Water Heater codes & Permits

You may be wondering, “Do I need a permit to replace my water heater in Fremont?”

Currently, Fremont requires a permit is required for a water heater installation. The good news is we can pull the permit for you, and it will not slow down any work on our end.

Every few years, Fremont water heater codes change to adopt new installation and safety measures. While intended to increase your overall home safety, these code requirements can result in extra installation charges.

Some customers scoff at the idea of paying for a permit for a water heater replacement, but the fact of the matter is water heaters can be dangerous if not installed correctly. In fact, water heaters cause more property damage than any other home appliance. And if the unit is not installed to code by a licensed professional and causes damage, your home insurance could reject any claims. That’s why we put a premium on safety and doing everything by the book.

Your expert technician will go over an item-by-item checklist of all applicable safety codes needed for your installation prior to any work being completed, or cost to you.

We try to keep this information as up-to-date as possible, but your Fremont installer will be able to answer any specific question you may have.

Local Water Heater & Plumbing Permits – Fremont, CA

Water Heater Codes Currently Enforced in fremont

  • Approved Location – Generally, water heaters cannot be located in bedrooms, bathrooms or closets (unless the closet is used only for the water heater). This requirement is to avoid accidents and to prevent human contact with minor amounts of CO (carbon monoxide) that discharge from a gas water heater vent. This is currently enforced in Fremont.

    Earthquake Straps – Earthquake straps on water heaters are a requirement as California is an earthquake zone. The straps must go on the top third and bottom third of the water tank. This is enforced by most inspectors in Fremont for your protection.

    Venting – If you have a gas combustion water heater it must be vented properly. This type of water heater generates carbon monoxide (CO) which is part of the combustion process. The vent size must be adequate for the size of water heater you have. If the vent is composed of a substance that heats up, there must be sufficient clearance from flammable or combustible surfaces. This regulation is enforced by Fremont.

    Pans and Drains – If your water heater is sitting on a built-in platform or located in the interior where there is a chance that damage from leaking could occur, you are required to have a pan placed under the water heater with an attached drain line running to the exterior. This is a CA plumbing code requirement which Fremont will enforce.

    Pressure and Temperature Relief Drain (“P&T Drain”) to the Exterior – A California Plumbing Code requirement is that the P&T relief drain is run to the exterior. This will avert the possibility of scalding if someone walks too close to the water heater during the discharging of the pressure and temperature relief drain. Fremont currently enforces this. As well, in some cases, where it is not possible to pipe to the exterior, Fremont permits a Watts 210 valve as a substitute. There are also some cases, if a drain already exists, where the city will allow piping the P&T to a garage floor.

    Dedicated Water Shutoff – The CA Plumbing Code requires a dedicated water shutoff to be installed on the water heater. If the water tank must be shut down for service, the rest of your home will still have water. This code item is actively enforced by Fremont.

    Pipe Insulation – Any pipes which are exposed in unconditioned space must be insulated. This is enforced in Fremont.

    Bonding – A requirement by the California Electric Code states that all gas and water pipes be grounded. All pipes can be correctly grounded using 6 awg wire and clamps. This is a requirement because plumbing located close to electrical wiring may energize your pipes. Fremont Inspectors currently require this.

fremont Water Heater repair

Water heaters are constantly operating, heating and storing hot water for your use. They’re built to last, but if yours starts leaking or you’re out of hot water, you may need to have your water heater repaired.

Typically, a water heater comes with a warranty anywhere from 5-15 years on parts. For this reason, if you start experiencing issues, try to find the model & serial numbers on the rating plate of your water heater so we can determine if it is still under warranty. Our service technicians are local to Fremont and are familiar with most regional heater applications, brands and models.

It’s important to note, if your existing model is more than 10 years old, it’s probably nearing its last legs. Considering the cost of labor, rather than repairing it, a more prudent financial choice might be to just replace the water heater.

In Fremont, common water heater repairs and maintenance include:

    • Replace the thermocouple – Sometimes a fix is as simple as one small part. This is often the case when a water heater isn’t heating water; typically it just needs a replacement thermocouple, which allows the heater to take in gas.


    • Replace the anode rod – Over time, the minerals in your water and pressure in your tank will cause corrosion of your water heater. Anode rods prevent tank corrosion because they attract the corrosive elements, keeping them away from the storage tank. The installation of dual anode rods, or a replacement can extend the life of your heater.


    • Pilot light – This simple mechanism is also responsible for lots of water heater repairs. Sometimes the light can simply go out and just needs to be re-lit. Other times, the assembly has failed, and needs to be replaced.


  • Drain storage tank – Some newer water heaters have self-cleaning tanks, however, older ones need to be manually drained to prevent a sediment build-up. If you fail to drain the sediment, eventually the mineral deposits will collect and shorten the useful life of you water heater.
