🏠 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 Pennichuck Water Works'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

Pennichuck Water Works serves Nashua and surrounding communities. Contact the utility directly at https://pennichuck.com for current stage status and restriction details.

Rainfall Deficit: See Pennichuck Water Works for current deficit data
