Key numbers

Rent increase notice
30 days
written, before the increase takes effect
Idaho Code § 55-304(2)

Rent increases

Give the tenant written notice of any rent increase at least 30 days before it takes effect. This applies to every residential lease and overrides the older 15-day rule for month-to-month changes.

Idaho Code § 55-304(2)

  • For a month-to-month lease, other terms may be changed by written notice given at least 15 days before the end of the month; the new terms take effect at the end of the month if the tenant stays on. Idaho Code § 55-304(1)
  • Adding a fee, fine or other cost that a written rental agreement does not include takes 30 days' written notice, and no fee may exceed the amount the agreement states. Idaho Code § 55-305(2) See Rent payments and late fees on the Idaho page
  • Idaho sets no limit on the amount of rent, and cities and counties may not regulate rent for private residential rentals. Idaho Code § 55-305(4) Idaho Code § 55-306 See Rent control and local rules on the Idaho page

Rent control and local rules

Idaho bars cities, counties and other local governments from enacting, keeping or enforcing any ordinance or resolution that would regulate the rent, fees or deposits charged for private residential rentals, or force owners into an optional federal housing assistance program.

Idaho Code § 55-306

Retaliation

The general landlord-tenant chapters (title 6, ch. 3 and title 55, chs. 2 and 3) have no retaliation section, but Idaho's Human Rights Act makes it unlawful to treat anyone worse because they opposed a practice the Act forbids or filed a charge or took part in an investigation or case under it, and the Manufactured Home Residency Act bars retaliation against residents of rented lots in a manufactured home community.

Idaho Code title 6, ch. 3 Idaho Code title 55, ch. 2 Idaho Code title 55, ch. 3 Idaho Code § 67-5911 Idaho Code § 55-2015

  • A manufactured home community landlord may not end or refuse to renew a lot tenancy, raise rent, cut services or threaten eviction because a resident complained in good faith to a code agency or to the landlord, joined a resident association or hired counsel. Idaho Code § 55-2015
  • A tenant's statutory remedy for conditions and deposits is a lawsuit after a 3-day notice. Idaho Code § 6-320(d) See Tenant repair remedies on the Idaho page
In the Rentari Idaho lease

As a lease term, the lease bars the landlord from taking adverse action against the tenant for exercising rights or reporting code violations.
