How the Cleanliness of a Workspace Affects Employee Performance — What the Research Says
There is a conversation happening in boardrooms, HR departments, and commercial real estate circles that did not exist ten years ago. It is not about compensation packages, remote work policies, or office design trends. It is about cleanliness — and specifically, about what the physical condition of a workspace does to the people who spend their working lives inside it.
The research on this topic is more substantial than most property owners and facility managers realize. And the conclusions are more consequential than most would expect.
A dirty, cluttered, or poorly maintained workspace does not just look bad. It affects how employees think, how they feel, how they interact with each other, and ultimately how they perform. The connection between the physical environment and human performance is not a soft HR concern. It is a documented operational reality with measurable financial implications for every commercial property that houses a workforce.
This post covers what the research actually says — and what it means for commercial property owners, facility managers, and the organizations that depend on their buildings every day.
The Research Foundation: Why Environment Shapes Performance
The relationship between physical environment and human performance has been studied across multiple disciplines — organizational psychology, environmental science, public health, and behavioral economics. The findings across all of these fields point in the same direction.
People perform better in clean, well-maintained environments. They perform worse in dirty, cluttered, or neglected ones. And the mechanisms through which the environment affects performance are more varied and more powerful than most people intuitively assume.
The field of environmental psychology has produced decades of research demonstrating that the condition of a person's environment directly influences their cognitive function, emotional state, stress levels, and social behavior. These effects are not marginal. They are significant enough to show up in productivity metrics, absenteeism rates, error frequencies, and employee retention data.
Understanding these mechanisms is the starting point for understanding why facility management is not just a property maintenance function. It is a workforce performance function.
How a Dirty Workspace Affects the Brain
Cognitive Load and Mental Clarity
One of the most well-documented effects of a cluttered or dirty environment is increased cognitive load. Cognitive load refers to the amount of mental processing power being used at any given moment. When the brain is processing visual disorder, clutter on surfaces, dirt on floors, disorganized spaces, visible maintenance failures, it is consuming mental resources that would otherwise be available for focused work.
Research from Princeton University's Neuroscience Institute found that physical clutter in a person's environment competes for their attention, reducing the brain's ability to focus and increasing the cognitive effort required to complete tasks. The study used neuroimaging to demonstrate that visual disorder actively limits the brain's processing capacity.
For employees working in a dirty or cluttered commercial environment, this means a measurable reduction in the mental bandwidth available for their actual work. They are not consciously thinking about the dirty floor or the stained ceiling tiles, but their brains are processing that environmental information nonetheless, and that processing comes at a cost to their cognitive performance.
Stress and Cortisol
The connection between environmental disorder and stress is equally well established. Research published in the journal Personality and Social Psychology Bulletin found that people who described their environments as cluttered or full of unfinished projects showed higher levels of cortisol throughout the day compared to people who described their spaces as restful and restorative.
While this research focused on home environments, the mechanisms are the same in commercial settings. A workspace that is visibly dirty, poorly maintained, or cluttered communicates disorder to the brain, and the brain responds to perceived disorder with a stress response. Elevated cortisol over sustained periods is associated with reduced cognitive function, impaired decision-making, lowered immune function, and increased likelihood of burnout.
For employers, this means that a poorly maintained workspace is not just aesthetically unpleasant. It is actively generating a physiological stress response in their workforce every day, with all of the performance and health consequences that entails.
Decision Fatigue and Error Rates
There is a further cognitive consequence of working in a disordered environment that rarely gets discussed in facility management contexts: its contribution to decision fatigue.
Decision fatigue refers to the deterioration in the quality of decisions made after a long session of decision-making. Research has consistently shown that the quality of decisions declines as the cognitive resources required to make them become depleted over the course of a day. Environmental disorder accelerates this depletion by consuming cognitive resources that would otherwise be available for decision-making tasks.
In practical terms, employees working in poorly maintained environments reach decision fatigue earlier in the day, make more errors in judgment, and demonstrate lower quality in complex cognitive tasks, not because they are less capable, but because their environment is consuming mental resources that should be available for their work.
How Cleanliness Affects Health—and What Health Costs Performance
The health dimension of workspace cleanliness is the most directly measurable link between facility management quality and employee performance. It is also the most financially significant.
Absenteeism and Illness Transmission
Commercial workplaces are high-transmission environments for infectious illness. Shared surfaces, door handles, elevator buttons, shared equipment, restroom fixtures, break room countertops, are touched by dozens or hundreds of people every day. Without regular, effective disinfection, these surfaces become vectors for the transmission of respiratory viruses, gastrointestinal pathogens, and other communicable illnesses.
The financial cost of illness-related absenteeism in commercial settings is substantial. The Centers for Disease Control and Prevention has estimated that productivity losses related to personal and family health problems cost employers in the United States approximately $1,685 per employee per year. Across a workforce of even modest size, this represents a significant operational cost, and a meaningful portion of it is directly attributable to workplace illness transmission that effective cleaning protocols would prevent.
Research consistently shows that workplaces with rigorous cleaning and disinfection programs, particularly programs that address high-touch surfaces multiple times per day rather than once during an overnight cleaning cycle, experience measurably lower rates of illness-related absenteeism than workplaces with lower cleaning standards.
Presenteeism: The Hidden Cost
Beyond absenteeism, the research points to an equally significant but less visible cost: presenteeism. Presenteeism refers to the phenomenon of employees being physically present at work but performing at reduced capacity due to illness or health-related impairment.
Studies on presenteeism consistently find that its cost to employers exceeds the cost of absenteeism. An employee who stays home sick costs the organization their output for that day. An employee who comes to work sick, or who is experiencing the early or late stages of an illness, costs the organization a portion of their output every hour they are there, and potentially spreads their illness to colleagues, multiplying the productivity loss across the team.
