Identification of the underlying reasons for codes should include

• safety
• consumer protection
• legal requirements (e.g., Americans with Disabilities Act [ADA] provisions)
• standardization of fixtures (e.g., electrical; plumbing; heating, ventilation, and air conditioning [HVAC]; cabinetry)
• fire prevention
• environmental concerns and sustainability.

Identification may include discussing case studies that prompted changes in building codes.

Process/Skill Questions:

• Why do building codes exist?
• Why is ADA important when working with building codes?
• Who is responsible for writing and enforcing building codes?
