• B. No
• C. Only if copper
• D. Only in commercial

Answer: (A)

You need a permit to replace the water service. The service line from the public main to the building is part of the potable water system and must be installed and tested to code. The permit process lets the local authority review the plan and inspect the work to ensure proper materials, correct connections, and safe installation of valves, curb stops, and backflow prevention if required. It also covers trench depth, backfill, and restoration after digging. The requirement applies regardless of material used or whether the job is residential or commercial. Skipping the permit can lead to fines, stop-work orders, or having to redo parts of the work to meet code.
