What Types of Plumbing Projects Require Permits?

Posted on 2 June 2020

Any time you're going to be getting some plumbing projects done at your home, it's important you take out the proper permits for the job. Homeowners often mistakenly believe permits are only required for major remodels that involve structural changes, but this isn't necessarily true. In some cases, some small plumbing projects you might not think require permits will actually require you to get the proper permission from your local government. And you can always assume larger plumbing projects will require a permit before you actually start any of the work.

How do you know if a permit is required?

A professional plumber will always know when a permit is required for a job, because part of their job is to be fully informed of all local and national plumbing codes and to stay on top of any regulatory changes that occur. This is one of many reasons why it's in your best interest to work with a professional plumber on any kind of job you're taking on.

If you attempt to DIY a project, you must carefully and thoroughly read through all of the local building and plumbing codes and any other national regulations that may affect the job. These codes are here for public safety - you should not flout the codes just because it's inconvenient to get the permits, or because they don't allow you to complete the job you have in mind.

Here are just a few examples of some of the kinds of jobs that are most likely to require you to get permits:

Replacing drain lines

Drain line replacement is a pretty significant job, and you can expect to have to take out a permit to get it done.


Some older homes might need complete pipe replacement depending on the materials or condition of the pipes. When this job occurs, you will also have to change out all the water supply pipes. This is a significant job that will require a permit, and should always be done by a professional plumber given the sheer scope of the job and the level of difficulty involved.

Replacing a water heater as part of a renovation

The process of replacing a water heater is governed by numerous safety, gas and/or electrical regulations you must observe.

Sewer line work

Any kind of work involving sewer lines will have permit requirements because there are a number of safety codes you must comply with.

Moving plumbing fixtures

Maybe you're not fully repiping the home, but you are moving existing plumbing fixtures to another area as part of a home renovation or remodel. This is a common process included in kitchen and bathroom remodels. In such a case, you'll need to take out a permit to get the job done.
