Summary

The Building Department, acting under the State Building Code, also charges investigation, reinspection and completion-certificate fees on top of that base permit fee.

Violations & Fines

Occupying or using plumbing work before the required Certificate of Occupancy or Completion is issued can draw a further $200 fee under § 123-5.B, and skipping a Certificate of Completion for more than a year after finishing electrical, plumbing or mechanical work adds another $200 under § 123-5.E.

Frequently Asked Questions

How much does a Stamford plumbing permit cost?
Section 123-3 sets the fee at $10 for every $1,000 of estimated cost, or any fraction of it, with a minimum of $25 no matter how small the job. That fee applies to plumbing work that doesn't already require its own building permit.
What if I do plumbing work without pulling a permit first?
The Building Department can assess an investigation fee under § 123-5.A on top of the regular permit fee. That investigation fee equals the amount of the permit fee that should have been paid, but it can never be less than $200, and it applies whether or not a permit is later issued.
Do I need a Certificate of Completion for plumbing work?
Yes. Under § 123-5.E, if you finish electrical, plumbing or mechanical work performed under a permit but don't obtain a Certificate of Completion within one year of finishing, the Building Department charges an additional $200 fee before it will issue that certificate, on top of whatever the original permit fee was.
Are there fee waivers for city projects?
Yes. Section 123-6 waives building permit fees, which includes plumbing permits, for construction connected to the City of Stamford's own governmental functions, and for non-city entities building projects that are in the city's capital budget and fully funded with city capital funds.
