11:27 AM PT -- Jon and Lisa joined us on "TMZ Live" Thursday and told us why they wanted to help address the homelessness crisis facing L.A. and the rest of the country.
The couple says the tiny home communities are much faster, easier and more practical to build than affordable housing, and they tell us why the communities are serving people in greater ways than just providing shelter.
Jon Cryer and Lisa Joyner are joining forces with a non-profit doing all it can to tackle the homeless crisis in Los Angeles ... by providing tiny homes for shelter.
The "Two and a Half Men" star and his wife are spearheading a fundraising effort with the Hope of the Valley Rescue Mission, which opened the first Tiny Home Village in North Hollywood last month.
Along with donating $30,000 to the org's ongoing mission to fight homelessness and poverty in the L.A. area, Jon and Lisa will also be running 2 miles of the 125-MILE ultra-marathon to raise money for the cause.
Hope of the Valley hopes to raise over $200k, which will go toward opening another 500-bed Tiny Home Community across the San Fernando Valley.
Jon and Lisa will also serve as Tiny Home Village sponsors. A rep for HOTV also tells us it’s important to note that city councilman Paul Kerkorian, made it possible to build these homes in the city.
According to Hope of the Valley, the Tiny Homes initiative is an "innovative, affordable, and scalable solution to the humanitarian crisis known as homelessness" ... and with Jon and Lisa's support, it's ramping up in the best way.
