What that vintage turns up
The largest group of homes in North Yarmouth, 33% of them, was built in the 1980s and 1990s, so that is the house described here.
Double-glazed vinyl or clad wood windows with a nailing fin, many now thirty or forty years old. The common failure is the seal between the panes: once it lets go the glass fogs between the layers and the gas fill is gone. When the frames are still square and dry, new sealed glass in the old frame is the cheaper repair; when the frames are cracked or the sills are soft, it is time for the whole unit.
The capes, colonials and raised ranches of the subdivisions that spread across the commuter towns, sided in vinyl or cedar clapboard over plywood or particle-board sheathing, with felt paper or an early house wrap behind it. The siding itself usually holds up; what to look at is what water has done at the corners, around the windows and under any deck ledger fastened through the siding.
The one to watch on a house of this age
Windows of this era were often sealed to the wrap with caulk and little else. When the siding comes off, check the sheathing below each window's lower corners: that is where a failed caulk joint shows up first, as dark, soft wood.
And on the 24% built in the 1960s and 1970s
The bottom of the wall. Panel siding that runs down close to the ground soaks up water and snowmelt, and the rim joist and sill plate behind it rot unseen. On a converted camp, check whether there is any sheathing at all before anyone prices new siding as a simple swap.

The rules in North Yarmouth
Siding replacement No permit
No, unless something structural changes. The town's code enforcement FAQ says plainly: "If there are no structural changes, you do not need a building permit."
Window replacement, same opening No permit Enlarging or cutting an opening Permit required
The same answer covers a window in the same opening. A new or enlarged opening changes the framing, so it is a structural change and needs a permit.
Maine sets this, not North Yarmouth: U-0.30 or lower
With 4,072 residents in the 2020 Census, North Yarmouth is over the 4,000 mark at which Maine requires a town to enforce the state's building and energy code.
That is the 2021 energy code’s window figure, with no solar heat gain limit.
ENERGY STAR’s own figure here is U-0.22 or lower with an SHGC of 0.17 or higher, stricter than any code edition in force. When the code applies to a replacement window, and when it does not.
What the permit costs
Every permit carries a $25 administrative fee, and a late permit costs double.
