Indiana Lease Extension Addendum

This Lease Extension Addendum is built with Indiana as the governing state. These are the Indiana landlord-tenant rules that most often bear on it, with the statute for each.

Indiana rules at a glance

Indiana rules for a Lease Extension Addendum
Month-to-month terminationNotice equal to one rental period (one month)IC 32-31-1-4
Rent-increase notice30 days’ written notice before modifying the lease, unless the written lease provides otherwiseIC 32-31-5-4
Rent controlLocal units may not regulate rentIC 32-31-1-20
Rent increasesUnless a written rental agreement provides otherwise, a landlord must give the tenant at least 30 days’ written notice before modifying the rental agreement — which includes raising the rent (IC 32-31-5-4). Rent under a fixed-term lease can’t change mid-term unless the lease allows it.

Rent, late fees & rent increases

  • Late fees — Indiana has no statutory late-fee cap or mandatory grace period. The fee must be in the lease, and an excessive fee risks being struck by a court as an unenforceable penalty rather than a reasonable estimate of the landlord’s loss.
  • Rent increases — Unless a written rental agreement provides otherwise, a landlord must give the tenant at least 30 days’ written notice before modifying the rental agreement — which includes raising the rent (IC 32-31-5-4). Rent under a fixed-term lease can’t change mid-term unless the lease allows it.
  • Rent control — Cities, towns and counties may not regulate rental rates on private property — and may not regulate screening, deposits, applications, lease terms, disclosures or landlord fees either — unless the General Assembly authorizes it (IC 32-31-1-20).
