Homes in Rockville
Rockville's 28,289 homes are a mix: 41% detached houses, 45% apartments or units in buildings of two or more homes and 14% townhouses and other attached houses.
The biggest building period was 1950 to 1979, which accounts for 47% of homes standing today; 34% are from 2000 or later. The median home dates from 1979. 53% of homes are lived in by their owners.
Of the 18 Maryland cities we have census figures for, Rockville has the third-highest share of apartments. In nearby Aspen Hill, 4 miles away, 70% of homes were built before 1980, so Rockville's windows are on the whole newer. Nationally, Rockville's homes are older than those in 54% of the 881 US cities we have census figures for.

Replacement windows
47% 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.
Apartments and condos
45% 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 51% 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.
Shallow openings
34% 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.

Cold winters
With 86 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.
