Commercial Lease Basics: What Every Small Business Owner Should Know

Oct 29 / Sean Snider
Leasing a commercial space is one of the biggest commitments a small business will make. The right lease can set you up for success, while the wrong one can hold you back for years. Here’s a roadmap to help you understand what to look for, what to avoid, and how to protect your business. 

As we get started, I want to make sure readers know that the information provided in this blog post is for general educational and informational purposes only and should not be considered legal, financial, or professional advice. Readers are encouraged to consult with a qualified attorney, real estate professional, or financial advisor before making any decisions regarding commercial leases or related matters.

Getting Ready to Lease

Leasing a commercial space is a long-term commitment and like anything long-term (a year or more) you want to give it some careful thought and consideration.  

Can you afford it?

Rent is expensive and long-term. Thus, we need to plan it out in a business plan or a financial forecast to make sure we know we can afford the rent and still make money after all our other expenses. At the planning stages, we can work with a “placeholder” or an anticipated amount that we expect the rent to cost and refine it as we move through the process.  In a nutshell, we need to know how many widgets or billable hours we will need to sell to break-even considering our rent and other operating expenses.

Many entrepreneurs skip this step because it isn’t as fun or exciting as building out a space and selling, but as the old adage goes “failing to plan is planning to fail”. So, please take a moment to meet with one of our SBDC consultants to review the numbers - after all it is free.

Building Your Team

Many small business owners don’t know that they can get the help of a commercial real estate agent/broker for free when they are looking for space to lease. In most cases, the landlord or the property owner pays the brokerage commission, which is split between the landlord’ listing agent and the tenant's agent.

For example, if you sign a 5-year lease at $5,000/month, the total lease value is $300,000. A 4% commission would be $12,000, usually split between the landlord’s broker and your “tenant rep” broker. So having an agent doesn’t make the deal more expensive for you — it just ensures someone is advocating for your interests.

That said, choosing the right broker can make all the difference in your leasing experience. Start by looking for a broker who specializes in the type of space you need — retail, office, or industrial — and who regularly works with small businesses. Ask other local business owners for referrals, check with your local chamber of commerce and check online reviews. Meet with at least two or three brokers to compare their approach, market knowledge, and communication style. The right broker should listen to your goals, explain your options clearly, and act as your advocate in negotiations, not just try to close a deal quickly.

Aside from a broker, you’ll want to work with the city because zoning laws, permits, and use restrictions can make or break your lease. Always check with the city planning department before signing — you don’t want to discover after the fact that your business type isn’t permitted or there are other issues that would prevent you from opening. Typically, there are city staff members with the title of “Community & Economic Development” that can provide key insights into not only the property you may be considering, but also future city developments and/or the history of the unit that will be useful to you as a business owner. These are the folks who can tell you where the “bodies are buried” if you are nice to them. So be nice!

Lastly, you’ll want to have a general contractor that is specialized in commercial tenant improvement projects. This is because once you find a space it will likely require some tenant improvements (also referred to as “TI” or leaseholder improvements) and you’ll need to cost this out by doing job walk of the unit with a contractor to see how much it’s going to cost to get the space ready to operate the business. 

Searching for the Right Space

Need-to-Have’s & Nice-to-Have’s

Before we move into searching for space we first need to sit down and think about our business and develop a list of need-to-have’s and nice-to-have’s. This will be essential to not only refine our search, but it also shows a broker that we’re serious and it can also help us evaluate our options. For example, a need-to-have might be a certain square footage for operations, storage and customer areas, whereas a nice-to-have might be green space or outdoor seating if it’s not critical to your operation.  

Restaurants often plan their space based on a table-turn model. For example, if a restaurant averages $25 per customer and seats 50 guests at a time, a full seating generates about $1,250 in sales. If the restaurant can turn those tables three times in an evening, total revenue for that day is $3,750. This is why the number of tables, seating layout, and customer flow are critical when evaluating whether a space can realistically support your revenue goals.  

I often tell clients that they better love the space because they are going to be spending so much time there (in their business) that if they don’t love it, it will be difficult to want to spend the time there that it will take to make your business successful. Look for that “oooo…oh yeah” feeling.

Research Tools

Sites like LoopNet, Crexi, and CoStar can help you see what’s out there, but don’t rely only on them. Many great spaces never hit the open market — another reason a broker is valuable.  
Setting up a free account on these listing platforms allows you to save your search criteria and turning on notifications, gives you instant alerts when new properties hit the market that match your needs—helping you stay ahead of the competition. These platforms also let you track saved listings, compare spaces side by side, and access additional details like lease terms and broker contacts, making the search process more efficient and organized.  

In terms of timing, most small businesses underestimate how long it takes to secure the right location. On average, expect 3–6 months just to search and negotiate a lease. If you need a specialized build-out (like a restaurant kitchen or fitness studio), the process can stretch to 9–12+ months once city permits and construction are factored in. To avoid last-minute stress, begin your search at least a year before you need to move in.

Property Types

Not all centers are created equal. Understand the differences between strip centers, lifestyle centers, malls, and stand-alone retail. Each attracts different customers and comes with different costs and responsibilities.

