The hardest part of opening a phở shop is not in the kitchen. It is the order of the paperwork, because the law dictates what has to be finished before what, and getting the order wrong means the rent keeps running while the shop is not yet allowed to sell a single bowl.
This guide follows that order. Every figure and every rule is sourced so you can check it yourself, because fees and statutes change every year, and what follows is what is in force in August 2026. The concrete examples come from California, home to 770,000 people of Vietnamese origin, more than any other state. In other states the structure of the process is similar, but the numbers and the agencies in charge will differ.
California law says the plans must be approved before you break ground, and that a food facility may not open for business without a valid permit. The lease does not wait for either one.
The numbers worth knowing before you spend
According to the U.S. Small Business Administration (SBA), averaged over the period from 1994 to 2022, 67.7% of new establishments survived at least two years, and 49.2% survived five years.
But the other side of that same dataset is rarely mentioned, and it matters more: among establishments that reach the five-year mark, 69.5% go on to ten years. The risk is loaded at the front. Anyone who gets through the first few years sees their odds of lasting improve markedly, so the whole point of preparation is surviving that early stretch.
Step 1: Choose a legal structure, and know its annual cost
The legal structure decides who is liable when the shop is sued, for instance if a customer is poisoned or slips inside.
| Structure | Personal liability | Who the SBA says it suits |
|---|---|---|
| Sole proprietorship | The owner can be held personally liable for the debts and obligations of the business | Low-risk businesses, and owners testing an idea before forming something more formal |
| Partnership | Unlimited personal liability unless structured as a limited partnership | Businesses with multiple owners |
| LLC | Personal assets such as your vehicle, house and savings accounts are shielded in most instances | Medium- or higher-risk businesses, owners with personal assets to protect |
| Corporation | Owners are not personally liable | Businesses that need to raise money, or plan to be sold later |
The SBA puts restaurants in the category where an LLC is the sensible choice, since this is a medium- to higher-risk trade and the owner's personal assets are shielded in most instances.
One cost is routinely missed. In California, every LLC doing business or organized in the state must pay an annual tax of $800, and the Franchise Tax Board (FTB) states plainly that this is due every year until the LLC is cancelled, including years with no business at all. There used to be a first-year exemption, but it applied only to LLCs registered from 1/1/2021 to before 1/1/2024. An LLC formed in 2026 pays from its first year. On top of that, once California income reaches $250,000 there is an additional LLC fee of $900, and that fee rises in bands with income.
Step 2: The order of the paperwork, the part that decides the whole plan
The Employer Identification Number (EIN) is the fastest step and worth doing early, because opening a business bank account and running payroll both require it. The Internal Revenue Service (IRS) issues an EIN free and immediately through its online application, and warns on its own page that you never have to pay a fee for one. Note one limit: each responsible party can obtain only one EIN per day.
The two statutes below are the most important part of this guide.
First, the California Health and Safety Code, section 114380, requires a person proposing to build or remodel a food facility to submit plans and specifications to the enforcement agency, and to receive plan approval before starting any new construction or remodeling. Approval first, construction second. Not construction and then an application.
Second, section 114381 of the same code carries one short sentence: a food facility shall not be open for business without a valid permit.
Set those two beside a lease and the trap becomes visible. The plans have to clear a review, may have to be corrected and resubmitted, only then can the build proceed, and only then can the operating permit be issued. Rent is payable throughout. This is why the time to negotiate a clause letting you walk away if the plans are not approved is before signing.
There is one more detail few people know, for anyone buying a running restaurant. Also under section 114381, an operating permit is nontransferable, and is valid only for the named person, the location and the type of activity on it. Buying an open restaurant does not mean buying its permit. The buyer has to obtain a new permit in their own name.
Step 3: The kitchen has to be built to code, not to taste
This is the line item that overruns most often when the space has never been used for cooking. The construction guideline from the Los Angeles County Department of Public Health is specific, and these requirements are part of the plans that must be approved.
On floors, preparation and warewashing areas must use smooth, durable material impervious to water, grease and acid, for example quarry tile or troweled epoxy. Painted floors and vinyl composition tile are not acceptable. The floor-to-wall junction has to be coved.
