The superintendent shall have charge of the operation and maintenance of the state house, subject to such rules as the committee on rules of the 2 branches, acting concurrently, may adopt and all state parking areas related thereto. The superintendent shall also be responsible for oversight of the immediate state house loading dock spaces. The superintendent shall see that the chambers and lobbies of the general court and its committees are kept clean and in good order, shall superintend all ordinary repairs thereof and shall have charge of the current expenses for the care and preservation of the state house and for the ordinary repairs of the furniture and fixtures therein.

The commissioner of conservation and recreation shall utilize the members of the urban park rangers program, established under section 34B of chapter 92, to maintain security; provided, however, that the commissioner shall carry out the responsibility subject to such rules as the committee on rules of the 2 branches, acting concurrently, may adopt and shall not be subject to the authority of the superintendent. There shall be maintained an adequate passageway for foot passengers from north to south through the east wing or extension of the state house, to be kept open during such hours as the superintendent shall fix. The state house and most facilities used by the public, including hearing rooms, shall be accessible to, functional for and safe for use by persons with physical disabilities; and provided further, that the commonwealth shall make available a certain number of designated handicapped parking spaces for the general public.
