Basis of Presentation [Abstract]
Basis of Presentation	Century Communities, Inc. (which we refer to as “we,” “CCS,” or the “Company”), together with its subsidiaries, is engaged in the development, design, construction, marketing and sale of single-family attached and detached homes in metropolitan areas in 17 states. In many of our projects, in addition to building homes, we are responsible for the entitlement and development of the underlying land. We build and sell homes under our Century Communities and Century Complete brands. Our Century Communities brand targets a wide range of buyer profiles including: first time, first and second time move up, and lifestyle homebuyers, and provides our homebuyers with the ability to personalize their homes through certain option and upgrade selections. Our Century Complete brand targets first time homebuyers, primarily sells homes through retail studios and the internet, and provides no option or upgrade selections. Our homebuilding operations are organized into the following five reportable segments: West, Mountain, Texas, Southeast, and Century Complete. Additionally, our indirect wholly owned subsidiaries, Inspire Home Loans, Inc., Parkway Title, LLC, and IHL Home Insurance Agency, LLC, which provide mortgage, title, and insurance services, respectively, to our homebuyers, have been identified as our Financial Services segment.

Interim results of operations are not necessarily indicative of the results that may be achieved for the full year, particularly in light of the novel coronavirus (COVID-19) pandemic and measures intended to mitigate the spread.

The COVID-19 pandemic has led to adverse impacts on the U.S. and global economies and initially created uncertainty regarding potential impacts to our operations and customer demand. Commencing in March 2020, numerous state and local municipalities issued public health orders with varying expiration dates requiring the closure of nonessential businesses, as well as ordering individuals to stay at home and/or shelter in place whenever possible. These public health orders generally exempted the sale and construction of new homes, other than a small portion of our operations, which had to cease operations in early April. During the latter half of the second quarter of 2020, state and local municipalities in the majority of our markets began to lift the most stringent of the public health restrictions and numerous nonessential businesses were allowed to reopen. As of the date of this filing and throughout the third quarter of 2020, we are and were able to build and sell homes in all of our markets.
