More part-year homes than the county around it
Seasonal, recreational or occasional use accounts for 4,723 of Venice's 20,966 housing units, about 22.5%, against 15.1% across Sarasota County. The Census counts these homes as vacant. Its full 2020 count found much the same, at 21.8%.
Those are counts of homes kept for part-year use, not counts of rodents. In practice they mean many owners need a plan for the months a house or condo stays shut, and the city's Chapter 88 upkeep standards apply whether the home is occupied or not.
