Permits
Permits for siding, windows and decks in Billerica
A checklist by job. Billerica posts what each residential permit needs. For a deck or shed: a "Certified Plot Plan (Showing Proposed Addition Location) *No Mortgage Inspection Plans*," two sets of building plans, the contractor's construction supervisor license and HIC registration or a homeowner affidavit, a workers' compensation affidavit and a signed contract. For siding, roofing, windows or insulation: the application, CSL and HIC or homeowner affidavit, workers' compensation and signed contract, plus an "Electrical Permit pulled by a Licensed Electrician (Siding Only)." Energy compliance with a HERS rating is listed only for additions and new construction (Residential Permit Application Required Forms).
Homeowners, filing and fees. The Building Department FAQ says a plot plan is needed whenever a structure or living space is added, and homeowners may pull a building permit once a homeowners exemption form is on file (Building FAQ). Permits are filed through MapsOnline. The town posts its fee schedule as a scanned PDF; check it, or call the Building Department, for current amounts.

State rules for exterior contractors. On the state's contractor chart, which it calls general guidance, siding and window installation or replacement need a building permit and at least a "Window/Siding" construction supervisor license; decks, exterior stairs, structural carpentry and new door installations need a permit and a supervisor license; and a replacement door needs a permit "if an exit door or for public safety concerns" (HIC contractor resources). Contractors working on an owner-occupied home of one to four units must hold Home Improvement Contractor registration (registration lookup). Over $1,000, the contract must be written, with the registration number, start and completion dates, price and payment schedule; the deposit is capped at one-third unless special-order materials cost more; and a contract signed at home can be cancelled until midnight of the third business day (c.142A §2). An owner who takes out the permit is excluded from the Guaranty Fund, which can pay up to $25,000 of losses against a registered contractor (HIC homeowner resources).
Energy code. Billerica has used the Stretch Code since July 1, 2018 and has not adopted the Specialized Code (energy code adoption by municipality). Replacement windows must meet the energy code's U-factor for new windows; ask your installer for the NFRC label.
Lead paint and cement siding. The town posts no lead guidance. Under state rules, paid work on a pre-1978 home that disturbs more than 20 square feet of exterior paint needs a licensed Lead-Safe Renovation Contractor (MA lead-safe renovation), and the federal rule covers every window replacement regardless of square footage (EPA RRP). MassDEP lists cement or "transite" siding as suspect asbestos: it may not be broken, sanded, sawed or drilled, removal is notified at least ten working days ahead, and a DLS-licensed inspector's survey is required unless an owner is doing the work on their own owner-occupied single-family home (MassDEP asbestos FAQ).

Historic review
Historic review of exteriors in Billerica
Four districts. The Historic Districts Commission lists four local historic districts, Center, North Billerica Mills, Corner and Richardson's Mill, and reviews and approves "any exterior changes to existing buildings within the district." Applications are $25 for minor and $50 for major work, with no fee for an informal meeting or to verify non-applicability, and the Commission meets the first Wednesday of each month at 7 p.m. The page also links resources on restoring wood windows and on storm windows for historic buildings (Historic Districts Commission). The town's 2006 Development Guide puts it simply: "Most exterior work requires a Certificate from the Historic Districts Commission" (Development Guide).
What's reviewed and what isn't. The district bylaw reviews exterior features "open to view from a public street, public way, public park, or public body of water." It excludes storm windows, window screens and window air conditioners, and paint color on houses "(but not the color of roofing materials)," and provides certificates of appropriateness, non-applicability and hardship (historic districts bylaw).
Demolition review. As compiled in 2005, the town's Demolition Review By-Law defines demolition as pulling down, destroying, removing or razing a building or structure "or any portion thereof," and its permit requirement covers partial demolition or removal. There is no age threshold; significance follows from Register, district or inventory listing or a Commission vote. For a building found preferably preserved, the 2005 text holds the demolition permit for six months after notification (General By-Laws through May 2005). Ask the Building Department about later amendments before taking off an old porch.
