Nashua, NH Property Maintenance: Vacant Lot Maintenance (2026)

Nashua does not have a stand-alone 'vacant lot' chapter; vacant parcels are subject to the same general property-maintenance and right-of-way rules as occupied parcels. The primary authority is Chapter 182 (Housing Standards) Article V (Structural Standards), which requires that 'all exterior property areas shall be maintained in a clean and sanitary condition free from any accumulation of rubbish or garbage.' Accessory structures on a vacant lot must be 'maintained structurally sound and in good repair.' Vegetation overhanging or encroaching on streets or sidewalks is reachable under Chapter 285 (Streets and Sidewalks), which governs the public right-of-way. Illegal dumping on vacant private property is also reachable under the general littering provisions of the Nashua Revised Ordinances. There is no fixed weed-height number in Chapter 182 (such as the 12-inch rules some jurisdictions impose); enforcement is based on the accumulated-rubbish-or-garbage standard and the right-of-way obstruction standard. Zoning compliance for vacant parcels — including continuing-use, accessory-structure, and fencing rules — is administered through Chapter 190 (Land Use). Code Enforcement (603-589-3100) handles complaints. Enforcement is typically by written notice of violation with an opportunity to abate; persistent failure is enforceable under NRO § 1-12 (up to $1,000 per offense, each day a separate violation), and the City may pursue abatement through municipal-court action if the owner refuses to act.
