California Cannabis Possession Limits: How Much Is Legal At Home?
If you are 21 or older, California cannabis possession limits at home are clear under Prop 64: you can legally have up to 28.5 grams of flower, 8 grams of concentrate, and grow up to 6 plants for personal use. Everything in this guide builds off those three numbers.
Home vs Public Possession: Why The Location Matters
Most adults know cannabis is legal in California, but many mix up the rules for home and public possession. The statewide limits for adults 21 and over are:
- Up to 28.5 grams (about 1 ounce) of cannabis flower
- Up to 8 grams of concentrated cannabis (vape oil, wax, shatter, rosin, etc.)
- Up to 6 living cannabis plants per private residence
Those numbers apply both at home and in public for what you can legally possess. The big difference is where you can use and store it:
- You may use and store cannabis on private property, subject to landlord or HOA rules.
- You may not smoke or vape in public places or anywhere tobacco is banned.
- You may not have open containers in a vehicle unless they are in the trunk.
So the “how much weed can you have in California” question has two parts: the quantity limit itself, and whether you are on private property or out in public where use is heavily restricted even if your quantity is legal.
Flower: Dried Cannabis Bud Limits At Home
Under California possession law limits weed in dried flower form to 28.5 grams for recreational users. This is roughly one ounce of cannabis buds. A few key points for flower at home:
- The 28.5 grams limit applies to what you are actively possessing, not what is still attached to your legal plants.
- Any harvested flower beyond 28.5 grams should be stored securely at home and not carried in public.
- Keep flower in child-resistant, labeled containers in a cool, dark place to protect potency and smell.
California marijuana possession 2026 is expected to remain anchored to these Prop 64 possession limits explained here unless state law changes. Always check current rules at cannabis.ca.gov for the latest updates.
Concentrates: Oils, Dabs And Vapes
Concentrated cannabis products are treated differently under California possession law limits weed because of their higher THC content. Adults 21 and over can possess:
- Up to 8 grams of concentrate, total
This includes:
- Vape cartridges and pods
- Dab products like wax, shatter, badder, rosin
- Syringes or jars of distillate or RSO
The 8 grams covers the net weight of THC concentrate, not the entire hardware. That means the oil inside a vape cart counts, not the metal and glass. Exceeding 8 grams of concentrate can push you into misdemeanor territory, which we cover below.
Edibles And Infused Products: How They Fit Into The Limits
Edibles can create confusion because you normally buy them in milligrams of THC, not grams of cannabis. California law counts the concentrate within infused products toward your 8 gram concentrate limit.
Here is how to think about edible and infused product storage under legal weed storage California rules:
- Look at the package for total THC per package, not per serving.
- All of the THC in those products still has to fit within the legal concentrate limit.
- Infused beverages, tinctures, capsules, and topicals are handled the same way.
Practically, state law focuses more on possession by weight of concentrate than on the exact THC milligrams in each edible package, but you should assume all infused products count toward your 8 gram concentrate cap.
Plants: Growing Up To Six At Home
For adults 21 and older, cannabis quantity allowed California home for cultivation is:
- Up to 6 living plants per private residence, total, not per person
Key rules for home grows under Prop 64:
- Plants must be in a locked area.
- Plants and harvested cannabis cannot be visible from a public place.
- Local governments can require grows to be indoors or add permits.
The flower on your plants does not count toward the 28.5 grams limit until it is harvested and processed. Once harvested and stored, you need to keep personal-use quantities within the legal possession limits.

What Happens If You Exceed The Legal Limit?
Going over California cannabis possession limits at home can move you from legal personal use into infraction or misdemeanor territory, depending on the situation.
For adults 21 and over:
- Possessing more than 28.5 grams of flower is a misdemeanor.
- Possessing more than 8 grams of concentrate is a misdemeanor.
- Growing more than 6 plants is usually a misdemeanor.
Typical misdemeanor penalties can include:
- Up to 6 months in county jail
- Fines up to 500 dollars
If you are under 21, possession is usually handled as an infraction with community service and drug education, not jail, but it still creates a record. Larger quantities, signs of sales, or involvement of minors can trigger more serious charges.
Renters, HOAs And Landlords: Can They Stop You?
State law allows adult use of cannabis, but property owners still have a lot of control. Even though cannabis quantity allowed California home is defined by state law, renters and people in HOA communities face extra rules.
Landlords can:
- Ban smoking or vaping on the property, including cannabis.
- Ban all cannabis use and cultivation in a lease agreement.
- Restrict growing plants indoors due to mold, electrical, or odor concerns.
HOAs can:
- Prohibit outdoor cultivation, even within the six plant limit.
- Limit smoking on balconies, patios, and common areas.
You may still be able to quietly store legal amounts of cannabis in your unit if the lease only bans smoking, but if the contract clearly prohibits possession or cultivation, violating it can lead to eviction even though the conduct is legal under state law.
Frequently Asked Questions
How much weed can you have in California at home if it is all edibles?
Edibles count toward your 8 gram concentrate limit, since the THC inside them is concentrated cannabis. There is no separate “edibles only” limit, so flower plus the concentrate in edibles together must stay within the legal caps.
Can medical patients possess more than the standard limits?
Yes. Qualified medical cannabis patients often have higher possession and cultivation limits based on their physician’s recommendation. Those rules are different from adult-use Prop 64 limits and are handled under California’s medical cannabis program.
Do these limits change outside my house, like at a friend’s place?
No. The same statewide possession limits follow you from home to home and in public. What changes is how strictly use is restricted. You still cannot smoke in public or carry an open container in a vehicle, even if you are under the gram limits.
Conclusion: Knowing the California cannabis possession limits at home helps you store your flower, concentrates, edibles, and plants confidently without drifting into illegal territory. Always check local city or county rules, which can be stricter than state law, and confirm current regulations with the California Department of Cannabis Control at cannabis.ca.gov before you stock up or start a home grow.
