Additions to buildings MUST follow which standard?

• A. The current code for new construction
• B. The existing code
• C. The energy code
• D. The fire code

Answer: (A)

Additions to a building are treated as new construction, so they must follow the current building code in effect at the time the work is done. This ensures the added portion meets the latest safety, structural, and energy requirements, even if the existing structure doesn’t change. The current code for new construction provides the comprehensive standards that apply to the added work. Relying on the existing code would leave the new work potentially out of date, and while the energy code and fire code are important parts of the overall code package, they don’t replace the requirement to comply with the current code for new construction.
