Under the new system, developers of high-rise buildings will no longer need to wait for individual NOCs from various departments. Instead, once the project complies with the set regulations and guidelines, it will automatically receive deemed NOCs. This change is expected to significantly reduce the time and effort involved in obtaining approvals, allowing for faster project execution.

The implementation of deemed NOCs is part of a broader initiative by the CMDA to modernise and simplify the regulatory framework for urban development. By minimising the need for multiple approvals, the CMDA hopes to create a more efficient and transparent process that benefits both developers and residents.

Critics argue that while the move may speed up approvals, it could also raise concerns about oversight and compliance. Ensuring that high-rise buildings meet safety and environmental standards remains a critical issue, and the CMDA will need to maintain rigorous checks to address these concerns.

Overall, the introduction of deemed NOCs represents a significant shift in Chennai's approach to urban development, reflecting a broader trend towards streamlining regulatory processes to foster growth and development in the city.
