Flag Position on the House
In 2009, when we repainted the house, we researched if it mattered what side of the door the flag should be on the house. We were surprised to find out that it does matter.
In 1942, the federal government established the federal Flag Code detailing how to properly display and use the U.S. flag.
According to §175. Position and manner of display, section (i):
When displayed either horizontally or vertically against a wall, the union should be uppermost and to the flag's own right, that is, to the observer's left. When displayed in a window, the flag should be displayed in the same way, with the union or blue field to the left of the observer in the street.
This means that the flag should be positioned to the left side of the front door, not the right.
