A late fee is only collectible if your lease authorizes it. General information, not legal advice.

The Idaho late-fee rules

  • Maximum fee: No statutory cap — must be reasonable
  • Grace period: None — the lease sets it
  • Idaho statutes don't address residential late fees — the lease governs
  • The $20-or-20% formula some charts list for Idaho is a self-storage rule, not residential

Rules as of August 2026. Statutes change — verify with the current text before relying on a number, and check city and county ordinances, which can be stricter. This is general information, not legal advice; consult a Idaho attorney for your situation.
