Permit for Plumbing Repairs

HOA is shutting off water in a few days to take care of a water line repair due to an active leak. There are 8 buildings that this affects. Do they need to file for a permit before doing this work?

Building department would tell you yes. They want the permit fees.
But you really don't need a permit for every repair. Government inspectors are not really quality control. Their interest is to make sure their rule book is followed. If they are modifying something major, like a gas system, that may become hazardous then a permit might be in order. We used to pull a permit for every water heater replaced but stopped and only do when requested by owner. Most customers if given the choice opt out from paying for a permit.

If the company you hire has a good rep and does work the right way then why get the Government involved. They just muttle it up for you ,sometimes.

Got it. Thanks, Mr David, for your prompt and detailed reply.
