Apartment Investment and Management Co., or AIMCO, amended its complaints against Airbnb to include all apartment owners whose properties have been rented without Airbnb first obtaining permission.

The suits, in California and Florida state courts, allege that Airbnb is a short-term rental broker directly involved in business transactions, and as such disregards its own terms of service and violates the rights of property owners.

Additionally, AIMCO filed an amended complaint in its second lawsuit against Airbnb in Miami-Dade County, Fla., Circuit Court.
