Additions to buildings MUST comply with

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

Answer: (A)

Additions to buildings are treated as new construction, so they must comply with the current edition of the code that governs new construction. This ensures the added portion meets today’s standards for safety, structural integrity, fire protection, egress, and energy efficiency, regardless of when the existing structure was built. The energy code and fire code are part of that current code framework, but the placement here is that the addition must conform to the current code for new construction rather than the older code that applied to the original building.
