Taarak Mehta Ka Ooltah Chashmah — Gokuldham Society is a residential society in Powder Galli, Goregaon, Mumbai. Seven families reside in Gokuldham society:
Jethalal Champaklal Gada, an electronics shop-owner from Kutch district, Gujarat, and his wife Daya, father Champaklal Jayantilal Gada and son Tipendra (Tappu),
the narrator, Taarak Mehta, a column-writer and his wife Anjali, who are also from Gujarat,
the society secretary, Aatmaram Tukaram Bhide, a home tutor from Ratnagiri, Maharashtra, his wife Madhavi and daughter Sonalika (Sonu),
Dr. Hansraj Hathi, the resident doctor from Uttar Pradesh, his wife Komal and son Gulabkumar (Goli),
Roshan Singh Sodhi, a car mechanic from Amritsar, Punjab and his Parsi wife, also named Roshan and their son Gurucharan (Gogi),
Krishnan Subramaniam Iyer, a Tamil scientist from Chennai, Tamil Nadu and his Bengali wife Babita from Kolkata, West Bengal,
and a bachelor Popatlal Pandey, a newspaper journalist working for Toofan Express and from Bhopal, Madhya Pradesh.
There are also other recurring characters including Sundarlal (brother of Jethalal's wife Daya, from Ahmedabad, Gujarat), Abdul, the shopkeeper of the provisions store at the society entrance, reporter Rita Shrivastav, Inspector Chalu Pandey,Asit Kumarr Modi as himself, Jethalal's shop assistants - Natwarlal Prabhashankar Udhaiwala (Natu Kaka) and his nephew Bagheshwar Dadukh Udhaiwala (Bagha), who are often bent on doing the wrong job, and Bagha's fiancée Bawri Dhondulal Kanpuria.
The members of the society and other characters have a good psychological bond of love and sympathy for one another that makes them live like members of one family. They are often seen celebrating festivals and participating in events together. Although they are shown to live the lives of typical Indian families, the characters, more often than not Jethalal Gada, tend to find themselves in trouble, cropping up from routine activities that intensify in a comical manner. The quirks of the individual characters seek to enhance the humour quotient of the show. Whatever the nature of the problem that a member of the society encounters, all the other members stand by them to extend every possible help. In an episode, the resolution of the problem that a character faces is usually followed by a moral commentary by Taarak Mehta, which is meant for all the characters of the show as well as the viewers.
