Apartment buildings are [[multi-story]] buildings where three or more residences are contained within one structure. Such a building may be called an ''apartment building'', ''apartment complex'', ''flat complex'', ''block of flats'', ''tower block'', ''high-rise'' or, occasionally, ''mansion block'' (in British English), especially if it consists of many apartments for rent. A high-rise apartment building is commonly referred to as a ''residential tower'', ''apartment tower'', or ''block of flats'' in Australia.

A [[high-rise building]] is defined by its height differently in various [[jurisdiction]]s. It may be only residential, in which case it might also be called a tower block, or it might include other functions such as hotels, offices, or shops. There is no clear difference between a tower block and a [[skyscraper]], although a building with fifty or more stories is generally considered a skyscraper.<ref>{{cite web|url=https://www.britannica.com/EBchecked/topic/547956/skyscraper|title=skyscraper|publisher=Encyclopædia Britannica, Inc|access-date=19 September 2012}}</ref> High-rise buildings became possible with the invention of the [[elevator]] (lift) and cheaper, more abundant building materials. Their [[structural system]] usually is made of [[reinforced concrete]] and [[steel]].

A [[low-rise building]] and mid-rise buildings have fewer stories, but the limits are not always clear. [[Emporis]] defines a low-rise as "an enclosed structure below 35 metres [115 feet] which is divided into regular floor levels."<ref>{{cite web |url=http://standards.emporis.com/?nav=realestate&lng=3&esn=49213 |archive-url=https://web.archive.org/web/20110710191558/http://standards.emporis.com/?nav=realestate&lng=3&esn=49213 |url-status=usurped |archive-date=10 July 2011 |title=Data Standards: Structures - low-rise building |publisher=Emporis Standards |access-date=10 June 2009}}</ref> The city of [[Toronto]] defines a mid-rise as a building between 4 and 12 stories.<ref>{{cite web|url=http://faculty.geog.utoronto.ca/Hess/Courses/studio/presentation%20on%20avenues%20and%20mid-rise%20study.pdf |title=Microsoft PowerPoint - 3-Lorna [Compatibility Mode&#93; |date= |accessdate=2022-03-08 |archive-url=https://web.archive.org/web/20110816002149/http://faculty.geog.utoronto.ca/Hess/Courses/studio/presentation%20on%20avenues%20and%20mid-rise%20study.pdf |archive-date=2011-08-16 |url-status=live }}</ref>
