Do you need a permit for a water heater? Unveiling the truth.

If you’re a new homeowner or planning to replace or install a water heater, then you must know the rules of obtaining a permit. Often homeowners aren’t aware that permits are needed before installing or replacing a water heater. However, knowing the rules and regulations of obtaining a permit can save you hefty penalties.

In this blog post, we will discuss the circumstances under which permits are required for installing or replacing a water heater.

Scenario 1: Replacing An Old Water Heater

Are you planning to replace your old water heater with a new one? If yes, then you need to check some things before going ahead with your decision. Here’s what you should do:

If you’re replacing the old unit with a new model of the same type, then you don’t need a permit. However, if you’re making changes in the location or the type of the water heater, then you must take a permit before installing it.

Scenario 2: Installing A New Unit In A New Location

Installing a new water heater in a new location requires a building permit. Here are some points to remember before proceeding with the installation:

  • Check the minimum distance between the unit, walls and ceiling.
  • Get a licensed plumber to inspect the gas or electrical lines before installation.
  • Obtain a permit from the local building authority before installation.

Even if you’re a diy-er, you can’t install the water heater by yourself without obtaining a permit. An authorized inspector will check the installation and approve it. Installing a water heater without a permit can lead to penalties, including the removal of the heater.

Scenario 3: Installing A Tankless Water Heater

Tankless water heaters are becoming increasingly popular amongst homeowners due to their energy efficiency and cost-effectiveness. However, if you’re planning to install a tankless water heater, you should consider some things beforehand:

  • Check the wiring and gas lines before installing.
  • Find an authorized plumber to connect the pipes and install the heater.
  • Obtain a permit from the local authority before installation.

Remember, installing a tankless water heater without a permit can result in fines and penalties. Always take the proper approval before starting the installation process.

The Bottom Line

Now that you know the circumstances under which permits are required, it will be easier for you to avoid costly mistakes during the installation process. Be sure to check with your local building authority before you begin any work to ensure that you’re following the legal requirements.

Objections And Pitfalls Of Not Getting A Permit

If you’re excited about getting a new water heater, you might be thinking about installation and usage, but have you considered whether you need a permit? Here are the main objections against getting a permit and pitfalls of not getting one for your water heater installation.

Objections Against Getting A Permit

  • Excessive time and cost: Applying for and getting a permit can be expensive and time-consuming, especially if you’re in a city with strict regulations. The extra time and money spent on getting a permit may discourage homeowners from pursuing one.
  • Lack of knowledge: Some homeowners may lack the knowledge required to get a permit and fulfill all the requirements for installation. Also, permits vary depending on where you live, which makes it difficult for homeowners to navigate permit requirements in other neighbourhoods.
  • Optional requirement: Permits are not mandatory in all areas, and homeowners may not see the need for one if they’re not legally required to have one to install their water heater.

Pitfalls Of Not Getting A Permit

  • No warranty: Manufacturers require permits to be issued before they can give homeowners warranties. So, without a permit, you’ll be voiding the manufacturer’s warranty, which can have financial implications if your unit requires repairs.
  • Financial penalties: Not having a permit can impact your finances should any issues arise when you try to sell your property. Building inspectors may discover that you installed a water heater without a permit and may require you to pay fines to get your property up to code before selling it.
  • Unsafe installation: While it may be tempting to skip getting a permit for a water heater installation to save money and time, it could lead to unsafe installation if homeowners lack the knowledge to install the unit correctly. This could lead to injury, damage to property and potential legal issues if someone is hurt.
