The Uniform Building Code (UBC) was a comprehensive model building code adopted by many jurisdictions to regulate structural design, fire safety, and construction materials. It was particularly known for its rigorous seismic design requirements. The UBC was eventually merged with other regional codes to form the International Building Code, but veterans still reference its standards when dealing with older structures.
