Florida land feasibility is driven by flood elevation, wetlands, and septic approval far more than by slope. Counties administer zoning while the Department of Health approves onsite sewage systems, so a lot can be legally zoned for a house and still fail on soils.
County seat: Jacksonville
Duval County is consolidated with the City of Jacksonville, so nearly every parcel is reviewed by one planning department. Infill lots in Northside and Westside neighborhoods are the most common land-investing targets, and many were platted decades before the current ordinance.
County seat: Bartow
Polk County sits between Tampa and Orlando and is one of Florida's most active land markets. Rural residential and agricultural tracts dominate outside the incorporated cities.
County seat: Ocala
Marion County is a high-volume market for cheap rural lots, including many legacy paper subdivisions such as those in the Ocala/Marion Oaks area.
County seat: Tavares
Lake County's mix of citrus-legacy acreage and lakefront residential lots draws both builders and lot flippers northwest of Orlando.
