The California Air Resources Board adopted a rule that will effectively prohibit the sale of new natural gas-powered water heaters by 2030. The Bay Area is applying even tougher regulations in which the new standards can come as early as 2027. If you are a homeowner in San Jose, this policy might affect you directly, so here is everything you need to know about the gas water heater ban.

California Gas Water Heater Ban: New Rules in San Jose Starting 2027
As a resident of California, you are undoubtedly already aware that a statewide mandate for greener energy was issued that is set to abolish the sale of new gas space and water heaters by 2030. The Bay Area Air District (BAAD) has taken the matter of a zero-emission future even further. The homeowners in San Jose and nearby areas will face the new regulations —or the California gas water heater ban as it was called in the media — even earlier — starting January 1, 2027. See the table below to learn what it means for you.
Timeline — When Gas Water Heaters Will No Longer Be Allowed
| Year | What changes | What you can do | What you can’t do |
| 2026 | This is the final year before stricter emissions standards take effect for new water heaters in the Bay Area. | Repair or replace your gas water heater as well as install a new one. | Delay planning if your system is nearing the end of its lifespan. |
| 2027 | Bay Area Air District zero-NOx standards take effect for newly sold and installed water heaters, limiting gas options for new installations. | Keep your old natural gas heater if it is still in good condition or replace it with a heat pump or compliant gas water heater. | Install a newly manufactured non-compliant gas water heater. |
| 2030 | Statewide zero-emission standards for new residential water heaters take effect in California. | Continue maintaining an existing gas water heater or replace it with an electric one. | Purchase or install a newly manufactured natural gas water heater that does not meet requirements. |
What If You Already Have a Gas Water Heater Installed
If your home is equipped with a natural gas water heater, it is time to decide whether you want to wait for it to die or replace it now. It depends on several factors:
- Age of the system — if it is older that 5 years old, it might be wise to replace it now;
- Performance of the heater — units that receive regular maintenance are likely to last longer;
- Type of the appliance — it can be tank or tankless.
When making a decision, keep in mind that starting 2027 water heater repair technicians will have difficulty finding the correct parts as most manufacturers will focus on electric models. And if it comes to replacement, that will be met with such obstacles as contractors’ unavailability, longer wait times and higher costs.
Why Replacing Later Will Likely Cost More

Waiting till the gas water heater ban comes into effect to replace your old unit will cost you more (and not just in financial terms) due to several factors:
- High demand. With people rushing to replace their outdated system, the cost for the equipment as well as labor is likely to go up.
- Emergency uncertainty. Last-minute gas replacements may be restricted or unavailable due to new laws.
- Rebates deadlines. You may miss out on current rebates that can save you thousands of dollars today.
Available Incentives for San Jose Homeowners
State and Utility Rebates
Many local utilities offer heat pump rebates between $750 and $1,500 that can and should be combined with other incentives. For more information on it contact your utilities provider.

Why Heat Pump Water Heaters Are the Smart Replacement
While incentives are still in play and there isn’t a high demand, it would be wise to upgrade to a heat pump water heater. Here are the core reasons to do so:
- Get your home future-ready: switching to a heat pump water heater today makes sure your home will be fully compliant with upcoming laws.
- Expand your savings: programs described above offer thousands of dollars to help homeowners with the financial issues of replacement.
- Step into energy efficiency: Heat pump technology is up to 4x more efficient than gas and will significantly reduce not just your home’s carbon footprint but also long-term energy costs.
As the 2027 Bay Area gas water heater ban nears, equipment shortages and increased labor costs are highly likely due to high demand. Getting a water heater installation in Santa Clara and surrounding areas now guarantees a fast and easy process and the best cost.

What Homeowners in San Jose Should Do Now
As evident from above, if you have a natural gas water heater, now is the time to act to avoid the rush and make sure you comply with the new regulations.
Parts Crisis
The parts for repairs will become scarce from next year on. That means if your appliance breaks in the middle of the winter, you will have to rush the replacement decision.
Replacement Issues
The replacement of such units will not be difficult as well. You will be able to install a new heat pump water heater, but if you decide to get another gas one, you won’t be able to.

To not get left without hot water in the most inconvenient moment, consider switching to the greener option already now. We at Fuse Service can help you make it possible with a heat pump water heater installation at any time.
