Idaho Rental Property Laws and Regulations

Idaho rental properties are governed primarily by state statutory frameworks that outline requirements for rent increases, security deposits, lease modifications, eviction procedures, and property habitability standards.

Updated with grounded research as of 2026-07-21.

The short answer

Yes, Idaho regulates rental properties primarily through specific state statutes under Title 6 and Title 55 of the Idaho Code. These state laws establish baseline requirements for lease termination, notice periods for rent increases, security deposit returns, and basic habitability standards. Simultaneously, Idaho law strictly limits the authority of local municipalities to enact rent control or mandate landlord participation in optional federal assistance programs. Specific lease dispute outcomes ultimately depend on the terms of the signed contract and judicial interpretations. Distinct rules also apply to commercial properties, mobile home parks, and specialized housing.
