Mayor’s ‘Flex-Free Mumbai’ Push: Illegal ads put OOH’s credibility under scrutiny again

As India’s ₹4,000-crore-plus OOH market formalises and premiumises, Mumbai’s crackdown on illegal outdoor advertisements puts the spotlight on enforcement and accountability 

Mumbai Mayor Ritu Tawde on Monday called for a citywide crackdown on unauthorised flex banners, posters and advertisements, nearly a year after the civic body introduced its fresh outdoor advertising policy. 

The campaign, proposed under the slogan “Shadu Bappa for 10 days, Flex-Free Mumbai for 365 days,” seeks to make that enforcement a year-round exercise. 

Tawde has written to BMC Commissioner Ashwini Bhide seeking immediate and strict action against unauthorised advertisements, with “zero tolerance” and no political discrimination. 

Her proposal calls for “political, social and commercial organisations” to be treated equally, while complaints against illegal flexes, banners, posters and stickers should be acted upon “within 72 hours,” with an action-taken report provided to the complainant.

Under the proposed system, every authorised outdoor ad would carry its "permission number, validity period, printer or agency details and a QR code", allowing citizens and civic officials to verify whether an advertisement has been legally approved. 

Banners without the required QR code could be treated as unauthorised and removed. “Repeat offenders, including printers, contractors and agencies” could also face blacklisting, her letter states. The proposal further calls for seized PVC flexes to be scientifically processed and recycled through the BMC’s Solid Waste Management Department.

For an OOH industry that is increasingly formalising, premiumising and embracing digital formats, the campaign brings the spotlight back on a long-standing problem: the unchecked proliferation of illegal advertising in India’s commercial capital.

Industry wants level playing field

The move comes at a significant time for the OOH industry. India's outdoor advertising market is valued at over ₹4,000 crore in annual ad spends and is projected to grow by around 5% in 2026, according to the Pitch Madison Advertising Report 2026. 

The medium has expanded beyond traditional roadside billboards, with airports, transit media, premium billboards, metro networks, street furniture, malls and digital OOH emerging as important growth engines.

Yet industry leaders point to an uncomfortable contradiction. “While organised OOH players invest in premium inventory, technology, measurement and compliance, unauthorised banners etc. are largely promoted by politicians through local players which is not under our purview,” industry leaders told e4m. 

While a few leaders admitted that hoardings owned by agencies are also used occasionally by political parties for celebrations and election purposes, they allege that payments are not always forthcoming, putting legitimate OOH businesses at an unfair disadvantage. 

According to an IOAA member, “This issue is not merely about visual pollution. Unauthorised inventory can potentially undercut legitimate media owners, deprive the civic body of licence revenue and blur the distinction between compliant and non-compliant OOH advertising.”

Policy exists; enforcement remains the test

The Mayor's campaign also puts the spotlight on the BMC's Advertising Guidelines–2025, notified on November 27 last year after the civic body replaced its previous 2008 framework. 

The policy introduced tighter norms around hoarding size, placement, digital displays and permissions, while also bringing newer formats and a more structured regulatory framework into the fold. The guidelines specifically state that temporary advertisements such as banners cannot be displayed without written permission and that unauthorized advertisements can be removed at the agency's risk and cost.

The new policy itself was positioned as an attempt to balance Mumbai's commercial potential with city aesthetics, safety and global outdoor advertising standards.

An outdoor agency head points out, “Mayor’s proposed campaign therefore raises a larger question for Mumbai's OOH ecosystem: after years of regulatory gaps and a year after making policy framework, can the BMC make enforcement as systematic as the rules themselves?”
