Which of the following is NOT a method mentioned for gaining voluntary compliance?

Judicial orders are typically considered a form of enforcement rather than a method for gaining voluntary compliance. They are legally binding decisions issued by a court that compel compliance with regulations or laws, resulting in penalties for non-compliance. The goal of enforcement through judicial orders is often to compel adherence after other less formal methods have been attempted and failed.

On the other hand, the other options represent informal and proactive approaches aimed at fostering cooperation and compliance without resorting to legal action. Informal handwritten notices offer a personal touch to notify individuals about code violations while encouraging them to remedy the situation. Phone calls allow for direct communication that can clarify concerns and prompt action. Public education efforts inform the community about codes and standards to promote voluntary adherence from the start. These methods reflect a collaborative approach, prioritizing dialogue and understanding over strict enforcement measures, which is key in code enforcement practices.
