Waiting Could Cost You Thousands
After the new rule takes effect, many Bay Area homeowners may need to move to electric or heat pump water heater options — and the installation may require more than just swapping the tank.

The difference could cost you
significantly more.
Every home is different. But for many homeowners, waiting until after the rule change may mean more installation requirements, more planning, and more cost.
Harris can help you compare both paths.
We’ll review your current water heater, explain what the rule may mean for your home, and help you decide whether replacing now or planning for electric later makes more sense.
Don’t wait until it is too late — or too expensive.
Schedule a free consultation and find out whether replacing your gas water heater before the new rule takes effect may be the more cost-effective option.

Gas Water Heater Installations Are Going Away in the Bay Area
This is a new Bay Area regulation. After January 1, 2028, homeowners will lose the option to install a new standard gas water heater.
01
What’s changing
Bay Area regulators are banning new gas water heater installations starting January 1, 2028.
02
Who it affects
If you have a gas water heater, this affects your next replacement decision.
03
What’s not changing
You can keep using your current gas water heater. The rule applies to new installations only.
If your water heater is nearing the end of its life, replacing before 2028 may let you stay with gas for the next 10 years. Harris can help you understand your options before the window closes.
Your Timing Matters
How Old Is Your Water Heater?
Gas water heaters last 10 years. Your unit’s age determines whether this rule matters now, later, or simply as something to be aware of.
0–3 yrs
Newer Unit
No immediate action needed. You should know the rule is coming, but replacement is likely years away.
4–6 yrs
Plan Ahead
Your unit is mid-life. There is no immediate urgency, but the window to choose gas is open now.
7–9 yrs
Consider Replacing
Your unit is getting close to its expected lifespan right as the gas option is going away.
10+ yrs
Replace Now
Your unit is at or beyond the typical replacement age. Waiting may limit your options after 2028.
