Construction and real-estate stakeholders say Tamil Nadu’s self-certification building permit system is now helping create “mini” industrial estates, especially around established industrial hubs.
The state first introduced self-certification approvals in 2024 for residential buildings up to 3,500 sq ft on plots up to 2,500 sq ft, enabling applicants to obtain permits without alleged interference at local bodies. With the model receiving public support, demands grew to extend the facility to factory buildings as well.
Following this, a plan was announced to grant self-certification approvals for factory buildings up to 7,500 sq ft on plots up to 5,000 sq ft. A government order was issued in October last year, though the rollout was delayed due to time taken to develop the online platform.
After the change in government, the current administration launched the facility for public use, drawing a positive response from industrial circles. Stakeholders say the simplified process is encouraging small units—such as ancillary manufacturers supplying parts to large companies—to build their own premises.
Property valuer B. Balamurugan said landowners near large industrial parks, including areas around Oragadam and Sriperumbudur, are subdividing holdings—ranging from about 20 acres and above—into 5,000 sq ft industrial plots, securing DTCP approvals and beginning sales. He added that work has begun in more than 20 locations, with the policy seen as a potential turning point for small industries.
