2006 New York Code - Option To Change To Single Appointed Assessor.

 
    §  328.  Option to change to single appointed assessor. In any city or
  town which has retained the office of elective assessor, the legislative
  body of such city or town may adopt a local law providing that from  and
  after  a date set forth in such local law, which date must be within one
  year after the date on which such local law was adopted, there shall  be
  but  one  assessor, to be appointed as provided in section three hundred
  ten of  this  title.  The  legislative  body,  in  its  discretion,  may
  determine  that  a  local  law adopted pursuant to this section shall be
  subject to a mandatory or permissive referendum in the manner prescribed
  in section twenty-three or twenty-four of the municipal home  rule  law,
  as  the  case  may  be. Upon the expiration of forty-five days after the
  adoption of such a local law, or if such  local  law  is  submitted  for
  approval  by  the electors, upon approval of such local law, the term or
  terms of office of all assessors then in office shall terminate  on  the
  date  set forth in such local law for the establishment of the office of
  an appointed assessor.
