Can you put a storage building on a leach field?

No, you cannot put a storage building on a leach field. Leach fields are designed for the proper dispersal and treatment of wastewater, and placing a structure on top can damage the system, impede its function, and violate local regulations. It's important to keep the area above a leach field clear to ensure proper air circulation and maintenance access. Always consult local building codes and regulations for specific guidelines.
