The real cat converter desk board path in California

Last updated 2026-08-19

What is the cat converter desk board in California?

There isn't one. People search for a cat converter desk board because other states park metal buyers under a single occupational shop. California splits the same work across statutes, cities, and (if you take cars apart) the DMV.

The statewide text that names your trade is the junk dealer and recycler article in the Business and Professions Code, starting at section 21600. That article treats catalytic converters as junk with extra fields, not as a separate license class. ^[1] Local police and city finance desks then decide whether your address can buy from the public. The DMV joins only if you fit the automobile dismantler definition.

So the "board" is a stack. You confirm each layer with the office that prints the paper. Anyone selling a single statewide catalytic converter dealer number is selling a story.

I'd treat California as a records state first and a permit state second. The statute already tells you what to write down on each converter. The city tells you whether you may sit at that address and take property from walk-ins. Those are different questions. Mixing them up is how people lease a bay, buy a torch, and then learn the cop shop will not issue them.

Do you need a license for a cat converter desk in California?

Yes, in the practical sense. You need paper before you buy converters from other people. No, in the myth sense. California does not issue a standalone "cat converter desk" license with its own board and quota.

If you buy junk, including catalytic converters, you sit inside Business and Professions Code sections 21600 and following. That article defines a junk dealer as a person "engaged in the business of buying, selling, and dealing in junk." ^[1] Recyclers and core buyers get pulled into the same record and payment rules, including the catalytic converter section at 21610. ^[4]

On top of that statute you still need the ordinary local business license for the city or county where the desk sits. Many police departments also run a junk dealer or secondhand dealer permit. Secondhand dealers are a separate article beginning at Business and Professions Code 21625. ^[12] Some cities fold converter buys into that desk. Some do not. Ask the local permitting cop, not a forum.

If you wreck cars or strip them for parts, you also need a DMV automobile dismantler license. Vehicle Code section 11500 makes it unlawful to act as a dismantler without a department license or temporary permit. ^[5] A pure buying counter that never takes in whole vehicles may stay outside that chapter. A yard that does both does not.

If you sell anything taxable, including processed metal or cores you later invoice, you need a California seller's permit from the California Department of Tax and Fee Administration. The permit itself has no state application fee. ^[10]

I would not open the door to public sellers on a city business license alone. That license proves you pay local tax. It does not prove you may buy regulated property. Get the police or sheriff answer in writing before you advertise a price list.

How much does a cat converter desk cost in California?

Nobody can quote one honest all-in number for a cat converter desk in California. The published state pieces are small. The local and site pieces are not, and they move by city.

If you form a California LLC, the Secretary of State's Articles of Organization (Form LLC-1) lists a $70 filing fee. ^[9] The LLC then files a Statement of Information. That fee has long sat at $20, but confirm the current line before you write a check. Every year the Franchise Tax Board collects an $800 LLC tax. Revenue and Taxation Code section 23153 states, "The applicable amount is eight hundred dollars ($800)." ^[8] Section 17941 applies that tax to LLCs doing business in the state. ^[8]

A CDTFA seller's permit costs $0 to obtain. ^[10] City business licenses, police junk permits, zoning clearances, and fire inspections are local. I will not invent those. I have watched people burn a month arguing with a broker about "state converter fees" while their city finance portal sat unopened.

The expensive line is usually the site, not the filing. A desk needs a legal place of business, a way to lock converters, and a scale you can defend. Insurance, cameras, and a fence are operating choices. They are not board fees. Confirm every government charge with the office that invoices it.

What I would not spend money on: a packaged "California catalytic converter license" sold as if it replaced the stack. That product does not exist. Pay the SOS. Pay FTB. Walk into city hall and the police permit window. Then price the lease.

Cost item	Published amount	Who sets it
LLC-1 articles	$70	California Secretary of State [9]
LLC annual tax	$800	Franchise Tax Board via RTC 23153 and 17941 [8]
Seller's permit	$0 to obtain	CDTFA [10]
City business or junk permit	Confirm locally	City or county
DMV dismantler license (only if you dismantle)	Confirm with DMV	DMV under Vehicle Code 11500 [5]

How long does a cat converter desk take in California?

There is no statewide clock, and anyone who quotes a guaranteed week count is guessing. Entity filings with the Secretary of State often come back in days to a few weeks, depending on the filing channel and the backlog that week. Confirm current processing on the SOS business entities pages before you promise a landlord a start date.

Local junk, secondhand, and zoning paper is the slow piece. A clean industrial address in a city that already licenses metal buyers can move in a few weeks. A storefront in a residential-adjacent zone, or a city that is tired of converter theft, can sit for months. Some cities want neighborhood notice. Some want the police to walk the cage and camera plan. I cannot honestly average that.

