"An important ruling has been issued by the Massachusetts Federal Court that has big waves in the residential management community - many of the commonplace "fees" charged to Tenants and Prospects are now unlawful.

At least that way, the jerk will have an eviction on all future eviction reports, by having an unlawful detainer/eviction filing in his name.  

Unlawfully withholding a security deposit will result in having to return 3 the deposit if you go to court in this state, not sure about where your friend is.

The Act makes it unlawful to refuse to make reasonable accommodations to rules, policies, practices, or services when such accommodations may be necessary to afford persons with disabilities an equal opportunity to use and enjoy a dwelling.

AAMOF based on legislation in other jurisdictions the legality of the sort of late fee clauses most have in their leases is highly questionable.In the UK for example  http://www.propertylawuk.net/residentialucta.html the following is cited as an unfair termimpose potentially excessive penalties on tenants for failure to meet the terms of the contract e.g. by charging excessive rates of interest on late payments of rentI like the chances of the tenant that argues that  the late fee should be construed as interest and that the 5% a month many landlords have in their leases is unlawfully usurious (multiply that by 4 if they were only a week late). 

And there's no better place to flee from those pesky housing initiatives than the home state of this guy http://en.wikipedia.org/wiki/Julian_Castro (take a look at  his job title) and  no better city than Fort Worth http://www.star-telegram.com/news/local/community/...Your baldfaced refusal to accept vouchers is probably unlawful of itself but even if I am wrong on that it is not hard to construe such a policy  as discriminatory on grounds of, sex, race and/or familial status as those demographics will be disproportionately disadvantaged by your exclusion.Everybody thinks they are fair.

@Michael Meeks If I knew your tenants I'd tell them that your charges are unlawful and your late fee clause  is unenforceable.

THE BOARD'S FINDING THAT APPELLANT ENGAGED IN UNLAWFUL HOUSING DISCRIMINATION IS CLEARLY AGAINST THE WEIGHT OF EVIDENCE.

. "** "...in addition to any other action which it may take under this section, award the petitioner damages, which damages shall include, but shall not be limited to, the expense incurred by the petitioner for obtaining alternative housing or space, for storage of goods and effects, for moving and for other costs actually incurred by him as a result of such unlawful practice or violation."*** "ad•judge(əˈdʒʌdʒ) v.t.

This to be an incentive to leave the place clean and undamaged.And explain that if you file an unlawful detainer (or whatever the eviction proceeding is where you are), that will go on a database that will show on eviction reports that future landlords will pull - even if they win the eviction proceeding.
