The Mumbai Civic Body, also known as the Brihanmumbai Municipal Corporation (BMC), clarifies in its new Occupation Certificate (OC) amnesty SOP that housing societies cannot seek relief simply because their buildings lack an OC; valid valid Intimation of Disapproval (IOD) and Commencement Certificate (CC), as well as the developer’s NOC, remain key requirements, according to the Mumbai Civic Body’s circular.

Housing societies wishing to get an OC under the Brihanmumbai Municipal Corporation’s (BMC) amnesty policy must first establish that the building has the necessary approvals for its original construction, including an IOD and CC. The BMC’s Standard Operating Procedure (SOP) also demands a NOC from the developer or original construction application as part of the process, making these documents critical for societies looking to formalize their OC status.

The explanation is essential for thousands of Mumbai flat owners who live in buildings without an OC, as the amnesty is not intended to be a blanket method to regularize buildings regardless of approval history. In other words, a building’s eligibility is not determined by the absence of an OC. Before applying for the plan, housing societies must prove that the project received all necessary permissions throughout construction.To verify authenticity, the building for which an OC application is made under this scheme must have a valid IOD, an authorized plan, and a CC, according to the BMC.

The BMC further stated that if the housing society submits an application, a NOC from the owner or developer who initially submitted the development project or who has development rights is required. If the owner or developer does not give the NOC, the BMC stated in its circular that a notice will be issued to them under the Mumbai Municipal Corporation (MMC) Act of 1888.

The circular says that housing societies that are unable to present NOC or authorization letters from the prior owner or developer have submitted a letter to Maharashtra requesting that the MMC Act, 1888, be amended.

What is BMC’s amnesty program for OCs?

The BMC’s proposed amnesty scheme aims to bring relief to thousands of Mumbai housing societies that do not have a valid Occupation Certificate. The BMC plan allows eligible housing societies to receive an OC by paying prescribed charges, which are decided by elements such as the building’s form and size, as well as the nature and extent of permissions or breaches.

The plan is intended to help thousands of housing societies in Mumbai. Currently, almost 12 lakh residents live in nearly 25,000 residential complexes in the city without an OC.

Furthermore, the BMC’s condition specifies a deadline for applying under the OC plan. The proposed system will only apply to buildings occupied prior to November 17, 2016. Housing societies will be required to show papers such as property tax receipts or electricity bills to prove that the building was occupied prior to the deadline.

Mumbai’s redevelopment market has reached an important milestone as sales from redevelopment projects have overtaken sales from newly launched projects.

Mumbai Redevelopment Market Enters a New Phase

Mumbai’s real estate market is increasingly being shaped by redevelopment rather than traditional greenfield development.

A recent report presented at the NAREDCO Maharashtra Real Estate & Infrastructure Investors’ Summit 2026 showed that housing sales from redevelopment projects have surpassed new project launches for the first time.

The shift is significant because Mumbai faces one major constraint that developers cannot easily overcome — limited developable land.

More than 1,000 redevelopment projects

According to the report, more than 1,000 redevelopment projects have been launched in Mumbai since 2020.

These projects account for around 13% of Mumbai’s overall residential supply.

Redevelopment’s share of total housing sales increased to approximately 15% in 2025 and the first half of 2026, compared with around 6% during 2016–2021.

This shows how redevelopment is moving from being a niche segment to becoming one of the city’s major housing supply engines.

Why redevelopment is growing

Mumbai’s land scarcity is one of the biggest reasons.

Large portions of the city are already developed. Instead of finding completely new land parcels, developers can unlock additional residential supply by replacing ageing buildings and inefficient developments with modern projects.

For housing societies, redevelopment can potentially provide larger homes, modern amenities, better building infrastructure and improved safety.

For developers, redevelopment provides access to established locations that already have roads, public transport, schools, commercial activity and employment connectivity.

What it means for Mumbai buyers

The growing redevelopment market could significantly change where new homes come from.

Areas that already have established buildings could see more construction activity over the coming years.

For buyers, however, redevelopment properties require careful due diligence.

Buyers should verify MahaRERA registration, development approvals, construction timelines, developer track record, title documentation and the project’s rehabilitation obligations where applicable.

The bigger picture

Mumbai’s redevelopment boom is not simply about replacing old buildings.

It represents a broader transformation of the city’s existing urban fabric.

As land becomes increasingly scarce, redevelopment could become one of the most important sources of new housing in Mumbai.

A major piece of Mumbai’s former mill land could finally move towards development after the Bombay High Court cleared the way for the revival of Swadeshi Mills Company Ltd and development of its approximately 48-acre land parcel in Chunabhatti.

The property had remained caught in legal and liquidation-related disputes for more than two decades.

A long-running legal battle

Swadeshi Mills was founded by Jamsetji Tata in 1890 and was once one of Mumbai’s prominent textile mills.

The company eventually faced financial difficulties and was ordered to be wound up in 2005.

The resulting disputes over the company’s assets and land prevented the site from moving ahead with redevelopment for years.

The latest Bombay High Court decision changes the situation by allowing the revival proposal to proceed.

Why the land matters

Mumbai’s land scarcity makes large land parcels particularly valuable.

A 48-acre site in an established part of the city could have a substantial impact on the surrounding area depending on how the development is eventually planned and approved.

Development could potentially introduce new residential, commercial or mixed-use activity, although the final nature of development will depend on applicable planning approvals and project proposals.

Impact on Chunabhatti

The development could also influence the broader Chunabhatti area.

Large redevelopment projects can generate demand for supporting infrastructure, retail, services and improved connectivity.

However, large-scale urban development also needs to be matched with adequate roads, public transport, drainage, utilities and other civic infrastructure.

Impact on Mumbai’s real estate market

The Swadeshi Mills case highlights how redevelopment can unlock previously underutilised land in Mumbai.

As the city runs out of easily developable land, former industrial properties, ageing buildings and large redevelopment parcels are becoming increasingly important for future housing and commercial supply.

For Mumbai’s real estate market, the case is another example of how old land parcels can become part of the city’s next development cycle.
