ASCE 7-22 does not feature a standalone chapter titled "Portable Structures". Instead, it classifies all physical entities under standard building types or "Other Nonbuilding Structures". Under , a temporary structure is typically defined as any building erected for less than 180 days .

If your portable unit is going to a location with a wind speed of 140 mph or greater (e.g., Florida or Texas coastline), ASCE 7-22 requires protection against windborne debris.

Portable and relocatable structures were once viewed as a niche subset of temporary construction, often subject to loose local interpretations or reduced loading requirements. However, modern portable structures—such as modular school classrooms, multi-story construction site offices, containerized data centers, and medical clinics—perform exactly like permanent facilities. asce 7 22 portable

The standard also addresses (Chapter 13) and non‑building structures similar to buildings (Chapter 15), both of which are directly relevant to portable and prefabricated systems.

Chapter 11 of ASCE 7‑22 sees significant changes, particularly in site classification and coefficients for seismic response. The new data simplifies site‑specific analysis and works seamlessly with the portable Hazard Tool mentioned above.
