TL;DR
Renewal in California is not a USDA license card. You keep the CDFA custom livestock slaughterhouse license current and you stay inside 21 U.S.C. 623 and 9 CFR 303.1. Meat is household use only, marked Not for Sale. Confirm the current state fee and cycle with CDFA MPES. FSIS still reviews custom-exempt plants. Nobody can honestly quote one statewide clock time.
What does custom exempt slaughter renewal in California actually mean?
It means you keep a California custom livestock slaughterhouse license current and you stay inside the federal custom exemption. It does not mean USDA hands you a renewed Grant of Inspection. Custom exempt operators in California are not in daily carcass inspection.
Federal law is the floor. 21 U.S.C. 623 keeps true custom work outside the chapter's daily inspection duty when the meat stays with the owner, the household, and nonpaying guests and employees [2]. 9 CFR 303.1 is the rule FSIS actually reads on the floor [1]. California then adds its own license shop, CDFA's Meat, Poultry and Egg Safety Branch, under the California Meat and Poultry Inspection Act [5].
Renewal is a file, not a ceremony. You pay whatever the current state license cycle requires (confirm that number with MPES, because I will not invent it). You keep the same marks, the same owner logs, and the same sanitary story you used last year. If the floor plan, water, or inedible handling changed, treat it like a new look, not a rubber stamp.
People mix this up with a USDA plant. A Grant of Inspection is a different application under 9 CFR 304.1 [9]. Official plants show up in the FSIS inspection directory [11]. Custom exempt is the other door. Walk through the right one or you will rebuild the room later.
Do you need a license for custom exempt slaughter in California?
Yes if you run a custom slaughter service in California. The federal exemption is not a free pass to open a kill floor. You still need the state license class CDFA uses for a custom livestock slaughterhouse, and you still have to stay inside 9 CFR 303.1 [1]. Killing your own animal for your own freezer is a narrower fact pattern. Advertising a service is not that pattern.
9 CFR 302.1 says inspection is required for operations in commerce except where Part 303 exempts them [10]. The custom text is narrow. 9 CFR 303.1 covers custom slaughter of cattle, sheep, swine, or goats delivered by the owner, with the meat used only in that owner's household [1]. 21 U.S.C. 623 says the same thing in statute form [2].
California still licenses the plant. The short title of that state scheme is the California Meat and Poultry Inspection Act, Food and Agricultural Code section 18650 [5]. MPES is the branch that names the license, sets the current fee, and tells you the current renewal cycle. Get that in writing from them. Do not trust a blog fee table.
If you want to sell meat, stop. That is a state-inspected or USDA-inspected path, not custom. Custom meat cannot be sold. Neighbors with cash are still buyers.
| Path | Daily carcass inspection | Can that meat be sold | Paper you keep current |
|---|---|---|---|
| Custom exempt | No | No | CDFA custom livestock slaughterhouse license, FSIS custom-exempt review file, Not for Sale marks, owner logs |
| California state inspected | Yes, CDFA | Yes, inside California | State grant of inspection |
| USDA inspected | Yes, FSIS | Yes, including interstate | FSIS Grant of Inspection under 9 CFR 304.1 |
I would call MPES before I called a contractor. Zoning and the regional water board come next. FSIS district staff come in once you know you are actually custom, not pretending.
What paperwork gets renewed, and what only gets reviewed?
The California license is the piece that actually renews. FSIS does not mail you a custom-exempt card with a new date. FSIS reviews the operation against the exemption and against sanitation, marks, and records [4]. Those are different verbs. Mix them up and you will wait on the wrong desk.
State side, you send whatever MPES is using this cycle. Application, fee, maybe a layout update, maybe nothing but the form if the room did not change. Confirm the packet. I am not going to invent a form number that MPES can retire next quarter.
Federal side, custom-prepared carcasses must be marked “Not for Sale” in letters at least three-eighths inch in height under 9 CFR 316.16 [3]. That mark is not optional artwork. It is the whole point of the exemption. Keep the stencil. Keep a photo in the file.
Owner logs stay live all year. Who delivered the animal, what species, what date, where the meat went. If you cannot name the owner, you are not custom. You are an uninspected vendor, and that is a bad day.
Drawings, water tests, inedible contracts, and pest logs do not expire on a pretty calendar. They go stale when the facts change. A new rail, a new septic story, a new cut room. That is a review trigger, not a renewal checkbox.
How much does custom exempt slaughter cost in California?
