Acton, set off from Shapleigh in 1830, sits on the New Hampshire line and holds lake shores on Great East Lake, Wilson Lake and several ponds, with villages at Acton, South Acton and Miller Corner. Hussey Hill, at 1,051 feet, is the southernmost 1,000-foot hill in Maine, and the Acton Fair runs every late summer.
The houses in Acton
Of the homes in Acton, 56% predate 1980 and 16% predate 1940; the median one dates from 1974. Detached single-family houses make up 97%; owners live in 96% of the occupied ones. With most of the housing older than 1980, the federal lead rule is likely on most window and siding jobs here. What the lead rule requires of a contractor.
Owners here put the median home's value at about $334,300, and 40% of homes have three bedrooms or more — each bedroom needs an emergency escape opening under the egress rule.
Half the homes in Acton were built before 1974, which makes its housing about 6 years older than across York County as a whole (median 1980). Set against York County as a whole, owners live in 96% of occupied homes here against 77% county-wide, the median owner-estimated value is $334,300 here and $395,700 across the county and detached houses are 97% of the homes, above the county's 70%.

What that vintage turns up
The largest group of homes in Acton, 25% of them, was built in the 1960s and 1970s, so that is the house described here.
Aluminum sliders and single-hungs, single-glazed or with an early sealed unit, alongside the first vinyl-clad wood windows. An aluminum frame is a cold bridge: in January it collects frost and runs condensation onto the sill and the drywall return. Few of these windows are worth repairing, and on this vintage a full replacement is usually money well spent.
Raised ranches and split-levels in the new subdivisions, and lake cottages turned into year-round houses, clad in plywood panel siding, aluminum lap or the first vinyl. Plywood panels drink water at the bottom edge and at every butt joint; aluminum dents and chalks but rarely leaks. A converted camp may have siding nailed straight to the studs, with no sheathing and little or no insulation behind it.
The one to watch on a house of this age
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.
And on the 23% built in 2000 or later
Houses built to recent Maine codes are tight, and Maine now holds new houses to a lower air-leakage limit than the national code. A tight house with too little ventilation fogs its windows all winter; before blaming the glass, check the humidity and the bath and kitchen fans.

Historic districts
Acton has 1 listed: Great Falls Manufacturing Company Newichawannock Canal Historic District. A National Register listing on its own does not limit what you fit; a local district or landmark designation can, and in several towns here a change of siding material or window sash needs a certificate before the permit. Which towns' rules bind, and how.
Next door
Acton shares a boundary with Newfield, Shapleigh, Sanford, Lebanon, Milton, New Hampshire and Wakefield, New Hampshire.

The rules in Acton
Siding replacement Not published
Acton's zoning ordinance says a building or use permit must be applied for and cleared before any construction starts, and that renovations must be built to the residential code as Maine adopted it. Siding is not named.
Window replacement, same opening Not published Enlarging or cutting an opening Not published
Not published. Call the building department before ordering.
Maine sets this, not Acton: U-0.30 or lower
Acton, with 2,671 residents in the 2020 Census, is not required to enforce the state's code, but its own pages tie its permits to it.
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
The town fee schedule charges $6 per $1,000 of estimated cost for new homes and renovations.
