What is NOT typically considered a violation under building regulations?

The correct choice identifies proper posting of permits as not typically considered a violation under building regulations. Building codes and regulations generally focus on the structural integrity, safety, and compliance of construction projects. While permits are essential for legalizing construction activities and ensuring oversight, the act of properly posting these permits does not in itself constitute a violation. Instead, it is a requirement that helps authorities confirm that a project is authorized and adheres to applicable regulations.

In contrast, non-compliance with safety codes, failure to complete a project, and unapproved modifications all represent violations of building regulations because they directly affect safety and compliance. Non-compliance with safety codes can endanger public safety and is often monitored closely. Failure to complete a project can lead to issues of safety, abandoned structures, and neighborhood blight, which are seen as detrimental to community standards and expectations. Unapproved modifications can compromise the original design intent and safety parameters, making them a serious violation as well. Each of these choices impacts the integrity and safety of the building environment, while proper permit posting serves more as a compliance measure rather than an infraction.
