Idaho Late Rent Fee Rules

What Idaho law says

• AG manual: fees charged to residential tenants must be reasonable, including late rent fees.
• AG manual: fees cannot be greater than the amount agreed upon in the lease.
• AG manual: the lease governs the date rent is due and the consequences of not paying on time or in full.
• The manual does not state a statutory grace period or a dollar cap.
• The manual lists 55-305 (limitation on fees for tenants of a rental property) in its appendix by title only.

Steps for a landlord

• Put the late fee amount and trigger in the written lease.
• Keep the fee reasonable.
• Do not charge more than the lease states.
• Read 55-305 or ask an attorney before setting the amount.

What to put in the notice

• The lease clause that allows the late fee
• The rent due date and any grace period
• The late fee amount and the total now owed
• How and where the tenant can pay
• The date and your signature

Things to watch

• The page we read does not give a grace period or a numeric cap.
• The page does not define what is reasonable; check 55-305 or a local attorney.
• Cities and counties can add their own rules, including rent control and extra notice requirements. Check your local rules too.
