Watertown, MA · About 3 mi from our Waltham shop
Two-families, tight lots and the Charles. We know Watertown.
Watertown was the first community in Massachusetts to adopt the Specialized Stretch Code, so new homes and big additions here are built to the state's toughest energy standard. Our customers here have had us redo kitchens and baths and even raise the pipes in a low basement ceiling.
How Watertown jobs go
A small city with its own rulebook
Watertown is a compact city on the Charles where only about one home in six is a detached single-family house (U.S. Census, ACS 2019-2023). The zoning ordinance even spells out that two units joined side by side on a shared wall count as a two-family, which matters when we plan work on one half of a house.
What surprises people is how much of the process runs through the DPW. A new house, a conversion from one unit to two, a new driveway or a sump pump with an infiltration system can each need a DPW stormwater permit or a street opening permit before the building permit is any use.
Close to the river, Watertown's own wetlands ordinance reaches farther than the state rule: a 150-foot buffer instead of 100. We check the Conservation map before we price any work on a lot near the water.
Watertown reviews
What Watertown customers said
One Watertown homeowner had us do a bathroom and the kitchen, then called us back for a second bathroom. Both reviews below are from Watertown; the photos are from jobs around Greater Boston.
“I am so glad I chose HouseCraft. I found everyone to be knowledgeable, reliable, innovative and hardworking. There were things you did that others said were impossible to do, like raise the ceiling pipes in my basement. Your prices are very reasonable and working with all of you was such a pleasure. The bathroom and kitchen are fantastic! I liked their work so much I had them renovate another bathroom and it is beautiful.”
Rita B. · Watertown, MA “The guys were quick and professional. Reasonable price. I love the way everything looks. Thank you HouseCraft.”

Local rules
Permits and reviews particular to Watertown
Gathered from the Watertown city website and the state's energy code list. Your permit review is where the city confirms which of these apply.
Demolition delay, 50-year threshold
Proposing to demolish all or a substantial part of a Watertown building 50 or more years old starts a two-step Historical Commission review: a preliminary look by the Chair and one member, then a public hearing if needed. If the Commission finds the building significant and worth preserving, it can delay demolition for up to 24 months.

Mount Auburn Street Historic District
Inside the Mount Auburn Street Historic District, the Historic District Commission reviews exterior architectural features visible from a public way and can prevent demolitions and inappropriate alterations.
150-foot wetland buffer
Watertown's wetlands ordinance sets a 150-foot buffer zone around resource areas, wider than the state's 100 feet, and the area within 200 feet of a perennial river is itself protected. Work there may need a Notice of Intent with the Conservation Commission.
DPW stormwater permit
DPW Engineering requires a stormwater management and erosion control permit for projects such as converting a single-family to a two-family, building a new one- or two-family home, adding 500 square feet or more of net impervious surface, or installing a sump pump with a subsurface infiltration system.

Street opening permit and winter ban
Excavation for new laterals or utilities, driveway paving, and storing dumpsters or materials in the public right-of-way all need a street opening permit filed by the contractor. Watertown bars street openings from November 15 to April 15 unless the Superintendent of Public Works allows an exception.

Health Department demolition plan
Before demolition, Watertown's Health Department wants a plan for noise, odor, dust and rodent control, plus an affidavit from a certified asbestos inspector that asbestos was removed under state rules or was not present.

Specialized Stretch Code
Watertown says it was the first municipality in Massachusetts to adopt the Specialized Stretch Code, in January 2023; the state's list shows it in effect from July 1, 2023. New homes and major additions are built to that standard.
What needs a building permit
Watertown's Inspectional Services says most work on or in a structure needs a building permit. Its listed exceptions include minor repairs, painting, sheds under 200 square feet and retaining walls under 48 inches high.

Questions
Common Watertown questions
Who files the street opening permit in Watertown?
The contractor doing the excavation does, not the homeowner. Watertown requires the contractor's insurance certificate naming the city, a permit bond and a Dig Safe confirmation number.
Does my Watertown sump pump need a permit?
Installing a sump pump with a subsurface infiltration system needs Watertown's stormwater management and erosion control permit from DPW Engineering. We include that filing when a basement job adds one.
