What percentage of public accommodations must be accessible according to the ADA?

The Americans with Disabilities Act (ADA) mandates that all new constructions of public accommodations must be accessible, ensuring that individuals with disabilities have equal access to facilities. This comprehensive requirement means that there are no exceptions for a percentage of the construction; rather, every new public facility must meet specified accessibility standards. This approach emphasizes inclusivity and aims to eliminate barriers that could exclude individuals with disabilities from public spaces.

The other options imply a lesser degree of accessibility or percentages that do not align with the ADA's requirements. The law does not establish a percentage of existing facilities that need to be made accessible, nor does it suggest that only a portion of new constructions need to comply with accessibility standards. Instead, the focus is on complete compliance to provide full access to everyone regardless of their abilities.