Decks and porches
Decks and porches in Billerica
Setbacks. The only accessory setbacks Billerica posts are for sheds: 100 square feet or less may go in a side or rear yard, and larger sheds need "a 15' side set-back and 20' rear set back" (Building FAQ). For a deck or porch, the certified plot plan is where the Building Department checks setbacks, so get the survey before you size the deck.
No septic trigger for decks. Billerica's Board of Health Chapter 5, amended June 2, 2025, ties septic upgrades to living-space additions, but "a porch, deck, screen house, etc., shall also be exempt from the requirement to upgrade" (Board of Health Chapter 5).
Floodplain and wetlands. The same Chapter 5 bars new construction in the floodplain and within 25 feet of it unless the Board grants a variance, requires review for work between 25 and 100 feet away, and uses FEMA flood maps dated July 8, 2025 (Board of Health Chapter 5). The 2006 Development Guide adds that development below the 100-year flood elevation may need "a Flood Plain District Special Permit from the Board of Appeal" (Development Guide). The wetlands bylaw reaches 100 feet from a resource area and 200 feet from a river, and its regulations, approved June 25, 2008, require a 50-foot undisturbed strip on undeveloped lots and 25 feet on lots developed as of June 27, 2003 (Wetland Protection Regulations).
Footings and stairs. The town posts no deck guide or frost depth. Massachusetts sets frost depth at 48 inches and limits exterior stair risers to 8¼ inches with treads of at least 9 inches (780 CMR 51, chapter 3). Dig Safe needs at least 72 hours' notice before footings are augered, not counting weekends and legal holidays (c.82 §40A); call 811 (Dig Safe).
Billerica's homes
Federal houses, mill rows and lake bungalows
The state's 1980 survey of Billerica traces central-chimney colonials, high-style Federal houses with hip roofs, mill workers' row houses, and Victorian double houses, then a wave of modest bungalows and small Colonial Revival cottages between 1915 and 1940 (MHC reconnaissance report).
North Billerica
Wood-frame two-story mill workers' row houses from about 1835–45, Greek Revival double cottages, and Victorian Gothic and Queen Anne double houses.
Billerica Center
High-style Federal houses, plus Italianate, Queen Anne and Colonial Revival houses.
Pinehurst and Nutting Lake
Subdivisions laid out around 1910–20, filled with modest bungalows and small Colonial Revival cottages.
On any of these older houses, lead-safe rules apply to window and siding work, and near the Center and the North Billerica mills, check whether the house sits in one of the historic districts before choosing siding or windows.
FAQ
Billerica exterior questions
Why does a siding job in Billerica need an electrical permit?
The town's list of required forms for siding, roofing, windows and insulation includes an electrical permit pulled by a licensed electrician for siding jobs only, along with the contractor's CSL and HIC registration (or a homeowner affidavit), workers' compensation affidavit and signed contract.
What does Billerica need for a deck permit?
A certified plot plan showing where the deck goes (mortgage inspection plans are not accepted), two sets of building plans, the contractor's CSL and HIC registration or a homeowner affidavit, a workers' compensation affidavit and a signed contract.
Can I put storm windows on a house in a Billerica historic district?
Yes. The historic districts bylaw excludes storm windows, window screens and window air conditioners from review, along with paint color on houses (but not roof color). Most other exterior changes visible from a street, park or body of water need a certificate from the Historic Districts Commission.
Can I build a deck near the floodplain in Billerica?
The Board of Health's Chapter 5, as amended June 2, 2025, bars new construction in the floodplain and within 25 feet of it unless the Board grants a variance, and requires review for work between 25 and 100 feet away, using FEMA maps dated July 8, 2025. Ask the Board of Health and Building Department before you plan.
What does it cost me to use New England Exterior Pros?
Nothing. Asking is free for homeowners; the contractor prices the job, and the price and contract are between you and them.
