In Massachusetts, full-frame window replacement and any change to the size of an opening need a building permit, everywhere. Same-size insert replacement needs one in most towns too, because the state code treats a complete window replacement as work that must meet the energy, egress and safety-glazing rules, and the only true exemption is an ordinary repair such as a new pane of glass or a sash cord. The permit is pulled by the installer under a Construction Supervisor License, the fee runs $15 to $21 per $1,000 of job cost in the towns we work in, and a window permit is usually issued in days, with the state allowing up to 30. If the house is in a historic district, the commission's certificate comes first. We file every permit we need and it is in the quote.
what the state code says
Ordinary repairs versus replacement
The current (10th) edition of 780 CMR says no application is required for ordinary repairs. Reglazing a broken pane, replacing a sash cord or a lock, and repairing a sash are ordinary repairs. Replacing the window unit is not: the existing-buildings chapter requires that the complete replacement of windows comply with the code, which is why a town can require a permit for a same-size insert. Enlarging an opening always needs a permit because it needs a new header and framing.
Energy code
Replacement windows in a house must meet a U-factor of 0.30 or better under both the base code and the stretch code that most towns around Boston have adopted; there is no solar heat gain limit in our climate zone. Every window we install meets it. Designated historic buildings can be exempted where meeting the number would alter the building's character.
Egress and safety glass
A bedroom needs an emergency escape window with a clear opening of 5.7 square feet, at least 24 inches high and 20 inches wide, with the sill no more than 44 inches off the floor. A replacement in an existing bedroom opening is allowed without meeting those numbers as long as it does not significantly reduce the existing opening; enlarge or reframe the opening and the new window must comply. Tempered or laminated safety glass is required within 24 inches of a door, near tubs and showers, next to stairs, and in large low panes.
Lead paint
On a house built before 1978, window replacement disturbs painted trim and must be done by a Lead-Safe Renovation Contractor licensed by the state under 454 CMR 22, with containment, cleanup and verification, and you should receive the Renovate Right pamphlet and a confirmation form before the work starts. It is not part of the building permit, but a building inspector will ask.
who pulls the permit
The contractor, under a Construction Supervisor License, with a Home Improvement Contractor registration for work on a one to four family house. An owner-occupant of a one or two family home can pull the permit under a homeowner affidavit, but that makes the owner the contractor of record and waives the protection of the state's Guaranty Fund, which towns from Winchester to Brookline spell out on their permit pages. If a window company asks you to pull the permit yourself, ask why.

On a typical ten-window job at our prices, $12,000 to $18,000 installed, the permit comes to roughly $180 to $380 depending on the town. The state gives the building official 30 days to act on an application; window permits with a complete application are usually issued in a few days to two weeks. A historic district certificate, where one is needed, adds the commission's monthly cycle in front of that. Our installed prices are below; the permit is included in every quote.
Double insulated low-E glass, installation and project management are included.

what happens if you skip the permit
Towns find unpermitted window work at the next sale, when the buyer's inspector or the lender asks for the permit history, and at the next permit for anything else, when an inspector sees new windows with no record. The cure is a retroactive permit at a doubled or tripled fee, an inspection of work that is already closed up, and sometimes the removal of trim so the flashing can be seen. On an insurance claim after a leak, an unpermitted installation is the first thing an adjuster looks for. The fee is a small fraction of one window; the record stays with the house.

frequently asked questions
Do I need a permit to replace windows in Massachusetts?
Yes for full-frame replacement and any size change, everywhere in the state. For same-size inserts, most towns around Boston require one because the work falls under the energy code; we check your town and file it either way when it is required.
How much is a window permit?
Most towns charge $15 to $21 per $1,000 of job cost with a $50 minimum, so roughly $180 to $380 on a ten-window job. Needham uses a flat fee for the first $15,000. It is included in our quote.
Can I pull the permit myself?
An owner-occupant of a one or two family house can, under a homeowner affidavit, but you become the contractor of record and give up the state Guaranty Fund protection. We pull it under our license instead.
How long does a window permit take?
Usually days to two weeks with a complete application; the state allows up to 30. A historic district adds a month or two in front of the permit.
Do replacement windows have to meet egress?
A replacement in an existing bedroom opening is allowed as long as it does not significantly reduce the opening. If the opening is changed, the new window must meet the full egress size.
