Hawaii Security Deposit Laws: The One-Month Cap, 14-Day Return, and Treble Penalty

Hawaii security deposit law is set almost entirely by one statute — Hawaii Revised Statutes section 521-44, part of the Residential Landlord-Tenant Code. It caps the ordinary deposit at a single month’s rent, allows a separate pet deposit of up to one more month, and gives a landlord just fourteen days after the tenancy ends to return the deposit and deliver a written, itemized notice of anything kept. The teeth are sharp: a landlord who misses that fourteen-day window forfeits the right to keep any of the deposit, and one who wrongfully and wilfully withholds can be ordered to pay the tenant three times the amount held. This guide walks the whole Hawaii framework end to end — how much you may collect, the pet-deposit rule, what you can and cannot deduct, the fourteen-day deadline and the written notice, the forfeiture and treble-damages penalties, and the small-claims path if a dispute cannot be resolved.

Whether you own one condo on Oahu or a small portfolio across the islands, the rules below apply the same way, because Hawaii Revised Statutes section 521-44 governs statewide. There is no separate county deposit cap and no local interest ordinance layered on top, which makes Hawaii simpler than some mainland states — but the fourteen-day clock is unforgiving, so the discipline is in the timing, not the arithmetic. Everything here is general information, not legal advice; confirm the current figures and consult a licensed Hawaii attorney before acting on a specific dispute.

Below, a short overview video summarizes the Hawaii deposit rules; the sections that follow break down each piece in detail — the one-month cap and the pet deposit, deductions versus normal wear and tear, the fourteen-day return timeline and written notice, the forfeiture rule, the treble-damages penalty, the move-out walkthrough, and the small-claims path if a dispute cannot be resolved.

The single most important number in Hawaii deposit law is the cap. Under Hawaii Revised Statutes section 521-44, a landlord may require a security deposit not in excess of one month’s rent. That is the whole ordinary limit — there is no furnished-versus-unfurnished distinction the way some mainland states once had, and Hawaii has never allowed the two-and-three-month deposits common elsewhere. One month’s rent is the ceiling for the standard deposit, full stop.

Hawaii adds one carve-out, and it is specific to pets. If the landlord allows the tenant to keep a pet animal, the landlord and tenant may agree to a separate pet deposit to compensate for damage the pet may cause — and that pet deposit may itself be up to one month’s rent. So a tenant with an approved pet can face a combined ceiling of two months’ rent: one month as the ordinary security deposit and one month as the pet deposit. A tenant with no pet is capped at a single month. Verify the current cap before you set any deposit amount.

No Furnished-Versus-Unfurnished Split

Some tenants and landlords arrive from mainland states where furnished units carried a higher deposit ceiling. Hawaii draws no such line. The one-month cap applies whether the unit is furnished or unfurnished. The only lawful way to exceed one month is the separate pet deposit, and only when a pet is genuinely permitted.

Hawaii Revised Statutes section 521-44 lists the specific purposes for which a landlord may keep part of a security deposit. The landlord bears the burden of justifying each deduction, so anything not clearly on the list is presumed to be the landlord’s cost to absorb.

Permitted Deductions

• Unpaid rent and other defaults. Rent that remains owed, and other money defaults under the rental agreement.
• Damage beyond normal wear and tear. The cost to repair damage the tenant or the tenant’s guests caused, other than ordinary wear and tear — broken fixtures, large holes, or pet-stained flooring.
• Cleaning to move-in condition. The reasonable cost to return the unit to the level of cleanliness it had at move-in — not a blanket “make it spotless” charge.
• Wrongful-quitting damage. Damages that result when a tenant wrongfully quits the unit before the tenancy properly ends.
• Permitted-pet damage. Damage caused by a pet the landlord allowed, chargeable against the pet deposit and, if needed, the ordinary deposit.

Not Deductible — Ordinary Wear and Tear

Ordinary wear and tear is the natural deterioration that happens from living in a unit normally, and the landlord must absorb it. Hawaii treats these as non-deductible:

• Faded or lightly scuffed paint, and small nail holes from hanging pictures.
• Carpet worn thin along walkways from ordinary foot traffic, with no stains or pet damage.
• Minor marks, loose grout, or caulk that has aged around tubs and sinks in Hawaii’s humidity.
• Worn but still-functioning appliances and fixtures that simply reached the end of their useful life.

