Hawaii: Late Rent Fee Limits
The short answer
Hawaii caps a residential late charge at 8% of the amount of rent due. The rental agreement must provide for the charge, but it may be written or oral, and the statute allows the charge when rent is not paid when due without creating a fee grace period. The statute does not expressly say whether a partial payment changes the calculation base or prescribe a one-time, daily, or compounding structure.

| Governing law | HRS §§ 521-21(f), 521-31, and 521-77 — 8% cap, agreement condition, nonwaiver, and consumer-protection complaint route |
|---|---|
| Maximum late fee | 8% of the amount of rent due (§ 521-21(f)) |
| Grace period | None stated; the agreement may impose a charge for rent not paid when due |
| Lease or notice requirement | The rental agreement must provide for the late charge (§ 521-21(f)); an agreement may be written or oral (§ 521-8), so no separate written notice is required |
| One-time or recurring | The total late charge may not exceed 8% of the amount of rent due; the statute states no separate one-time, daily, interest, or compounding mechanism |
| Calculated on | The statutory words are 'the amount of rent due.' The section does not expressly say whether a partial payment changes that base |
| Related fees & carve-outs | A public-assistance recipient whose agreement keys rent to receipt of a benefit check may establish a new due date under § 521-21(b); no returned-check or administrative fee is addressed in the late-charge subsection |
| If the fee is unlawful | A tenant may not waive Chapter 521 rights; the Office of Consumer Protection may receive, investigate, and try to resolve any Chapter 521 dispute. No late-fee-specific refund or damages multiplier is stated (§§ 521-31, 521-77) |

The cap is 8% of rent due
Hawaii Revised Statutes § 521-21(f) allows a late charge only "[w]here the
rental agreement provides" for one. The charge may apply when rent is "not
paid when due," and it may not exceed 8% of "the amount of rent due." If the
full $2,000 rent remains due, the maximum charge is $160.
The Code defines a rental agreement to include written or oral agreements.
Section 521-21(f) therefore does not require a signed addendum or a separate
written notice before the charge applies. It requires agreement authorization,
not a particular document format.
No statutory fee grace or accrual formula
The late-charge subsection uses the contractual due date as the trigger. It
does not create a fee-free grace period after that date. Any grace period must
come from the rental agreement.
The section caps the late charge but does not separately prescribe whether it
must be imposed once, may be described in daily increments, bears interest, or
compounds. Whatever structure the agreement uses, the late charge cannot
exceed the statutory 8% ceiling for the amount of rent due.
What trips people up
The statute does not say "unpaid balance." Its exact calculation phrase is
"the amount of rent due." For a partial payment, § 521-21(f) does not expressly
say whether the 8% runs against the original amount due or only the remainder.
Do not replace the statutory words with an unpaid-balance formula without
resolving that issue for the particular agreement and dispute.
A proposed 5% rule did not become law. SB 347 would have reduced the cap
from 8% to 5% and expressly limited the calculation to unpaid rent. It received
no action after referral and died when the 2025-2026 Legislature adjourned sine
die on May 8, 2026. The current official statute still says 8% of the amount of
rent due.
The public-assistance due-date rule is not a general grace period. Section
521-21(b) gives a qualifying public-assistance recipient an option to establish
a new due date through a one-time prorated payment. It does not give every
tenant extra fee-free days.
Common questions
Can a landlord charge a late fee that is not in the rental agreement? No.
Section 521-21(f) begins by requiring the rental agreement to provide for the
charge.
Must the agreement be written? No. Section 521-8 defines rental agreements
to include written and oral agreements.
Can a landlord charge more than 8% by splitting the fee into several
charges? The statute caps the late charge at 8% of the amount of rent due. It
does not provide a separate daily or multiple-charge allowance that enlarges
that ceiling.
Where can a tenant raise an excessive-fee dispute? Under § 521-77, the
Office of Consumer Protection may receive, investigate, and attempt to resolve
any dispute arising under Chapter 521. Section 521-31 also bars waiver of the
chapter's rights and remedies.
