Section 1902. Certification of assessing units

1.  Whenever an assessing
  unit other than a special assessing unit  or an approved assessing  unit
  which  has  or  has  had  in  effect  a  local  law  adopted pursuant to
  subdivision one of  section  nineteen  hundred  three  of  this  article
  undertakes  a  revaluation  or  an  update,  the  governing body of such
  assessing unit may  apply  to  the  state  board  for  certification  or
  recertification  as an "approved assessing unit".  The state board shall
  monitor the progress of such revaluation or update for  the  purpose  of
  determining  whether  or  not  such  assessing unit will be eligible for
  certification or recertification as an approved assessing unit.
    2. Upon application by the governing body of any assessing unit, filed
  no later than one hundred twenty days prior to  the  completion  of  the
  first  tentative  assessment  roll  on  which such revaluation or update
  shall be entered, the state board  shall  certify  or  recertify  as  an
  approved  assessing  unit  any such assessing unit which has completed a
  revaluation or update. Such certification or  recertification  shall  be
  based on the first assessment roll on which the revaluation or update is
  entered,  provided  however,  if such revaluation was completed prior to
  December thirty-first, nineteen hundred eighty-one,  such  certification
  shall be based upon the latest completed assessment roll.  A revaluation
  or  an  update  shall  be  deemed  to  be completed when its results are
  available for entry on a tentative assessment roll. The  last  date  for
  filing  of  an  application for certification may be waived by the state
  board,  if  circumstances  warrant.  Notice  of  such  certification  or
  recertification,  or  denial  thereof, shall be filed by the state board
  with the chief executive officer of such assessing unit  no  later  than
  thirty  days  prior  to the completion of the first tentative assessment
  roll following application pursuant to this subdivision.
    3. Upon filing an application for approved assessing unit status,  the
  governing  body  of  a  city, town or county shall forward to the school
  authorities of each school district located partially in such city, town
  or  county  a  notice  prepared  by  the  state  board  summarizing  the
  provisions  of  section  nineteen  hundred  three-a  of this article and
  specifying the last date provided for  in  subdivision  one  of  section
  nineteen  hundred  three-a of this article for the school authorities to
  file a notice of intent to use homestead  and  non-homestead  tax  rates
  with  each  assessor  who  prepares  an assessment roll used to levy the
  school district's taxes.
    4. If the governing body of an approved assessing unit fails to  adopt
  the  provisions  of section nineteen hundred three of this article so as
  to apply to the revaluation or update specified in  subdivision  two  of
  this  section,  the  certification  of the approved assessing unit shall
  expire. Nothing contained herein shall be construed so  as  to  prohibit
  such  an assessing unit from reapplying for certification as an approved
  assessing unit on the basis of a future revaluation or update.
