Most people start a business in the wrong order. They fall in love with a space, sign something, and then discover what the space will and will not permit. The sequence below is deliberately boring, and it is the sequence that keeps money in the business rather than in a build-out that has to be undone.
Nothing here is legal or tax advice. Entity choice belongs to an attorney and a CPA, and every approval named below is administered by an agency with its own current rules. What follows is a map of the decisions and the order they belong in.
Step one: decide what the business actually is
Before any filing, write down three things in plain language: what you sell, who buys it, and how the money arrives. That description drives everything downstream. It determines which permits apply, which zoning categories fit, how much space you need, whether you handle food, whether you have employees, and whether customers come to you at all.
Operators who skip this step tend to describe the business by its aesthetic rather than its mechanics, and aesthetics do not map onto a permit application. A city planner does not need your brand story; a planner needs to know whether you are retail, service, food service, assembly, or something the code treats as a specific use.
Step two: choose a legal structure, with advisors
Sole proprietorship, partnership, limited liability company, corporation. Each allocates liability, tax treatment, and administrative burden differently, and the right answer depends on facts about you rather than facts about Claremont. This is the decision most worth paying for, because unwinding it later is more expensive than getting advice now.
Two practical consequences follow immediately. The structure determines what name you register and how, and it determines whether you need a separate federal tax identification number before a bank will open a business account. Get the bank account open early; commingling personal and business money is the single most common bookkeeping problem in a first year.
Step three: registrations before location
Several registrations are location-independent, and doing them first means the location clock is not running while you wait. Depending on structure and activity these commonly include state entity filing, a fictitious business name filing at the county level if you operate under a name other than your legal one, a federal employer identification number, and a state seller's permit if you sell tangible goods.
The seller's permit deserves its own attention because it carries continuing obligations rather than a one-time step. The registration and reporting cycle is laid out in the sales tax guide.
Professional and occupational licenses sit alongside these. If your trade is licensed by the state, that license is a prerequisite rather than a formality, and no local approval substitutes for it.
Step four: decide whether you need a storefront at all
This is the step most first-time owners skip, and it is where the largest amount of money is decided. Many businesses that assume they need commercial space do not, at least not in year one.
A home-based operation carries its own rule set and its own real limits, and those limits are specific rather than general; the categories are covered in the home-based business guide. A live-work arrangement is a different structure again, with its own approval path, described in the live-work guide. A temporary presence at a market or a pop-up is a third path, and it lets you test demand before committing to a lease.
Only after those options have been genuinely considered does a storefront search make sense.
Step five: the local business registration
Operating a business in the city generally requires registration with the city itself, and this applies whether you occupy a storefront, work from home, or work out of a vehicle. Contractors and service providers who work at customer sites are frequently surprised by this; the obligation attaches to doing business in the city, not to having a sign on a building.
The full sequence of local approvals, and the order they interlock in, is set out in the licenses and permits checklist. Confirm the current requirements and fees directly with the City of Claremont, because those change and no article should be your source for them.
Step six: match the space to the use, before signing
If you do need commercial space, the order inside this step matters as much as the step itself. Identify the space, then confirm that the zoning permits your use at that address, then confirm what approvals the change of use or the build-out will trigger, and only then negotiate.
A lease signed before the use is confirmed is a bet that the city will agree with you. Sometimes the bet pays. When it does not, you are paying rent on a space you cannot open. The clauses that decide the rest of the tenancy are covered in the storefront leasing guide, and an attorney should read the actual document.
Two obligations attach to the space rather than to you, and both are commonly discovered late. Accessibility requirements apply to places of public accommodation and are triggered by alterations as well as by new construction. And a food operation carries a health permitting layer that runs parallel to the city's process rather than inside it.
Step seven: the operating layer
Insurance, employment obligations, equipment taxes, and waste and delivery logistics are not launch-day items in most people's minds and all four are launch-day items in practice. A landlord will require evidence of insurance before delivering keys. A first employee triggers a whole compliance apparatus. Equipment owned on the assessment date is taxable business personal property.
None of these are hard individually. They are only expensive when discovered in the same week as opening.
The order in one line
Define the business, choose the structure with advisors, complete the location-independent registrations, decide whether you need space, register locally, confirm zoning and approvals before signing anything, then build the operating layer.

Frequently asked questions
What is the first step to opening a business in Claremont?
Write a plain-language description of what you sell, who buys it, and how payment arrives. That description determines your permit categories, your zoning fit, your space needs, and whether you need a storefront at all. Entity choice and registrations follow it rather than precede it.
Do I need a city business registration if I work from home?
In most cases the obligation attaches to doing business in the city rather than to occupying commercial space, so home-based operators and mobile service providers are commonly included. Confirm the current requirement and any home-occupation conditions directly with the City of Claremont.
Should I sign a lease before confirming zoning?
No. Confirm that the address permits your specific use, and learn what approvals a change of use or build-out will trigger, before signing anything. A lease signed first is a bet that the city will agree with your reading of the code, and losing that bet means paying rent on a space you cannot open.
Which registrations can I complete before I have a location?
Entity formation, a fictitious business name filing if you use one, a federal tax identification number, a state seller's permit if you sell tangible goods, and any state professional license are generally location-independent. Completing them early means the lease clock is not running while you wait on paperwork.
