Brandon Dill, 31, had his eye set on Silverwood before the Southern California development had houses to show. The community, set in the Inland Empire about 80 miles east of Los Angeles, promised affordable homes in one of the country's most expensive states to live, events to bring neighbors together and access to beautiful parks and trails.

Dill convinced his wife, Cathy Khoonsrivong, to look at the development as they prepared to be first-time parents. She approved, and Dill signed them up.

One document in their new housing paperwork gave them pause: A "Kindness Pledge."

"That's interesting," Khoonsrivong remembers thinking.

The pledge said Silverwood is "creating a place that feels familiar, like the small towns our parents and grandparents grew up enjoying."
