Legend: Understanding text markup in codes

This markup broadly applies to the International Codes, but amended codes may have differences. Check the title’s preface to see additional markup guidance.

Changes to code titles are indicated with different visual markup on or next to the text of the section:

  • Blue Text: Technical code changes from the previous edition of the International Codes are shown in blue text. This is an example of a technical change.
  • Red Text: National (outside the U.S.) and state amendments and errata to the International Codes are shown in red text. This is an example of a country, state and errata amendment.
  • Fuchsia Text: City or local amendments and errata to the International Codes are shown in fuchsia text. This is an example of a city or local amendment.
  • Deletion Marker (): Deletion markers are provided in margin where an entire section, paragraph, table or exception has been deleted from the prior cycle of the title.
  • Relocation Marker (*): Single asterisk indicates text or table has been relocated within the code. Full relocation table listed in preface.
