Idaho Late Fee Laws

Last reviewed: July 10, 2026

Maximum late fee
No statutory cap
Grace period
None required
Statute
Idaho Code tit. 6, ch. 3

Idaho sets no statutory dollar cap on residential late fees — Idaho Code tit. 6, ch. 3 governs the landlord–tenant relationship, and courts still expect a late fee to be a reasonable estimate of actual damages rather than a penalty.

Idaho's statute doesn't impose a waiting period, so the lease controls when a late fee may be charged. Charging from day one is legal here only if the lease says so explicitly.

Idaho has no late fee statute. A clearly written lease clause is the whole ballgame — amount, trigger day, and structure should all be explicit.
