An ADA accessible unit is a wheelchair-sized restroom with grab bars and a ground-level floor. Public buildings, schools, health facilities and sites with public access usually carry one; it costs $169 to $250 per 28 days with weekly service in Florida (vendor-published, 2026).
Count the ADA unit toward the OSHA total. On a 40-person site: 3 standard + 1 ADA + 1 handwash.
OSHA sets the count, not the type. The ADA requirement comes from the owner, the funding or public access.
About $30 to $40 more per 28 days than a standard unit in Florida.
