Most Church meetinghouses owned by the Church of Jesus Christ of Latter-day Saints (the "Mormon" or "LDS" church) have a spire or steeple. Not only do spires or steeples help others recognize the building as a religious building, they also hold symbolism. Steeples and spires point to heaven and represent that the Church is pointing people to heaven, or directing their attention to heaven.
On LDS Temples, sometimes there is more than one spire, and sometimes there are none at all. Most temples have a gold statue of the angel Moroni on one of the spires, who is announcing the restoration of the Gospel of Jesus Christ through his Trumpet.
Photos of various LDS church and temple spires can be seen at the "Related Links" below.
There is no specified height, it all depends on the design and size of the building and the zoning requirements in the city where it is built. Some LDS churches don't have any spires because they are prohibited by local laws. Check out the "Related Links" below to see examples of various LDS church meetinghouses and their different spires.
I don't know why you asked that question. "LDS" means "Latter Day Saints" and refers to anyone who is a member of the church of Jesus Christ of Latter Day Saints, or LDS church. That is pretty self explanatory. So the LDS were ALWAYS allowed in the LDS church because the LDS church is made up of only LDS people. Duh.
Many Christian churchs of different demoninations have a spire or a steeple on the top of their church.

LDS stands for "Latter-day Saint". Someone who says that they are "LDS" is a member of the Church of Jesus Christ of Latter-day Saints (the "Mormon" church). Members of the Church prefer to use the abbreviation LDS rather than the nickname "Mormon".
My research would indicate that the church spire is 200ft high - see link below.
