Rapid industrialisation in post-Independence India triggered large-scale migration from rural areas to cities, intensifying pressure on urban housing. Chennai was among the cities facing this challenge. To address the growing demand, the City Improvement Trust (CIT) was established in 1947. It developed homes in various sizes and price categories, helping expand access to formal housing.
As housing needs extended beyond Chennai, the scope of CIT expanded. In 1961, under the Tamil Nadu Housing Board Act, the organisation was restructured as the Tamil Nadu Housing Board (TNHB), with a mandate to undertake housing development across the state.
Who It Serves
TNHB caters to four income categories: Economically Weaker Sections (EWS), Low Income Group (LIG), Middle Income Group (MIG), and Higher Income Group (HIG). This framework provides housing options for households across different income segments.
What It Has Built
According to data released by the Tamil Nadu government, TNHB has developed housing projects for families across income groups, including dedicated schemes for EWS and housing initiatives for slum rehabilitation. The board has also created rental housing for the general public and state government employees under dedicated rental housing schemes.
In addition to residential units, TNHB develops integrated neighbourhood projects that include schools, parks, roads, and civic infrastructure. Public-purpose sites within these layouts are allotted through e-auctions.
Landmark Projects
TNHB's developments include some of Chennai's well-known residential localities, such as Arignar Anna Nagar, Kalaignar Karunanidhi Nagar, Ashok Nagar, Besant Nagar, and JJ Nagar. Over time, its presence has expanded to cities like Madurai, Coimbatore, and Trichy, as well as several smaller towns across Tamil Nadu.
Allotment Process
Plots, flats, and houses developed by TNHB are allotted to the general public on a first-come, first-served basis through the board's prescribed social rotation system.
What Next
TNHB is pursuing the redevelopment of older housing colonies through Public-Private Partnership (PPP) and Joint Venture models. The Tamil Nadu Housing Board Act, 1961, is also being revised to align with contemporary requirements.
According to the board, its focus areas include transparent pricing, clear title deeds, environmentally conscious construction practices, prior regulatory approvals, third-party quality supervision, and structural designs certified by institutions such as IITs or Anna University.
