An office space lease is a legally binding contract between a landlord and a tenant for renting commercial real estate specifically designated for office use. People looking for an office to initiate businesses must consider signing an official space lease for convenience of the terms and conditions. Let us learn more about an office space lease and its important aspects below.
What Is an Office Space Lease?
If you're looking for an office for your business, you might consider signing an office space lease. These contracts typically run for about six months to a year. Most office space leases do not automatically renew, unless your lease has an automatic renewal clause, so business owners have a chance to change or renegotiate the agreement after the initial term of the lease. A tenant cannot vacate the property without breaking the lease. Generally, neither the landlord nor the tenant can change the terms of the agreement before the period of the lease expires unless both agree to a change.
Office space is usually somewhat less expensive per square foot than comparable retail space as office space comes with less risk; office leases are typically longer than retail leases but this depends on the specific agreement. Office space leases are good for businesses looking for things like:
- Cubicles
- Reception areas
- Public restrooms
- Space for offices
- Meeting rooms
- Kitchen or break rooms
- Parking facilities
- High-Speed internet
- HVAC services
- Venting and cleaning services
- Mail and package handling
- Common areas
Types of Office Spaces Leases
You'll find a few types of commercial office space leases:
-
Full Service Leases:
Also known as a gross lease, a full service lease is the simplest and most commonly used type of commercial office lease. This is typically the best kind of office space lease a tenant can sign. With a full service or gross lease, a landlord charges a tenant one gross lump sum payment each month. Depending on your agreement, full service leases may have the landlord responsible for paying for all expenses associated with a property, including:
- Janitorial services
- Property insurance
- Property taxes
- Maintenance and repairs
- Utilities
-
Net Leases
:
You may come across both double net leases and triple net leases. In general, a net lease includes a base amount of rent, plus a range of expenses related to the building. When you sign a net lease, a landlord will generally charge a significantly lower annual rent than a full lease but have added monthly expenses. However, the landlord may also include "usual costs" on a monthly basis, making the total amount you pay increase as "net" charges get added to the overall cost.
-
Double Net Leases:
Typically displayed in property leases with an "NN" designation, these leases have a tenant pay for utilities, janitorial expenses, and base rent, plus:
- A tenant's share of property insurance.
- A tenant's share of property taxes
-
Triple Net Leases:
Also known as "NNN" leases, this type of net lease charges a tenant base rent, janitorial expenses and utilities, and their share of:
- Common area maintenance fees, known as CAM fees.
- A tenant's share of property insurance.
- A tenant's share of property taxes
-
Double Net Leases:
Typically displayed in property leases with an "NN" designation, these leases have a tenant pay for utilities, janitorial expenses, and base rent, plus:
-
Modified Gross Leases
:
Rent on this type of lease is fixed, so you won't have any unexpected charges or hidden costs. However, you may have to pay rent plus your portion of:
- Common area maintenance fees
- Property insurance
- Property taxes
- Percentage Leases : These types of leases charge a tenant a base rent as well as a portion of the gross sales made from doing business in a building. Percentage leases are frequently used in retail malls.

How to Determine the Office Space Size You Need — And What That Will Cost
When you're searching for office space, one of the first things you'll need to decide is the size of the space you'll need to lease. You'll have to consider things like whether you'll receive clients at the office and how many staff members work for you when making this decision. One common estimate is to account for about 150 to 200 square feet of space for each employee.
Rental price is typically presented as a cost per square foot, calculated either per month or annually. You can calculate commercial rent by multiplying that price by the total number of square feet of office space.
If the rental price you see is for a year, you just need to divide the cost by 12 to figure out monthly base rent. However, different kinds of leases may have different forms of fees or inducements that come together to determine the total monthly outlay.
If you're signing an office space lease with the space priced by "rentable" square foot, the cost may turn out to be much higher than you expected. Landlords can include space that you cannot use to run your business in the lease. Here is an article that explains more about rentable square footage and other considerations when signing an office space lease.
Keep in mind that there's a difference between rentable square footage and useable square footage, and knowing those two figures will tell you the loss factors of any lease:
-
Rentable Square Footage:
This includes common areas that a landlord will allow you to use, for example:
- Elevators and stairs
- Lobbies
- Reception areas
- Usable Square Footage: This is the space that will be used exclusively by the staff of your office. Review your lease agreement to understand how these measurements are determined.
-
Loss Factor:
You can find this by calculating the percent difference between usable square footage and rentable square footage. Loss factor depends on:
- The physical configuration of an office.
