Every community has it's own sense of place, and they take different approaches when it comes to limiting house size. Below is a non-comprehensive list of communities that have limited house size in their own particular ways. Know of any others? Please contact us with details and we can add them to our list.

Aspen, CO

Boulder, CO

January 2, 2010: Boulder, Colorado set size limits using "compatible development rules". Boulder created an online calculator that allows people to find out what is allowed on their site.

This newspaper article discusses the rules.

Pitkin County, CO

2006: Pitkin County, Colorado set a maximum size limit of 5,750 square feet. However they have a "maximum absolute cap" of 15,000 square feet of floor space that can be attained by using transferable development rights (TDR). TDR's are designed to leave certain land undeveloped but compensates owners by transferring development rights to land designated for development. In other words, urban areas pay surrounding rural areas to remain undeveloped, in order to grow within their urban boundaries. Within Pitkin County, cities and incorporated areas have their own zoning rules so for example Aspen's house size limit is different. They further explain the logic behind TDR's on their website.

Pitkin County outlines their rules in a document "Rural living in Pitkin County"

This real estate website also offers a "2006 land use primer" on Pitkin County's rules, some of which are highlighted above.
