N.Y. Comp. Codes R. & Regs. tit. 19 § 1204.17
Where a State authority or public benefit corporation participates in the construction of a new building or in the conversion, alteration, addition, or repair of an existing building and where upon its completion such building will be in the custody of an entity other than a State agency, administration and enforcement of the Uniform Code with respect to the construction, conversion, alteration, addition or repair will be the responsibility of the code enforcement agency generally performing those functions at the location of the work. The responsibility of a local code enforcement agency may be suspended during the period of the work if, acting pursuant to an express statutory grant, the authority or public benefit corporation exercises such discretion. In that event, a construction-permitting agency will be responsible for administration and enforcement of the Uniform Code with regard to the particular project. If previously designated as a construction-permitting agency, the particular authority or public benefit corporation participating in the project may serve as the agency responsible for administration and enforcement of the code. A construction-permitting agency will be similarly responsible where the Uniform Code is applied in lieu of local building construction regulations. Upon completion of the work, administration and enforcement of the Uniform Code will revert to the local agency ordinarily responsible for same.
