Which type of permit is necessary for construction or any activities that might affect existing structures?

The necessary permit for construction or any activities that might affect existing structures is the renovation permit. This type of permit specifically addresses work that involves modifications, changes, or improvements to existing buildings or structures, ensuring compliance with building codes and regulations. It is crucial for maintaining structural integrity and safety during projects that could impact existing conditions, whether through renovations, repairs, or significant updates.

In contrast, a site development permit primarily focuses on the land use aspects and the overall layout of a development, including site grading and drainage, but does not specifically address the alterations of existing structures. An accessory permit is typically related to smaller, supplemental structures or features on a property, like sheds or fences, and does not encompass substantial work on existing buildings. An alteration permit, while similar in function to a renovation permit, generally refers to alterations that are less extensive in scope, thus not covering the full range of activities that could significantly impact a structure.
