How Much Can a Landlord Raise Rent By in Idaho?

In Idaho, landlords can raise the rent by any amount and for any reason as long as they give proper notice, don’t do so during the fixed term of a lease, and aren’t doing so for certain discriminatory reasons.

When Can a Landlord Raise Rent in Idaho?

In Idaho, landlords can raise the rent for any reason as long as it is not discriminatory in nature and proper notice is given.


Idaho law requires that rent increases on mobile homes be applied evenly to all tenants living in similar units throughout the community.

When Can’t a Landlord Raise Rent in Idaho?

In Idaho, landlords cannot raise the rent during the middle of a lease’s fixed term or for certain discriminatory reasons (like race or age).

The Federal Fair Housing Act prohibits discrimination due to:

  • Age
  • Race
  • Gender (including gender identity)
  • Sexual orientation
  • Religion
  • Nationality or origin
  • Familial status
  • Disability

If the rental unit is a mobile home, Idaho law prevents landlords from increasing rent in retaliation. The law does not specify what time period between the tenant action and rent increase qualifies as retaliation, so landlords should act in good faith when increasing rent.

Rent increases on mobile home tenants are considered retaliatory if they are in response to a tenant:

  • Filing a complaint with the appropriate agency regarding the health or safety of the property
  • Complaining to the landlord regarding the maintenance or condition of the community, rent charged, or rules
  • Joining or organizing a tenants’ group, union, or community association
  • Hiring a lawyer to represent them

Idaho state law does not address retaliatory rent increases for other types of rental units.

How Much Notice is Needed to Raise Rent in Idaho?

In Idaho, landlords cannot raise the rent during a lease term and must give 30 days’ notice to increase the rent. However, if the rental unit is a mobile home, the landlord must give 90 days’ notice.

How Often Can Rent Be Increased in Idaho?

Landlords in Idaho can increase the rent as often as they choose as long as they provide sufficient notice each time, unless the rental unit is a mobile home.

Landlords of mobile homes can increase the rent no more than once every six months.
