The property transaction closes next month. The lender wants updated paperwork on the data center building before approving the loan, and the buyer’s team needs to figure out whether the building actually works as well as the seller claims.
A standard building inspection would not answer that question. Data centers house rows of powerful computers (called servers) that store and move enormous amounts of digital information. Keeping those servers running around the clock typically takes far more electricity, far more cooling, and far stronger floors than a typical office or warehouse. Those differences mean a data center may require a more specialized evaluation than a standard property condition assessment provides.
This article explains what data centers are, how they differ from other commercial buildings, and what a condition assessment for these facilities typically covers.
Key takeaways: what a data center condition assessment covers
If your team is buying, selling, or refinancing a data center property – whether an enterprise-owned facility or a colocation building – a standard building inspection may not be enough. These assessments focus on the specialized power, cooling, and structural systems that keep data centers running.
What the assessment examines
- Power, cooling, structure, and the building exterior are evaluated together as one connected system
- Testing records and maintenance logs show whether backup systems have been verified
- The assessment can help confirm whether the building performs at the level described in deal paperwork
When your team may need one
- Before a property sale, refinancing, or insurance renewal requiring updated condition documentation
- When cooling, power, or the roof and walls show signs of change
- When government inspection deadlines or lease terms create compliance requirements

What is a data center?
A data center is a building designed to house computer servers and networking equipment. These servers store, process, and send digital information powering everything from email and online banking to streaming video and business software.
The building is expected to provide constant electricity, precise cooling, and protection from threats like water, dust, and extreme temperatures. Data centers range from a single room inside a larger building to massive standalone facilities, but regardless of size, the building and its systems are expected to work together reliably every day of the year.
Growing reliance on cloud computing and digital record-keeping has made data centers one of the fastest-growing categories of commercial real estate – from colocation facilities that house multiple tenants’ equipment to hyperscale campuses operated by major cloud providers. The National Telecommunications and Information Administration (NTIA) reports that more than 5,000 data centers operate in the United States, with demand projected to grow roughly 9% per year through 2030.
How data center buildings differ from other commercial buildings
Data centers operate on a completely different scale than office buildings, retail stores, or warehouses. The differences show up in three areas.
Electricity
Data centers are among the most power-hungry building types. The U.S. Department of Energy (DOE) reports that these facilities use 10 to 50 times the energy per floor area of a typical office building. That demand typically calls for larger backup generators, heavier-duty wiring, and automatic switches that move the building from regular to backup power within seconds.
All of that electrical equipment, along with the servers it supports, also adds up to a great deal of physical weight.
Weight
A fully loaded server rack (a tall metal frame holding stacked computer equipment) can weigh anywhere from 1,200 to several thousand pounds. That places far more weight on the floor than a typical commercial building is designed to carry. Most data centers are built with extra-strong concrete foundations and raised floor systems, and panels set above the main floor to create space for cables and airflow.
All of that equipment running at full power produces a great deal of heat that the building is expected to handle around the clock.
Heat
Servers produce a tremendous amount of heat. A densely loaded server cabinet can generate 10 kilowatts or more of heat, requiring dedicated cooling infrastructure to help prevent equipment failure. Cooling units keep temperatures within a very tight range, often within a few degrees of a target setting.
The moisture level in the air is also tightly controlled. Too much moisture may cause water to form on electronics, while too little may create static electricity that damages parts. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) publishes the temperature and humidity guidelines that data center operators widely follow, covering acceptable ranges for inlet air temperature and relative humidity at server equipment.
These demands on power, weight, and temperature are what make data center condition assessments different from standard building evaluations.
What is a data center condition assessment?
A data center condition assessment is a technical evaluation of the power, cooling, structural, and building envelope systems that keep a data center operational. Unlike a standard property inspection, which covers the roof, plumbing, and general wiring, a data center assessment examines the specialized infrastructure that keeps servers running: backup power systems, redundant cooling, uninterruptible power supplies, and floors engineered for extreme concentrated loads.
These assessments commonly come up during property sales, insurance renewals, or capital planning. The scope covers the same areas included in evaluations: structure, heating and cooling, electrical systems, and the roof and exterior walls.
What does a data center condition assessment typically examine?
Data center assessments generally cover four areas: power, cooling, the building’s structure and exterior, and past testing and maintenance records.
Power and electrical systems
Assessors follow the path electricity takes through the building: from the point where utility power enters, through large batteries that keep things running during short outages, through wiring panels that send power to rows of computer equipment, and out to backup generators that kick in during longer outages. Energy efficiency is also evaluated: data centers are benchmarked using power usage effectiveness (PUE), a ratio of total facility power to IT equipment power. The Uptime Institute’s annual surveys have found the global average PUE to be approximately 1.58, meaning a typical facility uses roughly 58% more energy than the servers alone require. An assessor can identify inefficiencies in power delivery and cooling systems that push PUE higher than necessary.