On extraction, the ventilation plans must show front and side elevations of the exhaust hood, duct details up to the roof fans, static pressure calculations and manufacturer specification sheets for the exhaust fan, the make-up air fan and the hood filters. Once installed, an air balance report is required as well. That is why a compliant hood for a phở shop is not an equipment purchase but a designed construction item.
On grease, the guideline states that a grease trap or interceptor may not sit in a food or utensil handling area unless the enforcement agency specifically approves it, and must be easily accessible for servicing. The specific sizing and siting requirements are set by the city building department or the local sanitary or public works agency, which makes this the question to ask before choosing a space at all.
Why is advice from a relative in another state so often wrong? Because the Food and Drug Administration (FDA) Food Code is a model, not law. Each state and locality uses that model to write its own rules. The most recent full edition is the 2022 edition. Which means experience opening a shop in Houston is only good for Houston.
Step 4: Kitchen staff need paperwork too, and the owner pays for it
Two different documents, easily confused.
The first is a food safety certification for management. Under section 113947.1, a facility that prepares or serves non-prepackaged potentially hazardous food must have at least one owner or employee who has passed an approved and accredited food safety certification examination. That person need not be present during all hours of operation, but may not serve as the certified person for another facility.
The second is a food handler card for anyone handling food directly. Under section 113948, an employee must obtain the card within 30 days of the date of hire, and the card is valid for three years from issuance even if the holder changes employers. The law also requires that at least one course and examination cost no more than $15, including the card.
The point many owners have not caught up with: since 1/1/2024, under SB 476 amending section 113948, the employer must cover the cost of obtaining the card, must treat time spent training and testing as compensable hours worked, and must relieve the employee of all other duties during the training. The law also forbids an employer from conditioning employment on already holding a card. In other words, this is now the shop's expense, and it belongs in the payroll budget from day one.
Step 5: Alcohol, the line item most often underestimated
In California, a beer-and-wine licence falls in the non-general group, while a licence to sell full spirits is a general licence. The cost gap between the two is large.
According to the application fee schedule of the California Department of Alcoholic Beverage Control (ABC), an application for a non-general licence, including the Type 41 for an eating place serving beer and wine, carries a fee of $1,135. An application for a new general licence under the priority process, including the Type 47 for an eating place serving everything, carries a fee of $19,840. Both also require the annual fee to be paid when the application is filed.
That gap is not only money. ABC states that the number of general licences is limited by each county's population, and that for most general types, applications for a new licence are accepted only once a year through a public lottery known as the priority process. So a new restaurant that wants to serve spirits may have to wait out a full annual cycle, or buy a licence from someone else. The application fee for a person-to-person transfer including a general licence is $1,565, before the market price of the licence itself.
One more item for the budget: ABC is authorized to raise fees annually with inflation. Fees for 2026 rose 2.72%, and from 1/1/2027 they rise a further 3.31% above the 2026 amounts.
Step 6: Capital, and this year's beef problem
For a phở shop the largest ingredient cost is currently the fastest-rising one, and that has to be handled in working capital rather than in the menu price.
According to the Economic Research Service (ERS) of the U.S. Department of Agriculture, beef and veal prices in June 2026 were 11.8% higher than a year earlier, and the forecast for 2026 as a whole is an increase of 10.7%. The reason given is that the U.S. cattle herd has fallen to its lowest level in 75 years, leaving wholesale beef prices at all-time highs for this point in the year.
Meanwhile the food-away-from-home category, meaning restaurants and other foodservice, was only 3.4% higher in June 2026 than a year earlier, with a full-year 2026 forecast of 3.5%.
Those two figures state the phở shop owner's problem: the main input is rising roughly three times faster than the whole industry has been able to raise prices. An owner pricing a bowl off last season's beef cost will watch the margin thin without understanding why.
The tool for answering how much capital is needed comes from the SBA. Its break-even formula is fixed costs divided by the difference between the selling price per unit and the variable cost per unit.
Try it on a small shop. The figures below are assumed, to illustrate the arithmetic rather than to represent an industry average. Say fixed costs per month, covering rent, wages and utilities, come to $24,000; a bowl of phở sells for $16 and its variable cost in ingredients and packaging is $6. The contribution per bowl is then $10, and the break-even point is 2,400 bowls a month, or roughly 80 bowls a day, before other dishes and drinks.
