A more thorough explanation:

Building restrictions are rules that control what kind of buildings can be constructed on certain properties. These rules are usually listed in zoning ordinances or restrictive covenants in deeds. They are different from building codes, which regulate the safety and quality of construction.

For example, a zoning ordinance might restrict the height of buildings in a residential area to two stories, while a restrictive covenant might prohibit the construction of any buildings on a property except for a single-family home.

These restrictions are put in place to ensure that the buildings in a particular area are consistent with the community's values and needs. They can help maintain property values, preserve natural resources, and promote public safety.
