A new analysis by Brian Potter of Construction Physics, recently highlighted by data analyst Santi Ruiz, reveals that approximately 1.2 million vacation homes in the United States are situated within five kilometers of the ocean. The comprehensive mapping project identifies census tracts where vacation homes constitute 20% or more of the total housing units, offering a granular view of seasonal housing concentrations across the nation.
The detailed map illustrates significant clusters of vacation properties in coastal Florida, throughout New England, across parts of the upper Midwest, and in specific Western states. While coastal areas, particularly along the East and Gulf Coasts, show extensive lines of seasonal homes, the West Coast, despite its length, exhibits fewer such concentrations. Florida alone, with a coastline 1.5 to 2.5 times that of California, accounts for around 5.6 times as many ocean-adjacent vacation homes.
Santi Ruiz, a data analyst known for sharing insights on urbanism and housing, brought attention to Potter's work, stating in his tweet, "Here's vacation homes by census tract (h/t @_brianpotter ofc)." This collaboration underscores the increasing public interest in understanding housing market dynamics at a local level. Brian Potter's Construction Physics newsletter frequently delves into the intricacies of construction and housing trends.
The growing concentration of vacation homes in desirable areas is increasingly linked to challenges in local housing markets. As properties are purchased or converted for seasonal use, the supply of housing available for year-round residents often diminishes. This trend can lead to significant increases in housing costs, making it difficult for essential workers and long-term community members to afford to live in these areas.
Experts suggest that the proliferation of vacation homes can alter the social and economic fabric of communities, potentially displacing local populations and changing the character of neighborhoods. Some regions are exploring policy measures, such as increased property taxes on second homes or restrictions on short-term rentals, to mitigate these impacts and foster more balanced housing ecosystems.
