Plumbing permits must be obtained through the Environmental Unit prior to the start of work.

Plumbing system installation inspections are made when plumbing systems are installed in all new homes or businesses or when plumbing systems are altered in existing homes or businesses.

A permit to do such plumbing work is required to be obtained from our department.

A registered plumbing contractor will determine the number of fixtures needed and will obtain a permit based on this information (see Plumbing Fees). 

Residential plumbing work

Residential Plumbing

The plumbing contractor or homeowner (that lives at the residence) can submit a plumbing application with applicable fees before obtaining a permit.

Homeowners may obtain plumbing permits in order to conduct their own plumbing installations, however, it is our professional opinion that with all of the detailed code requirements, it is often best to hire an experienced plumber.

Commercial Plumbing

Prior to obtaining a Commercial Plumbing Permit, you must submit two sets of building plans designed by a professional engineer or architect.

Upon receipt, your plans will be logged and then assigned to the plumbing inspector.

Once the plans are reviewed, you will be notified whether your plans are in compliance or additional information is needed.


Submission of all items at the same time is essential in order to prevent delays in the review.

After plan approval, the application may be made for a fee to obtain a permit. A plan review fee is charged as part of the plumbing permit fee.

After the plans have been received, they will be reviewed within 30 days. This applies to new or remodeled plumbing. Plans are reviewed in the order they are received or resubmitted. If your plans are incomplete or disapproved, the 30 days begins again after the necessary information or revisions are received.

Please be aware that projects involving Food Service or Retail Food require a Wayne County Health Department Environmental Health Specialist approval before a plumbing permit will be issued.
