Permits and local rules for basement waterproofing
Waterproofing and drainage work is often regulated at the city or county level, especially when it involves excavation, a new discharge line, or changes to grading.
Rules differ by place. Some jobs need a building, plumbing or land-disturbance permit; others do not. Ask the contractor what they will pull, and confirm with the local building or permitting office if you are unsure.
Discharge from a sump usually cannot be sent onto a neighbor's property or into a sanitary sewer unless the local code allows it. Get the planned outlet in writing.
Call 811 (or your state's utility-locate service) before anyone digs. A serious contractor will not skip locates.
