Indiana: Rent Increase Notice Requirements
The short answer
Indiana has no general state statute requiring advance notice of a rent increase or capping the amount for an ordinary residential tenancy. Its one-month written-notice rule determines a tenancy at will rather than changing rent, and state law generally bars local units from regulating private rental rates.

| Governing law | No general increase statute; IC 32-31-1-20 preempts local private-rental-rate regulation, and IC 32-31-8.5 addresses retaliation |
|---|---|
| Advance notice required | No general state rent-increase period; IC 32-31-1-1's 1-month written notice determines a tenancy at will |
| Statewide limit on the increase | No general statewide cap |
| Homes and landlords exempt from the cap | N/A No statewide cap; local-rate preemption excludes specified government-supported reduced-rent property (IC 32-31-1-20(a)) |
| How often rent may increase | No general statewide frequency limit |
| Notice form, content, and service | No general statutory rent-increase form, content, or service rule |
| Increase during a fixed lease | No general increase statute; retaliation law recognizes a comparable-market increase during the term only if provided for in the rental agreement (IC 32-31-8.5-5(b)(2)) |
| Tenant's remedies | No general defective/excessive-increase remedy stated; a rent increase in response to protected activity is a prohibited retaliatory act (IC 32-31-8.5-4 to -5) |

Indiana's ordinary state-law framework
Indiana does not prescribe a general notice period, percentage cap, or
frequency limit for an ordinary residential rent increase. It also generally
prevents a local unit from filling that gap: IC 32-31-1-20(b) bars local
regulation of private rental rates unless the General Assembly authorizes it.
Subsection (a) excludes specified government-supported reduced-rent property
from that preemption section.
What trips people up
The one-month notice in IC 32-31-1-1 is a termination rule. It says a
tenancy at will may be "determined"—ended—by one month's written notice. It does
not say that one month's notice changes the rent while the existing tenancy
continues, so it is not a general rent-increase period.
Indiana's retaliation chapter does not create a general cap, but it does reveal
how a lease term matters. IC 32-31-8.5-5(b)(2) says the retaliation ban does
not prohibit raising rent to the amount charged for comparable market rentals,
including during the agreement term if the rental agreement provides for the
increase. That narrow safe harbor should not be converted into a general
statutory power to rewrite every fixed lease.
Common questions
Does Indiana require one month's notice of a rent increase?
No general state statute says so. Section 32-31-1-1 uses one month's written
notice to determine a tenancy at will, not to impose a new rent while preserving
the same tenancy.
Can an Indiana city adopt rent control?
Generally no for privately owned real property. IC 32-31-1-20(b) bars a
local unit from regulating rental rates unless an act of the General Assembly
authorizes the regulation.
What if the increase follows a tenant's code complaint?
An increase made in response to protected activity is a "retaliatory act" under
IC 32-31-8.5-4, and § 32-31-8.5-5(a) prohibits it subject to the
chapter's exceptions. The cited chapter states no special rent-increase damages
formula.
