The structural stability of parking garages is being analyzed more closely by NYC DOB in response to the most recent collapse in lower Manhattan during April 2023, killing one person and injuring five others. Dozens of garages with potential hazards were identified and some were ordered closed totally or partially until their structural defects could be repaired.
Coops and condos sometimes have parking garages as a part of their buildings. The coop could own the garage which is a part of its building and be responsible for the structural integrity of the garage. A condo could have the garage as a condo unit and should evaluate whether the condo is responsible for the structure or whether the impacted parts of the garage are limited common element or a part of the garage unit and the responsibility of the garage unit owner. The condo board may be obligated to compel the garage unit owner to make the repair irrespective of who is responsible for the cost of the work.
These could be life, health and safety issues which boards should be aware of and take action that is in the best interest of their association.
