Height restriction laws are laws that restrict the maximum height of structures.

There are a variety of reasons for these measures. Some restrictions limit the height of new buildings so as not to block views of an older work decreed to be an important landmark by a government. For example, in the Russian capital of Saint Petersburg, buildings could not be taller than the Winter Palace.

Other restrictions are because of practical concern, such as around airports to prevent any danger to flight safety.

Height restriction laws sometimes become a point of contention in cities due to their use in regulating the growth of the housing supply. Fast growth of housing supply benefits renters by producing low prices and more choice, while slow or no growth in housing supply benefits property owners by allowing them to charge higher prices. In this way, height restriction laws often become part of a class conflict even when their original purpose was innocuous.
