Most cities and counties require permits for demolition and excavation due to safety, environmental, and zoning regulations. Requirements vary, so it's important to check with local authorities before starting.

Demolition debris is typically sorted on-site and hauled to designated facilities. Materials like concrete, metal, and wood are often recycled according to local regulations.

A demolition contractor is responsible for safely tearing down buildings, structures, or parts of a site. This includes planning, site prep, structural removal, debris cleanup, and proper disposal or recycling of materials.
