Homes in Union City
Union City's 21,901 homes are a mix: 58% detached houses, 24% apartments or units in buildings of two or more homes and 12% townhouses and other attached houses.
The biggest building period was 1950 to 1979, which accounts for 48% of homes standing today; 17% are from 2000 or later. The median home dates from 1980. 65% of homes are lived in by their owners.
In nearby Hayward, 5 miles away, 62% of homes were built before 1980, so Union City's windows are on the whole newer. Nationally, Union City's homes are older than those in 54% of the 881 US cities we have census figures for.

Replacement windows
48% 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.
Out-of-square openings
With 52% 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.
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.

Dry summers, wet winters
Barely any of the year's precipitation falls in June, July and August; most comes in the cool months. Wood takes on moisture in the wet season and gives it back in the dry one, so expect the panels to feel slightly tighter in winter than in summer. Fit them in the season you're in, and leave the hinge screws a quarter turn from tight until they've been through both.