There is no official California custom kill price, and I will not invent one. Plants set their own tickets. The license fee is a CDFA number that moves. Confirm the current license fee with MPES. Confirm the current customer quote with two plants, in writing, split into kill, cut and wrap, and disposal.
The federal exemption does not charge a USDA custom license fee, because it is not a Grant of Inspection [9]. You are paying California to license the house, the county to leave you alone on zoning and wastewater, and your own crew to keep the floor clean enough that a review does not shut you down [4].
Build-out is the real money. A tight mobile unit can stay smaller. A stick-built room with bad drains will eat the year. I would spend on the floor, the hot water, and a boring inedible barrel program before I spent on a website or a vacuum packer. The packer does not get you legal.
Paying a consultant to certify you “USDA custom exempt” as if it were a plaque is a waste. 21 U.S.C. 623 is a statute, not a sticker [2]. Paying someone to fill the CDFA form can be worth it if you cannot read a license packet. Paying someone to promise a date is not.
If a seller quotes you a single statewide average for either the license or a steer, walk. Ask for the MPES fee schedule and a plant ticket instead.
How long does custom exempt slaughter take in California?
Killing and dressing one animal is hours. Aging is days if you chill it right. The license is a different clock, and nobody honest can quote one statewide processing time. Confirm timing with CDFA MPES and with your county. I will not invent a week count.
A renewal year with no layout change is shorter than year one. Year one includes planning, water, wastewater, and whoever owns your septic or sewer story. That stack is why people lose a season. The slaughter itself was never the long part.
FSIS custom-exempt review is scheduled on FSIS time, not yours [4]. Do not tell a livestock owner you are approved next month. You do not control that. You control whether the marks, the logs, and the floor are ready when someone walks in.
If you need a date for a business plan, put a range you can miss and still pay rent. Then call the board. A consultant who guarantees a calendar is selling comfort.
What does FSIS still check if you are custom exempt?
FSIS still checks that you qualify for the exemption and that the place is clean enough to stay in it. Directive 5930.1 is the custom exempt review process [4]. Daily inspectors are not standing at your rail. That is the point. It is not an invisibility cloak.
They look at the story you tell with paper. Owner names. Species. Dates. Destinations. They look at the carcass mark. 9 CFR 316.16 wants “Not for Sale” in letters at least three-eighths inch high [3]. They look at inedible control, pests, water, and whether product that looks like retail is sitting in a case.
21 U.S.C. 623 keeps custom slaughter out of daily federal carcass inspection only when the meat stays in the owner's household [2]. If your cooler has price tags, you handed them the case.
Sanitation is still your job. Custom plants are not official establishments under a Grant of Inspection, so you are not running the same HACCP file a USDA plant runs [9]. Do not buy a 200-page HACCP binder to impress a custom review. Buy soap, hot water, and a floor that drains.
I would walk my own plant with a camera the week before any review. Photos of marks, the condemned barrel, the hand sink, the cooler thermometer. Cheap. Effective.
Which California agencies sit on the same file?
CDFA MPES holds the slaughterhouse license. CDFA Livestock Identification holds cattle brand inspection under the cattle protection statutes, starting at Food and Agricultural Code section 21051 [6]. Your county holds zoning and, often, the septic or pretreatment conversation. The regional water board holds a discharge if you have one. Cal/OSHA holds the workplace if you have employees.
That is a lot of doors. None of them care that your uncle in another state just kills on the farm.
MPES is the one people forget to call first, then remember after they pour concrete. Call them first. Ask what license class they will put on a custom livestock slaughterhouse this year. Ask whether a mobile unit is a different class. Write down the name of the person who answered.
Cattle add a second CDFA branch. Brand inspection is not meat inspection. It is ownership paper. Get the current trigger list from Livestock Identification before you book a slaughter day for someone else's steers [6].
County planning can kill a project that every food agency would have allowed. A kill floor in an ag zone is one conversation. A kill floor on a rural residential parcel is another. I would not order steel until planning says the use is real.
Wastewater is where quiet plants go to die. Blood and paunch contents are not household laundry. If you discharge, you need the permit that board actually issues. Confirm it. Do not guess from a forum.
What can you not do with custom slaughtered meat in California?
You cannot sell it. Not to a neighbor, not at a farmers market, not as “shares,” not as a restaurant special. The federal text is household use, members of the household, and nonpaying guests and employees [1] [2]. Cash makes it a sale.
You cannot ship it as inspected product. You cannot slap a mark of inspection on it. You cannot mix it in a retail case with USDA boxes and hope nobody reads the stencil [3].
