What are construction hours in Nashua, NH?

Under Nashua Chapter 128 (Construction and Demolition Work), no construction or demolition is allowed in any residential zone (as defined in Chapter 190 Land Use Code) or within 600 feet of any dwelling unit between 8:00 p.m. and 7:00 a.m. Sunday through Friday, between 7:00 p.m. Saturday and 8:00 a.m. Sunday, or on Sundays and holidays at all. The 600-foot dwelling buffer is broad - most commercial corridors in Nashua sit within 600 feet of at least one home, so the practical citywide window is 7 a.m. - 8 p.m. weekdays, 7 a.m. - 7 p.m. Saturdays, and no Sunday/holiday work. Emergency work directed by the Code Enforcement Director and Public Works-authorized work are exempt. Violations are a fine not less than $100 per Chapter 128.

How do I report construction noise outside permitted hours in Nashua?

Call the Nashua Police Department non-emergency line at 603-594-3500 - Police have primary enforcement responsibility for Chapter 128. The Director of the Code Enforcement Department (603-589-3330) and the Zoning Administrator also have authority to enforce, which is useful for documenting a pattern at an active construction site during business hours. Confirm whether the work is within 600 feet of any dwelling unit (almost all Nashua construction is) and outside the permitted window. Even within permitted hours, unreasonable or excessive construction noise is citable under Chapter 201 (Noise) and NH RSA 644:2 disorderly conduct.
