ASCE 7-16 vs. ASCE 7-22: What Changed? (2026)
ASCE 7-16 vs. ASCE 7-22 — key changes including new tornado loads, plus why the adopted building code determines which edition applies.
ASCE 7-16 vs. ASCE 7-22: What Changed? (2026)
Direct answer
ASCE 7-22 is the 2022 edition of ASCE 7 (Minimum Design Loads and Associated Criteria for Buildings and Other Structures); ASCE 7-16 is the 2016 edition it supersedes. The most-cited change is a new tornado load chapter for certain risk categories and regions, alongside updates across wind, seismic, snow, and flood provisions. Which edition legally applies is set by the building code your jurisdiction has adopted — a newer standard doesn't govern until the adopted code references it. Confirm with your AHJ.

Why the edition question comes first
Don't start from "which is newer" — start from "which does my adopted building code reference." That is what legally applies. Only then compare provisions.
Read the standard
These are edition-level orientation notes, not design values. Every governing number and trigger must be read in the ASCE 7 edition your jurisdiction has adopted, and confirmed with your AHJ.
Frequently asked questions
What is the biggest change in ASCE 7-22?
The most widely noted addition is a dedicated tornado load chapter, requiring tornado loads for certain risk categories in defined regions — a first for the standard. There are also updates across wind, seismic, snow, rain, and flood provisions. Read the standard for exact requirements rather than relying on summaries.
Which edition do I have to use?
The one referenced by the building code your jurisdiction has adopted. For example, a jurisdiction on IBC 2018 references ASCE 7-16, while newer code cycles reference ASCE 7-22. A newer standard does not automatically govern — confirm the adopted code with your AHJ.
Do tornado loads always control the design?
No. Where they apply, tornado loads are checked alongside other lateral loads, and wind or seismic may still govern depending on the structure, region, and risk category. The provisions define where tornado loads must be considered, not that they always dominate.
