A DBA ("Doing Business As," also called a fictitious business name, assumed name, or trade name) is a registration that allows you to operate a business under a name other than your legal personal or entity name. For cleaning businesses, it comes up in two main situations: sole proprietors who want a professional trade name, and LLCs that want to market under a different name than their registered entity name.
The process is straightforward, the cost is low, and the filing takes 15–30 minutes. This article covers when you need one, how to file it, and the distinction between a DBA and an LLC that many operators get wrong.

When a DBA Is Required
You need a DBA when the name you want to operate under does not match your legal name (for sole proprietors) or your registered entity name (for LLCs and corporations).
Examples that require a DBA:
- John Smith, sole proprietor, wants to operate as "Capitol City Janitorial". DBA required
- "Smith Enterprises LLC" wants to market cleaning services as "Fresh Start Commercial Cleaning". DBA for LLC required
- A partnership where two individuals want to operate as "Metro Office Cleaners". DBA required
Examples that do not require a DBA:
- John Smith, sole proprietor, operating as "John Smith Cleaning Services", no DBA required
- "Capitol City Janitorial LLC" operating under that exact name, no DBA required
Practical note: Most banks require a DBA certificate (or LLC formation documents) to open a business checking account in a trade name. Cash from clients paying "Capitol City Janitorial" cannot be deposited into a personal account without a DBA on file.
DBA vs. LLC: The Critical Difference
A DBA is purely a name registration. It provides:
- A legal right to use the trade name in your jurisdiction
- The ability to open a bank account in the trade name
- A public record of the business-to-owner relationship
A DBA does not provide:
- Liability protection (personal assets remain exposed)
- A separate tax entity
- Any protection for the business name in other counties or states
An LLC provides legal separation between personal and business assets. If a client files a lawsuit against "Capitol City Janitorial" operated as a sole proprietor DBA, they are suing you personally. If it's an LLC, the lawsuit targets the LLC's assets, not your home, car, or personal savings account.
For a cleaning business, the practical recommendation is: file an LLC, then register a DBA under the LLC if you want a different trade name. This gives you both the name flexibility and the liability protection.

How to File a DBA
Step 1: Check name availability Search for existing DBAs and business names in your county (and state, for LLCs). Most counties have an online search tool on the county clerk's website. Avoid names that are too similar to existing businesses in your market.
Step 2: Complete the fictitious business name statement Most counties have a one-page form available on the county clerk's website. Information required: trade name, business type (sole prop, LLC, etc.), owner's legal name, business address, start date.
Step 3: File with the county clerk File in the county where your principal business address is located. In most states, this means in-person or by mail. An increasing number of counties accept online filing. Fee: $10–$100.
Step 4: Publication (where required) California, New York, and a handful of other states require publishing a DBA notice in a local adjudicated newspaper for a set number of consecutive weeks (California: 4 consecutive weeks). Publication cost varies by newspaper: typically $40–$200. Keep the affidavit of publication. It's required to complete the filing.
Step 5: Obtain the DBA certificate After filing (and publication where required), the county clerk issues a DBA certificate. This document is what banks require to open an account in the trade name.
Renewal: Most DBAs expire after 5 years and must be renewed. Mark the expiration date in your calendar, operating under an expired DBA in a state that requires renewal is a technical violation.
State-Specific Notes
California: County-level filing ($26) plus 4-week newspaper publication ($40–$200). Proof of publication filed with the county clerk within 30 days of last publication. DBA expires after 5 years.
New York: County Clerk filing ($25–$100) plus 6-week publication in two newspapers designated by the county clerk. Affidavit of publication required to complete the filing. New York City has a separate NYC DBA process.
Texas: County Clerk filing ($25). No publication requirement. Trade name assumed names are county-specific, file in every county where you do business.
Florida: Division of Corporations at SunBiz.org, $50 filing fee. Statewide registration (not county-specific). Renewable every 5 years.
Illinois: County Clerk filing ($30–$100). No publication requirement.
DBA for an Existing LLC
An existing LLC can register a DBA to operate under an additional trade name. The process is the same as for a sole proprietor, file with the county clerk, attach the LLC formation documents as proof of the underlying entity, and obtain the DBA certificate.
Use cases for cleaning businesses:
- "Smith Services LLC" files a DBA for "North Austin Commercial Cleaning" to use a geographically specific brand in one market
- An LLC adding a residential cleaning division files a DBA for the residential-branded name
- An operator acquiring a small competitor files a DBA to continue operating under the acquired company's name
Frequently Asked Questions
Does a cleaning business need a DBA?
Only when you operate under a name that differs from your legal personal name as a sole proprietor, or from your LLC's registered name. If your LLC is Capitol City Janitorial LLC and your trucks say Capitol City Janitorial, you do not need one. The LLC name already serves as the trade name. The filing exists to connect a public-facing name back to whoever is legally responsible for it.
What does a DBA cost to file?
Expect $10–$100 at the county clerk. States that still require newspaper publication, California and New York among them, add another $40–$200 for the notice, which is often the larger half of the total. Check the publication rule before you budget, since it varies by state and sometimes by county.
Is a DBA the same as an LLC?
No, and the difference shows up the first time a claim lands. A DBA is a name registration and provides no liability protection at all. An LLC is a legal entity that separates your personal assets from business debts and claims. Filing a DBA over a sole proprietorship gives you a name to market under and nothing more than that.
Can I open a business bank account with just a DBA?
Usually yes. Most banks will open a business checking account on a DBA certificate plus your personal ID. If the DBA is filed under an LLC, some banks also want the underlying entity documents, so bring the formation paperwork to the appointment rather than making a second trip.
