Reasonable accommodation is any modification or adjustment to a job, the work environment, or the way things are usually done that enables a qualified individual with a disability to enjoy equal employment opportunities. Under the Americans with Disabilities Act (ADA), covered employers are legally required to provide these accommodations unless it causes "undue hardship"—a significant difficulty or expense. This guide breaks down what qualifies, the process for requesting accommodations, and the responsibilities of both parties.
The ADA defines a reasonable accommodation as a change that enables an employee with a disability to perform the essential functions of their job. These essential functions are the fundamental duties of the position. Accommodations are not about special treatment; they are about providing equal access. Common examples include, but are not limited to:

For example, while a large corporation may be expected to install an elevator or modify a break room, a small business with limited resources would likely not be required to undertake such a costly structural change. In such cases, the employer and employee should engage in an interactive process to brainstorm alternative, less costly solutions that still meet the employee's needs.
The process begins when an employee discloses a disability and requests an accommodation. This should be a collaborative dialogue. Employees should:
Employers should:
Based on our assessment experience, a positive and cooperative relationship between employer and employee is the most critical factor for a successful outcome.
Successfully integrating accommodations requires thoughtful execution to maintain workplace harmony. Open communication is essential. If an accommodation, such as a flexible schedule, is noticeable to other employees, it can be helpful for the employer to address it in a way that respects privacy—for instance, by stating that adjustments are made for various reasons to support all employees.
The goal is to ensure the employee with a disability is integrated into the team, not singled out. Documenting the agreed-upon accommodation and periodically reviewing its effectiveness is a standard best practice for human resources departments.
To summarize, the core principles are:
