Which of the following is exempt from requiring a permit according to the IRC?

Fences not exceeding 7 feet in height are exempt from requiring a permit according to the International Residential Code (IRC). The IRC generally allows local jurisdictions to regulate the need for permits based on factors such as the height of structures. Typically, low residential fences serve various purposes, including demarcating property lines or providing privacy, and are often exempted because they are considered to have minimal impact on safety or the environment.

On the other hand, structures such as fences exceeding 7 feet in height, new home construction, and major renovations usually require permits due to safety concerns, potential zoning violations, or the need for inspections to ensure compliance with building codes. These activities are often seen as more complex and capable of impacting the surrounding area or existing infrastructure, necessitating the oversight of a permit process.
