Foundation work in Warren
Warren's 2025 plumbing permit application prices "Basement Waterproofing" at $80, a sump and sump pump at $25 and a backwater valve at $10, with an $80 minimum permit. That makes waterproofing a permitted item here. The city's building-permit list names additions, alterations and basement finishes, not foundation repair, so ask the Building Division which permit your job needs. The Building Division is at One City Square, Suite 305 (an address we confirmed only through a third-party guide), and the building application lists 586-574-4504.
The city warns that work done without permits may bring fines up to $1,000.
