Are Generators Banned in California in 2026?

Are Generators Actually Banned in California?

No. A more accurate description is that California is progressively tightening emissions standards for certain new small spark-ignition engines, including many portable generator engines.

The distinction between an emissions standard and a use ban matters. A headline saying "California bans gas generators" can leave homeowners thinking that running a generator they already own has become illegal. That is not what CARB's current SORE regulations say.

There is also very concrete evidence that the 2026 market has not been shut down: CARB's model-year 2026 certification records include Executive Orders for equipment identified as Generator Set.

What Does California AB 1346 Actually Say About Generators?

California's generator-ban discussion usually starts with Assembly Bill 1346, signed in October 2021. The law added Section 43018.11 to the California Health and Safety Code.

AB 1346 directed CARB to develop cost-effective and technologically feasible regulations intended to prohibit exhaust and evaporative emissions from new small off-road engines. It did not simply declare that every gasoline generator would become illegal on a particular day.

The law also specifically required CARB to consider the expected availability of zero-emission generators and emergency response equipment when determining technological feasibility.

AB 1346 and the CARB Regulations Are Not Exactly the Same Thing

This is one reason online explanations often become confusing. AB 1346 is the legislation directing CARB to establish regulations. CARB's adopted SORE regulations contain the actual emissions standards, applicability rules, certification procedures, phase-in dates, and exemptions that manufacturers and equipment must follow.

For portable generators, CARB did not impose the same 2024 zero-emission schedule applied to many smaller lawn-and-garden engines. Portable generator engines received a later transition because emergency-power availability and technological feasibility are materially different from replacing a leaf blower or string trimmer.

Can You Buy a Gas Generator in California in 2026?

Yes. The important question is not simply whether the generator burns gasoline. The question is whether a new generator that is subject to California emissions regulation has the required California certification.

CARB states that new engines and equipment subject to its certification programs may be sold in California only after approval through an Executive Order where required. For small portable generators, product listings commonly describe qualifying units as "CARB compliant," "CARB certified," or "California legal."

How to Check a Generator Before Buying

1. Confirm the product is specifically approved for California sale. Do not assume an EPA-certified model is automatically California-certified.
2. Check the exact model, engine family, and configuration. A manufacturer may sell several visually similar versions with different certifications.
3. Look for the California emissions label. Keep the label intact along with the owner's manual and purchase records.
4. If the seller's listing is unclear, verify the CARB Executive Order. CARB publishes certification records by model year.
5. Be cautious with out-of-state purchases. Buying a non-California-certified new generator elsewhere does not automatically make that configuration compliant for California sale or introduction.

Which Types of Generators Are Affected by California's SORE Rules?

Another reason the phrase "generator ban" is misleading is that California does not regulate every generator under one single rule.

SORE generally covers spark-ignition engines rated at or below 19 kilowatts, or 25 horsepower. Portable generators are a common SORE application. CARB separately identifies diesel engines and stationary equipment as outside the SORE regulations.

Are Propane Generators Exempt From the California Generator Rules?

Not automatically. This is one of the most persistent oversimplifications in older generator-ban articles.

The SORE program is centered on qualifying spark-ignition engines, not simply the word "gasoline." CARB's rulemaking record specifically addresses propane-fueled SORE generators rather than treating every propane portable generator as categorically outside the regulation.

That means switching from a gasoline-only portable generator to a propane or dual-fuel portable generator does not, by itself, guarantee that the equipment is outside California's SORE requirements.

This is different from a stationary propane standby generator. Stationary generators are outside the SORE program, although installation and operation may still be governed by other rules.

Can You Keep Using a Gas Generator You Already Own in California?

Under the SORE regulations, yes, existing CARB-compliant equipment can continue to be owned, used, and repaired.

CARB expressly states that its new emissions standards apply to new engines and do not prohibit possession, use, or repair of existing compliant SORE equipment. California residents and businesses may continue using and repairing that equipment through its service life.

CARB also says stores may continue selling engines and equipment that were manufactured under valid CARB certifications.

This means the transition to the MY2028 standard should not be understood as a state order requiring homeowners to turn in, destroy, or stop repairing every older portable generator.

But "Legal to Own" Does Not Mean "Legal to Operate Anywhere"

Your generator can be compliant under statewide SORE regulations while its use at a particular place or time is restricted for an entirely different reason.

For example, a local fire authority may limit generator operation during extreme fire conditions, a local air district may have rules for larger equipment, and cities or private communities can have separate noise or property-use requirements.

What Actually Happens to Portable Generators in California in 2028?

Under CARB's current public rules, model year 2028 is the major transition point for covered portable generator engines.

CARB's implementation schedule shows portable generators receiving more stringent, but non-zero, emissions standards for model years 2024 through 2027. Beginning in MY2028, the exhaust and evaporative emissions standards for covered portable generator engines move to zero.