Only from that number can the working capital question be answered: if the shop sells half its break-even volume for the first three months, it loses about $12,000 a month, so it needs roughly $36,000 in cash on hand just to get through those three months, on top of everything spent on construction and equipment. This is the reserve many owners fail to set aside, and it is why a shop runs out of money at exactly the moment customers start arriving.
Step 7: Funding, formal loans and hụi
The SBA's 7(a) loan is the most common formal channel for a restaurant. The maximum is $5 million, usable for working capital, acquiring or improving premises, purchasing and installing equipment, and buying an existing business.
Two things to know before applying. First, the SBA does not lend directly: the agency states that a borrower always works with the lender rather than with the SBA. Second, eligibility includes a criterion that is rarely mentioned, namely that the borrower must be unable to obtain comparable credit on reasonable terms from other sources. This is a programme for files a commercial bank has not yet taken, not a subsidised loan available to everyone.
Hụi, the rotating savings arrangement, remains common in the community because it is quick and needs no paperwork. But the difference in protection has to be seen clearly. Money deposited at a bank is insured by the Federal Deposit Insurance Corporation (FDIC), automatically and up to at least $250,000 at each member bank, covering checking, savings and certificates of deposit. Money handed to a hụi group is not a bank deposit, so it has none of that backing. If the group collapses, the only thing left to pursue is whatever the parties wrote down. So if hụi is used at all, treat it as a small supplementary source and put the amount, the schedule and the recipient in writing.
Family on the payroll: where you save, and where you don't
Employing relatives is very common in Vietnamese restaurants, and the tax code does contain real concessions, but only if the form is right.
According to the IRS, wages paid to a child under 18 working for a parent's sole proprietorship are not subject to social security and Medicare taxes, and federal unemployment tax does not apply until the child turns 21. Income tax withholding still applies as for any employee. And the crucial point: if the business is a corporation, or a partnership with a partner who is not the parent, then all payroll taxes apply regardless of age. In other words, the legal structure chosen in step 1 also decides the payroll bill here.
On minimum wage, from 1/1/2026 California's rate is $16.90 an hour for all employers not otherwise covered by a higher industry or local rate. Many cities set their own higher rate, so the city's own ordinance has to be checked. A parent, spouse or child of the employer is exempt from the state minimum wage.
One thing is widely misunderstood. The $20 an hour rate that received so much coverage applies only to limited-service restaurants in chains of at least 60 establishments nationwide. A family phở shop is not covered, and pays the state or city rate instead.
A word is needed about paying relatives cash off the books. The concessions above are precisely the reason to run proper payroll for family members, because those concessions only exist where there are payroll records. Paying by hand with no paperwork forfeits the benefit and leaves exposure if there is ever a tax examination, or when that relative needs to prove income.
Location: two strategies, two different problems
Population figures make choosing a site less a matter of instinct. According to the Pew Research Center, an estimated 2.3 million people in the United States identified as Vietnamese in 2023. California has 770,000 and Texas has 310,000. The three largest metropolitan concentrations are Los Angeles with 350,000, San Jose with 145,000 and Houston with 140,000.
Opening in an area dense with Vietnamese residents means a ready audience who know the food and word of mouth that travels fast, but the competing restaurants are thickest in exactly those areas. Opening where there are few Vietnamese residents can make the shop the only Asian option in the district, but the menu and the way dishes are explained have to be adjusted for customers who do not know them, and community word of mouth cannot be relied on for the early months.
The thing worth doing before signing a lease is to use both of those numbers: count the Vietnamese restaurants already open within a ten-minute drive, then compare that against the population inside the same radius.
Mistakes to avoid
Signing a long lease before the plans are approved, when the law requires approval before construction.
Assuming that buying a running restaurant means buying its permit.
Choosing a space never used for cooking without first asking about the hood and the grease interceptor.
Leaving California's $800 LLC annual tax out of the first-year budget.
Pricing dishes off last season's ingredient costs while beef rises three times faster than the industry raises prices.
Paying relatives cash off the books, and forfeiting the tax concessions the law grants family labour.
Opening a restaurant remains a familiar route into business for many Vietnamese American families. The point of this guide is not that it is harder than you think, but that the hard part sits somewhere other than where you think. Cooking well is necessary. The order of the paperwork, a budget that reserves working capital, and a payroll run properly from the start are what decide whether the shop is still open in three years.
