How much notice is required to raise the rent in Iowa?

Verified July 10, 2026 All Iowa topics →

Iowa landlords must give every tenant written notice of any rent increase at least 30 days before it takes effect — an express statutory requirement in Iowa Code 562A.13(5), not merely a convention derived from termination notice — and the increase cannot take effect before the tenant's current lease term or renewal expires.

There is no limit on the size or frequency of increases: Iowa has no rent control, and since 2000 state law has expressly barred every city and county from adopting any ordinance limiting the rent that can be charged for private residential or commercial property. One big exception lives in a different chapter: tenants renting a lot in a manufactured home community or mobile home park are owed 90 days' written notice of a lot-rent increase under Iowa Code 562B.14(7), a protection the legislature expanded in 2022. A 2026 bill that would have required 180 days' notice and CPI-based justification for mobile-home lot rent increases (SF 2225) died without a committee vote when the legislature adjourned in May 2026.

Iowa rent increase notice at a glance

Notice — month-to-month	30 days
Varies by increase size	Not addressed by statute
Fixed-term leases	562A.13(5), second sentence: the effective date of any rent increase 'shall not be sooner than the expiration date of original rental agreement or any renewal or extension thereof' — an express statutory ban on mid-term increases, independent of contract law.
Statewide rent control / stabilization	No
Rent control details	No statewide rent control. Iowa expressly preempts local rent regulation in two parallel provisions: Iowa Code 364.3(9) (cities) and 331.304(10) (counties), each barring any ordinance 'imposing any limitation on the amount of rent that can be charged for leasing private residential or commercial property,' with a carve-out only for property in which the city or county itself has a property interest. The preemption has been in force since 2000 (2000 Acts ch 1083) — not 2019 as often claimed — and contains no manufactured-housing exception, so cities cannot cap mobile-home lot rents either.
Local rent control preempted	Yes
Frequency limits	Not addressed by statute

Notes and caveats

Iowa is one of the few URLTA states with an EXPRESS rent-increase notice statute — 562A.13(5) ('Each tenant shall be notified, in writing, of any rent increase at least thirty days before the effective date') — so do not present the 30 days as a 562A.34 derivation; 562A.34(2) (30-day month-to-month termination notice, keyed to the periodic rental date) is cited as context because the two provisions work together for month-to-month tenants. Traps debunked: (1) preemption is routinely miscited as 364.3(12) — that subsection is the 2017 employment-terms preemption; the rent provisions are 364.3(9) and 331.304(10); (2) the claim that Iowa 'banned local rent control in 2019' is folklore — the Iowa Code 1999 edition lacks the provision and the 2001 edition contains it, with 2000 Acts ch 1083 appearing in both sections' histories; (3) the 30-day figure applies to chapter 562A dwellings only — manufactured home community / mobile home park lot tenancies get 90 days under 562B.14(7) (raised from 60 days by 2022 Acts ch 1070, applicable to increases first noticed on or after 2022-05-17), and secondary sources regularly mix the two chapters. Dead-bill debunk: SF 2225 (2026) would have replaced 562B.14(7) with a 180-day notice plus a CPI-justification regime; it died in Senate Judiciary subcommittee at sine die 2026-05-03, so claims of a pending or enacted 180-day Iowa notice are false. notice_varies_by_increase_size and frequency_limits are null — no such provisions exist in chapter 562A.

How this record was verified: Direct read of statute text on the official Iowa Legislature site (legis.iowa.gov), Iowa Code 2026 section PDFs: 562A.12, 562A.9, 562A.13, 562A.19, 562A.34, and 562A.35 each read twice — official PDF plus independent FindLaw mirror stated current as of 2026-01-01 — with every load-bearing figure matching verbatim (2-month deposit cap, 30-day return clock and its dual trigger of termination plus receipt of the tenant's mailing address or delivery instructions, first-5-years deposit interest to landlord, 1-year forwarding-address forfeiture, punitive damages capped at twice the monthly rental payment, $700 late-fee threshold with $12/day-$60/month and $20/day-$100/month tiers, 30-day written rent-increase notice, 24-hour entry notice, 30-day month-to-month termination notice, one-month's-rent damages floor for unlawful entry). Also read once (official): 562A.28 and 562A.29 (cross-referenced entry rights), 331.304 (county rent-control preemption), and chapter 562B sections 562B.10/562B.13/562B.14 for cross-chapter trap mapping. Rent-control preemption 364.3(9) verified against three official Code editions (2026, 2019, 2001) plus the 1999 edition negative check proving enactment by 2000 Acts ch 1083, not 2019. Pending-bill check 2026-07-10: 91st GA adjourned sine die 2026-05-03; SF 2225 (omnibus tenant bill: third late-fee tier at $1,400 rent, 180-day mobile-home rent notice) died in Senate Judiciary subcommittee; HF 481/482 (2025 mobile-home protections) also died; 2026 enacted housing bills (SF 2369 ADUs, SF 2448 HOA disclosure, SF 2472 FirstHome) touch none of the four topics.
