Maine sets one energy code for the whole state, so every town in Sagadahoc County holds a replacement window to the same figure: a U-factor of 0.30 or lower under the 2021 International Energy Conservation Code, with no limit on solar heat gain. A town of more than 4,000 people has to enforce that code; a smaller one may leave it unenforced, but the state still counts meeting it as the owner's job. Permits still change from place to place: Arrowsic publishes no re-side rule, while Bath makes a re-side permit depend on the job.
54.1% of the housing in Sagadahoc County was built before 1980, and 27.1% before 1940 (5,216 of 19,239 units): the share that decides how often the federal lead rule is on a window or siding job here.

Things worth knowing before you sign anything
- Arrowsic: All land within 250 feet of the rivers, salt water or Sewall Pond is in Arrowsic's shoreland district, where smaller additions and replacements over 200 square feet need a conditional use permit as well.
- Bath: Inside Bath's Historic Overlay District, altering or covering exterior architectural details needs Historic District Review before a building permit, and the city's code asks for original materials to be kept or repaired where possible and replaced with the same material, or a substitute of the same color, shape, size and texture, so a re-side or new windows on a building there should start with a call to the city about that review.
- Bowdoinham: A building permit is required to construct, alter, relocate, demolish or replace a building or part of one, so anything beyond like-for-like repair is a conversation with the town first.
- Georgetown: In the shoreland zone, the Shoreland Zoning Ordinance also allows normal maintenance and repair, naming replacing siding and replacing windows, without a permit. Contractors must arrange private disposal of construction debris, because the Georgetown Transfer Station does not take it.
- Phippsburg: Permits must be posted on site.
- Richmond: In the National Register historic area of Richmond's Village District along the Kennebec, no historic building may be changed on the outside until the Code Officer approves, after review by a registered architect and the Planning Board.
- Topsham: In the town's Historic District, work visible from the street needs a Certificate of Appropriateness from the Historic District Commission; paint color is not reviewed.
