Before a cremation chamber can operate, most facilities need an air permit from their state, local zoning approval, standard building and mechanical permits, and, in many states, a crematory license and a certified operator. Permitting is the most common cause of delay between signing a quote and performing the first cremation. Cremation Systems builds equipment designed for modern emissions requirements and provides hands-on help with the permitting process, including an in-house air permit specialist.
Why Permitting Is the Biggest Obstacle in a Crematory Project
Equipment is manufactured in about three months, and most buildings can be adapted in a similar time. Permits do not always keep pace. Some states process air permits in weeks; others take months. A zoning hearing can add more time if a crematory is not an explicitly permitted use at your site. Starting the permit process the day you commit to the project, and knowing which approvals you need, is the single best way to keep a crematory on schedule.
What Approvals Does a Crematory Need?
Requirements vary by state and municipality, but most projects involve some combination of the following.
| Approval | Issued by | What it covers |
|---|---|---|
| Air permit | State air quality agency | Authorization to construct and operate equipment that emits to the air. Most states require one; a few do not. |
| Zoning approval | Local planning or zoning board | Confirms a crematory is an allowed use at the site, or grants a variance after a hearing. |
| Building permit | Local building department | Structural work, new construction, or modifications to an existing building. |
| Mechanical and fuel/gas permits | Local building or fire authority | Gas piping, venting, stack installation, and related mechanical work. |
| Certificate of occupancy | Local building department | Final sign-off that the finished space is approved for its intended use. |
| Crematory establishment license | State funeral service board | Required in many states for human crematory operations. |
| Certified crematory operator | State board, training via CANA or similar | About half of U.S. states require certified operators for human cremation. |
Not every project needs every item. Pet crematories, for example, often face fewer state licensing requirements than human crematories. Your local and state agencies have the final word, and Cremation Systems can help you identify what applies to your site.
Air Permits and Emissions
Most states require an air permit to construct and operate a crematory because the equipment emits to the atmosphere. Air permits are issued by the state air quality agency, not the EPA directly, though state programs operate under federal Clean Air Act authority.
What do state air permits typically address?
Air permit applications generally ask for the equipment make and model, fuel type, operating capacity, stack height and location, and documentation of how the equipment controls emissions. Common areas of regulatory focus include:
- Opacity. How visible the stack emissions are. Modern cremation equipment is designed to operate with little or no visible emissions during normal cycles.
- Particulate matter. Fine solids carried in the exhaust stream.
- Secondary chamber (afterburner) operation. Exhaust from the primary chamber passes through a secondary chamber where it is held at high temperature to complete combustion before leaving the stack. State permits commonly specify operating conditions for the secondary chamber.
- Recordkeeping. Many permits require logs of operating temperatures, cycle times, and maintenance.
How does Cremation Systems equipment address emissions?
Cremation Systems chambers include a secondary combustion chamber and an opacity sensor that monitors stack emissions throughout the cycle. Fire Marshal and Tek Marshal provide monitoring, alarms, and data logging, enabling operators to document each cycle and simplifying the recordkeeping and annual reporting that permits typically require.
Does every state require an air permit?
No. Most do, but a few states do not require an air permit for cremation equipment, and some offer streamlined applications for human or pet chambers. Processing times also vary widely, from a few weeks to many months. Your state air quality agency sets the requirements, and Cremation Systems can help you determine which ones apply.
Local Permits and Zoning
Local approvals run on a separate track from the state air permit and are often the first step.
- Zoning. Confirm in writing with your planning and zoning department that a crematory is an allowed use at your site. If it is not, you will need a variance or special use permit, which usually requires a public hearing.
- Building permit. Required for new construction or structural changes to an existing building, including openings for the stack.
- Mechanical and gas permits. Cover gas piping, venting, and stack installation. Some jurisdictions involve the fire marshal in this review.
- Certificate of occupancy. Final inspection confirming the space is approved for use as a crematory.
Zoning hearings are where community concerns about smoke, odor, and property values come up. Our Zoning Hearing Preparation guide covers how to present factual information on modern cremation practices and emissions standards, as well as how to prepare for the questions boards typically ask.
Certifications and Listings
Cremation Systems chambers are UL listed. A UL listing means the equipment has been evaluated by Underwriters Laboratories against applicable safety standards. Local building and fire officials frequently ask for listed equipment, and a UL listing can simplify mechanical and fire inspections.
A UL listing addresses equipment safety. It is separate from your air permit, which addresses emissions, and from zoning and building approvals. All are typically needed.
