Actually unless your lease or contract prohibits it you are. You can carry on any private property you have consent to be on.
Hawaiis place to keep and carry laws are unconstitutional and wouldent stand up to any level of scrutiny.
I can open or conceal carry per 134-23
"Except as provided in section 134-5, all firearms shall be confined to the possessor’s place of business, residence, or sojourn;"
HRS 134-5 refers to hunting.
It will cost a lot of money and guns to fight our few crooked cops, when they bust you at a place of "business, residence, or sojourn".
The guys here will arrest you, take your guns( never give them back), just to run you through the system
and prove a point, even though you won't be prosecuted. Yes the laws here are un-constitutional, but some of our cops are not ethical
and they know you will be dead or moved on long before you win in court, because it takes years and years to get through the courts.
As long they get to go home and get their retirements they could care less about your rights and indeed your life.
Plus they will enjoy the Les Baer 1911 45 they confiscated as evidence.
