Which of the following are considered informal notices?

Informal notices are typically less structured communications intended to advise individuals of potential code violations without the formality associated with official actions. This includes verbal notices, which can be delivered in person or over the phone, informal written notices that may not follow strict formatting guidelines, and courtesy notices that serve as friendly reminders before any formal enforcement actions are taken.

This approach benefits both the enforcer and the recipient by fostering communication and understanding. It allows individuals the opportunity to address potential issues before they escalate to formal violations that may result in legal proceedings or penalties.

In contrast, the other options listed, such as legal summons, formal written warnings, and official code citations, represent formal processes typically reserved for situations where immediate or significant compliance issues exist. These methods carry more serious implications and are part of a structured enforcement workflow, thus not fitting the informal notice category.
