Chelsea, MA Property Maintenance: Vacant Lot Maintenance (2026)

Vacant lot maintenance in Suffolk County is regulated under local nuisance and property maintenance ordinances backed by MGL c. 111, §123-132 (Boards of Health) and MGL c. 139 (buildings unfit for human habitation). Boston Code of Ordinances §16-12 (nuisances) requires property owners to keep grass and weeds under 10 inches, remove trash and debris, and prevent rodent harborage. Boston's Problem Property framework (§16-18.1) applies to chronically neglected vacant lots. Chelsea Code §9-110 requires mowing of vacant lots when vegetation exceeds 10 inches; the Department of Public Works may mow at owner expense after notice. Revere §7.12.010 similarly prohibits rank vegetation and accumulated debris, with DPW mowing authority. Winthrop Town Bylaws Chapter 9 and Board of Health regulations require grass and weeds under 12 inches and removal of trash. All four municipalities enforce fencing of open excavations (required under MGL c. 143, §2), removal of diseased trees that pose a hazard, and securing abandoned structures. Vacant properties with buildings must register under Boston Code §9-1.4, Chelsea equivalent, Revere §7.10, and Winthrop similar. Illegal dumping is prosecuted under MGL c. 270, §16 with fines up to $5,500 plus cleanup costs. Municipal abatement: after notice period (typically 7-30 days), the city may enter the lot to mow or clean up; costs attach as a lien on the property tax bill under MGL c. 111, §127B. Some Boston neighborhoods have adopted community garden programs for long-term vacant lots, providing an alternative use.
