Rockville Plumbing Oversight: WSSC vs. City of Rockville
Rockville is unique because water and sewer oversight depends on the specific property location, not just the city address:
✓WSSC-served properties follow WSSC permitting, inspection, and compliance requirements.
✓ City of Rockville–served properties follow City of Rockville plumbing permits, inspections, and municipal codes.
Important: Using the wrong authority can result in failed inspections or rejected permits. Durance Plumbing routinely works with both WSSC and the City of Rockville and determines the correct governing authority before work begins.
