Which of the following are considered the two most basic types of signs?

The two most basic types of signs are classified as permanent and temporary. Permanent signs are typically intended for long-term use, serving a consistent purpose such as business identification, regulations, or wayfinding. These signs are often regulated more strictly, as they contribute to the overall aesthetics and functionality of the environment.

On the other hand, temporary signs are used for short-term purposes, such as promotional events, real estate listings, or construction notices. They are generally easier to install and remove, reflecting the transient nature of the messages they convey. Understanding the distinction between permanent and temporary signage is crucial in code enforcement, as it often dictates permitting requirements and compliance with local regulations.

The other options illustrate different classifications of signs that are more specific but do not encompass the fundamental distinction that permanent and temporary signs represent. For instance, lighted and unlighted signs speak to illumination rather than the longevity of the sign, while ground and wall signs refer to their installation methods. Directional and advertising signs pertain to their function, which again does not capture the basic nature of permanence versus temporality.
