Which of the following activities does not require a permit?

The selection indicating that all listed activities do not require a permit highlights the nature of certain projects in construction and building maintenance. Generally, minor activities such as painting, papering, and tiling do not drastically alter a building's structure or functionality; therefore, they are typically exempt from requiring a permit. These activities are considered straightforward maintenance tasks that don't impact building codes or safety.

Similarly, non-fixed and movable fixtures are items that are not permanently affixed to the premises, again minimizing alterations that would necessitate oversight or safety compliance checks. This category includes furniture, equipment, or other items that can be easily relocated.

Temporary motion picture sets also usually do not require a permit, especially if they do not involve significant construction work, permanent alterations, or extensive power and resource consumption. Most jurisdictions allow for temporary structures designed for special events or productions without needing advanced approval unless they meet certain conditions.

In summary, all these activities are classified as low-impact and do not intervene with essential structural elements of a building, justifying the conclusion that permits are not required for them.