The deadline Hawaii landlords miss most often is the fourteen-day return rule. Under Hawaii Revised Statutes section 521-44, no later than fourteen days after the rental agreement terminates, the landlord must deliver two things: any remaining portion of the deposit, and — if any amount is kept — a written notice stating the particulars and grounds for the retention, including written evidence of the costs. The clock runs from termination of the tenancy, when the tenant surrenders possession.

What the Written Notice Must Include

The notice must describe each deduction, its amount, and the grounds for it, and it must attach the written evidence of the costs of remedying the tenant’s defaults — estimates, invoices, or receipts for materials, services, or cleaning. A bare figure with no backing is exactly the kind of deduction a tenant can challenge and win. The statute frames the notice as an evidentiary requirement, not a courtesy, so treat the supporting documents as mandatory rather than optional.

Proof of Mailing and the “Before Midnight” Rule

Hawaii gives landlords a clear safe harbor on timing. A return of the deposit or the furnishing of the written notice is presumptively on time if it is mailed to the tenant with acceptable proof of mailing and postmarked before midnight of the fourteenth day after termination, or if the tenant acknowledges receipt within the fourteen-day limit. In practice, that means you do not have to guarantee delivery by day fourteen — you have to get it into the mail, with proof, before the fourteenth day ends. Certified mail or another tracked method makes the postmark and proof easy to establish.

Hawaii keeps the holding rules simple. There is no statewide requirement to pay interest on a security deposit, and section 521-44 does not require the deposit to be held in a separate escrow account. Many Hawaii landlords hold deposits in a general account and pay no interest, which is entirely lawful. And unlike a number of mainland states, Hawaii has no county interest ordinance layered on top — the statute is the whole picture, so there is no “check your city” interest step here.

What Hawaii does not permit is a non-refundable deposit. A security deposit is refundable except to the extent the landlord may lawfully keep part of it for the purposes section 521-44 lists. A landlord cannot relabel the deposit — or a “cleaning fee” or “pet fee” collected as a deposit — as non-refundable to escape the return rules. Money taken as a deposit, including the separate pet deposit, must be accounted for at move-out and any unused portion returned within fourteen days.

Hawaii backs the deposit rules with two distinct penalties, and either one can dwarf the deposit itself.

Automatic Forfeiture for a Late Landlord

The first penalty is automatic. As covered above, a landlord who fails to furnish the required written notice and information within fourteen days after termination loses the right to retain any part of the deposit. This is not a discretionary sanction a judge weighs — it is written into the statute, and it applies even where the landlord could have proven real damage. The lesson is stark: a landlord with a legitimate deduction who simply mails the notice late can end up owing the tenant the entire deposit back.

Treble Damages for Wrongful, Wilful Withholding

The second penalty is a multiplier. Under Hawaii Revised Statutes section 521-44, if a landlord wrongfully and wilfully retains a security deposit, a court may award the tenant damages of up to three times the amount wrongfully withheld, plus the cost of suit and reasonable attorney’s fees. That treble exposure targets the landlord who keeps a deposit with no legitimate basis or refuses to itemize, not the one who makes a good-faith judgment call on a specific deduction.

Put the rules together and the Hawaii move-out becomes a repeatable checklist rather than a judgment call. Follow this sequence and penalty exposure all but disappears.

A thorough move-out record starts at move-in. Use a documented Hawaii security deposit return letter to deliver the written notice, and a clean Hawaii security deposit itemization form to keep the deductions organized and defensible.

Most deposit disputes never reach a courtroom, but when they do in Hawaii, they land in the small claims division of the district court — a forum designed to be used without a lawyer. Hawaii’s ordinary small-claims ceiling is five thousand dollars, but the Legislature has waived any dollar limit for a residential security deposit claim. That means a tenant can pursue the full deposit plus the treble multiplier in small claims even if the total tops the usual cap. Verify the current rules, which the Legislature adjusts over time.

