Members from the Palm Terrace Co-ops in Ontario, CA welcomed law enforcement during National Night Out which is an annual community-building campaign that strengthens the bond between law enforcement and the neighborhoods they serve. It’s all about fostering safer, more connected communities through partnership, trust, and engagement.

Held on the first Tuesday in August, National Night Out brings together millions of neighbors across all 50 states, U.S. territories, and military bases around the world. Communities celebrate with block parties, festivals, parades, cookouts, and a variety of family-friendly events that include safety demonstrations, youth activities, emergency personnel visits, and more.

On August 4, 2026, we were honored to welcome Congressman Dave Min to Mariposa Villa in Irvine, CA!

Congressman Min began his visit with a tour of our community, followed by a meet-and-greet and engaging Q & A session with more than 20 resident-members in the community room. He took time to speak one-on-one with several of them and hear directly about their experiences and concerns.

Our discussions included CSI’s mission and the services we provide, the growing need for additional affordable housing, the important role of service coordination in supporting members, and the recent interior renovations at Mariposa Villa. Congressman Min demonstrated a strong understanding of HUD, the challenges facing affordable senior housing, and the urgent need for more affordable housing opportunities.

A special thank you to our service coordinator Adriana and the members who generously donated and served cookies, croissants, bagels, coffee, and other refreshments. Your hospitality helped make the visit especially welcoming.

We appreciate Congressman Min taking the time to visit Mariposa Villa, connect with our members, and learn more about the work being done to support affordable senior housing in our community.

Our development manager James Downing is featured in an excellent article by Ben Phillips on different kinds of social housing across America:

“Our board of directors is composed of residents who are elected by their peers,” he says. “As one might expect, they place a high priority on protecting and improving their homes. Our board consistently guides us toward slow, deliberate growth and cautious use of debt.”

Our co-op management style is a rather unique approach in affordable housing for seniors, but not only does it work; it also gives our 7,000 members the opportunity to thrive, learn and grow with the people living right next to them.

Over the past several years, Social Housing has become a much-discussed housing trend. Now, industry experts assess the movement.
