Title 2 - Private Property
485-S*2 - Residential Reassessment Exemption.

(i) The property must be a one-, two-, or three-family residential
property, provided that in an approved assessing unit dwelling units
held in condominium form of ownership that are classified in the
homestead class shall also be eligible;
(ii) The property must be eligible to receive the STAR exemption
authorized by section four hundred twenty-five of this title or the
owner or owners must be eligible to receive the personal income tax
school tax relief (STAR) credit authorized by subsection (eee) of
section six hundred six of the tax law, as added by section six of part
A of chapter sixty of the laws of two thousand sixteen, for such
property.
(iii) In any given year, the owner or owners receiving the exemption
pursuant to this section must be the same as the owner or owners that
appeared on the assessment roll upon which the revaluation is
implemented;
(iv) The property must have a Certificate of Occupancy or a temporary
Certificate of Occupancy; and
(v) The property must not have any delinquent taxes as of the taxable
status date for the roll on which an exemption is applied.
(b) In addition to the criteria provided in paragraph (a) of this
subdivision, the town assessing unit may further limit the eligibility
to eligible residential property whose full value increase exceeded a
set value threshold as specified in their local law adopting the
provisions of this section. If provided by local law, the town assessing
unit may elect to grant exemptions to only those properties that do not
have building code violations.
3. Exemption calculation. (a)(i) The exemption shall be computed with
respect to a percentage of the "exemption base." The exemption base
shall be the amount by which the assessed value of a property on the
assessment roll upon which the revaluation is implemented exceeds the
prior year's equalized assessed value, as determined in the initial
year. The prior year's equalized assessed value shall be determined by
applying the applicable change in level of assessment factor to the
prior year's assessed value. Such exemption base shall not include
increases due to a physical improvement or a removal or reduction of an
exemption on property.
(ii) Any increase in the assessment of a property due to physical
changes in the year following the implementation roll shall not be
eligible for the exemption. In the event that any portion of a parcel is
fully or partially removed from the roll during the year following the
implementation roll by reason of fire, demolition, destruction or new
exemption, the assessor shall reduce the exemption for any remaining
portion in the same proportion assessment is reduced for such fire,
demolition, destruction or new exemption. If a property's revaluation
assessment is reduced pursuant to title one-A of article five, or title
one or one-A of article seven of this chapter, the exemption shall be
recomputed accordingly.
(b)(i) The exemption shall be to the extent of sixty-six per centum of
the exemption base in year one and thirty-three per centum of the
exemption base in year two.
(ii) The following table shall illustrate the computation of the
exemption:
Year of exemption Percentage of Exemption
1 66% of exemption base
2 33% of exemption base
4. Granting of exemption. (a) Such exemption shall be granted only
upon application by the owner or owners of such real property on a form
prescribed by the commissioner. Such application shall be filed with the
assessor on or before the appropriate taxable status date for the
assessment roll upon which the revaluation is implemented.
(b) If the assessor is satisfied that the applicant is entitled to an
exemption pursuant to this section, he or she shall approve the
application and the taxable assessed value shall be reduced by the
exemption, as in this section provided commencing with the assessment
roll prepared after the taxable status date. The assessed value of any
exemption granted pursuant to this section shall be entered by the
assessor on the assessment roll with the amount of the exemption shown
in a separate column.
(c) In the event that the residential property granted an exemption
pursuant to this section transfers ownership or otherwise ceases to meet
the eligibility requirements of the exemption in subdivision two of this
section, the exemption granted pursuant to this section shall be
discontinued. Upon determining that an exemption granted pursuant to
this section should be discontinued, the assessor shall mail a notice so
stating to the owner or owners thereof at the time and in the manner
provided by section five hundred ten of this chapter.
