Filing a DBA in L.A. County Costs $26. Publishing It Can Cost $575.

The county's fee is fixed. The newspaper notice the law requires starts at $29 and climbs to $575.

You're wondering whether this even applies to you. The test is in Business and Professions Code section 17900, and it is shorter than you'd expect. For an individual, a fictitious business name — a DBA, short for "doing business as" — is any name that doesn't include your surname, or any name that suggests owners who aren't there. The code names the words that do the suggesting: "Company," "& Company," "& Son," "& Sons," "& Associates" and "Brothers," while words that merely describe the business don't count. Say your surname is Ruiz: take work as Ana Ruiz and you owe the county nothing. Take it as Ruiz & Associates, or as Alder Studio, and you owe it a filing within 40 days of the day you started, under section 17910.

The county's share of that is cheap and fixed. What comes after it is neither, and it's the part almost nobody prices out first: state law makes you buy a legal notice in a newspaper, and the newspaper sets its own price. We pulled the county's own list of approved papers on September 3, 2026, counted 136 of them, and compared every fee printed beside a name. The cheapest is $29. The most expensive is $575. It is the same notice, running for the same four weeks, with the same legal effect either way.

The county's part: $26, a notary, and a slow mailbox

The Registrar-Recorder/County Clerk's fee page is one screen long. A first-time filing covering one business name and one registrant is $26. Each additional business name or additional registrant beyond the first is $5. A renewal is also $26, and the county's FAQ puts the point in the question itself so nobody has to ask twice: a refile is not cheaper.

Three doors lead to the same filing, and they cost different amounts of money and time. Filing online through the county's portal adds a $10.75 identity and credit-card processing fee. Paying by card at a counter adds $1.75. Filing by mail adds nothing but weeks — the FAQ says the mail procedure "may take 6-8 weeks," and mail is processed only at the Norwalk headquarters, not the district offices. In-person appointments are also Norwalk only.

Whichever door you use, one document trips people up. Section 17913 lets a county clerk require a notarized affidavit of identity from anyone who mails in a statement, and Los Angeles requires one. The county's filing page spells out the three versions: at the counter you show valid identification and complete the affidavit there; by mail you send it already notarized; and anyone filing on your behalf brings a notarized affidavit of identity and agent form plus their own ID. If the registrant is a corporation, an LLC, a limited partnership or a limited liability partnership, the county also wants a printout from the Secretary of State showing current existence and good standing, and says no other state evidence will be accepted.

One more thing worth knowing before you pick a county: section 17915 sends the statement to the clerk of the county where your principal place of business sits. If that's an apartment in Highland Park, this is your county.

Then you buy four weeks of newspaper

Section 17917 is the expensive sentence. Within 45 days after the statement is filed, you have to publish it in a newspaper of general circulation in the county where you filed, on the schedule set by Government Code section 6064 — once a week for four successive weeks, four insertions with at least five days between publication dates, running 28 days from the first one. Then the paperwork comes back to the county: subdivision (d) requires an affidavit showing the publication to be filed with the same county clerk within 45 days after the publication finishes. The county lists filing a proof of publication among its fictitious business name services, alongside the original filing.

None of that money goes to the county. All of it goes to a newspaper, and that is where the number stops being a number.

136 papers, 26 different prices, one identical notice

The county's publication page carries an alphabetical directory of papers that have filed court documentation of general circulation, each entry listing an address, a contact, a court case number and a fee. We counted 136 entries with a fee attached and sorted them. They resolve into 26 distinct prices:

$29 — Canyon News, Beverly Hills, listed as including the four weeks of publication. $30 — American Eagle News in Northridge, and the British Weekly in Santa Monica. $35 — the L.A. Metropolitan Gazette. $45 — seventeen titles, from the Alhambra Press to the Belmont Beacon. $65 — Our Weekly and the Antelope Valley Press. $75 — thirty-seven titles, the largest block on the list. $100 — the Beverly Press and four others. $119 — the Long Beach Press-Telegram. $120.50 — the Burbank Leader and four more. $148.80 — seventeen titles, including the Pasadena Star-News and the San Gabriel Valley Daily Tribune. $300 — the Epoch Times. $575 — the Los Angeles Times on Sundays, $491 the rest of the week.

The median is $75. Twenty-six of the 136 charge $50 or less; thirty-one charge $100 or more. And the middle of the list is less varied than 136 names make it look, because three shared operations price a third of it: the 37 titles at $75 include 25 that route to one email address and one suite on North Sepulveda Boulevard in Manhattan Beach, sixteen of the seventeen at $45 share one address on West Lime Avenue in Monrovia, and all seventeen at $148.80 share one address on West Huntington Drive in Monrovia and one self-service portal at scng.com. You are not choosing among 136 newsrooms. You are mostly choosing among a handful of legal-notice desks, and they don't charge the same.

Whether you can pick the cheapest paper on the list

This is the gray zone, and it's worth reading the code rather than guessing at it, because the two relevant sentences say different kinds of things.

The binding one is section 17917(a): the paper has to be a newspaper of general circulation in the county where the statement was filed. Every name on the county's directory clears that bar for Los Angeles County — that is what the directory is.