- The method a landlord uses to measure the rentable areas.
- To a certain extent, the whims of a given landlord — a landlord may include things like air shafts that you are not really using in their calculation of rentable square footage
Factors that Impact Office Rent
Various factors will affect the amount your monthly office rent will be each month. These factors include:
- Building Quality: A building's age, building features, and included amenities impact rent.
- Location: The more convenient an office space is located, the more expensive it tends to be.
- Size: Before you commit to a space that's too big for your needs, think about what your business and its staff really require. However, it can get very expensive to move offices later on if you realize you have outgrown your space. If you're considering expanding your business down the road, you might look for an office space with flexibility that will be able to accommodate your business's growth in the future.
- Type of Lease: Whether your office space lease is a full service, net lease, modified gross lease, or percentage lease will affect your monthly costs.
- Market Demand: The demand for a specific commercial property can impact office rent. Rents may be higher in high-demand markets with limited spaces because the landlords will have more leverage. However, a few landlords may offer competitive office rent rates in areas with surplus commercial spaces.
- Lease Term : An office rent often depends on the property's specific lease term. Tenants may have to pay lower monthly rents if they have a longer lease term because of extended commitments. However, they may have to pay higher rents for shorter lease terms.
Classes of Office Buildings
When you sign an office space lease, you will want to understand the class of the building. In general, an office's class describes the quality of the structure as well as the amenities. Class is determined in comparison to other building classes. Here is an article that has more information about office space classes.
Three classes of office buildings exist. They are:
-
Class A:
Class A buildings are the highest-quality office buildings on the market. Characteristics of Class A buildings include:
- High-profile tenants
- Newest buildings
- Well-managed
Generally the best choices for businesses that need to impress clients, especially in industries such as:
- Design
- Finance
- Legal
- Marketing
-
Class B: While Class B buildings are usually older than most Class A buildings, some can still be restored to the quality of a Class A space. Other kinds of Class B structures are known as purpose-made Class B buildings. This latter type of Class B buildings is constructed to offer functional office space for a less expensive price.
-
Class C: Generally the least desirable office spaces, Class C buildings tend to be former Class A buildings that are around 10 to 15 years old or Class B buildings that are around 5 years old. Compared to Class A or B office spaces, Class C buildings may be:
- Older
- Found in less popular locations or neighborhoods
- In need of extensive maintenance or renovation
Final Thoughts on Office Space Leases
People looking to start new business ventures or working on the same always need commercial spaces. So, an office space lease is the perfect space for such individuals to carry on their work. It helps them sign a contract with the landlord after discussing the terms and conditions associated with property use. The rent decided for the same may vary depending on various factors. So, the individuals in charge must check the office rent before deciding to possess the property. Interested parties can also seek help from professional lawyers to negotiate a good deal with the landlord and sign a valid office space lease.

Can a landlord terminate an office space lease before the agreed-upon term ends?
I recently signed a lease agreement for office space for my small business, but due to unforeseen circumstances, I may need to relocate sooner than anticipated. I want to know if the landlord has the right to terminate the lease before the agreed-upon term ends, and if so, what are the potential consequences for me as the tenant? I am concerned about any financial penalties or obligations that may arise from terminating the lease early.
Damien B.
A landlord could agree to terminate the lease if a tenant requests it or can modify a lease to allow for an option for a tenant to vacate the premises at an earlier date. If a tenant wants to vacate the premises on an earlier date than the lease end date, either the landlord would have to agree to the earlier termination date or the tenant could be found in breach of contract. If you are considering early termination, it's advisable to communicate with the landlord to explore possible solutions, such as subleasing, assigning the lease, or negotiating a modification to the lease agreement. Feel free to reach out if you have other questions about this.

Can a landlord increase rent during the term of an office space lease?
I recently signed a lease for office space for my small business, and it includes a fixed rental rate for the entire term of the lease. However, I've heard rumors that the landlord has been increasing rent for other tenants in the same building, and I'm concerned that they might try to do the same with my lease. I want to know if it is legally permissible for the landlord to increase the rent during the term of my office space lease, or if I am protected by the terms of the lease agreement.
Ricardo A.
