R.I. Gen. Laws § 30-10-6: Rental of armories for nonmilitary purposes.

The adjutant general may authorize the use of any armory under his or her control, for nonmilitary purposes, subject to such rules and conditions as he or she may prescribe, that are lawful and approved, provided that the person, corporation, organization, or society to whom the use may be authorized shall pay in advance to the adjutant general such a sum for the use thereof as may be prescribed by the adjutant general. This sum shall in no case, where admission is charged, be less than the fair rental value of halls of a similar nature, in the same or a similar city or town. These persons, corporations, organizations, or societies shall, if required by the adjutant general, furnish a bond, with good and sufficient surety, to protect and indemnify the state from loss or damage to the armory, or to any federal or state property, or to the property of any military organization or members thereof, contained therein.