The other one is subdivision (b), and it is written as a preference rather than a command: "the newspaper selected for the publication of the statement should be one that circulates in the area where the business is to be conducted." Should. Then section 17918, which is the section with actual teeth in it, ends by carving that preference out: "For the purposes of this section, the failure to comply with subdivision (b) of Section 17917 does not constitute transacting business contrary to the provisions of this chapter." The county quotes that whole section, carve-out included, on its own general information page.

That is the entire body of law on the question. A notice in a paper that circulates where your customers are is what the code asks for; the sanction section says that missing that preference is not what locks the courthouse door. Read both before you spend $148.80 to satisfy a sentence that says "should."

The deadline the county's own pages can't agree on

Here is a real trap, and it is not your fault. The county's publication page says publication must happen "within 45 days of filing." The county's FAQ says publication must begin "within 30 days of filing." So does the county's general information page. Three pages on one website, two different deadlines.

The statute settles it at 45. It used to be 30: Senate Bill 1495, Stats. 2022, ch. 511, changed it effective January 1, 2023, and the Legislative Counsel's Digest describes the change in one line: the bill would instead give a registrant 45 days after filing to publish, and 45 days after the publication ends to file the affidavit proving it. Two of the county's pages are still printing the old number.

Work to 30 anyway. It's the tighter of the two, it's the one on the pages a clerk is most likely to be reading, and being early costs you nothing. The extra fifteen days are a legal backstop, not a plan.

The address you write on the form is a public record

The county's pages disagree here too, and this one is about your privacy rather than your calendar. The filing page says a registrant must now give a "business mailing address" rather than a residence address, effective January 1, 2024 — the change made by Assembly Bill 878, which the Legislative Counsel's Digest describes as requiring a business mailing address in place of a residence address on fictitious business name statements, abandonments and withdrawals. The general information page still instructs that all owners' "residence addresses must be listed."

The filing page is the current one. Use a business mailing address you're willing to see indexed, because a filed statement is a public record and a mailbox is cheaper than a correction. The same calculation applies one step later, when the city asks: our guide to L.A.'s business tax registration walks through what the city publishes about registrants on its open data portal.

What actually happens if you skip the newspaper

Nothing, for a while. There's no fine waiting, no letter, no inspector. Section 17918 does something quieter and worse. Anyone transacting business under a fictitious business name in violation of the chapter cannot bring an action in any California court on a contract made in that name — not, the section says, "until the fictitious business name statement has been executed, filed, and published as required."

Read that as a sequence, because it is one. Executed, filed, and published. A client who doesn't pay a $6,000 invoice made out to that same Alder Studio is a problem you can take to small claims court — but not until the notice has run. The operative word in that sentence is "until," so the bar lifts once the statement has been filed and published. The delay doesn't, which is why the $29 option matters more than it looks.

And section 17930 covers the other direction: executing, filing or publishing a statement you know to be false is a misdemeanor, punishable by a fine of up to $1,000.

The clocks that start once you're done

Five years, from the filing date. Section 17920 expires a statement five years from the date it was filed with the county clerk, and the county's renewals page says the same thing in the same words. Not five years from when it was published, and not the end of the fifth year. Put the date on a calendar the day you file it.

Forty days, if anything changes. The same section expires the statement 40 days after any change in the facts it states, and section 17910 requires a new statement after that change. A move, a new co-owner, a different business address: 40 days, and the old filing is gone.

No republication on a clean renewal. The county states it flatly: you are not required to publish a renewal in a newspaper. Section 17917(c) says the same for a refiling after expiration, as long as nothing in the expired statement has changed and you refile within 40 days of the expiration date. A withdrawal — removing one registered owner from a statement — does require publication, per the county's FAQ.

Three things this filing is not

It is not a business license. The county clerk's office says so on its own page and sends you elsewhere: to city hall in the city where you'll operate, or, for an unincorporated area of the county, to the Los Angeles County business license office at (213) 974-2011.

It is not a trademark. The same page points name protection to the U.S. Patent and Trademark Office. Filing a DBA tells the county who is behind a name. It doesn't stop anyone else from using it.

It is not required of nonprofits. The general information page exempts nonprofit corporations, organizations and associations from filing a fictitious business name statement at all.

The order to do it in

Count 40 days back from the day you started taking work, and if that date has passed, file today rather than reading further. File online if the $10.75 is worth skipping six to eight weeks of mail, and get the affidavit of identity notarized first if it isn't. The day the filing clears, open the county's newspaper directory and pick a price, not a masthead — the range is $29 to $575 for the same four weeks. Then set two reminders: day 30 to have the first insertion running, and five years out, to the day, from the date stamped on your filing.

Fees, deadlines and code sections above were checked on September 3, 2026 against the Los Angeles County Registrar-Recorder/County Clerk's fictitious business name general information, filing, publication, renewals, fees and FAQ pages, and against Business and Professions Code sections 17900, 17910, 17913, 17915, 17917, 17918, 17920 and 17930, Government Code section 6064, and the Legislative Counsel's Digests for Senate Bill 1495 (2022) and Assembly Bill 878 (2023). The newspaper prices are the fees the county prints beside each paper on its own directory and can change without the directory changing.
