Professional code development organizations typically publish new code additions every three years.

• A. Every year
• B. Every two years
• C. Every three years
• D. Every five years

Answer: (C)

Code development cycles are multi-year because model codes undergo extensive review, public input, committee actions, and coordination with referenced standards before a new edition is released. Major code bodies publish a new edition on a three-year cycle, which provides enough time for drafting, hearings, and jurisdictional adoption while keeping the codes reasonably current with safety practices and technology. Between editions, updates may appear as addenda or corrections, but the formal edition comes on the three-year schedule. Updating every year would rush the process and raise costs; a two-year cycle would be too frequent for thorough evaluation, and a five-year cycle would delay needed changes. Three years is the common balance that maintains rigor and practicality.
