Whether you're swapping out a water heater in your home or rerouting the sewer lines for your business, this guide is for you. We'll walk you through who needs a permit and the types of projects that require one, as well as how the permit process works, and why it's really important to get it right in Plano.

KEY TAKEAWAYS:
Plumbing permits in Plano exist to make sure any invasive plumbing alterations are safe and code-compliant.
You typically need a permit for plumbing jobs that involve installing new devices or altering the flow of water.
Permits aren't usually necessary for small jobs, like replacing a faucet.
A licensed plumber can apply for a permit on your behalf. Only Master Plumbers are allowed to pull permits for the bigger projects.
WHAT DO PLUMBING PERMITS DO?
A plumbing permit is essentially a green light from the City of Plano Building Inspections Department that lets you or your contractor do plumbing work that's safe and up to code. The permit system is designed to make sure all local plumbing installations meet the city's adopted building codes, which in Plano includes the 2021 International Plumbing Code (IPC), with some local amendments thrown in for good measure.
Getting permits might seem like an annoying waste of time, but they play an important role in protecting our city's residents, making sure any plumbing work gets done right. They're not optional: to avoid getting fined or potentially facing problems when you come to sell your home or business, you'll need to get one before starting most types of plumbing work.
WHEN DO YOU NEED A PLUMBING PERMIT IN PLANO?
In Plano, most plumbing work requires a permit. According to the city's permitting information, permits are required for projects that involve:
Hooking up, replacing, or rearranging water lines or sewer lines
Installing or swapping out water heaters, water softeners, or other plumbing gear
Adding new plumbing fixtures or systems that change the way water flows in your house
Doing some major repairs that modify or replace sections of existing pipes
The City of Plano's "When Do You Need a Permit?" guidance makes it pretty clear that any work that involves plumbing, water heaters, or softener devices is going to need a permit. The good news is that the more simple tasks, like swapping out faucets, generally don't.
As a simplified summary, if your project involves changing the flow of water or installing new plumbing components, there's a good chance a permit is needed.

WHO SHOULD APPLY FOR A PERMIT FOR PLUMBING IN PLANO?
When you're getting plumbing work done in Plano, it's usually the licensed plumber doing the work who applies for the permit, or, in some cases, the homeowner if the city allows it. All licensed plumbers in Texas have to have a valid license from the Texas State Board of Plumbing Examiners, so you can be sure they're qualified to do the job. And only certain license types, like Master Plumbers, are allowed to pull permits for the bigger projects.
At Military Plumbing, our business is owned and operated by a Master Plumber, which means we're able to apply for any type of residential or commercial permit needed for your project. Find out more about our services or contact us to get started.

If you're not sure whether your project needs a permit, it's always a good idea to check with the Plano Building Inspections Department or have a look at the permit guidelines online before you start work.
PROJECTS THAT USUALLY DON'T NEED PERMITS
According to Plano's permit guidance, most minor or cosmetic jobs don't usually need a plumbing permit, such as:
Swapping out faucets similar basic fixtures
Doing small repairs that don't change the plumbing setup
That said, even a simple job like this can sometimes require a permit if it involves moving pipes or extending your plumbing in a way that changes its layout. If you're not sure, it's always best to check with the city's permit office, or ask a knowledgeable local plumber like the team at Military Plumbing.
HOW TO GET A PLUMBING PERMIT IN PLANO
Plano's permitting system is run by the Building Inspections Department. You can either apply for a permit online or in person, and the process generally looks like this:
Fill out the plumbing permit application and gather all the project details you need.
Submit your application online and provide the required documents. You can submit and track many types of building permits by creating an account on Plano's eTRAKiT system.
Pay the fees. Plumbing permit fees depend on the project type and size (for example, residential permits often have a minimum fee of around $45).
Schedule inspections at the required stages after work begins until it's complete.
You'll find all the contact and permit application details on the official Plano Permits & Licensing page.
In most cases, you won't need to apply for a permit at all, as your plumber should do this for you. If a permit is needed, we'll make sure you get one, so it's nothing you need to worry about obtaining yourself.

WHAT TO KNOW ABOUT PERMIT INSPECTIONS
When you get your plumbing permit, city inspectors will visit your property at various stages of the project to make sure everything is up to code. This will probably involve at least a couple of inspections:
A rough-in inspection (i.e. before they close up the walls)
A final inspection (once all the work is done)
If you fail an inspection, it can hold things up, and your plumber might need to make some corrections before you can carry on. You can avoid this by working with a plumber who's familiar with the Plano code and can handle everything for you, like our plumbers at Military Plumbing.
FINAL TIPS FOR PLANO HOMEOWNERS

FAQ
WHY DO YOU NEED A PERMIT FOR PLUMBING WORK IN PLANO?
You need a plumbing permit in Plano to ensure any work done in your home or business meets local and state plumbing codes. Aside from simply being an essential legal requirement, this helps protect your property's water quality and overall health and safety, as well as preventing delays to your project. When you have the right permit for the job, you'll also be protected from potential issues with insurance or resale problems caused by unpermitted work. At Military Plumbing, we obtain permits whenever structural alterations, remodels, or replacements are required in a plumbing system, and we'll only begin work when a permit is approved.
HOW LONG DOES IT TAKE TO GET A PLUMBING PERMIT IN PLANO?
The wait time to get a permit approved depends on the complexity of your project, as well as how busy the City of Plano Building Inspections Department happens to be at the time of your application. If you're getting a simpler job done, like swapping out a water heater, your permit might get approved on the same day if you don't need to submit any plans. But complex projects that need a more detailed plan review can take a few days to get sorted.
HOW DO I KNOW IF MY PLANO PLUMBING WORK REQUIRES A PERMIT?
The best way to know whether your Plano plumbing project requires a permit is to contact a licensed local plumber and ask them. The City of Plano website has contractor registration forms that allow contractors to register for all manner of plumbing, mechanical, electrical, roofing, and other building permits, so whether they're building driveways, installing pools, or constructing something small like a shed, they can usually navigate the complete application process on your behalf. Our business is owned and operated by a Master Plumber, so we're allowed to apply for any type of permit needed for your project for convenience and efficiency.
WHAT IF MY PLANO PLUMBING PERMIT EXPIRES?
In Plano, a plumbing permit typically expires if work doesn't begin within 180 days of when it was issued, or if the project is suspended or abandoned for 180 days after work has started, in line with the city’s adopted building code provisions. If you apply for a permit that expires, you might need to request an extension or apply for a new permit before you can continue work.