DMV dismantler licensing, if you need it, runs on occupational licensing time, not city-hall time. Budget for a site that already looks like a dismantler before you apply. Do not treat a pending DMV file as permission to pull cars apart. Vehicle Code 11500 requires the license or temporary permit first. ^[5]

A seller's permit from CDTFA is usually the fast state piece once the entity exists. ^[10] Still confirm. Systems go down. Names get rejected.

My working order is address first, local police and zoning second, tax accounts third, DMV last and only if the work is actually dismantling. Reversing that order burns calendar. It also burns deposit money on a bay you cannot legally use.

Which California agencies actually touch the desk?

Count the desks, not the mythic board. Statewide you will meet the Secretary of State for the entity, the Franchise Tax Board for the $800 LLC tax if you chose that form, and CDTFA for a seller's permit if you make taxable sales. ^{[8] [9] [10]}

The Business and Professions Code junk article is enforced locally. Peace officers use it when they walk a yard or hold a load. Section 21601 requires a written record of sales and purchases. ^[2] Section 21606 lists what that record has to hold. ^[3] Section 21610 is the catalytic converter add-on. ^[4] Section 21604 limits how some junk is paid for. ^[13]

If the city treats you as a secondhand dealer, the Department of Justice's secondhand reporting system enters the picture through Business and Professions Code 21625 and the sections after it. ^[12] That is a different article than the junk article. Some shops end up with both. Confirm with the local police permitting unit, because they are the ones who will reject your packet.

DMV occupational licensing appears only if you are an automobile dismantler. Their record rules live in Vehicle Code section 11520. ^[6] They care about vehicles and major component parts, not about your rhodium spot price.

CARB and the Bureau of Automotive Repair matter if you install converters on cars that will roll. A scrap desk that only buys cut-off converters is not an installer. Do not pay for a BAR shop license to run a buying counter. That is the wrong window.

What records does California make a recycler keep?

Written records. Dated. Tied to the seller. Kept so an officer can read them without a speech from you.

Business and Professions Code 21601 says every junk dealer and every recycler shall keep a written record of sales and purchases made in the course of the business. ^[2] Section 21606 fills in the fields: place and date, seller identity, description of the junk, and the vehicle or other facts the article names. ^[3] Section 21610 then special-cases catalytic converters. Read that section on LegInfo before you print a ticket. Do not run last decade's scrap ticket and hope. ^[4]

AB 1740 (Chapter 513, Statutes of 2022) is the bill most desks still mean when they say "the new converter law." It tightened who you may pay and what you must write. ^[7] SB 1087 from the same session also rewrote converter language in the junk article. ^[14] The current consolidated text is what you obey, not a tweet about the bill number.

If you want a field list that tracks the usual VIN, seller, and theft-compliance boxes, CatConPath sells a $179 one-time VIN-Log + Theft-Compliance Kit. It is a paper pack, not a license, and it does not talk to any board.

I keep photos. The statute talks about writings. A photo of the converter stamp, the seller's ID, and the load in the truck has settled more arguments than a prettier invoice template. Hold the file for as long as the article and your local permit both require. If those two numbers disagree, keep the longer one.

Payment method is part of the record. Section 21604 already restricts how certain junk is paid. ^[13] Converter buys picked up more limits in the 2022 bills. Confirm the current 21610 payment rule before you hand anyone cash. Cash is how desks get famous for the wrong reason.

Can you still buy converters from walk-in sellers?

Sometimes, and only if the seller and the paperwork fit the current text of section 21610 and your local permit. ^[4] The 2022 bills were written because street buys of loose converters were feeding theft. The legislature did not ban recycling. It narrowed the counter.

Read AB 1740 and the current 21610 together. ^{[7] [4]} Then ask your local police permit unit how they read "core recycler" and "junk dealer" at your address. A city that wants zero public converter traffic will say so in the permit conditions even if the statewide statute still allows a documented buy.

I would not buy a converter out of a backpack from a person who cannot tie it to a vehicle and to themselves. That was a bad idea before 2022. It is a worse idea now. Licensed dismantlers, repair shops with invoices, and owners with matching ID and vehicle paper are the boring path. Boring is the job.

If a seller is a licensed automobile dismantler, ask for the DMV license proof and keep a copy with the ticket. Vehicle Code 11500 is why that license exists. ^[5] If they cannot show it, they are not that seller.

Do you need a DMV dismantler license just to run a desk?

Not if the desk only buys already-removed converters and never takes in vehicles to strip. You still have the junk and local paper. You do not automatically become a dismantler by touching a converter.

You do need the DMV license if you act as an automobile dismantler. Section 11500 is the prohibition. ^[5] Section 11520 is the record chapter for that license. ^[6] "Acting as" is broader than the word on your door. If you buy whole cars, pull parts, and crush, you are in that chapter even if the money is in the cats.

