How to raise rent for Section 8 tenants in compliance with lease stated $100 each additional against arbitary jurisdiction for OHA's $20 each?

Order to Mandate is the form to force agency to comply with the law but
how to make sure this work?

addition tenant should not be govened by agency in Section 8 ?

This is a tactic of theirs. They also like to tie rent increases to the cost of
  living index (which will give a whopping 2.9% increase). Here's what you need
to  do:
1. Find out what census tract your property is in. Sec8 bases
everything  on the 4 digit tract number. Go
  to:
http://factfinder.census.gov/servlet/AGSGeoAddressServlet?_lang=en&_programYear=50&_treeId=420
2. put in your address & it will show the census tract number. Then click
  'Map It' & it will show your census area- this is the area where you must
  base your comp's. Print a copy of the map & keep on file.
3. Contact a Realtor & have them do a wildcard rental search for this map
  area- go back several years if necessary. You will be surprised how many rental
  comp's are in the MLS. I've been a realtor for 12 years & I had no idea!
4. Send the comp's to Sec8 as proof of comparable rents & fight for the
  increase.
Your odds are much better with this approach because it shows you know what
  you're doing & you'll have solid evidence to make your case.
