But not everyone is willing or able to conform to the rules required for such housing. Further, people migrate to SF and join the homeless population faster than people are housed.

There's conditions required for any housing, including housing one owns.

I do not think the requirements that SF allows its housing partners to impose are excessive (don't destroy the housing; don't deal drugs from the housing; don't continually create noise/waste/smells that adversely impact your neighbors).

SF also requires that nuisance evictions be conducted with plenty of warning and efforts by landlords and caseworkers to cure.. e.g.

> Nuisance evictions should include numerous incident reports, tenant complaints, prompt writeups and a “last ditch” tenant conference meeting with notes or a signed agreement.

And said tenants are entitled to due process after these numerous writeups and conference meetings, and legal assistance.
