How often floodwater reaches Greenville homes

In Greenville County, 0.6% of homes carry federal flood insurance, while 6.1% do across South Carolina. The gap makes sense on paper. FEMA's National Risk Index puts Greenville's yearly hurricane loss at $3 per $100,000 of building value, against 97 for the state, so coastal storms drive the statewide numbers.

Inland flooding is another matter. The same index puts the city's yearly inland flood loss at $73, above the state's 67, with the county at 86. FEMA flood insurance records show 1.5 claims per 1,000 homes from 2016 to 2025, a little above the county's 1.2, and the average building payment on a city claim was $25,791. Greenville County has had 9 major disaster declarations for floods and storms since 2000 and logged 11 days with flash flood or flood reports from 2016 to 2025. By NOAA climate normals, the city sees about 14 days a year with an inch of rain or more.

Rain that runs into a home from outside is Category 3, because it carries soil, runoff and sometimes sewage. Standard homeowners and renters policies exclude it, and only flood insurance covers it. With 59% of homes rented, many residents in the Greenville area need their own contents coverage before a storm. The restoration crew treats any floor that storm water touched as contaminated, and the same steps apply to water removal in Mauldin.
