What does R703 stand for?

R703 refers to the section of the building code that establishes standards for exterior covering materials and systems applied to walls. This includes various types of materials such as siding, stucco, and other veneers, focusing on aspects like performance, installation, and moisture protection. The standards outlined in R703 help ensure that exterior wall coverings comply with safety, durability, and aesthetic requirements, contributing to the overall integrity and appearance of the building.

The context indicates that options specifying roof structures, wall covering standards exclusively, or foundation design do not align with the specific focus of R703 on exterior wall coverings, which is why they are not correct.
