Building Codes

All of our house plans are designed to meet or exceed the International Residential Code which has become the recognized standard. The IRC has supplanted all the former Building Codes including the BOCA, SBCCI, and CABO codes. Only the UBC Building Code still exists in several locations but all plans also meet the general criteria of UBC.

Some states, counties, and municipalities have their own codes, zoning requirements, and building regulations. However, the 20 states that have adopted the IRC have typically made very few changes. Modifications may be necessary to meet local building codes most notably for earthquake, hurricane (wind) design, floodplain issues, or heavy snow loading. Some states and certain cities may require an architect’s or engineer’s seal. Where required, these are readily obtained locally for a fee. Nevada is an exception where plans must be provided by a Nevada Registered Professional.

After you receive your plans, you should consult your local builder, architect, engineer, or other construction professional to review your plans before actual construction begins. We cannot be responsible for the advice or assistance you receive from them or for the methods that they use. The owner and contractor assume the responsibility to meet all local codes. The International Conference of Building Officials (ICBO) has been the leading source of building and related construction codes for more than 75 years. Our association prides itself on providing excellent products and services to ensure the public’s safety.
