Homes in Chicago
Apartments outnumber houses in Chicago: 71% of its 1,277,054 homes are in buildings of two or more units. Detached houses make up 26% and townhouses and other attached houses 4%.
More homes here were built before 1950 than in any later period we count: 47%. Only 15% date from 2000 or later. The median home dates from 1953. 46% of homes are lived in by their owners.
Of the 30 Illinois cities we have census figures for, Chicago has the highest share of apartments. In nearby Cicero, 4 miles away, 92% of homes were built before 1980, so Chicago's windows are on the whole newer. Nationally, Chicago's homes are older than those in 83% of the 881 US cities we have census figures for.

Plaster walls and deep casings
47% 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.
Apartments and condos
71% of homes are in buildings of two or more units. Balcony and patio doors suit bypass or bifold panels rather than hinged ones, which need floor space to swing. Check what your HOA or building allows to show from outside before you order: most rules are about the colour seen through the glass.
Out-of-square openings
With 75% 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.

Cold winters
With 97 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.
