Mildew in Indian Rocks Beach homes can be everyday bathroom and closet growth from salt-air humidity, or the first visible sign of walls that stayed wet after surge, high tide or a rain backup. Surface spots on tile and glass are a homeowner job; growth on drywall that took water needs more than cleaning.

Is this just humidity, or did water get in?
Indian Rocks Beach is a low-lying Gulf beach city, with average ground elevation of about 5 to 6 feet, set between the Gulf, the Narrows and Clearwater Harbor. The city points out three ways water gets into homes: storm surge, a high tide pushed by a west wind, and heavy rain that fills the drainage system and backs water up into houses. Mildew along the bottom few inches of a wall, on the back of baseboards or under area rugs usually means one of those happened, even briefly. Mildew on a bathroom ceiling, a closet wall or a sliding-door track is more often humid air with nowhere to go. The first kind calls for opening the wall; the second is a cleaning and ventilation job.
What did Helene change?
Helene's surge came ashore overnight in 2024 at up to 8 feet on the Pinellas barrier islands, AP reported. Residents here said earlier surges had stayed about knee-high, and people who stayed in their homes died in the flooding. The city notes that its shallow, gently sloping Gulf bottom can produce higher surge than a storm's category suggests. In homes that took that water, EPA's rule applies: if materials couldn't be dried within 24 to 48 hours, assume mold growth and remove soaked drywall, insulation and carpet rather than wiping them down.
Do I need approval to rebuild after cleanup?
Yes, if cleanup turns into a remodel. The entire city is a FEMA Special Flood Hazard Area, and all floodplain development needs a permit. Interior remodels, such as replacing drywall after water damage, first need city zoning and flood approval, which is then submitted with a Pinellas County Building Services permit application. Substantial improvements, at 50 percent or more of the building's pre-work market value, must meet new-construction standards. Cleaning surface mildew doesn't need a permit.

A local note
The city's Planning, Zoning and Permitting Department also administers code enforcement, so renters with an unfixed leak can call City Hall on Bay Palm Boulevard. Standard homeowner policies usually don't cover flood, so photograph flood-related damage before anything is thrown out.
