UNDERSTANDING USE & OCCUPANCY

In this series we talk about how we categorize buildings based on purpose, work examples, and look at the downstream code implications for those decisions. What's the difference between use and occupancy? How do we approach mixed-occupancy buildings? We cover this and more in this series.
Our objectives include:
- Understand the difference between use and occupancy.
- Be able to assign an occupancy to a building.
- Understand the implications of each of the three different mixed-occupancy building designations.
