R.I. Gen. Laws § 42-64.9-10
Notwithstanding the provisions of any municipal charter or any other general, special or local law to the contrary, real property taxes for a certified building and tangible property taxes of the owner or owners of a certified building for tangible property used in the certified building may be exempted from payment, in whole or in part, notwithstanding the valuation of the property or the rate of tax, by vote of the city or town council to the extent deemed appropriate by the city or town council to carry out the purposes of this chapter. This section shall be construed to provide a complete, additional and alternative authority for the city or town council to grant exemption or stabilization of real or tangible property taxes with respect to certified buildings, and the granting of tax exemption or stabilization by the city or town council under the provisions of this section does not require the taking of any other proceedings or the happening of any condition, except for the vote of the city or town council.
