How to start a business
in Tustin.
Tustin sits right in the middle of Orange County, where Old Town's walkable First Street meets the fast-growing Tustin Legacy district on the old air base. Here is the practical sequence to register, license, and open, with the official links and where to get free help.
Tustin is really two markets stitched together. Old Town Tustin, along First and Main, keeps a small-town main street feel with independent restaurants, salons, and shops that regulars walk to. A few miles south, the old Marine Corps Air Station has become Tustin Legacy, where The District at Tustin Legacy anchors big-box retail and dining next to thousands of new homes, offices, and the two landmark blimp hangars that still define the skyline.
Sitting where the 5 and the 55 cross, Tustin pulls customers from Santa Ana, Irvine, Orange, and North Tustin, so your buyer might be an Old Town local on foot or a family that just moved into Tustin Legacy. Each finds you differently. Getting open cleanly, with the right license and permits, is the first step. Getting found afterward is the second. This guide covers the first in detail, then points you to the second at the end.
//The sequence
How to start a business in Tustin, step by step.
Tustin publishes its own starting-a-business guide, linked in the first step. Here is the full order, including the county and state pieces that the city guide assumes you already know.
- 1
Plan and confirm your location works
Start with Tustin's own starting-a-business guide, then confirm your address and business activity are allowed under the city's zoning before you sign anything. Tustin has every business complete a Zoning Questionnaire, so verify land use up front with the Planning Division at (714) 573-3140. Confirming it early is the cheapest insurance there is, especially in an older Old Town storefront or a new Tustin Legacy space.
- 2
Register the business and the name
Form your LLC or corporation with the California Secretary of State through bizfile, or stay a sole proprietor. Either way, if you use 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.
- 3
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.
- 4
Get your Tustin Business License
Tustin requires every business in the city to hold a Business License, also called a Business Tax Certificate, before you start operating. You can apply online at any time, and the certificate is typically issued within about two weeks of a completed application. The tax amount depends on your business, so confirm your exact cost, plus the small state fee added to every license, with the Finance Department at (714) 573-3144 or businesslicense@tustinca.org. City Hall is at 300 Centennial Way.
- 5
Pull any industry permits
Run your business type through CalGold to see every permit that applies. If you are opening any food business, you also need a health permit and inspection from the OC Health Care Agency before you can serve a single customer.
- 6
Budget for the $800 state tax, then get free help
If you formed an LLC or corporation, plan for California's $800 minimum annual franchise tax. Then lean on the free experts: SCORE Orange County and the OCIE SBDC both offer no-cost consulting to Tustin businesses.

//By trade in Tustin
Common Tustin businesses, and the extra step each needs.
Old Town restaurant, cafe, or bar
Old Town Tustin along First and Main favors independent food and drink with loyal walk-in regulars. Beyond the city Business License, you need the OC Health Care Agency food permit and inspection, and any alcohol license runs through the state ABC. Older buildings can mean tenant improvements, so loop in Building at (714) 573-3131 early.
Tustin Legacy or District retailer
The District at Tustin Legacy and the new neighborhoods around the hangars bring steady retail and service demand. Paperwork is usually the Business License plus a seller's permit, but new construction can carry sign approval and tenant-improvement steps, so confirm those before your build-out.
Professional or service firm
Tustin's mix of offices near the 5 and 55 supports plenty of B2B and professional practices. These mostly need the Business License plus any state or professional license. Credibility and being found are the real early challenges here, not the paperwork.
Home-based business
Tustin licenses home-based businesses too, so do not skip it. You will also complete a Home Occupation Questionnaire. Confirm a home occupation is allowed at your address, keep client traffic and signage within the rules, and you are set.
//When you are ready to be found
Getting open is step one. Getting found is step two.
Tustin is several markets at once
Old Town walk-ins, Tustin Legacy families, and nearby offices all search differently. A clear web presence and local search strategy is what turns a specific Tustin audience into your customers.
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 site do most of the work in a central OC market this competitive.

//Common questions
Things we get asked first.
Do I need a business license in Tustin?
Yes. Tustin requires a Business License, also called a Business Tax Certificate, for every business operating in the city, including home-based ones. You apply online, and a certificate is typically issued within about two weeks. The tax depends on your business, so confirm your exact cost with the Finance Department at (714) 573-3144.
How do I open a restaurant or bar in Tustin?
Beyond the Tustin Business License, every food facility needs a health permit and pre-opening inspection from the OC Health Care Agency, and serving alcohol requires a license from the state ABC. Old Town's older buildings can require tenant improvements, so start with Planning and Building early.
Can I run a business from my home in Tustin?
Yes, and you still need the Business License plus a Home Occupation Questionnaire. Confirm a home occupation is allowed at your address, and keep client visits, parking, and signage within the city's rules.
How much does a Tustin Business License cost?
It depends on your business, since Tustin sets the business tax by the nature and size of the business, and a small state fee is added to every license. Contact the Finance Department at (714) 573-3144 or businesslicense@tustinca.org for your exact amount before you file.
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. What we can do is make you the credible, findable option when a Tustin 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.
