Jessica Riley, spokeswoman for the state Office of Mental Health, said she could not comment on the lawsuit. She said the state invests nearly $500 million annually for community-based housing for adults with serious mental illness, including more than 44,000 units of housing statewide. Riley said the state has a commitment to develop at least 6,000 units by 2021, with 120 of these new units targeted to individuals being released from prison.
