Building codes regulate what type of glass can go where in a commercial building — mainly to prevent injuries from broken glass in doors, low windows, and other high-contact areas. These requirements generally trace back to nationally adopted model codes, applied and enforced locally, which is why specifics can vary by jurisdiction.
In general, glass in and near doors, glass close to the floor, and glass in other 'hazardous locations' as defined by code needs to be safety glazing — tempered or laminated — rather than standard annealed glass. The exact thresholds and definitions are set by the code edition your locality has adopted.
Code requirements and how they're enforced can differ between jurisdictions and change over time. This article is a general, plain-language overview, not a substitute for confirming requirements with your local building department or a licensed contractor for your specific project.
A glass repair company that regularly does commercial work should be able to tell you, for your specific opening, whether safety glazing is required and can pull permits when needed. That's worth asking about directly before work begins, not after.
