California recently started a Universal Basic Income Program (UBI) but, it is too early to tell if it will actually help reduce homelessness or instead cause a concentration of the US homeless population to migrate to California.

This article is from July[2022] and it has a more global review of UBI type programs that have been tried in the past or are currently in progress(Kenya for example).

California is trialing a guaranteed basic income, which is very different from a UBI. The latter is universal, while a GBI is conditional. Conditional money grants gated on income invariably create high marginal tax rates, as a dollar can result in no net increase in take home income.
