What type of construction work requires a permit?

Permits are typically required for construction work that significantly alters the structure, such as substantial cutting of walls, which falls under option B. This type of work can affect the integrity of a building, potentially altering load-bearing elements, plumbing, electrical systems, or overall safety. Therefore, obtaining a permit ensures that the work complies with local building codes and regulations, which ultimately protects the health and safety of the occupants and the general public.

New constructions also require permits, but not all types of repairs do. Exterior painting and lawn maintenance generally do not require permits because they do not involve significant alterations to the structure or property that could compromise safety or code compliance. Repairs that involve only minor work, like cosmetic updates, also often do not necessitate a permit.

Thus, the need for a permit is primarily linked to the scale and impact of the construction work being performed, making option B the correct choice since it indicates substantial changes that could have significant implications.
