With a recent heatwave and coronavirus closing public pools, some Californians are flexing their entrepreneurial muscles.

A start-up company called Swimply lets people who own pools rent them out by the hour.

One couple in Los Angeles tells local news station KTLA that they have made nearly $7000 by allowing strangers to come to their home to use the swimming pool.

As of Sunday, 165 pools were listed.

Some were described as “kid-friendly” and others were “resort-like.” The running rental rates were from $30 to $75 dollars an hour.
