New high-rise rules to fast-track Mumbai redevelopment. Here's how

The Maharashtra government has eased approval norms for high-rises up to 180 metres in the country's financial capital Mumbai. While the change shifts greater responsibility for safety checks and regulatory oversight to the civic administration, industry experts see it as an opportunity to streamline approvals, cut red tape, and enable faster urban renewal in the country’s most vertical city. ET finds out.

What exactly has changed?
The Maharashtra government has amended the Development Control and Promotional Regulations (DCPR) 2034 to relax approval norms for high-rise buildings in Mumbai. The Municipal Commissioner can now approve projects up to 180 metres in height without referring them to the High Rise Committee, provided the plot size is 2,000 sq m or more. Developers must submit structural and geotechnical designs certified by two qualified experts from recognised institutions such as IIT Bombay, VJTI or Sardar Patel College of Engineering.


What was the earlier process?
Until now, all projects taller than 120 metres required scrutiny by the High Rise Committee, which reviews proposals for fire safety, structural stability, wind impact, and traffic management. This process often extended approval timelines, affecting project costs and viability. Developers have long argued repetitive reviews added procedural delays.

Why has the rule been changed?
Officials say the change is intended to streamline approvals and align with modern construction practices. Mumbai’s redevelopment-heavy market has several projects in the 120-150 metre range waiting for clearance. By empowering the commissioner’s office to approve such buildings, the government aims to cut bottlenecks and improve ease of doing business. The move also reflects confidence in advanced engineering and institutional certification.

What happens to towers above 180 metres?
Buildings taller than 180 metres or those with a slenderness ratio (height-to-width ratio) of more than 9 will still require approval from the High Rise Committee. The new rule applies only to mid-range tall buildings that meet the prescribed technical and plot-size norms. Super-tall structures will continue to face multi-agency review.

How are safety checks being ensured?
Developers will now need expert certification from reputed technical institutions before seeking approval. MCGM will continue to verify documents, and officials said random audits and site inspections could be undertaken. The Commissioner’s office is also expected to strengthen its in-house technical cell to handle the added responsibility.

What are the key concerns?
Urban planners and fire officials have warned that easing procedural layers should not dilute safety checks. Mumbai’s firefighting equipment can reach only around 90 metres, leaving taller towers dependent on internal systems. Experts also flagged the need for infrastructure upgrades to support increased vertical density.
