The state is telling a property owner in Kakaako to stop holding loud parties.
A concert was held last month, drawing hundreds of people to a parking lot between Kapiolani Boulevard and Waimanu Street that lasted into the early morning hours.
The event prompted dozens of complaints from nearby residents.
The Hawaii Community Development Authority sent a letter to inform the property owner, Henry Chang Trust, that a permit is needed to hold such an event.
Since a permit was never requested, the party was a violation and HCDA says fines may be posed if more parties are held.
