OK, here's an incentive UBI pilot program in Denver.

Denver's universal basic income project reports early success

Now, the $50/mo group is a joke.  This pays your cell phone bill.

The other 2 programs are slightly more realistic, but neither is enough by itself just to rent a 1 bedroom apartment in the Denver market, much less cover all the rest of your basic costs for living like food, transportation and communication.  So you're homeless hard case you're trying to help bootstrap himself up still needs a job, but even a $15/hr min wage job should be enough supplemented by the UBI.

One would expect that staying eligible for your monthly UBI check requires staying clean and not getting in trouble with the cops, but thats gonna take frequent visits by a social worker at the least.  The real question is assuming your hard case can clean up enough to actually get a job like say stacking shelves in a warehouse, will he be able to keep it for more than a week?  Show up on time for his shifts, not get in fights with other workers, do what the boss says without mouthing off, resist the temptation to steal some merchandise, not call in sick more than once or twice a month etc?  The social skills said person has acquired to survive living on the street are not generally the same ones needed in the workplace.

Anyhow, the UBI is at least some attempt to save these lost souls, but the cost of expanding it beyond a pilot program would be high, because after all not only the hard cases need the UBI, so does every other worker in the warehouse.  The rednecks who work there and are not ex-junkies would not be pleased if they didn't get the free money also.
