Permits
Permits and rules for basement work in Westford
Westford's Building Department is at 55 Main Street. Its permit table lists renovations and remodeling, windows and doors, additions, and insulation and weatherization. The online portal handles electrical, plumbing, gas, roofing, windows, doors, siding and insulation permits, and since December 2023 kitchen and bath remodels; other permits must be submitted in person or by mail, which appears to include a basement renovation (Building Department; permit portal). The building official has 48 hours to inspect, and the final inspection closes out the permit.

Fees. The town's fee page says the minimum fee for every building permit is $50, with no refunds once paid (Permit Fees). The fee schedule PDF still posted is marked effective March 1, 2004; it lists re-inspections at $80 each and a triple fee for work started without a permit (Fee Schedule). Ask the department for the current rate on your job.
What the state code requires. The state code requires a permit to substantially cut away a wall or cut a beam or load-bearing support, and exempts only ordinary repairs (780 CMR R105); its guidance chart marks the structural carpentry, insulation and wallboard of a finished basement as permitted work (state HIC chart). A habitable basement room needs a ceiling of at least 6 feet 8 inches, and a single- or double-hung escape window needs a 3.3 square foot net clear opening under the state amendment (780 CMR chapter 3). The state code also says lots must be graded to drain surface water away from foundation walls (780 CMR R401.3).
Choosing a contractor. Home Improvement Contractor registration is generally needed for work on owner-occupied homes of one to four units; check it on the Contractor Hub. A licensed construction supervisor or registered design professional must oversee construction on one- and two-family homes (construction supervisor rules). Contracts over $1,000 must be written and include the contractor's registration number, start and completion dates and payment schedule (M.G.L. c.142A §2). An engineer isn't required by state code for foundation repair as such, but the building official can ask for more construction documents, and they must be sealed by a registered design professional in a flood hazard area (R107.1 and R322.1). On a ledgy lot, exterior work still counts as excavation: Dig Safe needs at least 72 hours' notice, weekends and holidays excluded (M.G.L. c.82 §40A).

Water
Where the water comes from in Westford
No sewer to tie into. Westford's 2010–2015 Open Space and Recreation Plan says the town has no public sewer service and every home depends on private on-site wastewater disposal (2010–2015 Open Space and Recreation Plan). `We didn't find` (this deletes the septic-regulation clause and keeps the rest of the sentence: "We didn't find a rule on sump discharge for septic homes, so ask the Board of Health before the line is placed.") a rule on sump discharge for septic homes, so ask the Board of Health before the line is placed.
The storm drain bylaw. Chapter 82 of the General Bylaws, effective August 5, 2008, bans non-stormwater discharges to the town storm drain system and bans illicit connections even if they were once permissible. It exempts water from exterior foundation drains and footing drains, not including active groundwater dewatering, and from crawl space pumps, as long as they aren't significant sources of pollutants. Sump pumps and roof drains aren't named. Non-criminal fines run $100, $200 and then $300 per offense (Chapter 82).
Rock and slow till. The open space plan says rock outcroppings occur throughout town, that glacial till may only thinly cover bedrock between outcrops, that Hollis soils are shallow over bedrock, and that till transmits water slowly. Some Freetown Muck soils have a water table at or near the surface most of the year. The 2009 Comprehensive Master Plan says the Chelmsford Granite underlies much of the northern third of town (2009 Comprehensive Master Plan).
Stony Brook
The town's principal watercourse, with floodplain along it.
The northern third
Underlain by Chelmsford Granite, visible in outcrops, quarries and road cuts.
Snake Meadow, Millstone and Oak Hills
Named in the open space plan for large areas of rock outcrops.
Flood maps. Westford's Floodplain Overlay District covers the 100-year floodplain and floodways on FEMA's maps; as of the 2010–2015 open space plan those boundaries were based on maps dated June 15, 1983, and the plan expected flood boundaries in the northeast to move upgradient over time. Check your address on FEMA's Flood Map Service Center for the current map.
Wetland limits. The local Wetland Protection Bylaw puts work within 100 feet of wetland resource areas and 200 feet of perennial streams before the Conservation Commission (Wetlands and Permitting). The regulations, effective December 9, 2020, measure from the wetland edge: on a lot with an existing structure and artificial surface, a 30-foot limit of work and a 55-foot limit of building; otherwise 50 and 75 feet (Wetland Rules and Regulations). A curtain drain or regrading job near a wetland starts with that office.
Westford's homes
Six historic villages and the houses between them
The open space plan describes Forge Village workers' housing from the mid-19th to the early 20th century, Graniteville housing from the mid-19th to the mid-20th century, and Westford Center as an exceptionally well-preserved collection of 19th- and early 20th-century houses (2010–2015 Open Space and Recreation Plan).
The 2009 Master Plan counts six historic villages, all but Nabnasset on the National and State Registers (2009 Comprehensive Master Plan). We didn't find a local review requirement for exterior work near foundations, and the town plans we read don't record housing ages or foundation types, so a contractor should see the foundation in person. Homes built before 1978 need a licensed lead-safe renovation contractor when painted surfaces will be disturbed (lead-safe renovation).
Radon
Radon in Westford basements
We have no Westford radon number; the state's town dashboard didn't load for us. Massachusetts requires new one- and two-family homes in Middlesex, Essex and Worcester counties to include a passive radon mitigation system, and publishes town-level test results on its residential radon tracking page. State health guidance we checked in November 2026 says to test at the lowest livable level from November 1 to March 31 and re-test if the first test was in summer; it strongly recommends mitigation at 4.0 pCi/L (testing your home for radon).
FAQ
Westford basement questions
Where can a foundation drain discharge in Westford?
Westford has no public sewer, so the question is the yard or the storm drain. The town's storm drain bylaw, effective August 5, 2008, exempts water from exterior foundation drains, footing drains and crawl space pumps if it isn't a significant pollutant source, but not active groundwater dewatering. Sump pumps aren't named, so check with the town before tying into a street drain.
What are the fines for an illegal storm drain connection?
Under the same bylaw, non-criminal fines are $100 for a first offense, $200 for a second and $300 for each after that; a criminal fine can reach $300 a day. Connections are banned even if they were once allowed.
Can I file a basement renovation permit online?
Probably not. Westford's online portal takes trade permits, roofing, windows, siding, insulation and, since December 2023, kitchen and bath remodels and in-footprint deck repairs; the town says permits not on its list must be submitted in person or by mail.
How close to a wetland can basement drainage work go?
Westford's wetland regulations, effective December 9, 2020, set the limit of work at 30 feet from the wetland edge for an existing structure on an artificial surface and 50 feet in other cases, with limits of building at 55 and 75 feet.
What does it cost me to use New England Basement Pros?
Nothing. Asking is free for homeowners; the contractor prices the job, and the price and contract are between you and them.
