Hollis is a rural bedroom community of Portland along the Saco River, where water-powered mills once ran at Hollis village, Bar Mills, Moderation Falls, North Hollis and Bonny Eagle Falls. It was incorporated in 1798 as Phillipsburg and later renamed Hollis.
The houses in Hollis
In Hollis, 58% of homes went up before 1980 and 20% before 1940; the median one dates from 1977. 83% are detached single-family houses, and owners live in 88% 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.
65% of the homes in Hollis have three or more bedrooms. The median owned home is worth about $338,900 by its owner's estimate, the figure to weigh any siding or window quote against.
Half the homes in Hollis were built before 1977, which makes its housing about 3 years older than across York County as a whole (median 1980). Set against York County as a whole, owners live in 88% of occupied homes here against 77% county-wide, the median owner-estimated value is $338,900 here and $395,700 across the county and detached houses are 83% of the homes, above the county's 70%.

What that vintage turns up
The largest group of homes in Hollis, 34% 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 21% built in the 1980s and 1990s
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.

Historic districts
Hollis has 1 listed: Salmon Falls (West) 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
Hollis shares a boundary with Limington, Standish, Buxton, Dayton, Lyman, Waterboro and Saco River.

The rules in Hollis
Siding replacement No permit
No, unless the work goes below the siding. The Hollis Building Code (section 7.A.1, amended November 7, 2017) says normal maintenance, including re-roofing and residing, needs no application or permit unless underlying material such as plywood, sheetrock or framing has to be replaced, added or removed.
Window replacement, same opening Not published Enlarging or cutting an opening Permit required
Windows are not named. Replacing framing for a new or larger opening is the kind of underlying work that needs a permit.
Maine sets this, not Hollis: U-0.30 or lower
With 4,745 residents in the 2020 Census, Hollis 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.
Local quirks
Building permits are void unless work starts within 6 months, and the permit must be posted in plain view on the property within 48 hours.