Pet vs. Human Cremation: Regulatory Differences
Air permits and local building approvals apply to both pet and human crematories because the equipment and emissions are similar. The differences are mainly in licensing and operator requirements.
- Human cremation is regulated by the state funeral service board in most states. Many require a crematory establishment license, and about half require a certified crematory operator. Documentation of each cremation is typically mandatory.
- Pet cremation falls outside funeral board jurisdiction. Fewer states require licensing or operator certification, though air permits, zoning, and building permits still apply. Some states offer a simpler air permit path for pet chambers.
Facilities that run both human and pet equipment should expect to meet the human cremation requirements for the facility as a whole.
How Long Does Permitting Take?
There is no single answer, but a realistic plan accounts for these stages, several of which can run at the same time:
- Zoning confirmation or hearing. A written confirmation can take days. A variance hearing can take one to several months depending on meeting schedules.
- Air permit application. Prepared once equipment is specified. State processing ranges from about a month to many months.
- Building, mechanical, and gas permits. Typically issued on a local schedule once plans are submitted.
- Equipment manufacturing and site work. About three months each, usually running in parallel with permit review.
- Installation, inspection, and occupancy. Final inspections and certificate of occupancy after installation.
- Crematory license and operator certification (human cremation). Applied for as the facility nears completion.
The projects that stay on schedule are the ones that start the permit conversation at the quote stage rather than after the deposit.

Frequently Asked Questions
Do I need an EPA permit to operate a crematory?
In most cases, the permit comes from your state air quality agency rather than the EPA directly. State programs operate under federal Clean Air Act authority, so federal requirements are built into the state permit. Most states require an air permit for cremation equipment; a few do not.
What zoning designation is required to add a crematory to my facility?
Zoning requirements vary by municipality and depend on the property’s location, existing zoning classification, and proposed use. Contact your local zoning department to confirm whether a crematory is permitted at your location.
Does a crematory produce smoke or odor?
Modern cremation equipment with a secondary combustion chamber is designed to operate with little or no visible emissions or odor during normal cycles. Opacity monitoring tracks stack emissions throughout operation. Neighbors of properly operated crematories often report being unaware one is nearby.
What is a secondary chamber or afterburner, and why does it matter for permits?
The secondary chamber holds exhaust gases from the primary chamber at high temperature to complete combustion before they leave the stack. It is the primary emissions control on cremation equipment, and state air permits commonly set operating conditions for it.
Are there minimum stack height requirements?
Yes. A commonly applied building code requirement is that a stack extend at least 3 feet above the roof penetration and at least 2 feet higher than any structure within 10 feet.
Is Cremation Systems equipment UL listed?
Yes. Cremation Systems chambers are UL listed, which means they have been evaluated against applicable safety standards. Local building and fire officials often ask for listed equipment.
Are pet crematories regulated the same way as human crematories?
Air permits and local building approvals apply to both. Human crematories are additionally regulated by state funeral service boards, which often require a crematory license and certified operators. Pet crematories generally face fewer licensing requirements, though this varies by state.
Do I need a certified crematory operator?
About half of U.S. states require a certified operator for human cremation. Training is available through CANA and other accredited organizations, online or in person. Some states, such as New York, require in-person training. Check with your state funeral service board.
Can I install a second cremation chamber without applying for another permit?
In many cases, adding a second cremation chamber requires a modification to your existing air permit or approval of a new permit.
How long does it take to get an air permit?
It depends on the state. Some process applications in about a month; others take several months or longer. Start the application as soon as your equipment is specified.
What if my property is not zoned for a crematory?
You will likely need a variance or special use permit, which usually requires a public hearing before the planning or zoning board. Our Zoning Hearing Preparation guide explains how to prepare.
What documents should be available during a crematory inspection?
Whether you are scheduled for a routine inspection or just want to be prepared, keep these items accessible: the retort owner’s and operation manual, a copy of your permit to operate or air permit, operator training certificates, operational logs, emissions reports, and preventative maintenance records.
Do I need to notify the state if ownership of my crematory changes?
Yes. A change in ownership may require notification to the applicable regulatory agencies and updates to your permits, licenses, or establishment registration. Contact the appropriate agencies before finalizing an ownership transfer to determine what notifications, applications, or approvals are required.
Will Cremation Systems help me get my permits?
Yes. We help identify your requirements, provide the technical documentation agencies need, and assist with air permit applications. Our in-house Air Permit Specialist works directly with customers through the process.
