TL;DR
California legalized natural organic reduction (NOR) through AB 351, effective January 1, 2027. The Cemetery and Funeral Bureau will license NOR facilities. No applications are open yet. The likely fee tracks the $1,200 funeral establishment license, and the composting process itself runs 30 to 45 days.
When does human composting become legal in California?
January 1, 2027. That date is written into Assembly Bill 351, which Governor Gavin Newsom signed on September 18, 2022 [1]. The bill added Chapter 13 (commencing with Section 9260) to Part 1 of Division 7 of the Health and Safety Code. It defines natural organic reduction as the "contained, accelerated conversion of human remains to soil" and makes it a lawful method of final disposition [1].
Before 2027, no facility can legally perform NOR in California. The law gives the Cemetery and Funeral Bureau (CFB) until that date to draft and adopt the regulations that govern the whole practice. If you are reading this before 2027, you are in the prep phase. No shortcuts.
Do you need a license for human composting in California?
Yes. Once the law takes effect, any facility that performs natural organic reduction must hold a license from the Cemetery and Funeral Bureau. The statute states that the bureau "shall adopt regulations to implement this chapter," and licensing is part of that [1]. You cannot operate under a plain funeral establishment license. You will need a specific NOR license, or the bureau may fold NOR into a new dispositioner category. The exact name is not set.
This is a state license, not a local permit. It comes from the CFB. Your county health department may add its own rules for solid waste or public health, but the primary operating authority is the bureau. If you plan to offer NOR next to traditional funeral services, expect to hold both a funeral establishment license and a NOR license.
Here is what similar licenses cost in states that already legalized NOR, so you can see the fee landscape:
| State | License type | Application fee | Renewal fee |
|---|---|---|---|
| California | Funeral Establishment (CFB) | $1,200 | $1,200 |
| Colorado | Funeral Establishment (DORA) | $340 | $340 |
| Washington | Funeral Establishment (DOL) | $1,410 | $1,410 |
Source: [2], [5], [6]. The California NOR license fee has not been published. It will probably land in this range. The CFB fee schedule is the best reference until the new regulations arrive.
Who regulates human composting in California?
The Cemetery and Funeral Bureau, part of the California Department of Consumer Affairs, has jurisdiction over all death care licensing in the state. It already regulates cemeteries, crematories, funeral establishments, and embalmers. AB 351 puts natural organic reduction directly under that authority [1].
The bureau has not issued any NOR-specific rulemaking notices yet. The statute requires the bureau to adopt regulations by January 1, 2027, but the real timeline can slip. The bureau will hold public hearings and take comments before finalizing the rules. If you want to shape the requirements, that comment window is where you do it.
What will the license application look like?
Nobody knows the exact form yet. But the existing funeral establishment application maps the likely structure. A new funeral establishment license in California requires an application form, a fee, a criminal background check, and a physical inspection of the premises [2]. The CFB also wants proof of compliance with local zoning and health codes.
Expect the NOR application to mirror that. You will probably submit a facility plan, a description of the reduction vessels and process, a waste management plan, and evidence of operator training. The bureau may require that a licensed funeral director or a NOR operator hold a separate individual license. The HumusPath NOR Facilitator Statute Kit breaks the legislative text into checklists, but the bureau's final regulations are the only binding document.
Plan for a six-month review cycle. The bureau does not move fast. File on day one and you might get your license by mid-2027. Nobody knows the exact timeline, and the bureau's workload will be heavy that first year.
How much does the license cost?
The NOR license fee has not been set. The CFB's current fee for a funeral establishment license is $1,200 for the initial application and $1,200 for each annual renewal [2]. That is the closest proxy. The bureau might set the NOR fee at the same level, or it might build a new fee tier. No one can promise a number.
On top of the state fee, you prepare your facility for a physical inspection. The CFB does not charge a separate inspection fee, but you carry the cost of getting your site ready for a compliance visit. You will also pay local business license fees, zoning permits, and possibly a solid waste permit if your facility processes more than human remains. First-year licensing, application fee plus local permits, could realistically run between $2,000 and $5,000. That is an estimate from comparable businesses. The final number depends on your county.
How long does human composting take?
The natural organic reduction process runs about 30 to 45 days. That is the window you quote families. The WSU pilot study that helped validate NOR in Washington found the active decomposition phase in a controlled vessel takes roughly 30 days, followed by a curing period of a few more weeks [3]. The soil is then tested for safety and returned to the family.
California has not set a statutory minimum or maximum processing time. The bureau's regulations may add a required holding period, but the biology is identical across state lines. Build your operational model around a 45-day cycle from intake to soil release. That gives you margin for testing, paperwork, and the family delays that always happen.
How much does human composting cost for consumers?
No law caps the price a family pays for natural organic reduction in California. In other states, providers charge between $5,500 and $7,000 for the full service, which covers the reduction process, the soil return, and basic administrative support [4]. That range comes from a Los Angeles Times report on early NOR providers in Washington and Colorado.
Your pricing depends on your overhead, your facility's capacity, and the local market. Cremation in California averages around $1,000 to $2,000, but NOR is a new category with a different offer. The soil is a real product a family carries home. Some providers add options like a tree planting or an urn for the soil. Price the service to cover license costs, vessel maintenance, operator labor, and the 30-day hold. None of those costs are small.
What are the facility requirements for human composting in California?
