Indiana Rent Increase 2026: 30-Day Lease-Change Rule & 60-Day HOME Notice
Indiana uses a 30-day default written-notice rule for rental-agreement modifications unless the written agreement provides otherwise, while HOME-assisted units now require 60 days for rent increases. Learn how lease terms, local preemption and assisted-housing rules fit together.
The short answer
Indiana does not impose a general statewide percentage ceiling on ordinary private-market residential rent increases. Indiana Code § 32-31-1-20 also limits local governments from regulating rental rates for privately owned real property unless the General Assembly authorizes the regulation, subject to the statute's government-funded reduced-rent exception.
Timing is a separate question. Indiana Code § 32-31-5-4 provides a default rule: unless a written rental agreement provides otherwise, a landlord must give at least 30 days' written notice before modifying the rental agreement. Because the statute expressly makes the written agreement relevant, Max Rental Tools keeps Indiana automated timing review-gated instead of assuming 30 days is an absolute rule for every lease.
Indiana's 30-day rule is a rental-agreement modification rule
The important phrase in § 32-31-5-4 is that the landlord must give at least 30 days' written notice before modifying the rental agreement unless the written rental agreement provides otherwise. A proposed rent change can be a modification of the rental agreement, but the statute does not erase the actual lease terms.
Before relying on the 30-day default, identify whether there is a written lease, whether it contains its own notice or rent-adjustment provision, when the current term ends, and whether the proposed higher rent is supposed to begin during the current term or with a new term. A generic 30-day answer should not be used to rewrite a fixed-term agreement that does not permit the change.
No general statewide percentage cap does not mean no rules
Indiana's statewide framework does not supply a general percentage formula such as 3%, 5% or CPI for ordinary private rentals. Section 32-31-1-20 also prevents a county, city or town from creating its own private-rental-rate regulation unless the General Assembly has authorized it.
That amount rule is different from notice, contract, retaliation, fair-housing, subsidized-housing and other requirements. A landlord can still have an invalid effective date or violate another applicable rule even when the proposed percentage itself is not limited by a general statewide cap.
Written leases can change the notice analysis
Indiana's modification statute begins with an express written-agreement qualifier. That makes the signed lease a first-order input, not an afterthought. Check clauses addressing rent, renewal, automatic renewal, notice, term changes and any lawful adjustment mechanism before selecting the effective date.
For a fixed-term rental, distinguish a mid-term modification from a renewal-time proposal. The 30-day modification statute is not a blank check to disregard the rent promised for an unexpired term. If the parties are entering a new term, the renewal language and any other applicable notice requirement should be reviewed together with § 32-31-5-4.
HOME-assisted units use a separate 60-day rent-increase rule in 2026
Indiana Housing and Community Development Authority's February 2026 Federal Programs Ongoing Rental Compliance Manual states that once a lease is executed, lease terms generally cannot be modified without at least 30 days' written notice under Indiana Code § 32-31-5-4. It then adds a distinct current requirement for HOME-assisted units: rent increases require at least 60 days' written notice per the HOME regulation.
The same 2026 manual tells owners of HOME-assisted units to give at least 60 days' written notice before increasing rent. This is a program-specific rule. Do not convert the HOME 60-day requirement into a statewide rule for every ordinary apartment, house, condominium, townhome, room or other private rental, and do not reduce a covered HOME unit to the ordinary 30-day default.
Why assisted housing should be checked before a notice is generated
IHCDA administers multiple housing programs, and program rules can add rent limits, approval steps, tenant protections or different notice requirements. The current 2026 Federal Programs manual specifically identifies the new 60-day HOME rent-increase notice requirement while retaining the general Indiana lease-modification reference.
If a property participates in HOME, HTF, CDBG, NSP, Housing Choice Voucher, tax-credit or another assisted-housing program, identify the exact program before serving a notice. Program participation can change the workflow even though Indiana does not have a general statewide private-market percentage cap.
Examples: which Indiana rule should you start with?
Example 1: an ordinary private month-to-month rental has a written agreement that is silent about modification notice. Start with § 32-31-5-4's 30-day written-notice default, then verify the proposed effective date and the rest of the agreement. Example 2: a written lease expressly sets a different modification-notice rule. Review that clause because the statute says the written agreement can provide otherwise.
Example 3: a landlord wants to raise rent in the middle of a fixed one-year term. Start with the current lease and whether it actually authorizes that change; do not assume the 30-day default overrides the fixed term. Example 4: the unit is HOME-assisted. Start with the current IHCDA/HOME program rule requiring at least 60 days' written notice for the rent increase, along with any approval and rent-limit requirements.
Use Max Rental Tools after the Indiana path is identified
Use the Indiana state guide and rent-increase calculator to organize the current rent, proposed rent, percentage change, lease type, term dates and assisted-housing status. Because the written agreement can alter the ordinary statutory default, treat Indiana notice timing as review-required until the agreement and program status are confirmed.
After the correct path is established, use the Rent Increase Notice for a permitted increase, the Lease Renewal Notice when the proposed rent belongs to a future term, the Month-to-Month Rental Agreement when the periodic relationship needs documentation, and the Rent Ledger to preserve the rent-payment history. The linked Indiana General Assembly and IHCDA sources remain the controlling public references for the statewide and HOME-program rules described here.
Common questions
How much can a landlord raise rent in Indiana in 2026?
Indiana does not have a general statewide percentage cap for ordinary private-market residential rent increases. The lease, notice timing, assisted-housing rules and other applicable protections still need to be checked.
Does Indiana require 30 days' notice for a rent increase?
Indiana Code § 32-31-5-4 provides a default of at least 30 days' written notice before a landlord modifies a rental agreement unless the written rental agreement provides otherwise. Max Rental Tools keeps the timing review-gated because the written lease can change the analysis.
Can an Indiana lease require a different notice period?
Section 32-31-5-4 expressly begins with an exception when a written rental agreement provides otherwise. Review the signed agreement before assuming the statutory 30-day default controls.
Can an Indiana landlord raise rent during a fixed-term lease just by giving 30 days' notice?
Do not assume so. A fixed-term lease should be reviewed for any lawful rent-adjustment or modification provision. The 30-day default does not by itself establish that a landlord may rewrite an unexpired fixed-term rent obligation.
How much notice is required for a HOME-assisted rent increase in Indiana in 2026?
IHCDA's 2026 Federal Programs Ongoing Rental Compliance Manual states that HOME-assisted rent increases require at least 60 days' written notice per the applicable HOME regulation.
Can an Indiana city create its own rent cap?
Indiana Code § 32-31-1-20 generally prevents local units from regulating rental rates for privately owned real property unless the General Assembly authorizes the regulation, with a statutory exception involving certain government-funded reduced-rent property.
