If a person who is a member of the Church of Jesus Christ of Latter-day Saints (commonly called the "Mormon" church) puts a star on their home, it is probably just used as a simple decoration or symbol of patriotism. This would be the case unless it is an active-duty military star on a door or window, which means a family member is currently serving in the military.
On historic Mormon buildings, stars were often used as a symbol of Christianity. Historically, stars have been used in Christianity to represent many things, including the five wounds of Christ and the five joys of Mary (Annunciation, Nativity, Resurrection, Ascention, and Assumption). In Mormonism, the star may also have different symbolism. If there are both large and small upright five-pointed stars they will represent the governing and saving power of the priesthood. Upright stars with no size variation, espeically when combined with suns and moons, represent the Terrestrial Kingdom of God, and inverted five-pointed stars represent the 'morning stars' - the sons of God. (Revelation 22:16) If there are both inverted and upright stars, they may represent the our prayers ascending to heaven (upright stars), and the anwers to the descending (inverted stars). A six pointed star may represent the Twelve Tribes of Israel or the actual stars as a symbol of creation.