The law says little about the facility itself. It requires that natural organic reduction happen in a "reduction vessel" that is "contained" and "accelerated" [1]. The details come from the bureau's regulations. Expect requirements that vessels be stainless steel or a similar non-porous material, that they carry temperature and moisture controls, and that the facility keep a dedicated area for the reduction and curing stages.
You will also meet Americans with Disabilities Act (ADA) requirements for public access if families come on site. The local fire department will want a fire suppression plan. The county health department may require a waste management plan for any non-tissue materials that enter the vessel. You will likely need a separate area for storing finished soil, which must be tested for pathogens and heavy metals before release. The WSU study found the soil exceeded EPA safety standards for every tested contaminant [3]. That data will anchor your environmental compliance argument.
How to prepare now for a 2027 launch
You have time. Use it. Start by securing a location zoned for funeral services or light industrial use. Talk to your city planner about the use classification for natural organic reduction. The term is new, and you may have to explain it. Then build relationships with local funeral homes. They are your referral source. Most funeral directors have never heard of NOR, and they need to know you are a legitimate, licensed operator.
Next, vet vessel manufacturers. There are no California-approved vendors yet, but the bureau will likely require vessels to meet design standards. Ask manufacturers for documentation on temperature control, airflow, and containment. You need that for your application. Set aside a budget for the application fee, the facility inspection, and the first year of operating capital. The HumusPath NOR Facilitator Statute Kit helps you line-item the legal requirements so you do not miss a step.
What other states have legalized human composting?
California is the eighth state to legalize natural organic reduction. Washington led in 2019, followed by Colorado, Oregon, Vermont, New York, Nevada, and Arizona. Each state has its own framework. If you want a multi-state operation, the license requirements are not reciprocal. You need a separate license in each state. Our guides on human composting license in Colorado and human composting license in Utah walk through those. The California model is closest to Washington's, but the CFB is a different bureau with different inspection protocols. Do not copy-paste a Washington application.
Common mistakes to avoid
The biggest mistake is applying too early. The CFB will not accept a NOR license application before the regulations publish. File a form and it comes back. Wait for the bureau's announcement. The second mistake is ignoring the funeral establishment license. If you also offer traditional funeral services, you need both licenses. The CFB will not let you bundle them.
A third mistake is misreading the soil. This is not backyard compost. It is a heavy, nutrient-rich material that requires testing. The WSU study showed the soil is safe, and it also showed the process demands precise monitoring. You cannot buy a vessel and start. The bureau will require proof of operator training. Get that training now, even from a provider in another state.
Frequently asked questions
Do you need a license for human composting in California?
Yes. Once AB 351 takes effect on January 1, 2027, any facility performing natural organic reduction must hold a license from the Cemetery and Funeral Bureau. The specific license type has not been created yet, but it will be a state-level requirement, not a local permit.
How much does human composting cost in California?
The consumer price is expected to range from $5,500 to $7,000, based on pricing in other states [4]. The actual cost depends on the provider's overhead, the facility's capacity, and the local market. The operator's state license fee is not yet set, but the funeral establishment fee of $1,200 is a reasonable proxy.
How long does human composting take in California?
The natural organic reduction process takes about 30 to 45 days. The active phase in a controlled vessel lasts roughly 30 days, followed by a curing period. This timeline matches the WSU pilot study [3] and is not expected to change under California regulations.
Can I start a human composting business in California right now?
No. The law takes effect on January 1, 2027. You cannot legally operate a NOR facility before that date. You can prepare your location, secure zoning, and get training, but you cannot accept remains or charge for NOR services until you hold a license from the CFB.
What is the exact name of the license I need?
The bureau has not named the license yet. It may be a "natural organic reduction facility license" or something similar. The statute uses the term "natural organic reduction." The CFB will publish the official name when it releases the regulations.
Will I need a funeral director license to operate a human composting facility?
The law does not require a funeral director license for the facility itself, but the bureau may require an individual responsible for the reduction process to hold a separate operator license. The regulations will clarify this. If you also offer arrangement services with families, you may need a funeral director license.
How long does it take to get a license once I apply?
There is no official timeline. The CFB's review of a new funeral establishment application can take six months or more. The first NOR applications will likely take longer because the bureau will be learning the process. Plan for a full year from application to issuance.
Can I use a mobile human composting unit in California?
The statute does not address mobile units. The bureau's regulations will likely require the facility to be a fixed location. A mobile unit raises questions about zoning, waste disposal, and inspection. It is unlikely to be approved in the first round of regulations.
What testing is required for the finished soil?
The law does not spell out testing protocols, but the bureau will almost certainly require pathogen and heavy metal testing before the soil can be released. The WSU study tested for fecal coliform, salmonella, and heavy metals and found the soil met EPA safety standards [3]. That data will inform the regulations.
Is human composting legal in my county?
Once the state law takes effect, NOR is legal statewide. But counties can impose zoning restrictions or extra health permits. Check with your county planning department and health department before securing a location. The state license does not override local zoning.
How do I get trained as an NOR operator?
There is no California-specific training program yet. Several providers in Washington and Colorado offer operator training covering vessel operation, temperature control, and soil testing. The CFB may eventually approve a curriculum. Getting trained now in another state is a strong signal to the bureau that you are serious.
What happens to the soil if the family does not want it?
The law specifies the soil belongs to the family. If the family does not want to take possession, the provider must have a plan for its disposition. You can donate it to a conservation group or a land trust, but you cannot simply discard it. The bureau will likely require a written plan for unclaimed soil.
