I am also in PA and have talked with the PA Department of Labor and Industries Accessibility Advisory Board concerning the IBC 2009, 3411.4 issues.
Example #1: If a tenant space in strip mall changes occupancy classification, and is only separated from adjacent spaces by fire barriers, this building is not a “complete change in occupancy to an entire building”.
• It would be a partial change in occupancy.
• Any new work needs to meet current code for accessibility (3411.6)
• The 20% Rule kicks in (3411.7):
IBC 3411.4 Change of occupancy. Existing buildings that undergo a change of group or occupancy shall comply with this section.
IBC 3411.4.1 Partial change in occupancy. Where a portion of the building is changed to a new occupancy classification, any alterations shall comply with Sections 3411.6, 3411.7 and 3411.8.
IBC 2009, 3411.7 Alterations affecting an area containing a primary function. Where an alteration affects the accessibility to, or contains an area of primary function, the route to the primary function area shall be accessible. The accessible route to the primary function area shall include toilet facilities or drinking fountains serving the area of primary function.
Exceptions:
1. The costs of providing the accessible route are not required to exceed 20 percent of the costs of the alterations affecting the area of primary function.
Example #2: If a tenant space in strip mall changes occupancy classification, and is separated from adjacent spaces by fire walls, this building is a “complete change in occupancy” since fire walls create separate buildings.
• This would be a complete change of occupancy to an entire building (between firewalls)
• Therefore items 1 thru 6 of 3411.4.2 need to be done regardless of cost
• Also, there is a requirement to upgrade accessible routes to primary function areas and toilet rooms and water fountains, 20% rule since 3411.4.2 refers back to 3411.4.1 and that section take the 20% rule into consideration
• PA L&I had stated in conversation that in applying the 6 required items from 3411.4.2, these costs may be applied toward the 20%
IBC 3411.4.2 Complete change of occupancy. Where an entire building undergoes a change of occupancy, it shall comply with Section 3411.4.1 and shall have all of the following accessible features:
1. At least one accessible building entrance.
2. At least one accessible route from an accessible building entrance to primary function areas.
3. Signage complying with Section 1110.
4. Accessible parking, where parking is being provided.
5. At least one accessible passenger loading zone, when loading zones are provided.
6. At least one accessible route connecting accessible parking and accessible passenger loading zones to an accessible entrance.
