Taking the Guesswork out of Mixed-Use Building Requirements

Mixed-use buildings, which combine multiple occupancies within a single structure, are common, but determining how to apply their unique set of code requirements can be a daunting task.

To simplify code analysis, this document provides logical, code-compliant steps for key elements of design—such as determining allowable building size, fire separation needs, detailing requirements and the application of special provisions.

With an emphasis on light wood-frame construction in Type III and V buildings, it also includes examples, calculations and sample details demonstrating how to navigate the various code requirements associated with mixed-use projects while maximizing building size and meeting fire and life safety requirements.
