TED STA I T N E U S U.S. Access Board Technical Guide A D C R C A ESS BO Toilet Rooms This guide explains requirements in the ADA Standards for toilet rooms. Required Compliance [§213] Plumbing and building codes address the number and type of toilet rooms and toilet fixtures required for a facility. The ADA Standards, on the other hand, do not address the number of toilet rooms or fixtures required for a facility, but instead specify which ones must be accessible where provided. In new construction, access is required to all toilet rooms, including those for employees. However, where single user toilet rooms are clustered in one location, at least half for each use must comply (§213.2., Ex. 4). In the case of single user portable units, access is required to at least 5% at each cluster, excluding those on construction sites for construction personnel which are fully exempt (§213.2, Ex. 3, §203.2). Clustered Single User Toilet Rooms Clustered single user toilet rooms (2 minimum) are those that are next to, or close to, one another. No more than 50% for each use within a cluster must comply. Compliant toilet rooms and portable units must be labeled by the International Symbol of Accessibility unless all are accessible (§213.2, Ex. 3, §216.8).
