Hawaii Rent Increase Notice

What Hawaii law says

• The 2017 HRS Chapter 521 compilation says rent cannot be increased in a month-to-month tenancy without 'written notice given forty-five consecutive days prior to the effective date of the increase' (521-21(d)).
• For tenancies shorter than month-to-month, the notice period is fifteen days (521-21(e)).
• The text we read includes amendments only through 2015, so later changes are not confirmed.
• The DCCA page we read does not address rent increase notice or a statewide rent cap.

Steps for a landlord

• Give written notice 45 consecutive days before the new rent.
• Confirm no later amendment changed the period.
• Check the lease for fixed-term rent terms.
• Keep proof of the notice date.

What to put in the notice

• The tenants' names and the rental address
• The current rent and the new rent
• The date the new rent starts, after the required notice period
• The date of the notice and how it was delivered
• Your name and signature

Things to watch

• The version read is older; check current HRS 521-21 or an attorney.
• The pages we read do not say what applies to fixed-term leases.
• Cities and counties can add their own rules, including rent control and extra notice requirements. Check your local rules too.
