Hawaii HRS § 521 — Security Deposit + Notice Rules Most Landlords Miss

Hawaii has a URLTA framework under HRS § 521 that is unusually tenant-protective for a non-mainland market. The deposit cap is one of the strictest at one month's rent. The 14-day return deadline is among the shortest. Rent-increase notice on month-to-month tenancies is 45 days — one of the longest in the US. Source-of-income discrimination is prohibited statewide. Hawaii-based operators rarely run into multi-state confusion, but mainland operators expanding into Hawaii routinely under-comply on every one of these.

The 1-month deposit cap

HRS § 521-44 caps the deposit at one month's rent. Pet deposits may be charged separately under specific conditions — verify the current text of § 521-44 before structuring a pet-related charge. The general one-month cap is strict and applies to all standard residential tenancies.

The 14-day deposit return

HRS § 521-44 requires the landlord to return the deposit, less any lawful deductions, within 14 days after termination of the tenancy. Send the balance plus an itemized statement to the tenant's forwarding address.

The 14-day window is among the shortest in the US (only New York's 14-day post-HSTPA matches it, with Massachusetts' 30 days and the typical 30-day window elsewhere). Operators who run multi-state portfolios often default to 30 days — in Hawaii this is two weeks too late.

Bad-faith retention

Failure to comply with the 14-day return + itemization rules exposes the landlord to forfeiture of the deposit plus additional statutory damages. The deposit becomes refundable in full if the itemization is missing, regardless of how clear the damage was.

The 45-day rent increase notice

HRS § 521-21(d) requires 45 days written notice for any rent increase on a month-to-month tenancy. This is among the longest notice windows in the US — only Maine (45 days, going to 75 for increases of 10% or more) and Oregon (90 days statewide under SB 608) require more.

The 45-day window applies regardless of the amount of the increase. There is no carve-out for small increases or for buildings exempt from the cap (because Hawaii has no statewide cap). The notice itself just needs to identify the new rate and the effective date.

Habitability and entry

HRS § 521-42 imposes URLTA-style habitability obligations: comply with applicable codes, supply running water, heat, electricity, and maintain common areas.

HRS § 521-53 requires at least 2 days notice for non-emergency entry. This is the URLTA-norm 48 hours but framed as 2 days; the practical effect is the same.

Source-of-income protection

The Hawaii Fair Housing Law prohibits discrimination on a broad list of categories including source of income. Statewide. Refusing Section 8 vouchers, treating voucher applicants differently in screening, or advertising "no vouchers" creates fair-housing exposure regardless of the property's geography within the state.

Other required disclosures

• Federal Title X lead-paint disclosure for pre-1978 properties.
• Identification of the owner or authorized agent.
• General excise tax (GET) number for the rental — Hawaii-specific.

The GET number disclosure is occasionally missed by mainland operators. Hawaii operates a general excise tax rather than a sales tax, and rental income is subject to it. Operators must register, collect, and remit GET; the registration number is a disclosure item on the lease.

Eviction notice (for completeness)

HRS § 521-68 requires a 5-day written notice to pay or quit for non-payment of rent. Material breach gets a 10-day notice with right to cure under § 521-72. No-cause termination of a month-to-month tenancy requires 45 days written notice (HRS § 521-71) — unusually long among URLTA states.

Compliance checklist

For every Hawaii rental:

1. One-month deposit cap. Pet deposits separate under § 521-44 conditions.
2. Federal lead disclosure for pre-1978 properties.
3. Owner/agent identification in the lease.
4. General excise tax (GET) number disclosed on the lease.
5. Move-in inspection with photos.
6. 14-day deposit return + itemized statement after termination.
7. 45-day rent-increase notice on month-to-month tenancies.
8. 2-day entry notice discipline.
9. 45-day no-cause termination notice for month-to-month tenancies.
10. Source-of-income compliance in screening criteria.

How Proprietio handles Hawaii leases

Proprietio's Hawaii-tier lease template includes the § 521 disclosures, the GET number field, the 1-month deposit cap, and the 2-day entry notice clause. Rent-increase workflow defaults to 45 days; termination workflow flags the 45-day rule for no-cause month-to-month. The 14-day deposit return clock is tracked with reminders 3 days and 1 day before expiry.

Hawaii's combination of strict cap, fast return, long notice, and SOI protection is unusual for a small-market state. Mainland operators expanding to Hawaii benefit from treating it as a deliberate compliance discipline rather than an extension of California or Washington defaults.
