GREB Section 501.4 is amended to read as follows:
501.4 Accessibility requirements. The following accessibility requirements shall apply to a change in occupancy as defined in chapter 3.
501.4.1 Entire building. When a change in occupancy of a building places the building in a different division of the same occupancy group or in a different occupancy group, the building shall have all of the following accessible features:
1. At least one accessible building entrance.
2. At least one accessible interior route from an accessible building entrance to primary function areas. Vertical conveyance devices used as part of an accessible route shall be installed in compliance with the Minnesota Accessibility Code and the Minnesota Elevator Code.
3. Accessible parking, where parking is provided.
4. At least one exterior accessible route from accessible parking to an accessible building entrance. If no parking is provided, at least one exterior accessible route within the boundary of the site to an accessible building entrance.
5. At least one accessible unisex or male and female toilet room for every 3 levels of the building.
No requirement for change in occupancy of a building shall impose a requirement for greater accessibility than that which would be required by the Minnesota Accessibility Code for new construction. However, if compliance with any of the requirements of this section is technically infeasible, the change in occupancy shall not be permitted.
501.4.2 Portion of building. When a change in occupancy of a portion of a building places the portion of the building in a different division of the same occupancy group or in a different occupancy group, all of the following accessible features shall be provided:
1. At least one accessible building entrance.
2. At least one accessible interior route from an accessible building entrance to the portion of the building undergoing the change in occupancy. In multistory buildings where the portion of the building undergoing the change in occupancy is located above or below the level of access and the number of occupants of the new occupancy exceeds 30 occupants, an accessible vertical route shall be provided.
Exception: Regardless of occupant load, an accessible vertical route shall be provided in multistory buildings where the new occupancy is a public area of retail sales, medical care facility, transportation facility, or government entity.
Vertical conveyance devices used as part of an accessible route shall be installed in compliance with the Minnesota Accessibility Code and the Minnesota Elevator Code.
3. Accessible parking, where parking is provided.
4. At least one exterior accessible route from accessible parking to an accessible building entrance. If no parking is provided, at least one exterior accessible route within the boundary of the site to an accessible building entrance.
No requirement for change in occupancy shall impose a requirement for greater accessibility than that which would be required by the Minnesota Accessibility Code for new construction. However, if compliance with any of the requirements of this section is technically infeasible, the change in occupancy shall not be permitted.
GREB Section 501.5 is amended by modifying the reference to "Tables 5-A through 5-E" to read "Tables 5-A through 5-D."
