The Bay Area is making a big change to help the environment, and homeowners need to be ready. Starting in 2027, you won’t be able to buy or install natural gas water heaters anymore. By 2029, natural gas furnaces will also be banned, and by 2031, large commercial water heaters will be included too. If you live in the Bay Area, these rules will change how you replace and upgrade your heating systems.
Why Is This Happening?
- The goal is to reduce air pollution and make the air cleaner to breathe. Natural gas water heaters and furnaces release nitrogen oxides (NOx), which can cause breathing problems and other health issues. Switching to electric water heaters and furnaces will help make the air safer for everyone.
How This Affects You
-
If your gas water heater stops working after 2027, you will need to replace it with an electric model.
-
You can still repair your current gas water heater, but you can’t buy a new gas-powered one after the ban.
-
New homes will only be allowed to install zero-emission electric water heaters and furnaces.
What You Can Do Now
- Check Your Current System – If your water heater or furnace is getting old, consider upgrading sooner so you have more choices and can avoid higher costs later.
- Look Into Electric Options – Heat pump water heaters and electric furnaces are great alternatives. Some may even qualify for rebates or discounts to help with the cost.
- Stay Updated – Keep an eye on information from BAAQMD and local utility companies about new rules and financial help.
- Think About Home Value – Homes with gas appliances may become less desirable in the future. Switching now could make your home more attractive to buyers.

Final Thoughts
This change might feel like a big deal, but planning ahead will help you avoid surprises. If you’re thinking about selling your home in the next few years, upgrading to energy-efficient heating systems could increase your home’s value.
