Lee County (#4) and Collier County (#9) both rank in the top ten counties in the U.S. for number of residences designated as second or vacation homes.

The U.S. has about 7.4 million vacation and second homes, or about 5.6 percent of the total housing stock, according to a recent National Association of Home Builders (NAHB) analysis of 2016 national census data.

Florida has the largest stock of second homes – 1.1 million properties – followed by California, New York, Texas, Michigan, North Carolina, Arizona and Pennsylvania.

“The concentration of second homes is not simply restricted to conventional locations like beachfront areas,” NAHB reports in its Eye on Housing blog. Second homes account for at least 10 percent of the local housing stock in about 916 counties in 49 states. Connecticut and Washington, D.C., were the two exceptions.

The counties with the most second homes tend to be located in or near metro areas. The following 10 counties, half of which are in Florida, have the most second homes:

  1. Maricopa County, Ariz.: 113,513 second homes
  2. Palm Beach County, Fla.: 99,536
  3. Broward County, Fla.: 97,224
  4. Lee County, Fla.: 95,671
  5. Miami-Dade County, Fla.: 87,225
  6. Riverside County, Calif.: 76,331
  7. Pinellas County, Fla.: 65,281
  8. Barnstable County, Mass.: 63,225
  9. Collier County, Fla.: 61,050
  10. Suffolk County, N.Y.: 58,452