No Mid-Term Rent Hikes in a Fixed-Term Lease: In Texas, a landlord cannot increase the rent in the middle of a fixed-term office lease unless the lease agreement itself grants that right. A lease is a binding contract for the agreed term—typically one year or multiple years in a commercial setting—and both parties are locked into the agreed rent amount for that term. Texas law (and general contract principles) provides that neither the landlord nor the tenant can unilaterally change lease terms during the lease period without mutual consent. This means that if you have, say, a 3-year office lease at \$X/month, the landlord cannot suddenly demand \$X+100 in the second year unless the contract explicitly allows a mid-term increase. As the Texas State Law Library and tenant advocacy guides note, a written lease lasting a set time means the rent won’t change during that period “unless the lease gives the landlord the right to do so.” Any attempted rent increase not supported by the lease would violate the contract. Lease Agreement Controls Rent Adjustments: It’s crucial to check the lease document for any rent adjustment clauses. Some commercial leases include built-in escalation provisions—for example, an annual increase (e.g. 3% per year), or rent indexed to inflation, or increases in property taxes or operating expenses passed through to the tenant. If the lease contains such a clause, then the landlord can raise the rent according to that agreed formula or schedule, because the tenant consented to those terms when signing. In that case, it’s not a unilateral change but rather executing the contract. However, if the lease is silent on rent increases, the landlord must honor the fixed rent for the entire term. They cannot impose a new rent or add fees during the lease term without the tenant’s agreement. Any change in terms mid-lease requires both parties’ consent (usually documented in a written lease amendment) to be enforceable. No Statutory Rent Control – But Contract Must Be Honored: Texas has no statewide rent control, meaning there’s no law capping how much rent can increase between leases or in a renewal. Landlords are generally free to set or raise rent amounts when a new lease term begins. But this freedom does not allow breaking an existing lease. Even though Texas law doesn’t limit the amount of an increase, it does require that landlords abide by the lease during its term. In effect, the landlord must wait until the current lease expires before charging a higher rent (unless, again, the lease itself built in a mid-term increase). When the term is up, the landlord can propose a higher rent for the renewal or for a new tenant. During the term, the tenant is protected by the contract. In a recent example, a Texas news report highlighted that a landlord’s attempt to add a new fee mid-lease was improper, citing the rule that a lease can’t be changed in the middle of its term without agreement. Both parties are entitled to the benefit of their bargain for the full lease period. Month-to-Month or Short-Term Tenancies: The situation is different if the office space is on a month-to-month lease (which is less common for commercial leases but possible in some flexible office arrangements or holdover situations). In a month-to-month tenancy, the “term” is essentially one rental period at a time. Texas law allows a landlord to increase rent for the next period as long as they give proper advance notice (typically one rental period’s notice). For example, if an office is rented month-to-month, a landlord could notify the tenant that rent will go up starting next month (with at least 30 days’ notice if rent is paid monthly). The tenant then can choose to accept the new rent or terminate the tenancy before the higher rent takes effect. But even in this scenario, the landlord cannot raise the rent instantly or retroactively—any increase can only apply to future rental periods after notice. During any paid-for month, the agreed rent stays in effect. Enforcement and Remedies: If a commercial landlord were to attempt a rent increase mid-lease contrary to the contract, the tenant can refuse to pay the unauthorized increase and point to the lease terms. The landlord cannot legally evict the tenant for non-payment of an unagreed rent hike during the lease term (that would itself be a breach of the lease by the landlord). Section 91.004 of the Texas Property Code even states that if a landlord fails to comply with a lease, the landlord is liable for any resulting damages. In practice, most landlords will abide by the lease or negotiate with the tenant if changes are needed (for example, both might agree to a modest increase or other adjustment in writing). Tenants should keep records of the signed lease and any communications. If a dispute arises, the clear language that “a lease cannot be changed in the middle of the lease term unless both parties agree” will be the guiding rule under Texas law. Conclusion: For a typical commercial office lease in Texas, the rent is locked in for the duration of the lease term. A landlord may not increase rent mid-term unless the lease contract explicitly permits that change. The tenant has the right to rely on the agreed rate through the lease period. Only at the end of the term (or in a month-to-month scenario with proper notice) can the landlord impose a rent increase. In sum, the lease agreement’s terms and Texas contract law protect tenants from surprise rent hikes during the agreed term. Any deviation requires the tenant’s consent or a contractual clause—without that, a mid-term rent increase is not enforceable. Sources: -Trient Partners Ltd. v. Viacom Inc. (5th Cir. 1996)—discussing Texas law on contracts of indefinite duration being terminable at will. -Lazy M Ranch, Ltd. v. TXI Operations, LP**, 978 S.W. 2d 678 (Tex. App.–Austin 1998)—Texas case (cited in Driver Pipeline Co. v.
