Indiana Code Title 36. Local Government § 36-7-19-4

Sec. 4. In connection with:

wholly or partly within its jurisdiction, a political subdivision may contract with a housing authority or the federal government with respect to the sums (if any) that the housing authority or the federal government agrees to pay, during any year or period of years, to the political subdivision for the improvements, services, and facilities to be furnished by it for the benefit of the housing project.  However, the amount of these payments may not exceed the estimated cost to the political subdivision of the improvements, services, or facilities to be furnished.  The absence of a contract for payment does not relieve the political subdivision of the duty to furnish, for the benefit of the housing project, improvements, services, and facilities that the political subdivision usually furnishes without a service fee.