A workplace with high cleaning standards reduces both the transmission events that cause illness and the environmental conditions, poor air quality, accumulated dust and allergens, inadequate restroom hygiene, that exacerbate respiratory and immune conditions that drive presenteeism.
Indoor Air Quality and Cognitive Performance
The relationship between indoor air quality and cognitive performance deserves particular attention. Research published in the journal Environmental Health Perspectives found that workers in environments with high indoor air quality performed significantly better on cognitive function tests than workers in environments with poor indoor air quality.
The same research found that improving ventilation and reducing indoor pollutant levels produced measurable improvements in decision-making speed, information usage, and task performance. The cognitive improvements associated with better air quality were significant enough to affect the kind of complex cognitive work that drives organizational performance.
Facility management directly affects indoor air quality through HVAC maintenance, cleaning product selection, ventilation management, and the elimination of mold, dust, and allergen accumulation. A building that is maintained to a high standard is, among other things, a building with better air, and better air produces better cognitive performance from the people who breathe it.
How Cleanliness Affects Culture, Morale, and Retention
The performance effects of workspace cleanliness extend beyond individual cognition and health into the social and cultural dimensions of an organization. These effects are harder to measure directly but no less real in their consequences.
What a Dirty Workspace Communicates
Organizational psychologists have long recognized that physical environments communicate values and priorities to the people who inhabit them. A workspace that is consistently clean, well-maintained, and cared for communicates that the organization values its people and takes pride in its environment. A workspace that is dirty, neglected, or poorly maintained communicates the opposite.
Research on organizational culture consistently finds that employees derive meaningful information about how much their employer values them from the physical conditions of their workplace. A company that invests in a clean, well-maintained environment signals to its employees that their comfort, health, and working conditions matter. A company that allows its workplace to become dirty or neglected signals that these things do not matter enough to address.
This signal has measurable consequences for employee morale, engagement, and retention. Employees who feel that their employer does not value their working conditions are less likely to feel valued as individuals, and less likely to remain with the organization.
The Broken Windows Effect in Commercial Environments
The broken windows theory, originally developed in the context of urban crime reduction, has been extensively studied in organizational contexts. The core principle is that visible signs of disorder and neglect in an environment create a permissive context for further disorder and lower standards of behavior.
In commercial workplace settings, research has found that employees working in visibly neglected or poorly maintained environments tend to demonstrate lower standards of care for shared spaces, more casual attitudes toward deadlines and quality standards, and reduced organizational citizenship behavior. The physical environment sets the standard, and when that standard is low, individual behavior tends to follow.
Conversely, workplaces that are consistently clean and well-maintained tend to generate higher standards of personal and professional behavior from the people who work in them. The environment communicates what is expected, and people generally rise to meet the standard their environment sets.
Talent Attraction and Retention
In a competitive talent market, the physical condition of a workplace is a factor in both attracting and retaining employees. Research on workplace preferences consistently shows that cleanliness and environmental quality rank among the top factors employees consider when evaluating a workplace.
A survey by the cleaning industry association ISSA found that the majority of office workers would consider leaving a job if the workplace was consistently dirty or poorly maintained. A significant proportion reported that the cleanliness of a prospective employer's office influenced their decision to accept a job offer.
For commercial property owners and the organizations that lease their buildings, this research has a direct implication: the cleanliness of the physical environment is a talent strategy variable, not just a maintenance variable. A building that is consistently maintained to a high standard supports the tenant organizations' ability to attract and retain the people they need to perform.
What This Means for Commercial Property Owners and Facility Managers
The body of research reviewed in this post leads to a straightforward conclusion: the cleanliness of a commercial workspace is not a cosmetic concern. It is a performance variable, one that affects cognitive function, health outcomes, stress levels, morale, culture, and talent retention in measurable ways.
For commercial property owners, this means that the quality of facility management in your building directly affects the performance of every organization that operates within it. Tenants whose employees work in a clean, well-maintained environment perform better, experience lower absenteeism, and report higher workplace satisfaction. Tenants whose employees work in a poorly maintained environment experience the opposite, and eventually, they look for a better building.
For facility managers, this research reframes the purpose of the work. Professional facility management is not about keeping a building looking presentable. It is about creating and maintaining an environment in which people can do their best work. Every cleaning protocol, every preventive maintenance schedule, every documented quality assurance process is, at its foundation, a contribution to the cognitive and physical wellbeing of the people in the building.
For the organizations that occupy commercial buildings, the implication is equally direct: the facility management standard of your workplace is a leadership decision with workforce performance consequences. Accepting a lower standard because it appears to cost less is a false economy, one that generates real costs in productivity, health, morale, and retention that dwarf any savings on the facility management budget.
The research is clear. The environment shapes the performance. And the performance of the environment is the responsibility of the people who manage it.
Why This Matters for Northeast Ohio Commercial Properties
For commercial properties across Northeast Ohio, office buildings, school campuses, healthcare facilities, industrial spaces, and mixed-use developments, the connection between facility management quality and workforce performance is a competitive consideration.
In a regional economy where businesses are competing for talent, clients, and market position, the physical environment of a commercial building is not peripheral to organizational success. It is part of the foundation on which that success is built.
Immaculate Management Group has been maintaining commercial environments across Northeast Ohio since 2011 with the understanding that what we do is not just about cleanliness. It is about the people inside the building, their health, their focus, their sense of being in a place that is cared for and worth caring about in return.
That understanding is what separates a facility management partner from a cleaning vendor. And it is what drives every decision we make about how we maintain the buildings and spaces our clients trust us with.