Assessors also look at the automatic switches that move the building between its main power source and backup power. A major focus is identifying single points of failure: components whose failure could take down the entire facility even when redundant backup systems are in place.
The cooling equipment is closely tied to the electrical systems because all of that computer equipment generates a great deal of heat.
Cooling equipment
Assessors check whether the specialized cooling units are working properly, whether backup cooling is ready to take over if the main system goes down, and whether cool air is reaching every area where servers are running. Energy use is also reviewed, since cooling is often the largest utility cost in a data center after the computer equipment itself.
Beyond the cooling equipment, the physical building is also expected to hold up under conditions far more demanding than a typical office or warehouse.
Building structure and exterior
Structural assessments check whether floors, foundations, and raised floor panels (elevated platforms with space underneath for cables and airflow) appear strong enough for current equipment and any heavier equipment planned for the future. The building envelope review, covering the roof, walls, windows, and waterproofing, looks for signs that water could be getting inside. Even a small amount of moisture may damage data center equipment worth millions of dollars.
The building’s physical condition tells part of the story. The facility’s paperwork tells the rest.
Testing records and maintenance history
Assessors typically review the building’s records to see whether its systems have been formally tested. This testing, sometimes called commissioning, can range from checking individual pieces of equipment to full integrated systems testing that simulates a power failure across multiple systems simultaneously. Missing or incomplete records may make it harder to confirm that backup systems will work when needed.
With these four areas in mind, the next question is when this level of evaluation is typically needed.
Which codes, rules, and equipment timelines may affect a data center?
Some rules that apply to data centers are legally required, while others are voluntary guidelines that become binding only when written into a contract or lease.
Legally required codes
National Fire Protection Association (NFPA) codes cover fire safety and electrical wiring safety for buildings that house computer equipment. These codes become law when a city or county officially adopts them, and not every location has adopted the same version. The Occupational Safety and Health Administration (OSHA) sets workplace safety rules that generally apply to data centers as well.
Alongside mandatory codes, industry guidelines may also apply depending on the terms of a lease, loan, or insurance policy.
Voluntary guidelines
Industry organizations publish recommended guidelines for how data centers should be built and run. These are not law, but lenders, insurance companies, or tenants may insist on following them as a condition of doing business. Some cities and counties have also started writing local rules covering electricity usage, water used for cooling, and noise from generators. Because local rules differ widely, confirming which ones apply to a specific property is an important early step.
Equipment replacement timelines
Beyond codes and guidelines, how long equipment lasts also affects when assessments are needed. Data center equipment typically wears out faster than similar equipment in an ordinary office building. Backup batteries may need replacement sooner than other electrical parts. Cooling equipment tends to work harder and use more energy as it ages. Generators typically need regular testing to stay reliable.
These shorter lifespans mean capital expenditure (CapEx) planning for data centers may not match the assumptions used for standard commercial buildings. Scheduling evaluations around equipment age – such as when a cooling unit reaches the midpoint of its expected life or a UPS battery bank approaches its replacement window – may reveal wear earlier than waiting for a set calendar date.
Protecting data center investments through proactive assessment
Data centers place extreme demands on the buildings that house them. Condition assessments designed for these facilities may help owners and property managers make better-informed decisions about repairs, rule compliance, and long-term spending.
Because the codes and guidelines that apply differ by location, and because voluntary standards can become binding through lease or loan terms, confirming which rules apply is a practical first step in any property deal or planning cycle – whether the facility is an enterprise-owned building, a colocation facility serving multiple tenants, or a hyperscale campus.

Frequently asked questions
How does a data center condition assessment differ from a standard building inspection?
A data center assessment looks at specialized systems that standard building inspections typically do not cover in depth, including backup power, specialized cooling equipment, and floors built to carry extremely heavy loads. The evaluation also checks whether these systems work together reliably as a connected unit.
Are data center industry codes legally required?
Some codes become legally required when adopted by local governments, and adoption varies by location. Most industry guidelines are voluntary unless a contract, lease, or local rule specifically requires them.
How often should data center buildings be professionally assessed?
Timing depends on several factors: equipment age, upcoming lease expirations or loan renewals, property transactions, and insurance requirements. As a general guide, a full condition assessment is commonly conducted every three to five years, or sooner when major equipment approaches the midpoint of its expected service life, when a transaction is pending, or when operational changes are under consideration.
