Date(s) of Assessment: September 1, 2023

The Office of the Environment assessed the areas and believed that the discoloration was primarily dust and possibly some grease from the fan motors. The Office of the Environment could not rule out the presence of mold.

The interior of the units were also assessed due to histroical issues with the sound liner. The sound liner for both units within the penthouse was intact and in good condition with no visible suspect mold growth.
