Areas that May Be Disputed



Electrical Rooms

May be considered C&S if they house central distribution equipment, but may also be considered tenant space if dedicated to a specific tenant.

Data/Telecommunications Rooms

Similar to electrical rooms, may be C&S or tenant space depending on their usage.

Janitorial Closets

Sometimes included in C&S since they serve the entire building, but may also be considered tenant space if they are dedicated to a specific floor or group of tenants.*

Storage Rooms: Usually considered tenant space, but if they are centrally located and shared by multiple tenants, they may be considered C&S.Ultimately, the exact definition of C&S can vary depending on the lease agreement and specific building characteristics. It is recommended to consult with legal counsel and industry professionals to clarify the scope of C&S areas in a particular project. Flag for review
