Which statement best describes the cadence of code additions by professional code development organizations?

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

Answer: (C)

Codes are typically updated on a three-year cycle. This pace balances the need for meaningful, consensus-driven changes with the reality that jurisdictions must adopt, adopt training, and update inspections and products. The process involves broad stakeholder input, public review, testing, and coordination across different code areas, all of which take time. If updates happened every year or every two years, resources would be strained and changes could be harder to implement consistently; waiting five years would slow needed improvements. Because of these practicalities, three years is the standard cadence for major code updates.
