Idaho does not cap how large a residential security deposit may be. Unused deposit plus an itemized list is generally due within 21 days, or 30 days if the lease says so (Idaho Code § 6-321).
A month-to-month tenancy generally takes at least one month’s written notice (Idaho Code § 55-208).
Idaho does not prescribe a statewide 24-hour entry statute. Put a reasonable-notice entry clause in the lease. Emergency entry is customary.
A Idaho rent increase should be in writing. Many landlords use at least the same notice they would use to end a month-to-month tenancy. A month-to-month tenancy generally takes at least one month’s written notice (Idaho Code § 55-208). The lease may require more. Local rent-control rules can cap the amount even when the notice period is met.
