Pearl City cannabis home cultivation is permitted only for registered medical patients under HRS 329-122 at up to ten plants. Active-duty military face additional federal prohibitions beyond state law.
Cannabis home cultivation in Pearl City is governed exclusively by state HRS 329-122, with no corresponding Honolulu ROH ordinance. Qualifying patients holding a Hawaii 329 registration card, and a narrow set of caregivers limited since January 2024 to serving minors or incapacitated adults, may cultivate up to ten plants at one registered grow site located at a residence or site under their control. Each plant must be tagged with the 329 card number and expiration. Inter-island transport is prohibited. Recreational cultivation remains illegal statewide. Active-duty service members at JBPHH remain subject to federal Controlled Substances Act and UCMJ regardless of state law, including in off-base Pearl City housing.
Unauthorized cultivation is a state criminal offense with penalties scaling by plant count. Service members face additional UCMJ exposure. Overages can cancel 329 registration.