A lot of people try to dodge DMV by calling the yard a recycling desk. That dodge fails the first time a patrol unit sees a row of shells and a forklift full of uncut cars. If the work is dismantling, budget for the dismantler packet and a site that already meets DMV's established place of business habits. Confirm the current application set with Occupational Licensing. I will not invent their fee line or their calendar.

If you are unsure which side of the line you are on, describe the actual workflow to DMV and to the city in writing. Keep their answers. Verbal shrugs are not a defense.

What about city junk permits, secondhand paper, and zoning?

This is where cat converter desk California plans usually die. The statewide junk article assumes you already have a lawful place to stand. Cities decide the place.

Zoning comes first. A buying desk with public traffic, a torch, and a cage is not a home occupation in most California zones. I would not sign a lease until planning and the police permit window both say the use fits. A cheap month-to-month on the wrong side of a residential line is not a bargain.

The police junk or secondhand permit is local even though the statutes are statewide. Secondhand dealers live in Business and Professions Code 21625 and following. ^[12] Junk dealers live in 21600 and following. ^[1] Your city may want one, the other, or a homemade hybrid. Bring the statute printouts. Still fill out their form, not yours.

Some cities will not license a new public-buy metals counter at all. That is a policy choice, not a paperwork error. If they say no, believe them. Moving two zip codes can change the answer. That is ugly, and it is real.

Fire and building can also hold the certificate of occupancy for cages, compressed gas, and exiting. None of that is romantic. All of it stops an opening day.

What federal rules still apply after California paper is done?

California paper does not wash federal tampering law. Clean Air Act section 203, codified at 42 U.S.C. 7522, makes it illegal for a person to remove or render inoperative an emissions device after sale to the ultimate purchaser, and it also hits people who sell or install defeat parts. ^[11]

A scrap desk buying a converter that is already off a wrecked car is not the same fact pattern as a shop cutting cats off running commuter cars. Intent and the rest of the vehicle matter. I am not your lawyer. I am saying the federal statute still exists after your city license prints. ^[11]

Do not advertise "we unbolt cats while you wait" on street-driven cars. That is how a buying counter becomes a tampering shop. Buy scrap that is already scrap. Leave running vehicles to licensed repair dealers who replace with legal parts.

Stolen property law is also still there. A tidy 21610 ticket does not launder a converter you had reason to know was stolen. If a hold order comes in, hold the part. Arguing about spot price during a hold is how people get a second visit.

What would I actually do first in California?

I would pick the city before the entity. Call planning. Call the police permit desk. Ask, straight, whether they will license a catalytic converter buying counter at a real address you can afford. Get names. Write the date.

If that answer is no, stop. Forming an LLC so you can lose $800 a year to FTB while you argue with zoning is a hobby, not a desk. ^[8]

If the answer is yes, lock a lawful site, then form the entity, then get the seller's permit, then finish the local junk or secondhand packet, then build the record habit around sections 21601, 21606, and 21610. ^{[2] [3] [4]} Only then decide if any part of the work is dismantling. If it is, add DMV. ^[5]

I would not buy a full lab XRF package on week one. A defendable scale, a camera that actually records, and a lockable cage matter more. Fancy assay gear does not impress a detective who wants seller ID.

I also would not hire a consultant who promises to "handle the board." There is no board. Pay a local land-use person if the zone is messy. Pay a California lawyer if your fact pattern is weird. Skip the national license mill.

How does California stack up against other states?

Stricter on public buys, split across more desks, and louder about theft. That is the honest comparison. Other states still run a cleaner occupational license story. California runs a statute-plus-city story.

If you already work another state, do not photocopy that packet. Arizona's path is its own stack. Read cat converter desk board in Arizona before you assume a border yard can share one file. Colorado is not California either. cat converter desk board in Colorado is the better starting page for that paper.

Operators who bounce between coasts keep making the same mistake. They treat Florida or Georgia packets as templates. They are not. Skim cat converter desk board in Florida and cat converter desk board in Georgia only to see how different the issuing shop is.

Illinois and Idaho are useful contrasts if you want a Midwest or smaller-state read. cat converter desk board in Illinois and cat converter desk board in Idaho will not get you a California permit. They will stop you from importing a form that names the wrong agency.

Alabama is even farther from this map, but people still paste it. cat converter desk board in Alabama belongs in a comparison tab, not in your Oakland filing.

What gets desks shut down after they open?

Buying from people who cannot own the part. Paying in a way 21610 no longer allows. ^[4] Keeping a notebook that would fail 21606 on a slow Tuesday. ^[3] Taking in whole cars without a dismantler license. ^[5] Moving the desk to a second address the permit does not name.

Theft holds get ignored. That one is pride. An officer says hold, and the load is already on a pallet headed out. Do not do that.

