How to start a business
in Costa Mesa.
Costa Mesa packs a top retail destination, a serious arts scene, and a dense cluster of creative businesses into a small footprint. Here is the practical sequence to register, license, and open, with the official links and where to get free help.
For its size, Costa Mesa punches well above its weight. South Coast Plaza is one of the highest-grossing shopping destinations in the country, the Segerstrom Center for the Arts anchors a real cultural scene, and the OC Fair and Event Center draws crowds all summer. Districts like SoBeCa, The LAB, and The CAMP, along with the 17th Street corridor, have made the city a hub for design, creative agencies, restaurants, and breweries. The audience here is design-literate and discerning, which sets a high bar for how a business presents itself.
That bar is the opportunity. A business that looks the part and is easy to find earns trust quickly in a market that rewards taste. Getting open cleanly, with the right license and permits, sets the foundation. Getting found afterward is the next job. This guide covers the first in detail, then points you to the second.
//The sequence
How to start a business in Costa Mesa, step by step.
This is the order that works for most new Costa Mesa businesses. When in doubt, run your address and business type through CalGold and it will list everything that applies to you.
- 1
Register the business and the name
Form your LLC or corporation with the California Secretary of State through bizfile, or stay a sole proprietor. If you operate under a name that is not your legal name, file a fictitious business name (DBA) with the Orange County Clerk-Recorder and publish it for four weeks.
- 2
Get your free EIN and any seller's permit
Get a free federal EIN from the IRS for banking and taxes. If you sell or lease physical goods, register for a free seller's permit with the CDTFA so you can collect sales tax.
- 3
Get your Costa Mesa business license
Costa Mesa requires a business license before you start, and the city runs it through an online application system. You can apply, pay, and renew online through the city's business license portal. Questions go to bl@costamesaca.gov or (714) 754-5235.
- 4
Confirm zoning and pull any industry permits
Confirm your location is zoned for your use before you sign a lease, then check CalGold for the permits your trade needs. Any food business, including a restaurant or brewery, also needs a health permit and inspection from the OC Health Care Agency.
- 5
Budget for the $800 California franchise tax
If you form an LLC or corporation, California charges a minimum $800 annual franchise tax through the Franchise Tax Board, owed even in a slow year. Plan for it from day one.
- 6

//By trade in Costa Mesa
Common Costa Mesa businesses, and the extra step each needs.
Restaurant or brewery
Costa Mesa's food and craft scene is a draw in its own right. Beyond the city license, you need the OC Health Care Agency permit and inspection, and breweries add state ABC licensing. Confirm the full set before you build out.
Retail or boutique
Get a CDTFA seller's permit to collect sales tax plus the city license. In the South Coast Plaza orbit and the design districts, presentation and being found both matter as much as the paperwork.
Creative or design agency
Agencies and studios mostly need the city business license, often run from a home or small office. The real early work is standing out and being found in a city full of creative competitors.
Professional or service business
These need the city license plus any state or professional license. A credible, well-built presence earns trust fast with this design-literate audience.
//When you are ready to be found
Getting open is step one. Looking the part is step two.
A design-literate audience judges fast
In Costa Mesa, a dated or generic presence gets dismissed quickly, while a credible, well-built one earns the click and the trust. Taste is not optional here.
Local search is the front door
Most first customers come from a Google search or the map pack. A complete profile, real reviews, and a fast, good-looking site do most of the work.

//Common questions
Things we get asked first.
Do I need a business license in Costa Mesa?
Yes. Costa Mesa requires a business license before you start. The city runs applications, payments, and renewals through an online business license portal, and questions go to bl@costamesaca.gov or (714) 754-5235.
How do I open a restaurant in Costa Mesa?
Beyond the city business license, every food facility needs a health permit and a pre-opening inspection from the OC Health Care Agency Environmental Health division. A brewery or bar adds state ABC licensing, so confirm the full set before you build out.
Can I run a creative agency from home in Costa Mesa?
Often yes, and you still need the city business license. Confirm with the city that a home occupation is allowed at your address and that your use stays within the residential rules.
What is the $800 tax people forget about?
If you form an LLC or corporation, California charges a minimum $800 annual franchise tax through the Franchise Tax Board, owed even in a slow year. New owners routinely forget it, so plan for it from day one.
Can you guarantee customers once I open?
No, and anyone who guarantees rankings or a fixed number of leads is selling fiction. We promise honest work and reporting tied to revenue, and we make you the credible, findable option when a Costa Mesa customer searches.
About Mining Wells
We're on a mission to fix bad marketing.
Maybe:
- You are spending thousands on marketing tools, ads, and your website, with zero revenue increase to show for it.
- Every campaign you have tried gets minimal results.
- You have a great product that nobody seems to find.
- You are getting interest, but it never converts to a sale.
- You have a low retention rate.
- You have been paying a marketing agency for over a year and have not seen results.
You are not alone. Many founders and leaders live with the results of bad marketing without ever finding the reason.
And often that is because it can be many reasons. Sometimes it is the wrong ICP, sometimes the wrong messaging, sometimes the wrong targeting chasing impressions.
We are here to take the hard guesswork out and provide that clarity before it is too late.
At Mining Wells, we help founders and leaders grow their businesses the right way.
