The legislative authority of a municipal corporation may purchase land within or without its boundaries and erect thereon suitable hospital buildings for the isolation, care, or treatment of persons having dangerous contagious disease, and provide for the maintenance thereof. The plans and specifications for such buildings shall be approved by the board of health of the city or general health district in which such hospital is to be located.

The legislative authority may issue bonds and apply the proceeds thereof to such construction if, at an election held for that purpose, two-thirds of the votes cast are in favor thereof. Such bonds may not exceed twenty-five thousand dollars, with a rate or rates of interest not to exceed the rate provided in section 9.95 of the Revised Code, and the principal shall be paid within ten years. After the erection of such buildings, the legislative authority each year may make such appropriations for their care, use, and maintenance as are necessary.
