N.Y. Real Property Tax Law § 738: Residential assessment ratio

§ 738. Residential assessment ratio. 1. (a) For the purposes of this

title, sixty days prior to the date for the filing of the tentative

assessment roll of an assessing unit, the commissioner shall determine

the residential assessment ratio for such assessing unit. The

residential assessment ratio shall be equal to the level of assessment

of residential property in the assessing unit as determined in the

market value survey used or to be used to calculate the state

equalization rate for that assessment roll pursuant to article twelve of

this chapter, subject to the provisions of paragraph (b) of this

subdivision.

(b) The commissioner shall increase or decrease the residential

assessment ratio to account for a change in level of assessment in the

total assessed value of residential real property or, if not available,

of all taxable real property. For purposes of this section, "change in

level of assessment" has the meaning set forth in section twelve hundred

twenty of this chapter except that a change in level of assessment shall

be determined with reference only to residential real property if the

necessary information is available.

(c) The residential assessment ratio shall be made available at the

office of the county director of real property tax services, the office

of the county clerk and the office of the assessor or, in a city with a

population of one million or more, the office of the tax commissioner of

such city. Such ratio shall be provided to the office of court

administration for distribution to small claims hearing officers.

2. For purposes of this section, assessing units participating in a

coordinated assessing program pursuant to section five hundred

seventy-nine of this chapter shall be considered to be a single

assessing unit.
