    Building height limitation

    Dear colleagues
    Zoning regulation system is being implemented in Russia now. I’m studying zoning and could not find an exact answer for “what is an ultimate of height limitation?”. Density limitation is sensitive, but it is possible to achieve permitted density by different heights of buildings. So, height is city shaping (some aesthetic issue) or what?
    Thank you.

    Height limitations can often be based on practical considerations, such as wanting to limit heights to protect important views, or limiting heights to correspond to the capabilities of the city's fire fighting equipment.

    We have height limitations of 30 feet largely to protect solar access. That is, we want to avoid a new building creating a shadow so that its neighbor has no sun. In the mountains, sun is particularly important because it helps to melt heavy snow off the roof and prevent roof damage.

    Like Cardinal and progmac mentioned, those are some to consider.

    Yes, that's one. Another factor to consider is restriction along aviation paths especially buildings within the airports and airfields. Another thing is structural consideration especially when bearing capacity of soil is weak. Otherwise, towers will cost more and resiliency of building will be affected.

    Also, the USA has a nationwide height limit of just over 600 meters above ground without special permission from the FAA (the Federal Aviation Administration, USA's civil aviation regulators). Right now, there is a building under construction in downtown Chicago that will go right up to that limit.

    Aside from that, it seems to me that most zoning regulations are based more on the vanity and aesthetic eyes of those setting the rules than on any practical, physically-based limitations.

    Yes, you can limit the number of people living in an area by limiting the number of available units and height limits are one way of doing that, but you also run the risk of creating a housing shortage and fostering 'illegal' unit sharing (this is happening in some parts of the USA).
