Plumbing projects big and small require permits from the city. This ensures that the work done on the plumbing system meets local codes and regulations. Before starting your next plumbing project, look into whether or not you need a permit. The City of St. Louis publishes a full list of guidelines, but since the information is not in an easy-to-read format, we’ll explain the basics below.

When a permit is typically necessary

The following plumbing jobs will usually require a permit:

• Repiping. If your home needs some or all of its plumbing system replaced, you will need a permit before work can start.
• New installations. If a new section of pipe needs to be installed, you’ll also need a permit from the city. An example of this would be if you were finishing your basement and were installing a new bathroom. Also, a permit is needed any time a new feature, such as sink or toilet, is installed.
• Replacing the drain line. If your drain line has ruptured or otherwise needs replacing, you should file for a permit.
• Anything to do with the sewer line. Since the sewer line also connects to a public utility, any work on it will need to be approved by the local government. This makes sure that all safety codes will be followed.
• Moving the plumbing system. If a part of your plumbing system is moved to a different location, it is seen as a remodel and must have a permit.
• Water heater installation. This is a common issue, as water heaters only last eight to 12 years. Once yours kicks the bucket, a permit will be needed before the new one can be installed due to water heater safety regulations.
• Soil stack repair. If your soil stack is damaged or not venting properly, repairing or replacing it will necessitate a permit.

When a permit isn’t necessary

While permits aren’t typically needed for the following plumbing projects, you should still contact the city at 314-622-3313 for verification.

• Repairing or replacing existing features. You should be able to replace accessible plumbing features such as faucets and garbage disposals without a permit provided no additional repair work is required beyond the fixture tubing connections. Remember that large installations such as sinks and toilets do need a permit, however.
• Repairs to piping. If the piping that just needs minor repairs due to leaks, you may be in the clear.
• Installing lawn irrigation. Once the backflow device – which does require a permit – is installed, the rest of your irrigation system can be installed without a permit.

In order to receive a permit as a homeowner, you need to meet certain criteria. If you plan to hire a plumber to do the work, they should be certified by the City of St. Louis. They should acquire the necessary permits before starting the job.
