Two of the nation's largest cities have adopted building safety and fire prevention codes developed by the International Code Council to guide construction and protect the residents of their communities.

Dallas adopted the 2000 International Building, Mechanical, Plumbing, Fire, Energy Conservation, Residential and Existing Building Codes.

Denver updated its building safety and fire prevention codes for the first time since 1997, when it adopted several I-Codes. Effective Oct. 1, the Colorado capital will enforce the 2003 International Building, Residential, Fire, Mechanical, Plumbing, Fuel Gas and Energy Conservation Codes.