You cannot use custom product as the inventory for a meat CSA, a burger pop-up, or a wholesale account. If you want those channels, you need inspected slaughter, state or federal [9] [11]. Custom exempt work in California is a service to an owner. It is not a meat company.
Donating it to a food bank is still a transfer you should not invent a blessing for. Ask the receiving charity and MPES before you move a box. I would not.
Feeding employees is in the statute if they are nonpaying guests or employees in the household sense the Act uses [2]. Turning employees into a side market is not. Keep it boring.
Do cattle still need brand inspection before custom slaughter?
Often yes, because cattle protection paper is not waived just because the meat will be marked Not for Sale. Food and Agricultural Code section 21051 sits in the cattle inspection article [6]. The exact trigger list and the current exemptions live with CDFA Livestock Identification. Confirm the current rule for your county and your class of movement before kill day.
Sheep, goats, and swine do not ride that same brand statute. They still need an owner name in your custom log [1]. If you cannot prove who walked the animal in, you do not have a custom record.
People treat brand inspection as optional folklore. It is not. It is a second CDFA branch. Your MPES license does not perform it for you.
I would put the brand inspection slip in the same jacket as the owner card. One animal, one packet. When a review happens, you are not digging through a glove box.
What is different in year one versus a renewal year?
Year one is permission to exist. Renewal is proof you did not wander off the exemption. Year one is drawings, water, inedible, zoning, and the first FSIS look [4]. Renewal is the state license cycle plus the same marks and logs, unless you changed the room.
If you add a cut room, a smokehouse, or a second species you never disclosed, you are not in a quiet renewal. You are in a new review. Say that out loud before you order equipment.
Poultry is not a free add-on. Birds live under 21 U.S.C. 464 and 9 CFR 381.10, not under the red-meat custom sentence in 303.1 [7] [8]. A chicken day on a beef license is how files get ugly.
I would keep year-one photos. Empty room, drain test, first marked carcass. Renewal goes faster when you can show the room is the same room.
What would I actually put in the renewal file?
A thin binder beats a pretty one. Current CDFA license application and proof you paid whatever fee MPES is charging this cycle. A one-page layout that still matches the floor. Water test if anyone asked for one last time. Inedible pickup receipts. Pest logs that look like a human wrote them on the days you actually worked.
Owner log for every head. Name, address, phone, species, date in, date out. A photo of the Not for Sale mark on a carcass, with a ruler in the frame so the three-eighths inch letters in 9 CFR 316.16 are not a debate [3]. Cattle brand slips in the same sleeve [6].
A short SOP for the rail, the cooler, and the barrel. One or two pages. Not a novel.
If you want a prebuilt federal paper kit, CustomExemptPath sells a $249 one-time USDA Custom-Exempt Kit at /start. It does not replace the California license forms and it does not talk to MPES for you.
I would not buy software in year one. A spreadsheet and a folder work. Software is how people delay the sink.
How do custom exempt reviews usually go wrong?
Sales. That is the boring answer. A freezer with prices. A Facebook post. A restaurant ticket. 9 CFR 303.1 and 21 U.S.C. 623 do not have a friendly exception for “just this once” [1] [2].
The second failure is a missing owner. If the animal arrived with a first name and a wave, you do not have custom records. The third is a mark you can barely read. 9 CFR 316.16 wants letters at least three-eighths inch high [3]. A faint crayon does not get you there.
Dirty coolers and a drain that holds blood will end the visit. Custom exempt is still food. Directive 5930.1 exists because FSIS still walks these rooms [4].
Scope creep is the slow failure. You start custom. You add a few inspected boxes for friends. You start grinding beef you bought in and beef you custom-killed in the same tub. Now nobody can tell the story. I would run two rooms or I would not run the second business.
Promising dates you do not control is how you create angry owners and sloppy shortcuts. Skip the promise.
How does California compare to nearby states?
The federal floor is the same in every state. 21 U.S.C. 623 and 9 CFR 303.1 do not change at the Colorado River [1] [2]. The state license shop does. California uses CDFA MPES and still runs a real state inspection program if you later want to sell inside the state [5]. That second path matters. Some states barely have it.
If you are comparing paper, read the neighbor guides the same way you read this one. Arizona's renewal path is the closest desert stack. Colorado custom exempt renewal and Idaho custom exempt renewal are the inland versions. Hawaii custom exempt renewal is the island version of the same federal sentences. Alaska custom exempt renewal is useful if you think distance changes 303.1. It does not. Florida custom exempt renewal is a large-state contrast on timing and counties.
