This website is an anthology of the codes, laws and related documents that have created, or sought to create, particular urban forms. It is a searchable archive drawn from a broad array of historical documents. We have selected documents from around the world, and from all time periods.

We include both legally-binding codes as well as customary rules that may not have involved a governing authority. These documents provide a rich cultural resource for urban planners, architects, and all others involved in the construction of place.

The Codes Project is funded by
the National Endowment for the Arts

Additional funding provided by:
Duany Plater-Zyberk & Co.
