The US Department of Housing and Urban Development provides information on residential construction codes adopted under the Fair Housing Accessibility Guidelines.

This information can be accessed at http://www.hud.gov/offices/fheo/disabilities/fhguidelines/fhefha5.cfm.

Some people need specific types of structural modifications to make a home fully accessible while others have different needs. In most parts of the country, new homes are being designed to meet the specifications of universal design.

These specifications can be found on the web site of The Center for Universal Design at http://www.design.ncsu.edu/cud/about_ud/udprinciples.htm.

You can also find a number of very helpful articles and resources at http://www.makoa.org/accessable-design.htm.
