Homes in Sioux City
Sioux City is a city of houses: of its 35,001 homes, 70% are detached, 4% are townhouses and other attached houses and 23% are apartments or units in buildings of two or more homes.
More homes here were built before 1950 than in any later period we count: 41%. Only 9% date from 2000 or later. The median home dates from 1957. 65% of homes are lived in by their owners.
Of the 11 Iowa cities we have census figures for, Sioux City has the highest share of older homes and the smallest share of apartments. In nearby Sioux Falls, 75 miles away, 35% of homes were built before 1980, so Sioux City's windows are on the whole older. Nationally, Sioux City's homes are older than those in 88% of the 881 US cities we have census figures for.

Plaster walls and deep casings
41% of homes date from before 1950, when walls were plaster on lath and windows sat in deep wood casings. Plaster cracks if you drive screws carelessly: drill a pilot hole, use fixings made for plaster, and fix into the casing or the framing behind it. A deep casing is good news for an inside mount; measure its depth before you choose a louver size.
Out-of-square openings
With 78% of homes built before 1980, many openings have had decades to settle. Measure each one's width at the top, middle and bottom, and both diagonals. If the diagonals differ by more than about ¼ inch, add a mounting frame in the designer, or choose an outside mount so the shutter covers the uneven edges.
Whole-house orders
With 70% 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.
Replacement windows
37% of homes went up between 1950 and 1979, and most of them have had their original windows replaced since. A replacement window often sits further into or out of the wall than the old one, so the depth you have for an inside mount may differ from window to window in the same house. Measure every opening rather than copying one.

Cold winters
With 160 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.
