Legal Requirements for Opening a Brick-and-Mortar Store

Opening a brick-and-mortar store means clearing a specific set of legal requirements before you unlock the doors. You'll need to register your business, get an Employer Identification Number (EIN), secure zoning approval, obtain local permits, and meet building safety standards. The exact list depends on your location and industry, but these are the core steps every physical retail business needs to address.

Before you open a physical location, you need a registered business entity. The structure you choose — sole proprietorship, LLC, or corporation — affects your personal liability, taxes, and how you sign a commercial lease.

Sole proprietorships don't require formal state registration, but they offer no liability protection — meaning your personal finances are fair game if the business is sued. An LLC or corporation gives you a legal separation between you and the business. To form an LLC, file Articles of Organization with your state's Secretary of State office. To form a corporation, file Articles of Incorporation. Both are handled at the state level, not federal.

Most landlords require a registered business entity before they'll sign a commercial lease with you. Getting this done first removes a common bottleneck.

An Employer Identification Number (EIN) is a 9-digit number the IRS uses to identify your business for tax purposes. You need one to open a business bank account, hire employees, and file most business tax returns — all of which come with running a physical store.

LLCs, partnerships, and corporations are required to have an EIN. Sole proprietors without employees can use their Social Security Number instead, but an EIN keeps your personal number off business documents and is worth getting regardless.

EIN applications are free and processed immediately when you apply online through the IRS website. The online application is available Monday through Friday, 7 AM – 10 PM ET.

Zoning laws determine what types of businesses can operate in a given location. Local governments divide land into commercial, residential, and industrial zones — and not every commercial zone allows every type of retail business.

Check zoning before you sign a lease, not after. Contact your city or county planning department to confirm the address is zoned for your type of business. Some areas have historic preservation overlays that restrict exterior changes — a detail that catches retail owners off guard when they want to add signage or update a storefront.

If the location isn't zoned for your use, you can apply for a variance or conditional use permit — but that process takes time and isn't guaranteed. Build zoning confirmation into your site selection process before you commit.

A commercial lease is a legally binding contract that sets the terms of your tenancy — rent, duration, renewal options, and who pays for what. Unlike residential leases, commercial leases are heavily negotiable and vary widely in structure.

The 3 most common lease types are gross leases, net leases, and modified gross leases. A gross lease bundles rent, utilities, and maintenance into one monthly payment. A net lease (sometimes called a triple net or NNN lease) charges base rent plus a share of property taxes, insurance, and maintenance costs separately. A modified gross lease splits those costs somewhere in between. Each structure shifts financial risk differently between landlord and tenant.

Have a lawyer with commercial real estate experience review the lease before you sign. The terms around personal guarantees, build-out responsibilities, and early termination clauses are where most first-time retail tenants get caught out.

Most brick-and-mortar stores need at least a general business license from the city or county where they operate. Beyond that, the permits you need depend on your industry and location.

Common permits for retail stores include a seller's permit to collect and remit sales tax, a sign permit if you're installing exterior signage, and a health permit if you're selling food or perishable goods. Businesses selling alcohol need a state liquor license, which involves a separate application process through your state's alcohol control board.

The SBA's business license and permit tool is a good starting point for figuring out what applies to your location and industry. Your city or county clerk's office can confirm what's required locally.

A certificate of occupancy (CO) is a document issued by your local building authority that confirms the space meets building codes and is safe to use for its intended purpose. You need one before you open to the public.

If you're moving into an existing retail space without major renovations, the landlord may already have a CO on file. If you're doing a build-out or significant renovation, you'll need to pull building permits, pass inspections for electrical, plumbing, fire safety, and structural work, and then receive a new CO. Fire safety requirements — exits, extinguishers, sprinkler systems, and alarm systems — are a common inspection focus.

Requirements vary by jurisdiction. Check with your local building department early — inspection timelines can add weeks to your opening schedule if you don't plan for them.

If you're selling tangible goods at a physical retail location, you have sales tax nexus in that state — which means you're required to register for a sales tax permit and collect sales tax from customers.

Sales tax registration is handled through your state's department of revenue or taxation, not the IRS. Most states require you to register before you make your first taxable sale. The registration process and permit name vary by state — some call it a seller's permit, others a sales tax license or resale certificate.

A tax professional can help you figure out your collection and remittance obligations, especially if you also sell online and have customers in multiple states.

A physical store carries risks that an online-only business doesn't — customers on your premises, inventory on-site, and employees working in the space. Insurance isn't optional for most retail businesses.

General liability insurance covers claims of bodily injury or property damage to third parties — for example, a customer who slips and falls in your store. Many local governments require proof of general liability coverage before issuing a business license. If you have employees, workers' compensation insurance is required by law in every state except Texas, where it's optional.

Depending on what you sell, you may also need product liability coverage. If you handle customer data — credit cards, email addresses, loyalty program information — cyber liability insurance is worth considering.

The Americans with Disabilities Act (ADA) requires that places of public accommodation — which includes retail stores — be accessible to people with disabilities. This applies to new construction and, in many cases, to renovations of existing spaces.

Parking is one of the most specific ADA requirements. For lots with 1–25 total spaces, at least 1 must be accessible. Accessible spaces need to be at least 96 inches wide with an adjacent access aisle at least 60 inches wide. At least 1 in every 6 accessible spaces must be van-accessible, with an access aisle at least 96 inches wide. All accessible spaces must be marked with the International Symbol of Accessibility.

Interior accessibility — door widths, aisle clearances, counter heights, restroom access — is governed by ADA Standards for Accessible Design. A contractor familiar with ADA compliance can flag issues during your build-out planning before they become expensive fixes.
