Why Ocala houses move
The rock under Ocala has the city's own name. The Ocala Limestone was first described here in 1892. It sits at or near the surface across this part of Florida. It is also part of the Floridan Aquifer, the water supply under your feet.
Limestone like this dissolves slowly in rainwater. Over time, gaps form in the rock. The sand on top can wash down into those gaps. When that happens under part of a house, that part settles.
Marion County's own aquifer study rates the land west of Silver Springs as "most vulnerable" and "more vulnerable," the Ocala Gazette reported in June 2026. The state geology office says sinkholes are most active when heavy rain follows a drought. A dry spring and a wet summer is the pattern to watch.
