Indiana does not have any statutes on rent withholding or repair and deduct remedies for tenants.
For an overview of tenant rights in Indiana, see http://www.owencountyindiana.org/economic_development/TenantsRights.pdf.
Check your local housing ordinances for any city or county rules that cover tenant rights when it comes to repairs. Contact your local building or housing authority. To find yours, call your mayor or city manager’s office or check your city or county website.
