*  In 2012, the Missouri General Assembly passed a statute invalidating restrictive covenants relating to discrimination (R.S.Mo. Sec. 442.403).  This statute affected four of the nine subdivisions within the Country Side Homes Association.  When the CSHA Board became aware of the new statute in 2020, and in observance of Fair Housing law, the Board recorded with the Jackson County, Missouri Recorder of Deeds the following four Amendments regarding the illegal declarations:

Amendment to the Rockhill Park Illegal Declarations (recorded 12/9/2020)
Amendment to the Country Side Extension Illegal Declarations (recorded 12/9/2020)
Amendment to the Southwood Extension Illegal Declarations (recorded 12/9/2020)
Amendment to the South Country Side Illegal Declarations (recorded 12/9/2020)
