Homes in Caldwell
Caldwell is a city of houses: of its 22,378 homes, 79% are detached, 3% are townhouses and other attached houses and 12% are apartments or units in buildings of two or more homes.
Much of Caldwell is new: 56% of homes were built 2000 or later, and only 29% before 1980. The median home dates from 2003. Owners live in 73% of homes.
Of the 8 Idaho cities we have census figures for, Caldwell has some of the newest homes and the smallest share of apartments. Its housing is much like Nampa's, 6 miles away. Nationally, Caldwell's homes are newer than those in 75% of the 881 US cities we have census figures for.

Shallow openings
56% of homes were built in 2000 or later. Newer windows are often set close to the room side of the wall, and handles, cranks and alarm sensors stick out into the space a louver swings through. Measure the depth to the glass and to anything that sticks out; the designer checks it against the louver size you pick.
Whole-house orders
With 79% of homes detached, most orders here cover a whole house: bedrooms, a patio door, perhaps a bay. Put every window in one list in the designer so the louver size and colour match from the street, and if you have an HOA, send it the drawings before you order.
Rounded drywall corners
71% of homes here were built from 1980 on, and many houses of that era have rounded ("bullnose") drywall corners around the windows instead of square returns. A shutter can't sit flat against a curve: choose an outside mount with a frame that clears the corner, or an inside mount if the flat part of the opening is deep enough for your louvers.
Manufactured homes
5% of homes are mobile or manufactured homes, whose windows usually sit in thin walls with little depth inside the opening. An outside mount on a frame is the reliable choice there, fixed into the framing around the window rather than the thin wall panel.

Cold winters
With 132 freezing nights a year, warm room air meets cold glass for months. Shutters closed tight overnight hold that air against the window, so condensation can collect on the sill: tilt the louvers open in the morning, and wipe the sill on windows that often run wet.
Dry air
Only 12.1 inches of precipitation a year, and days and nights about 27°F apart. Dry air pulls moisture out of wood, so poplar louvers can shrink very slightly through their first dry season; that's normal for real wood.
