As with any other change of use or remodeling project, the building code requires that new work (such as new restrooms) meets current accessibility standards AND requires spending up to 25% of the value of a project on improving the access to and within an establishment. This "25% rule" applies to changes of occupancy as well as remodeling projects. The code lists the order of priority for improvements:
2. an accessible entrance,
3. an accessible route to the altered area,
4. at least one accessible restroom for each sex or an additional single unisex restroom, etc.
