Citations begin November 2025🏠 HOA Rules During Restrictions
Maryland Code §11B-111.3 prohibits HOAs from enforcing lawn appearance standards that would require homeowners to violate utility-declared water shortage conditions affecting the county. WSSC's Level 2 Alert qualifies as the triggering declaration for Montgomery and Prince George's counties.
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 current restriction order from WSSC Water. 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
WSSC serves 1.8 million customers across Montgomery and Prince George's counties, the 9th largest water utility in the US. The primary supply is the Potomac River via the Great Falls intake; backup storage comes from Triadelphia and T. Howard Duckett reservoirs. Potomac River flow at Little Falls ran 22% below the 10-year April average as of early 2026. Duckett Reservoir is at 54% of capacity, triggering Level 2 Alert in November 2025. Montgomery County has grown 8% since 2019, adding stress to existing supply infrastructure.
This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Rockville area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.
