According to ADA regulations, private businesses are required to make their facilities accessible to the public except when?

The correct answer is that private businesses are required to make their facilities accessible to the public unless doing so would financially harm the business. This principle stems from the guidelines set by the Americans with Disabilities Act (ADA), which aims to ensure that individuals with disabilities have equal access to public accommodations and services.

In assessing compliance with the ADA, businesses must consider the financial impact of making modifications. If accessibility changes would impose significant financial hardship, the ADA recognizes that these businesses might be exempt from certain requirements. However, this does not mean that businesses can simply avoid making structural changes; they are often expected to explore alternative solutions that can provide accessibility without causing undue financial strain.

The other provided options—time consumption, inconvenience, and costs—do not serve as valid excuses for noncompliance under the ADA. These factors, while potentially challenging for businesses, do not meet the criteria established by the Act to justify a lack of accessibility. Thus, financial harm is the critical factor that can provide an exception to the ADA's requirements, making option B the correct choice.
