Where do the Idaho rent increase notice laws come from?

The rules above come from Idaho Code 55-304 and Idaho Code 55-306. Each source is linked on this page. We last checked them in October 2026.

Good to know

The rule is in Idaho Code 55-304(2), amended in 2024 and renumbered from 55-307 in 2025.

55-304(1) still lets a landlord change month-to-month lease terms on 15 days' notice before the month ends, but (2) requires 30 days' written notice for residential rent increases.

What this means in practice

Put the rent increase in writing, state the new amount and the date it takes effect, and keep a copy along with proof of how and when it was delivered. Count the notice period from the date the tenant actually receives the notice, and check whether your state adds extra days for mailed notices.

Check local law as well as state law. Some cities and counties have rent stabilization ordinances, registration rules, or longer notice periods, and subsidized or rent-regulated units often follow separate federal or program rules.

A rent increase cannot be used to retaliate against a tenant for making a repair request or complaint, or to discriminate against a protected group. If the timing of an increase could look retaliatory, document the business reason for it.

General information, not legal advice. Laws change, and cities can add their own rules, so check the current statute before you rely on it.