I would not move a plant to dodge California paper. I would pick the path (custom, state inspected, USDA) before I picked a county. The wrong path in a cheap building is still the wrong path.
CustomExemptPath is an independent publisher, not a law firm and not MPES. If you want the federal kit after you have the state class name in writing, it is $249 one time at /start. The useful work is still the phone call to the Branch.
Frequently asked questions
Do you need a license for custom exempt slaughter in California?
Yes if you offer custom slaughter as a service. The federal exemption in 21 U.S.C. 623 and 9 CFR 303.1 is not a California operating license. CDFA's Meat, Poultry and Egg Safety Branch licenses custom livestock slaughterhouses. Killing your own animal for your own household is a narrower fact pattern. Confirm the current class name with MPES before you advertise.
How much does custom exempt slaughter cost in California?
There is no official statewide price. Confirm the current CDFA license fee with MPES. Confirm kill and cut-and-wrap tickets with two plants, in writing. Build-out and wastewater dwarf the license line. Anyone quoting one standard California custom fee from memory is guessing. I would not pay for a promised approval date.
How long does custom exempt slaughter take in California?
One animal is hours on the rail and days in the cooler if you age it. The license and reviews are a separate clock. Confirm timing with CDFA MPES, your county, and FSIS. A quiet renewal is shorter than a first plant. Nobody can honestly publish one statewide processing time, and I will not invent one.
Can I sell custom slaughtered meat to neighbors in California?
No. 9 CFR 303.1 and 21 U.S.C. 623 limit that meat to the owner, the household, and nonpaying guests and employees. A neighbor with cash is a buyer. Not for Sale on the carcass is the rule, not a suggestion. If you want to sell, you need state or federal inspection, not a custom story.
Is a USDA Grant of Inspection the same as custom exempt?
No. A Grant of Inspection is the official plant path under 9 CFR 304.1. Those plants appear in the FSIS inspection directory and can sell meat, including interstate if they stay in compliance. Custom exempt is an exemption from that daily inspection. Different application. Different cooler rules. Different business.
Do I need HACCP for a custom exempt plant in California?
Not the official 9 CFR 417 HACCP file a USDA plant runs under a Grant of Inspection. You still need a clean room, sound water, inedible control, and records that prove the exemption. Buying a huge HACCP binder to impress a custom review is usually a waste. Spend on the sink and the drain.
Can I custom slaughter my own animals on my farm without a plant license?
Own-use slaughter for your own household sits on a different federal sentence than a public custom service. The moment you take in other people's animals, you are in the custom operator fact pattern and California expects the slaughterhouse license. Confirm local disposal, water, and county rules even for own-use. Do not advertise a service from a farm kitchen.
Does custom exempt cover poultry in California?
Not under the red-meat custom sentence. Poultry exemptions live in 21 U.S.C. 464 and 9 CFR 381.10. CDFA still has a say if you operate a plant. Do not add a chicken day to a beef custom file and assume the paper follows. Ask MPES and FSIS which class they want before the first bird.
What does the Not for Sale mark have to look like?
9 CFR 316.16 requires custom-prepared carcasses and parts to be marked Not for Sale in letters at least three-eighths inch in height at the time of preparation. Use a real stencil. Keep a photo with a ruler. A faint hand scrawl is how reviews go sideways. Packaged product has matching labeling duties. Keep it readable.
Who do I call in California to renew?
CDFA's Meat, Poultry and Egg Safety Branch for the slaughterhouse license. CDFA Livestock Identification for cattle brand inspection questions. Your county planning and environmental health offices for land and septic. FSIS for the custom-exempt review, not for a state fee. Confirm names and current forms on those desks. I will not invent a phone tree.
What if I also want to sell inspected meat later?
Plan the inspected path now. California state inspection can support in-state sales. A USDA Grant of Inspection supports interstate sales. Custom coolers and inspected coolers should not become one tub of trim. Many people waste a year building a custom-only room they later tear apart. Ask MPES what an upgrade actually requires before you pour.
Do I need a wastewater permit for custom slaughter?
If you discharge process wastewater, you need whatever permit the regional water board and the county actually issue for that discharge. Blood and paunch contents are not household laundry. A drum-and-haul story is still a story you must be able to prove. Confirm it before you design the floor. Guessing here is how plants sit idle.
Can a mobile custom slaughter unit renew the same way?
It renews through the same California branch, but the license class may differ from a stick-built house. Confirm that class and the current fee with MPES. FSIS still cares about the exemption, the marks, and sanitation. Counties still care where you park and where blood goes. Do not assume a truck skips the file.
