Landlords in Hawaii may only enter without permission when an emergency threatens the safety on the unit’s inhabitants. Otherwise, they must provide 2 days of advance notice when they intend to enter the unit to show the space to a prospective renter or make a repair. A Hawaii landlord may also only enter at a “reasonable” time, which can be defined within the terms of an applicable lease agreement.
