Question about somebody taking advantage of free housing?

I know somebody who is taking advantage of a free housing apartment complex. These apartments offer apartments free or reduced rent, depending on your income. The typical tenants are elderly people or young families. This person is a 23 year old male with no problems other than laziness. He is purposely not working so that he can obtain free rent. (They also pay your utilities if you have 0 income). He refuses to look for a job, instead just sitting around all day. He's been living here for 2 years, originally getting the apartment with his disabled mother but she chose to leave when the original lease expired.

Now though, an apartment opened up near me that he is interested in. There's a job close by he's wanting to apply for but its about an hour away from his current place. He has the plan to move into the new place but continue to keep the free place in case it doesn't work out.

I'm just so sickened by this. His apartment could be used to actually help people in need, not provoke laziness. Is there anything I can do?
