Chelmsford, village by village
A 1960s suburb built around five old villages
Chelmsford's housing is mostly detached single-family homes, and the 1960s alone account for nearly a quarter of it. The town's housing plan reported that 54% of occupied homes were built before 1970 (Affordable Housing Plan, 2008 data).
Chelmsford Center
With South Chelmsford, home to most of the town's high-style early houses, many still lived in. A local historic district covers the center; ask the Historic District Commission before exterior work.
North Chelmsford
The old mill village on Stony Brook, now Vinal Square's renovated mill complexes, with multifamily housing along Middlesex Street and Tyngsborough Road. Served by its own water district.
South Chelmsford
A small historic farm village along Route 27 and Maple Road, with a garrison house from about 1690.
West Chelmsford
A nineteenth-century scythe-factory and mill village that is now mostly single-family homes.
Eastern Chelmsford and the Westlands
The side of town closest to Lowell, where most new suburban settlement went between 1915 and 1940. Lake and pond areas have small cottages, most converted to year-round homes.
Village histories draw on the Massachusetts Historical Commission's Chelmsford survey report and the town's Master Plan.
Water, sewer and septic
Three water districts, limited sewer capacity and new septic rules
Chelmsford's water comes from three independent districts: the Chelmsford Water District, the North Chelmsford Water District and the East Chelmsford Water District, each with its own rules (Water Districts). Wastewater from sewered homes goes to the Greater Lowell treatment plant.
Service lines. The North Chelmsford Water District received a "no-lead-service" designation after MassDEP accepted its final inventory on September 23, 2025, and its rules make the owner responsible for repairs between the property line and the meter (2025 water quality report, district rules). The Chelmsford Water District publishes its inventory as an online map (Service Line Inventory) and says most household lead comes from a home's own plumbing (Lead in Drinking Water).
PFAS. The Chelmsford Water District reported PFAS6 above the state limit in three quarters of 2025 and has broken ground on a carbon treatment plant at Crooked Spring (2025 water quality report).
Sewer connections. A sewer capacity and connection restriction has been in effect since November 1, 2022, most recently updated September 14, 2026: no new connections or added flow for changed or expanding properties, no sewer for detached accessory apartments, and a narrow review path for failed septic systems (sewer restriction). Where connections are allowed, they need a written permit and a town-licensed drainlayer, and foundation drains, downspouts and other groundwater sources may not connect to the sewer (Sewer Use Regulations). After heavy rain in 2024 pushed the town's sewer flow above its permitted level, the town started a pilot offering homeowners incentives to disconnect sump pumps from the sewer (2024 Annual Town Report).
Grinder pumps. Grinder pump units belong to the homeowner. The town covers out-of-warranty units through its contractor, but not damage from misuse, and grease removal is the homeowner's job (Grinder Pumps).
Septic. The Board of Health's Article XIX, effective February 3, 2026, requires pumping on a schedule set by the system's age and aquifer zone, yearly pumping for any home with a garbage disposal, and inspections every three to four years (Article XIX). No excavation or construction of a septic soil absorption system is allowed from November 30 to April 1 (Septic Process).
Permits and local rules
Plumbing and gas permits in Chelmsford
In Chelmsford, plumbing and gas permits come from the Building Department and are filed online through the town's PermitEyes system; the plumbing, gas and electrical inspectors hold office hours weekday mornings (Procedures for Obtaining a Permit).
Fees. The town's fee page lists a hot water tank permit at $50, residential plumbing and gas at $75 for the first fixture plus $6 for each additional fixture, sewer-related work at $50, irrigation at $75 and a possible $100 reinspection fee (Permit Fees). New irrigation systems also need DPW approval and, in the Chelmsford Water District, a district permit, backflow device and rain sensor (Irrigation Information).
Who pulls it. Under state rules, plumbing and gas permits are issued only to licensed plumbers and gas fitters, and work can't start until the permit is issued (248 CMR 3.05). Check a license on the state license lookup.
Last verified November 2026. New England Plumbers is a referral service. We don't pull permits or do plumbing work. The contractor who does the job handles the permit.
FAQ
Chelmsford plumbing questions
Which water district serves my Chelmsford home?
It depends on where you live: the Chelmsford Water District, the North Chelmsford Water District or the East Chelmsford Water District. The town posts a water districts map and asks residents to contact the district for their area. Each district has its own rules.
Can I connect my house to the Chelmsford sewer?
Possibly not right now. A sewer capacity restriction has been in effect since November 1, 2022 (updated September 14, 2026) because flows may exceed the town's capacity under its agreement with Lowell. Detached accessory apartments can't connect, and a failed septic system qualifies for review only if it's at least 20 years old and in an aquifer protection zone.
How often do I have to pump my septic system?
Under the Board of Health's Article XIX, effective February 3, 2026, it depends on the system's age and whether you're in a high-aquifer area, from every four years down to every year. Any home with a garbage disposal must pump every year, and inspections are required every three to four years.
Do I need a permit for a lawn irrigation system?
Yes, more than one. In the Chelmsford Water District you file a $50 district irrigation permit and need a backflow device, a rain sensor and a district inspection within 30 days; the town also requires an irrigation plumbing permit, with DPW approval first.
Is there a charge to use New England Plumbers?
No. The call and the referral are free to homeowners. Any estimate and any work are agreed directly between you and the contractor.