The pattern is consistent: Hawaii deposit cases are won on paper and lost on the calendar. The landlord who documents condition at both ends, itemizes with written evidence, and mails on time rarely loses — and the tenant who keeps their own photos and a copy of the written notice is equally well positioned to recover a wrongful withholding.

Beyond a routine move-out, a handful of situations trip up Hawaii landlords because the deposit rules interact with other events. Three come up often.

When the Property Is Sold

If a landlord sells the rental while a tenant is in place, the security deposit does not simply vanish with the change of owner. The seller should either transfer the remaining deposit — after any lawful deductions — to the new owner and notify the tenant, or return the remaining deposit to the tenant with a full accounting. A buyer taking over an occupied Hawaii rental should confirm in escrow that deposits are accounted for and transferred in writing, because the successor landlord inherits the obligation to return the deposit at the end of the tenancy. Sorting this out at closing avoids a fourteen-day scramble later.

Roommates and a Single Deposit

Where several tenants share a lease and a single deposit, Hawaii treats the deposit as one sum tied to the tenancy, not as separate shares. When one roommate leaves and another stays, the landlord’s fourteen-day obligation is generally triggered only when the tenancy as a whole ends and the unit is surrendered — not each time one roommate moves out mid-lease. Splitting each roommate’s share of a refund is usually a private matter among the tenants. Landlords should return the single deposit to the tenants collectively unless the lease or a written agreement directs otherwise, and avoid being drawn into dividing it.

The Deposit Cap and a Rent Increase

The one-month cap is measured against the rent. If rent later rises, a landlord should not treat a permitted increase as a license to demand more deposit from a sitting tenant to “top up” to the new one-month figure for a deposit already lawfully collected. Landlords weighing an increase should review the separate rules that govern it — see our guide to Hawaii rent increase laws — and set the deposit correctly at signing rather than reaching for more later.

Every rule above ultimately turns on proof. Hawaii places the burden on the landlord to justify each deduction, which means the landlord who cannot document a charge loses it — regardless of whether the damage was real. Build the evidence file across the whole tenancy, not at the end.

At Move-In

• A written condition checklist, room by room, signed and dated by the tenant.
• Timestamped photos or video of every wall, floor, fixture, and appliance, stored where the date cannot be doubted.
• A written note of any pre-existing wear, so it is never later charged to the tenant.

During the Tenancy

• A dated log of every maintenance request and the landlord’s response, which also rebuts a habitability defense.
• Records of any lawful entry to inspect or repair, made with proper notice under Hawaii entry rules — see Hawaii landlord entry laws.

At Move-Out

• A second set of timestamped photos taken at surrender, to compare against move-in.
• Estimates, invoices, or a documented in-house cost for every charge, attached to the written notice.
• Proof that the notice and refund were mailed within fourteen days, postmarked before midnight of the fourteenth day.

The cheapest deposit dispute is the one that never happens. A few disciplined habits protect a Hawaii landlord across an entire portfolio.

• Document move-in exhaustively. A signed checklist and dated photos of every room create the baseline that decides every future deduction.
• Set the deposit at one month, and the pet deposit only where a pet is allowed. One month’s rent for the ordinary deposit, plus at most one more month as a separate pet deposit when a pet genuinely lives in the unit.
• Call it a deposit, and treat it as refundable. Never label a fee non-refundable; every dollar you collect as a deposit, pet deposit included, is refundable in Hawaii.
• Calendar the fourteen-day deadline at surrender and mail the notice with proof, postmarked before midnight of the fourteenth day.
• Attach the written evidence every time. The statute requires estimates, invoices, or receipts behind each deduction, so make them part of the notice by default.
• Screen carefully before you ever hand over keys. The tenants most likely to leave a unit in disputed condition are often the ones a thorough screening would have flagged.

That last point is where most disputes are actually won — before the lease is ever signed. A prior eviction, a pattern of damage, or unstable finances rarely appears out of nowhere; it usually leaves a trail an applicant’s history reveals. Screening for it is the single highest-leverage habit a Hawaii landlord can build.
