 5-331. Certain  covenants  and restrictions in conveyances and other
  agreements affecting real property void as against  public  policy.  Any
  promise, covenant or restriction in a contract, mortgage, lease, deed or
  conveyance or in any other agreement affecting real property, heretofore
  or hereafter made or entered into, which limits, restrains, prohibits or
  otherwise  provides against the sale, grant, gift, transfer, assignment,
  conveyance, ownership, lease, rental, use or occupancy of real  property
  to  or  by any person because of race, creed, color, national origin, or
  ancestry, is hereby declared to be void as against public policy, wholly
  unenforceable, and shall not constitute a defense in any action, suit or
  proceeding. No such promise, covenant or restriction shall be listed  as
  a  valid  provision affecting such property in public notices concerning
  such  property.  The  invalidity  of  any  such  promise,  covenant   or
  restriction  in  any  such  instrument or agreement shall not affect the
  validity of any other provision therein, but no reverter shall occur, no
  possessory estate shall result, nor any right of entry  or  right  to  a
  penalty  or  forfeiture  shall accrue by reason of the disregard of such
  promise, covenant or  restriction.  This  section  shall  not  apply  to
  conveyances  or  devises  to  religious associations or corporations for
  religious purposes, but, such promise,  covenant  or  restriction  shall
  cease  to  be  enforceable  and  shall  otherwise  become subject to the
  provisions of this section when the real property affected  shall  cease
  to be used for such purpose.
