The beliefs that cost money
Most expensive mistakes in small business start as reasonable assumptions. They sound sensible, nobody contradicts them, and they only fail at the point where a lease is signed or a permit is refused.
Here are the ones that come up most, and what to check instead.
Myth: if it is a commercial space, my business can go there
Zoning distinguishes between uses, and permitted uses vary by parcel. Retail, food service, personal services, medical or treatment uses, instruction, office, and production are treated differently, sometimes with different parking expectations and sometimes requiring specific approval.
A vacant unit is not evidence that your use is allowed in it. Take the specific address and the specific use to the City of Claremont before committing.
Myth: the previous tenant did it, so I can
Uses are sometimes approved with conditions, approved under older rules, or altered over the years without approval. A change of tenant or a change of operation can bring that history into view.
Approvals also are not always personal to a space in the way people assume. Ask the city what applies TODAY, for YOUR use.
Myth: I can take over the lease if I buy the business
Assignment usually requires landlord consent, and the lease sets the standard for that consent. Some leases restrict transfers. Options to extend may be personal to the current tenant. A landlord may treat an assignment as an opportunity to renegotiate.
This is why the lease is the first document to read in any business purchase, as set out in buying an existing business.
Myth: a commercial lease is like a residential lease
It is not. Commercial leases commonly allocate responsibility for building systems, roofing, parking areas, accessibility upgrades, and restoration of the premises at the end of the term. They frequently run for years and may bind you personally through a guaranty.
Have an attorney read it. Our leasing guide covers the clauses that decide the economics.
Myth: the accessibility question is the landlord's problem
Accessibility obligations under federal and state law apply to places of public accommodation, and alterations can trigger requirements. Who pays is a matter for the lease; whether the obligation exists is a matter of law.
Treat this as a legal question during diligence, with an attorney and a qualified accessibility professional, rather than an assumption that someone else handled it.
Myth: a home business is unregulated
Home occupation rules generally permit business activity in a residence within limits on customer visits, signage, employees, storage, and neighbourhood impacts. Registration still applies, and a home address does not exempt a business from a city licence, a state seller's permit for taxable sales, or employer registration.
The realistic boundaries are in home-based businesses.
Myth: parking is only about how many spaces exist
Parking requirements generally attach to the USE, so a space that suited a low-traffic office may not suit a use with high customer turnover. Separately, the lease decides what parking, if any, is allocated to your premises and who maintains it.
Three different questions, three different answers, worked through in the parking article.
Myth: signage is a design decision
Sign type, size, placement, illumination, and materials are regulated, and in areas with protected character the review is more involved. Ordering a sign before confirming what is allowed is a well-trodden way to buy something twice.
Myth: I can open shortly after I get the keys
Plan review, permits, inspections, contractor scheduling, equipment lead times, and utility connections occupy a period that produces no revenue, and they run more sequentially than people expect. Food service adds county review on top.
Ask the city and your contractor for current timelines, then fund the gap. This is the most common cause of a business opening underfunded.
Myth: a busy market stall proves a shop will work
Event traffic and everyday traffic behave differently. A pop-up genuinely tests demand, pricing, and your ability to produce at volume, all of which is valuable, but it does not forecast a quiet Tuesday in a fixed location.
How to run the test properly is in pop-ups and markets.
Myth: the best location is the busiest one
Only for businesses that depend on discovery. Appointment-based services, production, and fulfilment gain nothing from expensive frontage, and paying for footfall you cannot convert is one of the quietest ways to run out of money.
Match the space to the demand pattern, as in choosing a location.
Myth: buying premises is always better than renting
Ownership removes renewal risk and can suit businesses that stay put and improve heavily. It also ties up capital the business may need, adds maintenance responsibility, and reduces flexibility if the business changes.
It is a genuine trade, examined in buying commercial property.
Myth: I will sort the structure and the books later
Entity structure affects liability and tax, and unwinding it later is harder than choosing carefully once. Records that are informal or mixed with personal spending create problems at tax time, at loan applications, and above all at sale, when a buyer's accountant must be able to verify what the business does.
Attorney for structure, CPA for books, both early.
The general rule
Anything that determines whether you can operate, where, and at what obligation deserves confirmation from the responsible body IN WRITING, not from a landlord's summary, a neighbouring owner's memory, or an article, including this one.

Frequently asked questions
Can any business open in any vacant commercial unit?
No. Permitted uses vary by parcel, and categories like retail, food service, treatment uses, instruction, office, and production are treated differently. Confirm the specific address and specific use with the City of Claremont.
Does a lease transfer automatically with a business sale?
Usually not. Assignment generally requires landlord consent on the standard set by the lease, some leases restrict transfers, and options to extend may not carry over to a new tenant.
Are home-based businesses exempt from registration?
No. Home occupation rules set limits on visits, signage, employees, and storage, and a home address does not remove the need for a city business licence, a state seller's permit for taxable sales, or employer registration.
Is the busiest location always best?
Only for businesses that rely on being discovered. Appointment-based services, production, and fulfilment gain little from expensive frontage, and paying for footfall you cannot convert is a common way to run short of capital.