Why "All Gas Generators Are Banned January 1, 2028" Is Too Simplistic

There are four separate details hidden behind that headline.

CARB also built a technological-feasibility review into the generator transition process. Because regulations can be amended, anyone planning a major purchase close to the 2028 model-year transition should verify CARB's current SORE page instead of relying on an article written several years earlier.

Can You Use a Generator During a California PSPS?

Yes, CARB regulations allow backup-generator use during a Public Safety Power Shutoff.

This distinction is especially important in California because portable generators are often purchased specifically for wildfire-season outages and utility-initiated PSPS events.

CARB's emergency backup generator guidance says its regulations allow backup generators to be used during PSPS events. For large equipment, CARB advises contacting the applicable local air district to determine whether permitting requirements apply.

For a complete household preparation process, read the California PSPS 2026 Guide.

California Generator Safety Rules That Matter More Than the "Ban"

For a homeowner dealing with a real blackout, where the generator operates can be more immediately important than the emissions debate.

The California Department of Public Health warns that gasoline, propane, charcoal, and other fuels can produce carbon monoxide. Carbon monoxide is invisible and odorless, and dangerous concentrations can build up when combustion equipment is operated in or too close to a building.

Five Safety Questions to Answer Before Relying on a Fuel Generator

1. Can you place the generator outdoors at least 20 feet from windows, doors, and vents?
2. Can exhaust be directed away from the home and neighboring occupied spaces?
3. Is the area clear of dry vegetation and other fire hazards?
4. Do you have working carbon-monoxide detectors?
5. If you plan to energize household circuits, has the transfer equipment been designed and installed correctly rather than using dangerous backfeeding?

Never attempt to power a home by plugging a generator into a normal wall receptacle. Improper backfeeding can energize wiring unexpectedly and create a potentially deadly hazard for utility workers, residents, and equipment.

How Much Battery Backup Do You Need Instead of a Generator?

This is where many comparisons between generators and portable power stations go wrong. Maximum output in watts tells you what the battery can run. Battery capacity in watt-hours tells you approximately how long it can run.

For practical UDPOWER outage planning, a conservative estimate can use about 90% of nominal capacity to account for conversion losses:

Using that planning assumption, the approximate runtimes look like this:

These are planning estimates rather than guaranteed runtimes. Refrigerator compressors cycle on and off, startup power can differ from running power, battery temperature matters, and inverter losses vary with load.

Why This Matters During a California PSPS

A 2,000W appliance may technically fit within a larger power station's output limit but consume a 2,083Wh battery very quickly. During an uncertain PSPS, using stored energy on high-wattage heating or cooking loads may leave less power for refrigeration, communications, lighting, or medically important equipment later.

A stronger outage strategy is to calculate the watt-hours required by your essential loads first and treat discretionary appliances as secondary.

Generator vs. Portable Power Station in California: Which Makes More Sense?

The California rules do not mean every household should immediately replace a fuel generator with a battery. These technologies solve different problems.

Choose a Fuel Generator When

You need extended high-output operation, have a genuinely safe outdoor location, can maintain adequate fuel, and have confirmed that the generator and installation comply with the applicable California and local requirements.

Choose a Portable Power Station When

Your priority is quiet indoor backup for selected essentials, you want to avoid fuel storage and exhaust, or your property does not offer an appropriate outdoor generator location.

Consider a Layered Backup Plan When

You live in a California area where PSPS events or wildfire-related outages can last longer than expected. A battery can handle immediate indoor essentials quietly, while another safe recharge or backup source can extend resilience if the outage continues.

2026 California Backup-Power Buyer Checklist

1. Start with the outage, not the product. Decide whether you are preparing for a two-hour blackout, overnight PSPS, multi-day wildfire outage, RV trip, or jobsite use.
2. List essential devices. Write down their running watts, startup watts where applicable, and expected hours of operation.
3. If buying a combustion generator, verify California certification. Do not rely only on the seller saying "EPA compliant."
4. Check whether the generator is portable, stationary, spark-ignition, diesel, or another configuration. These categories do not all fall under the same CARB rules.
5. Confirm safe placement before purchasing a fuel generator. California health guidance calls for at least 20 feet of separation from windows, doors, and vents.
6. Check local restrictions. Fire conditions, air-district rules, permits, electrical requirements, and local noise rules can matter independently of CARB's SORE program.
7. For a battery system, calculate watt-hours as well as watts. High inverter output does not guarantee long runtime.
8. Add a reserve. California PSPS restoration may take longer than your initial estimate because utilities may need to inspect lines before re-energizing them.
9. Plan recharging. Solar can extend runtime, but clouds, wildfire smoke, shade, temperature, and limited daylight make theoretical panel output a poor guarantee.
10. Recheck CARB before the MY2028 transition. Regulations and certification details can change, so use the current official CARB page when making a future purchase.
