When young adults leave the parental nest, they often follow a predictable pattern. First, move in with roommates. Then graduate to a single or couple’s pad. After that comes the big purchase of a single-family home. A lawnmower might be next.

Looking at the new home construction industry, one would have good reason to presume those norms were holding steady. About two-thirds of new homes being built in the U.S. this year are single-family dwellings, complete with tidy yards and plentiful parking.

In startup-land, however, the presumptions about where housing demand is going looks a bit different. Home sharing is on the rise, along with more temporary lease options, high-touch service and smaller spaces in sought-after urban locations.

Seeking roommates and venture capital

A Crunchbase News analysis of residential-focused real estate startups uncovered a raft of companies with a shared and temporary housing focus that have raised funding in the past year or so.

This isn’t a U.S.-specific phenomenon. Funded shared and short-term housing startups are cropping up across the globe, from China to Europe to Southeast Asia. For this article, however, we’ll focus on U.S. startups. In the chart below, we feature several that have raised recent rounds.

Notice any commonalities? Yes, the startups listed are all based in either New York or the San Francisco Bay Area, two metropolises associated with scarce, pricey housing. But while these two metro areas offer the bulk of startups’ living spaces, they’re also operating in other cities, including Los Angeles, Seattle and Pittsburgh.

From white picket fences to high-rise partitions

The early developers of the U.S. suburban planned communities of the 1950s and 60s weren’t just selling houses. They were selling a vision of the American Dream, complete with quarter-acre lawns, dishwashers and spacious garages.

By the same token, today’s shared housing startups are selling another vision. It’s not just about renting a room; it’s also about being part of a community, making friends and exploring a new city.
