Indiana Code Title 36. Local Government § 36-10-10-27

Sec. 27. The city may construct an addition to the convention center leased by it under this chapter.  The construction of an addition is subject to all statutes generally applicable to the construction of an addition to a city building owned by a city.  In order to provide money for such purposes, a city may issue its general obligation bonds or appropriate money from its general fund or from any other funds or money available that could be used for such purposes as if the building were owned instead of leased by the city.
