How Is a Data Center Lease Different From an Office Lease?

An AI company can end up negotiating both kinds of agreement in the same year, sometimes with the same executive signing each. The word lease appears in both conversations, which hides how different they are. An office lease is a real estate contract for a place where people work. A data center agreement, whether it is called a lease, a license or a master services agreement, is closer to a contract for infrastructure delivered in a building.

This guide explains the differences at a conceptual level so that a founder or operations lead knows which questions belong to which contract. We should say plainly where our own work sits: TAG represents tenants in office, flex and industrial space. Data center and colocation procurement is a separate specialty, and the details of those contracts should be reviewed by advisors and attorneys who work on them regularly.

In an office, the unit of account is floor area. Rent is quoted per rentable square foot, and the size of the suite is the main driver of the bill. Electricity is a secondary cost, often included in rent or billed on a submeter.

In a data center, the scarce resource is power, along with the cooling needed to remove the heat it becomes. Pricing therefore commonly follows the electrical capacity a customer reserves, with the energy actually consumed billed in addition or folded into the rate depending on the deal. The physical footprint, whether a cabinet, a cage or a private suite, is usually a consequence of the power commitment, not the starting point.

That reverses the logic of the negotiation. An office tenant asks how many people the space holds. A data center customer asks how much power it can draw, how densely, and how quickly more can be added. A growing company may also commit to a ramp, taking and paying for capacity in stages.

An office landlord's obligations are modest. The lease typically requires the landlord to provide building services such as heating and cooling during stated hours, elevators, cleaning and utilities, and to keep the structure and common systems in repair. If the power goes out or the air conditioning fails, the tenant's remedies are usually limited, and leases often say that interruptions do not excuse rent except in narrow, negotiated circumstances.

A data center agreement is built around the opposite expectation. The operator commits to service levels, commonly written as a service level agreement, covering matters such as the availability of power and the temperature and humidity of the environment. If the operator misses them, the contract normally provides a remedy, most often credits against fees, and sometimes a right to terminate after repeated or prolonged failures.

The practical difference is who carries the risk of downtime. In an office, the tenant largely carries it and plans around it. In a data center, the customer pays the operator to engineer that risk down and to stand behind the result. How far the remedies go, and what is excluded from them, is one of the most negotiated parts of the contract.

Several concepts in data center agreements have no real equivalent in an office lease.

• Cross-connects. A cross-connect is a physical cable linking your equipment to a carrier, a cloud provider or another customer inside the facility. They are ordered individually and typically carry their own recurring charges.
• Carrier access. Data centers market the range of network providers available inside the building. In an office, you ask which carriers serve the building and how they reach your suite through the risers.
• Remote hands. Because your staff may not be on site, operators offer technicians who will perform tasks on your equipment for a fee.
• Access and security procedures. Entry is tightly controlled, with identity checks and logged access. An office lease gives your employees general access and reserves the landlord's right to enter.
• Rules on equipment. The operator may set standards for how equipment is installed, powered and cooled, and may limit the density you can deploy in a given area.
• Continuous operation. A data center runs around the clock by design. An office building runs on business hours, with after-hours services available at extra cost.

The contracts also differ in what happens at the end. An office tenant returns the suite in a required condition. A data center customer removes its equipment and data on a defined schedule, and the agreement usually addresses what happens to equipment left behind.

Some topics appear in both contracts but with different stakes.

• Term and renewal. Both run for a fixed term with possible renewals. In a data center, renewal pricing and the right to keep the same capacity matter greatly, because moving live equipment is disruptive and costly.
• Expansion. An office tenant negotiates rights to adjacent space. A data center customer negotiates rights to additional power, which may or may not be physically next to its existing footprint.
• Price increases. Both typically include scheduled escalations. Data center agreements may also pass through changes in the cost of electricity.
• Transfers. Rights to assign the contract or let affiliates use the space matter in both, and they deserve attention before an acquisition or financing.
• Liability. Data center agreements usually cap the operator's liability and exclude certain kinds of damages. Understanding those limits is central to deciding how much redundancy you need of your own.

Most software-focused AI teams need an office lease and a cloud account, and never sign a data center agreement at all. Companies that own their hardware and run it at scale need a colocation or data center arrangement in addition to an office. Teams building physical products, such as robotics or devices, may need flex or light industrial space with stronger power and loading, which is still a real estate lease and not a data center contract.

• ✓Where does our heavy compute run today, and will that change during the next lease term?
• ✓Do we own, or plan to own, servers that must run continuously?
• ✓What equipment will physically sit in the office, and can an ordinary office building support it?
• ✓Who on our team owns the data center or cloud relationship, and who owns the office search?
• ✓Do the two timelines depend on each other, for example a lab in the office that needs low-latency links to our servers?
• ✓Have we engaged the right specialist for each contract?

We handle the office, flex and industrial side of that picture for technology companies, and we coordinate with a client's infrastructure team so the workplace lease supports whatever sits in the office without pretending to be something it is not.