Big Box Centers

These retail hubs are anchored by one or more large-format stores such as Walmart, Target, or Home Depot. They attract value-driven, convenience-oriented shoppers who prefer one-stop shopping for essentials and home goods. Costs often include higher common area maintenance (CAM) fees due to large parking lots and shared infrastructure, and tenants may be required to comply with stricter signage and façade guidelines to align with the anchor tenant’s brand standards.

Regional Malls

Enclosed malls with national department stores or fashion anchors, regional malls pull a wide demographic of customers seeking a mix of shopping, dining, and entertainment. They often generate strong foot traffic but come with high rent and marketing contributions, as well as strict operating hours and tenant mix restrictions enforced by mall management. These centers also require tenants to invest heavily in buildout and store design to meet aesthetic requirements.

Lifestyle Centers

Open-air developments featuring a curated mix of higher-end retail, dining, fitness, and entertainment, lifestyle centers attract affluent, experience-driven customers who value ambiance and brand mix as much as the products themselves. Tenants often face higher buildout costs, stricter design guidelines, and premium rents to match the upscale positioning. These centers also place greater emphasis on events, landscaping, and amenities, which tenants indirectly support through elevated CAM fees.

Neighborhood Centers

Typically anchored by a grocery store or pharmacy, these centers attract local residents who shop frequently and prioritize convenience. Costs tend to be lower than malls or lifestyle centers, but tenants may face responsibilities like maintaining consistent hours, contributing to parking lot upkeep, and adhering to co-tenancy clauses tied to the anchor’s performance. These centers offer steady, repeat traffic but rely heavily on the success of the anchor tenant.

Understanding the Lease

Key Lease Structures & Clauses

The most important thing you can do before you sign a lease is read it. Many people are intimidated by lengthy documents and business jargon, but grab a cup of coffee and give it a read through and jot down or highlight sections that you’re not sure about. For the sections you don’t quite understand, be sure to ask for clarification and use AI tools like ChatGPT to help break things down in a manner that is easier to understand. Just be sure not to enter into ChatGPT any confidential information. One of my favorite things to do is take a complex concept or paragraph full of business jargon and ask ChatGPT to explain it to me like I’m five years old. You’d be surprised how well it does this. 

Common Types of Leases

There are four common types of commercial leases; a gross lease (full-service), a net lease, a modified gross lease and a percentage lease. The primary difference between these types is the allocation of operating expenses between the landlord and tenant. Here is a breakdown of the common types;

Gross Lease (Full-Service Lease)

The tenant pays a single, fixed rent amount, and the landlord is responsible for paying all or most of the operating expenses, such as property taxes, insurance, and maintenance.

Net Lease

A lease where the tenant pays a base rent plus some or all of the property's operating expenses.  There are three main types:

Single Net Lease:   Base rent + property taxes. 
Double Net Lease: Base rent + property taxes and insurance.
Triple Net Lease:    Base rent + property taxes, insurance, and maintenance costs. 

Modified Gross Lease

A hybrid between a gross lease and a net lease. The tenant pays a base rent plus a portion of the operating expenses, with the specific costs detailed and negotiated in the lease.

Percentage Lease

The tenant pays a base rent plus a percentage of their gross sales.

It is really important to define what is considered gross sales. For example, sales taxes and tips are sometimes included, but really aren't part of the business’s income.

Common Lease Clauses

An easy way to get comfortable with reviewing leases and feel more confident is by reviewing sample leases. Commercial leases come in a variety of shapes and sizes. Once you’ve had a chance to see a few - you’ll quickly see how some are very informal (short) and others are very formal and lengthy. Here are a few sample commercial lease agreements from eforms.com, rocketlawyer.com, lawdepot.com, etc..  

Nonetheless, there are some common clauses that you’ll encounter when reviewing a commercial lease. Let’s take a look at a few to get familiar with them and why they’re important;

These are just some of the most common clauses you’re likely to encounter in a commercial lease, but there may be other miscellaneous clauses and it would be important to have a licensed professional review your lease to ensure you’re okay with the agreement in its entirety. 

Negotiating Tips & Lease Checklist

At the end of the day, landlords will often present a pre-printed contract with language favoring their interests and it is up to the tenant to to negotiate the terms that they deem acceptable. 

Many small business owners view leasing with a fixed mindset, believing they have to accept the landlord’s terms exactly as written or walk away. The truth is, commercial leases are rarely one-size-fits-all. Landlords want long-term, stable tenants, and that gives you negotiating power. 

When negotiating, preparation and prioritization are essential. Let’s face it, out of all the places you’ve looked at (and there should be a lot) there will be a laundry list of things you’re going to want to negotiate. Once you have that list, you’ll need to sit down and prioritize the areas that are most important to you BEFORE you enter into any negotiations. And in order to have a healthy negotiation you need to have all the facts, or at least as much as you can realistically get, to be able to prioritize your list. 

So, whether it’s adjusting rent escalations, negotiating for tenant improvements, or securing renewal options, almost every lease term is open to discussion. Enter the process with the mindset that this is a partnership, not a handout — both sides benefit when the deal works for everyone.
