Does the ordinance require me to evict for one criminal incident?

 No. The ordinance does require the use of a Crime Free Lease Addendum or similar wording in the body of the lease that makes criminal activity a cause for eviction. The ordinance does not require an eviction based on minor criminal activity. It simply provides the rental property owner the tool and ability to deal with a problem if they choose or need to. The Crime Free Lease Addendum was developed by HUD and is used in Section 8 leases utilized by housing authorities. Evictions based on this concept were upheld by the U.S. Supreme Court in 2002 (see Oakland Housing Authority v. Rucker and Department of' Housing and Urban Development v. Rucker).
