It's all part of the Crime-Free Multi-Housing Program, which started in Arizona and has been spreading to cities across the country. Apartment complex owners in cities with this program can give prospective residents an addendum to sign along with a contract before moving in to the complex. By signing that addendum, the new resident would say that they're not a criminal. If that resident is caught engaging in criminal activity, they'll be evicted.
Odessa complex owners were training for the program at the Municipal Plaza on Friday. Owners that completed the training could add these addendums for new residents.
