A construction supervisor license is required for all but which of the following?

A construction supervisor license is not required for swimming pools because the regulations surrounding pool construction often have specific exemptions. Many jurisdictions allow homeowners to construct or install their own swimming pools without the need for a licensed supervisor, especially in cases where the pools are smaller or the installation involves prefabricated kits. This is typically done to encourage personal DIY projects and home enhancements, provided they meet local safety codes and standards.

In contrast, activities such as constructing agricultural buildings, reconstructing doors, and removing roof coverings generally require a license. These activities often involve structural changes, modifications, or work that directly impacts the integrity of a building, thus necessitating oversight from a licensed professional to ensure safety and compliance with building codes.
