Idaho Landlord-Tenant Laws
Local rent regulation in Idaho
Idaho law bars cities and counties from adopting any ordinance that would regulate rent, fees, or deposits for private residential rentals, or force owners into optional housing-assistance programs, leaving local governments free to manage only housing they themselves own.

Idaho Security deposits
Idaho puts no cap on security deposits, but the landlord must refund the deposit within 21 days after the tenant surrenders the premises — or within a different period the lease fixes, never more than 30 days after surrender.
Idaho Rent increase notice
Idaho landlords must give at least 30 days' written notice before any rent increase takes effect, in every residential lease including month-to-month tenancies (Idaho Code § 55-304(2)) — the same 30-day written notice applies to a decision not to renew the lease.
Idaho Late fees
Idaho has no numeric cap on late fees, but since July 1, 2023 state law requires every fee charged to a residential tenant — late-payment fees included — to be reasonable, and bars landlords from charging any fee, fine, assessment, or interest that exceeds what the rental agreement states or that is not in the agreement at all (Idaho Code § 55-305).
Idaho Entry notice
Idaho has no statute requiring landlords to give any advance notice before entering a rental unit — entry rights come entirely from the lease.
Idaho Eviction process
To evict a residential tenant in Idaho, serve a written 3-day notice - pay-or-quit for unpaid rent under Idaho Code 6-303(2), or cure-or-quit for any other lease covenant under 6-303(3) - and if it expires unmet, file an unlawful detainer action in the district court for the county where the property sits, which the magistrate division hears.
Idaho mobile home park laws
Idaho's Manufactured Home Residency Act, chapter 20 of title 55 of the Idaho Code, governs the tenancy of a resident who owns the home and rents the lot beneath it in a community of two or more homes, and it is a notice statute rather than a price or security statute: lot rent may be raised only after the term expires and only on 90 days' written notice, an increase must be uniform across the community or across a rent tier, and there is no ceiling on the amount at state or local level.
