Georgetown, Massachusetts
Renovating in Georgetown, where the brooks and the Board of Health set the limits
- Georgetown Center (Routes 97 and 133)
Georgetown was Rowley's West Parish before it was a town, and most of its houses are newer than 1950. On those houses the limits come from the Board of Health, which counts bedrooms as total rooms divided by two, and from the brooks: land within 1,000 ft of the named ones sits in a Water Resource District with tighter septic and coverage limits. We work both out before anything is drawn.

The houses of Georgetown, era by era
Farmers settled along Penn Brook by the mid-1600s, and the West Parish village came to be called New Rowley. Small mills and later a shoe company built it up, and it incorporated as Georgetown in 1838. Today it is mostly residential and laced with brooks, with Pentucket and Rock Ponds, the Georgetown-Rowley State Forest and the Crane Pond Wildlife Management Area. I-95 runs through the eastern half. The town runs its own light and water departments but lists no sewer department, and its Board of Health writes the rules for on-site septic.
1680–1725
First Period houses, 1680s–1725
They survive along the old roads. The Hazen-Kimball-Aldrich House on East Main Street dates to the late 1600s or early 1700s, depending on the source. The Adams–Clarke House on West Main Street, about 1725, mixes First and Second Period features. The Dickinson–Pillsbury–Witham House on Jewett Street stands with an 18th-century barn on almost nine acres. Any building 75 years or older on the Historical Commission's inventory can face a six-month demolition delay, and the bylaw reaches partial demolition, so taking off an ell for an addition starts with the Commission. For partial work it can let the project proceed if the building's significance is not materially diminished.
1800s
Village houses of the 1800s
Through the later 1800s the population sat near 2,000, and it dipped below that in the early 1900s, so the town grew slowly for a long time. Every house from those years is past the 75-year line in the demolition-delay bylaw. Houses of that age often still have plaster and lath, and some are balloon framed, with studs running past the floors; when we open those walls, fire blocking goes in at each floor line.
1940–2020
Postwar growth, 1940–2020
The town went from about 1,800 people in 1940 to 5,290 in 1970, 7,377 in 2000 and 8,470 in 2020, so most of today's houses postdate 1950. In 1995 Town Meeting limited new dwelling permits to 24 a year, a cap that as written ran through 2010. On a newer house the questions are septic capacity and the Stretch code, not history.

Septic
Bedrooms are rooms divided by two
For septic design, the Board of Health sets the bedroom count at the total number of rooms divided by two, rounded down, whatever the rooms are called. Winter-usable sunrooms, three-season rooms and screened porches count as rooms. New and replacement systems are sized for a garbage grinder: at least a 1,500/500-gallon two-compartment tank and a leach area 50% larger than Title 5 requires. Finishing a basement room or closing in a porch can change the count.

Local note
Within 1,000 ft of a named brook
Land within 1,000 ft of Parker, Penn, Bulford, Lufkins, Muddy, Wheeler, Jackman, Great Sweep or Plough Brook, or their tributaries, is in the Water Resource District. There the Board of Health limits septic loading to one bedroom per 10,000 sq ft of lot, and zoning requires a special permit to make more than 40% of the lot impervious.
Coastal & wetlands
A local wetlands bylaw, with its own fee
Georgetown's bylaw, adopted in 1986 under home rule, covers work within 100 ft of wetlands, banks and land subject to flooding, and within 200 ft of any river, perennial stream, brook or creek. It carries its own filing fee on top of the state's, the Commission can bill for consultant review, and permits generally run three years. Board of Health rules also keep leach fields 100 ft from ponds, streams, wetlands and drainage ditches.

Energy code
Stretch code since July 2019
Georgetown has enforced the Stretch code since July 1, 2019. An addition over 1,000 sq ft of conditioned space, or one that more than doubles the existing conditioned area, means the whole house has to meet a HERS target, blower-door test included. Smaller additions follow the prescriptive path. Finishing an attic or basement without changing the footprint or roofline needs no HERS rating.

ADU rules
ADUs by right in the RA, RB and RC districts
Since December 2024, an ADU up to 900 sq ft or half the house's gross floor area, whichever is smaller, is allowed by right in the RA, RB and RC districts. It needs one off-street space unless it is within half a mile of transit, its own house number visible from outside, and a design that keeps the main house's character. No short-term rentals, no separate sale. On many lots the septic rules set the size before zoning does. The state side is in our ADU guide.

What we build here
What we build in Georgetown
Home additions
On a Georgetown septic lot, an addition's room count matters as much as its square footage, since every two rooms count as a bedroom for design. Past 1,000 sq ft of new conditioned space, the Stretch code adds a whole-house HERS rating.
ADUs and in-law suites
The by-right ADU rules are straightforward. The Board of Health's room-count math, and near the brooks the one-bedroom-per-10,000-sq-ft limit, are what often set the size. A detached unit also has to meet fire code separation.
Basements & lower levels
Finishing a basement can add rooms to the septic count even with no bedroom in it, so we check the system's design count before framing a playroom or office downstairs. Under the Stretch code, bringing basement space into conditioned area without changing the footprint needs no HERS rating.
Historic renovation
For the First Period houses and the older village houses, partial demolition goes to the Historical Commission when the building is 75 or older and on its inventory. We plan the ell or rear-wall removal around that review instead of discovering it at permit time.
Questions
Questions we hear in Georgetown
Can I add an ADU to my Georgetown home?
Yes. In the RA, RB and RC districts an ADU up to 900 sq ft or half the main house's floor area, whichever is smaller, is allowed by right. It must meet the dimensional schedule, have one off-street space unless it is near transit, carry its own visible house number and keep the house's character. It cannot be a short-term rental or be sold separately. Septic capacity under the Board of Health's rules is often the deciding factor. The Building Inspector can confirm current requirements.
How many bedrooms will my septic system allow?
For design, Georgetown's Board of Health counts bedrooms as the total number of rooms divided by two, rounded down, whatever you call them. Sunrooms and porches usable in winter count. New and replacement systems are sized for a garbage grinder, though the Board can waive that for repairs of failed systems on a showing of hardship. In the Groundwater Protection or Water Resource districts, loading is limited to one bedroom per 10,000 sq ft of lot.
Will removing part of an old house for an addition trigger historic review?
Possibly. Buildings at least 75 years old that are on the Historical Commission's inventory, or that it votes significant, fall under the demolition-delay bylaw in whole or in part. If the Commission finds the building preferably preserved, the demolition permit can be held for six months. For a partial demolition it can let the work go ahead if the building's significance will not be materially diminished.
Does Georgetown use the Stretch energy code?
Yes, since July 1, 2019. Large additions, over 1,000 sq ft of conditioned space or more than double the existing conditioned area, need a whole-house HERS rating. Smaller additions follow prescriptive insulation, window and mechanical requirements. A later Town Meeting vote could change the tier, so confirm with the Building Inspector.
Who handles power and water for an addition or a detached ADU?
The town does. The Georgetown Municipal Light Department handles electric service, including upgrades for heat pumps, EV charging or a detached ADU, and the Georgetown Water Department handles water service. We contact both early in design.
