Ohio Rev. Code § 505.50
The board of township trustees of a township or of a township police district, or a joint police district board, may purchase, lease, lease with an option to purchase, or otherwise acquire any police apparatus, equipment, including a public communications system, or materials that the township, township police district, or joint police district requires and may build, purchase, lease, or lease with an option to purchase any building or buildings and site of the building or buildings that are necessary for the police operations of the township or either district.
The boards of trustees of any two or more contiguous townships, or the boards of township trustees of one or more contiguous townships and the legislative authorities of one or more contiguous municipal corporations, by joint agreement, may unite in the joint purchase, lease, lease with an option to purchase, maintenance, use, and operation of police equipment for any other police purpose designated in sections 505.48 to 505.55 of the Revised Code, and to prorate the expense of that joint action on terms mutually agreed upon by the trustees in each affected township and the legislative authorities of each affected municipal corporation.
The board of trustees of a township or of a township police district, or a joint police district board, may enter into a contract with one or more townships, a municipal corporation, a park district created pursuant to section 511.18 or 1545.01 of the Revised Code, or the county sheriff upon any terms that are mutually agreed upon for the provision of police protection services or additional police protection services either on a regular basis or for additional protection in times of emergency. The contract shall be agreed to in each instance by the respective board or boards of township trustees, the board of county commissioners, the board of park commissioners, the joint police district board, or the legislative authority of the municipal corporation involved. The contract may provide for a fixed annual charge to be paid at the time agreed upon in the contract.
Chapter 2744. of the Revised Code, insofar as it is applicable to the operation of police departments, applies to the contracting political subdivisions and police department members when the members are serving outside their own political subdivision pursuant to such a contract. Police department members acting outside the political subdivision in which they are employed may participate in any pension or indemnity fund established by their employer and are entitled to all the rights and benefits of Chapter 4123. of the Revised Code, to the same extent as while performing services within the political subdivision.
