Do I Need a Permit to Install a Sump Pump? in Verenigde Staten
Sump pump installation sometimes requires a permit. Placing a sump pit and pump inside an existing basement may be exempt in many areas, but connecting the discharge to a storm sewer, modifying the foundation slab, or routing new plumbing lines typically triggers a plumbing or building permit.

Country-specific detail
US permit requirements for sump pump installation vary by jurisdiction. Many municipalities exempt a basic interior sump pit and pump replacement from permitting when no new plumbing connections are made. However, most require a plumbing permit when the discharge connects to a storm sewer or when the foundation slab is cut. Discharging sump water into the sanitary sewer is prohibited by the IPC and most local codes — violations can result in fines. Some cities also regulate where the discharge can surface on the property to prevent neighbor flooding. A check valve (backwater valve) on the discharge line is required by code in most jurisdictions.
