Newton, MA Landscaping Rules: Weed Ordinances (2026)

Sec. 5-22 defines 'a condition of overgrown vegetation' as weeds, grass, bushes or other shrubbery so untrimmed or unkempt that it creates a reasonable expectation of harboring or attracting rats and vermin, or of concealing pools of stagnant water, rather than setting a bare height limit in inches. That condition becomes a public nuisance under Sec. 5-22(b) once it is visible in public view, meaning visible from a public way or from multiple neighboring properties, for more than 60 days, and it also causes adverse health or safety effects on neighbors, materially diminishes a neighboring property's reasonable use and enjoyment, or creates a hazardous or harmful condition.

The Commissioner of Inspectional Services or a designee enforces the standard the same way it enforces the junk-and-debris half of the section: a written notice describing the overgrown condition, a 30-day window under Sec. 5-22(f) to cut it back, and, if unresolved, a climbing daily fine under Sec. 5-22(g) of $100 for the first week, $200 for the second week and $300 a day after that. The Commissioner also has standing authority to write further rules and regulations implementing the vegetation standard, and both the notice and fine mechanics apply lot by lot in any residential district, not just to vacant parcels.
