Citations begin Permanent since 2012🏠 HOA Rules During Restrictions
Illinois CICAA requires HOAs to accept municipal ordinances. Naperville's permanent ordinance takes precedence.
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 Naperville Water Utilities'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.
Why These Restrictions Exist
Naperville draws from Lake Michigan via the DuPage Water Commission. Lake Michigan levels are near normal. The permanent ordinance exists for peak-demand management.
This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Naperville area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.
