Lowell's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In Lowell, Massachusetts, there are 8 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Native Plants

Native plants, pollinator gardens, and naturalistic landscapes are fully allowed in Lowell provided they are maintained and do not create a nuisance. The city encourages native plantings for stormwater and habitat benefits along the Merrimack River corridor.

Key details: Native plantings: Allowed and encouraged. Design standard: Must look intentional. Historic districts: Extra design review. Riverfront: Natives often required. Invasives: Discouraged.

Contact your local code enforcement office for specific penalty information.

The rules around native plants in Lowell lean permissive, but that does not mean anything goes.

Rainwater Harvesting

Rainwater harvesting with rain barrels or cisterns is legal and encouraged in Lowell. Small residential systems used for irrigation are unregulated, while larger indoor-use systems must comply with the Massachusetts Plumbing Code.

Key details: Rain barrels: Legal and encouraged. Outdoor use: Unregulated at the tap. Indoor plumbing: 248 CMR 10.00 applies. Potable use: Effectively prohibited. Green infra: Supported for stormwater.

Contact your local code enforcement office for specific penalty information.

If you are coming from a city with tighter rules, you will find Lowell gives residents more flexibility on rainwater harvesting.

Artificial Turf

Artificial turf is not banned in Lowell for residential use, but installations may face stormwater review and historic-district design review. Some Massachusetts communities have moved to restrict turf, and state PFAS concerns may affect future rules.

Key details: Residential turf: Generally allowed. Stormwater: Drainage review possible. Historic districts: Design review required. PFAS concerns: Statewide trend. Infill: Organic preferred.

Water Restrictions

Lowell has no year-round watering ban, but Code of Ordinances Chapter 272, Part 5 (Restrictions on Use of Water, sections 272-101 through 272-106) lets the Lowell Regional Water Utility declare a state of water supply conservation and impose odd/even-day watering, watering hours, a full outdoor watering ban, pool-filling bans, or a ban on automatic sprinklers. Massachusetts state law (MGL c. 40, sec. 41A) independently authorizes water authorities to restrain water use during a declared drought emergency.

Key details: Code Section: Lowell Code Ch. 272, Part 5, sec. 272-103. Declaration authority: Lowell Regional Water Utility (sec. 272-102). Typical schedule: Odd/even-day watering (commonly May 1-Sept. 30). State authority: MGL c. 40, sec. 41A (drought emergency). First-violation fine: $50; $100 each subsequent (per day).

Under the Lowell ordinance, any person violating Part 5 is liable to the City for $50 for the first violation and $100 for each subsequent violation, recoverable by indictment, by complaint before the District Court, or by noncriminal disposition under MGL c. 40, sec. 21D, with each day of violation a separate offense.

Tree Removal & Heritage Trees

Removing a public shade tree in Lowell requires action by the tree warden and, under MGL c. 87, sec. 3, a posted and published public hearing with at least seven days' notice; no abutting owner may remove such a tree on their own. Removing vegetation on private property may also require a Conservation Commission permit under Lowell Code section 227-3(L).

Key details: Code Section: MGL c. 87, sec. 3; Lowell Code sec. 227-3(L). Public shade tree removal: Tree warden permit plus public hearing. Notice: Posted and published at least 7 days before hearing. Private vegetation: Conservation Commission permit may be required. Penalty: Up to $500 for injuring a public tree (sec. 12).

Cutting down or removing a public shade tree without a tree warden's permit and hearing violates MGL c. 87, sec. 3 and is punishable under MGL c. 87, sec. 6; willful injury or destruction of a public tree carries a fine of up to $500 under MGL c. 87, sec. 12. Removing protected vegetation without a required Conservation Commission permit can trigger enforcement orders and fines under the Wetlands Protection Act.

Compared to other cities, Lowell takes a harder line on tree removal & heritage trees. The enforcement and penalty structure reflects that.

Weed Ordinances

Lowell Code section 171-12 (Weeds and Noxious Matter), in the Health and Sanitation chapter, bars owners from allowing weeds or other noxious matter on their lot or abutting sidewalk and authorizes the Board of Health to order abatement, with a $50 fine per offense. A separate property-maintenance rule (sec. 227-3L) caps weeds at 18 inches and declares overgrowth a public nuisance.

Key details: Code Section: Lowell Code sec. 171-12 (Weeds and Noxious Matter). Enforcing body: Board of Health (Ch. 171) and Development Services (Ch. 227). Abatement: City may cut/remove and bill the owner. Sec. 171-12 fine: $50 per offense. Sec. 227-4 fine: $100 per offense, each day separate.

Violation of the section 171-12 weed prohibition is punishable by a fine of $50 for each offense, and the Board of Health may abate the condition and recover the cost. Violations of the Chapter 227 overgrowth standard carry a $100 fine per offense under section 227-4, each day a separate offense.

Grass Height Limits

Lowell Code of Ordinances section 227-3(L) (Overgrowth) makes it unlawful to allow weeds to reach 18 or more inches on any developed lot, or within 150 feet of a building, street, sidewalk, or right-of-way on an undeveloped lot, and declares such growth a public nuisance. Violations carry a $100 fine per offense under section 227-4, with each day a separate offense.

Where it applies: Developed lots; within 150 ft of a building/way on undeveloped lots. Status: Declared a public nuisance. Penalty: $100 per offense (sec. 227-4), each day separate.

Any person or owner who violates Chapter 227, Article I is subject to a fine of $100 for each violation under section 227-4, with each day or part of a day the violation continues constituting a separate offense, enforceable by noncriminal disposition under MGL c. 40, sec. 21D. The City may also cut or remove the offending growth and recover its costs.

Tree Trimming

In Massachusetts, trees within or along a public way are public shade trees that may not be cut, trimmed, or removed by anyone except the tree warden or under a written permit from the tree warden, even by the abutting property owner, under MGL c. 87, sec. 3. Lowell's own Code (sec. 227-3L) separately requires owners to trim hedges, shrubs, and trees so limbs do not obstruct streets or sidewalks and to remove dead limbs that could fall onto a public way.

Key details: Code Section: MGL c. 87, sec. 3; Lowell Code sec. 227-3(L). Public shade trees: Permit from tree warden required to cut/trim/remove. Public hearing: Required to remove a public shade tree (7-day notice). Private overhang rule: No limbs obstructing street/sidewalk; remove dead limbs over a way. Damage penalty: Up to $500 (MGL c. 87, sec. 12).

Cutting, trimming, or removing a public shade tree without a tree warden's permit violates MGL c. 87, sec. 3 and is punishable under MGL c. 87, sec. 6; willfully injuring a public shrub, plant, or tree carries a fine of up to $500 under MGL c. 87, sec. 12. Failure to abate a privately owned tree or hedge overhanging a public way under Lowell Code sec. 227-3 is subject to the property-maintenance penalty in sec. 227-4 (a $100 fine per offense, each day a separate violation, enforceable by noncriminal disposition).

This is one of the stricter rules in Lowell's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
