A short pipe move or fixture change may still alter plumbing that the municipality expects to review. The current municipal rules and actual drawings or scope control the answer.
Check the exact alteration
- Is a fixture being added, removed or relocated?
- Are water, drain or vent lines being altered?
- Does the work affect a condominium common element or shutdown?
- Is the plumbing part of a larger building-permit application?
- What drawings, data sheets or licensed-trade information does the municipality request?
How Raccoon Plumbing can assist
For accepted work, Raccoon Plumbing can help define the plumbing scope, identify project information and support the plumbing portion of an application. This does not guarantee that a permit is required or not required, that submitted documents are complete for every municipal department, or that approval will be granted.
