Hawaii's periodic-tenancy notice rule
Hawaii distinguishes monthly from shorter periodic tenancies. Under HRS § 521-21(d), a landlord may not increase month-to-month rent without 45 consecutive days' written notice before the effective date. Under subsection (e), a tenancy shorter than month-to-month requires 15 consecutive days' written notice.
The statute requires a writing but prescribes no special statewide form, additional content fields, or service method in the increase subsections. The clock runs to the effective date of the increase.
Amount, frequency, and fixed terms
Hawaii sets no general statewide percentage or CPI formula for the ordinary residential increase covered here. Section 521-21 also states no separate once-per-year frequency limit; the notice period must be satisfied for each covered increase.
The 45- and 15-day increase provisions address periodic tenancies. For a fixed term, § 521-21(a) permits the parties to agree on rent, and subsection (b) makes rent payable at the agreed time and place. Read the fixed lease and any adjustment provision rather than treating periodic-tenancy notice as a power to rewrite the agreed term.
Retaliation is a distinct protection. HRS § 521-74(a) bars a landlord from demanding an increase after the listed good-faith complaints or repair requests, subject to the exceptions in subsection (d). That is not a general amount cap on every increase.
Common questions
Is Hawaii's notice period 45 or 15 days?
It is 45 consecutive days for a month-to-month tenancy and 15 consecutive days for a tenancy shorter than month-to-month.
Does a large increase require more notice?
Not under § 521-21(d)-(e). The notice period changes with the tenancy's length, not the percentage increase. A local rule may differ.
Does Hawaii state special damages for short notice?
Section 521-21 states the notice condition but no rent-increase-specific damages amount. Retaliation and other contractual or statutory claims must be evaluated separately.
