N.Y. Comp. Codes R. & Regs. tit. 9, § 2202.3
(1) This section and sections 2202.4 to 2202.12, inclusive, of this Part set forth specific standards for the increase of a maximum rent.

On or after November 22, 1963, where any housing accommodations were vacated other than by voluntary surrender of possession or in the manner provided by Part 2204 of this Title, the administrator may, after having due regard to the equities involved, bar adjustments of maximum rents for any and all accommodations in such structure, pursuant to section 2202.4(b) and (c) of this Part, except for work which:

(c) Except as provided in subdivision (g) of this section and section 2202.19 of this Part, no landlord shall be entitled to an increase in the maximum rent on any ground unless he certifies that he is maintaining all essential services furnished or required to be furnished as of the date of the issuance of the order adjusting the maximum rent, and that he will continue to maintain such services so long as the increase in such maximum rent continues in effect; nor shall any landlord be entitled to any increase in maximum rent on any ground where an agency of the city having jurisdiction certifies that the housing accommodation is a fire hazard, or is in a continued dangerous condition or detrimental to life or health or is occupied in violation of law; nor shall any landlord be entitled to any increase where the landlord has not removed the violation recorded against such property as shown in the report of search required under subdivision (b) of this section.
(d)
(c) That portion of the amount of increase computed under sections 2202.8 through 2202.11 of this Part, as is properly attributable to the controlled housing accommodations, shall be apportioned among them in the manner prescribed in section 2201.4 of this Title for the apportionment of the maximum gross building rental. Each controlled housing accommodation shall bear no more than that portion of the amount of increase as is properly attributable to such housing accommodation, whether or not the amount so attributed shall be fully collectible by reason of an existing lease or, in the case of an adjustment pursuant to section 2202.8, 2202.9 or 2202.10 of this Part, by reason of the limitations provided in section 2201.6 of this Title.
