provider availability varies, and homeowners should verify credentials directly.
Downtown's humidity baseline
Southwest Florida holds roughly 70–75% average relative humidity year-round, well above the 60% level where mold risk climbs, and a riverfront building compounds that with direct exposure to the Caloosahatchee. Confirm the property's flood zone and base flood elevation as part of any remediation plan.
