Fines & Enforcement

🏠 HOA Rules During Restrictions
HOAs cannot enforce lawn-appearance standards that would require homeowners to violate active municipal water ordinances. Document compliance if your HOA sends a violation notice.
If your homeowners association sends a violation notice for a dormant or brown lawn during the current restriction period, respond in writing citing the applicable law and include a copy of the Hawaii County Department of Water Supply's current restriction order. Most HOAs will rescind the notice once they are made aware of the legal protections in place. If the issue persists, contact your county’s code enforcement division for assistance.

This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Hilo area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.