The other failure is tax. People treat the seller's permit as optional because "it's scrap." CDTFA does not care about your nickname for the load. If you make taxable sales, you needed the permit. ^[10] FTB still wants the $800 if you are an LLC doing business here, even in a quiet year. ^[8]

I have no magic count of raids or a statewide close-rate. Nobody publishes a clean desk-failure table. The closest honest signal is the 2022 bill pile itself. The legislature wrote AB 1740 and SB 1087 because loose converter cash was a policing problem. ^{[7] [14]} Act like that history applies to you. It does.

CatConPath is an independent publisher, not a law firm and not a service company. If you want the VIN-Log kit as a starting checklist after you have talked to the real offices, it is at /start. It will not replace a city no.

Frequently asked questions

Do you need a license for cat converter desk in California?

You need a stack of paper, not one magic license. Plan on junk dealer and recycler duties under BPC 21600 and 21610, a local business license, often a police junk or secondhand permit, a CDTFA seller's permit if you sell, and a DMV dismantler license only if you take cars apart. Confirm each item with the issuer. There is no standalone statewide desk license.

How much does cat converter desk cost in California?

Published state pieces are modest: a $70 LLC-1 fee at the Secretary of State, an $800 annual LLC tax under RTC 23153 and 17941, and a $0 CDTFA seller's permit. City junk permits, zoning, rent, and DMV dismantler fees if you need them are local or occupational. Confirm those. Anyone quoting one statewide all-in price is inventing it.

How long does cat converter desk take in California?

There is no statewide approval clock. SOS entity filings often return in days to a few weeks, but confirm current times. Local zoning and police junk or secondhand permits range from weeks to many months by city. DMV dismantler licensing, if required, is its own queue. Do not promise a landlord a date until the city has actually spoken.

Is there a California catalytic converter dealer license number I can apply for?

No. California never created a single catalytic converter dealer class with its own number series. You apply for the ordinary entity, tax, local junk or secondhand, and (if needed) DMV dismantler papers. A vendor selling a standalone "CA cat license number" is not describing a real board product.

Can a tow yard sell me converters without extra paper?

Only if that yard is a lawful seller under current BPC 21610 and you still write the ticket the statute requires. A tow yard is not a free pass. Ask for their dismantler or other license proof, match it to the load, and keep copies. If they cannot document the part, do not buy it. Your local permit can be stricter than the statewide floor.

Does a seller's permit let me buy cats from the public?

No. A CDTFA seller's permit lets you collect and remit sales tax on taxable sales. It is not permission to buy regulated junk from walk-ins. Public buys sit under BPC 21600 and 21610 plus whatever junk or secondhand permit your city issues. Get the police answer before you post a buy price.

Do I need CARB or BAR approval to scrap converters?

Not to scrap already-removed converters as metal. CARB and BAR matter when someone installs a converter on a vehicle that will be driven in California. A buying desk that starts cutting cats off street-driven cars has left scrap and entered tampering and repair-shop territory. Stay on the scrap side or get the right shop licenses.

What if I only buy from licensed dismantlers?

That is the cleaner fact pattern, and I would start there. You still keep BPC 21601, 21606, and 21610 records, and you still need local permission to operate the site. Copy the seller's DMV dismantler proof into every file. Vehicle Code 11500 is why that proof matters. Exclusive dismantler suppliers do not erase city zoning.

Are cash purchases of catalytic converters legal in California?

Do not assume yes. BPC 21604 already limits payment methods on some junk, and section 21610 plus the 2022 bills tightened converter payments further. Read the current 21610 text on LegInfo and ask your local permit unit how they enforce it. Cash at the counter is the habit most likely to fail an inspection.

Does an LLC protect me if I buy a stolen converter?

No. An LLC can separate some business debts. It does not bless a bad buy. Stolen property rules still apply to the person who took the part and to the desk that had reason to know. Keep the statutory record, run holds when you are told to, and do not hide behind the SOS file number.

What records should I keep on each converter?

At minimum, the written fields in BPC 21601, 21606, and 21610: dates, seller identity, description, and the converter-specific items 21610 names. I also keep photos of stamps, ID, and the load. If you are a secondhand dealer locally, add that article's reporting. Hold files for the longest of the statute, the local permit, and your lawyer's advice.

Can I run a cat converter desk California operation from a residence?

Usually no. A public-buy metals counter with storage and cutting is a commercial or industrial use in most California zones. Home occupation rules almost never stretch that far. Confirm with city planning before you spend on a garage cage. A residential no is a no, not a paperwork delay.

Who do I call to confirm my local junk dealer rules?

Call the city or county business license desk and the police or sheriff unit that issues junk or secondhand permits. Ask for the application name, not a general crime-prevention line. Then read BPC 21600 and 21625 yourself on LegInfo so you can tell when a clerk is mixing the two articles. Get the answer in writing.
