CID Colony, Rahatani, is a residential area located in the Pimpri-Chinchwad (PCMC) area of Pune. It's primarily known as a middle-class residential zone with a mix of independent houses, apartments, and chawls. It's relatively well-established and has seen decent development over the years. The name "CID Colony" suggests it was initially developed for employees of the Criminal Investigation Department (CID), although now it's open to all residents.
