Mumbai Makeover Redevelopment Handbook 2025, Published on Jul 17, 2025

Mumbai initially comprised only of the island city but gradually expanded northwards towards the suburbs. The BMC city limits now include the island city and the suburbs, which extend to Dahisar, Mulund And Trombay. In this densely built city, many buildings are over 40 to 50 years old. A considerable area of Mumbai is also covered by dense slums, which lack proper infrastructure and hygienic living conditions. These factors pose a challenge to cater to the ever-increasing population needs and upgrading infrastructure for the city. Moreover, the high population density and limited land availability results in high real estate pressure.
In this context, ‘redevelopment’ has emerged as a key planning tool to optimise land use, increase housing stock, and improve urban infrastructure without expanding the city’s footprint. Under the Maharashtra Regional and Town Planning Act, 1966 (MR&TP Act, 1966), regulations for redevelopment were formally introduced in the BMC’s Development Control & Promotion Regulation of 1991 and later revised in the DCPR 2034. These regulations introduced incentives for redevelopment like higher Floor Space Index (FSI), rehabilitation area entitlement, development rights, and so on. They are applicable to cessed buildings, MHADA buildings, slums and other old, dilapidated or dangerous structures. Redevelopment has significantly shaped Mumbai’s skyline. A city once dominated by textile mills, low-rise buildings, and modest infrastructure, it gradually saw a shift in development in the last 20-30 years.

Redevelopment basically means rebuilding old, dilapidated or defunct buildings to upgrade them with better quality structures with new infrastructure and amenities. Most older buildings in the city are not structurally stable, have poor infrastructure or have not consumed full FSI as per current regulations. Redeveloping these structures allows the occupants structurally safe spaces with improved infrastructure, often with higher FSI and added compensatory area depending on the regulation
under which redevelopment is carried out. Due to the higher FSI, developers can generate saleable components, making the project financially viable for them. The regulations also make provisions to provide space for public amenities or open spaces to cater to the neighbourhood
In any redevelopment scheme, key stakeholders include the existing residents/ society members of the building who are entitled for redevelopment, landowners (Maharashtra Housing and Area Development Authority-MHADA, in case of cessed MHADA buildings), any developer willing to undertake the project, and even the planning authority (here, the BMC), which grants the development permission for the project. Legal advisors, architects, and other industry experts may also be taken on board to support the project execution. The redevelopment can be initiated either by the existing residents or landowners.

The DCPR 2034 recognises the need for different approaches for the redevelopment of diverse urban fabric and different types of buildings in the city. Under Regulation 33, It lays out the guidelines and framework to undertake redevelopment for
specific areas and buildings. The most widely used regulations among these include the 33(5) for building in MHADA layouts, 33(7) for cessed buildings in island city, 33(9) for cluster redevelopment, and 33(10) for slum redevelopment. These regulations have become integral to Mumbai’s urban renewal strategy to balance development and residents’ rights.

The use of FSI is the key in formulation of these regulations. FSI controls how much you can build on a piece of land. Redevelopment regulations offer higher FS, almost double than regular construction projects, making them attractive for the builder. The higher FSI is given to ensure that the existing residents get the minimum carpet as set by the government, while the remaining built-up area can be sold by the builder in the open market. Additional incentive FSI based on the project and fungible FSI up to 35% over and above permissible FSI (added in DCPR 2034) allowed on the payment of premium, can also be availed by the builder for additional built-up area

These regulations impose strict norms for the rehabilitation component in order to safeguard the rights of the existing residents it is termed as “rehabilitation area entitlement” Based on the plot size and type of redevelopment, the residents may also be entitled to additional compensatory. carpet area. The DCPR also mandates irrevocable written consent of residents, from 51% to 70%, depending on the type of redevelopment
To address the need of more public infrastructure in the redeveloped areas due to increased population density, the DCPR levies a development cess, in addition to development charges and premium for additional FSI, which is to be paid to the authority. This amount is earmarked for upgrading public infrastructure such as roads, drainage, water supply, and open spaces in the redeveloped neighbourhood to make the urban renewal schemes more sustainable.
A provision of corpus fund is also added, which is to be handed over to the new housing society by the developer and shall be utilised for maintenance of the new buildings for up to 10 years

Regulation 33(5)
MHADA has built many housing schemes in Mumbai to provide affordable housing to the low-income and middle-income groups. Over the years, these structures have become structurally unsound or in a state of despair. DCP Regulation 33(5) allows these schemes to be redeveloped by MHADA or by the housing societies by giving them higher FSI up to 30 or n4.0 in soma areas if the plot size is more than 4000 sqm and adjacent is minimum 18.Om or more. The existing residents are entitied to a minimum carpet area with an additional entitlement anes based on the size of the plot, thus safeguarding their interest in the project. The additional Incentive FSI allows the developer to get more built-up area as a saleable component making the project financially feasible It is important to note that if the housing society/developer a undertaking the redevelopment themselves, written consent of at least 51% of existing residents is required to take the project forward

Regulation 33(7)
Similarly, regulation 33(7) considers cessed buildings existing prior to 31/09/1969) in island city or old buildings belonging to the Corporation. These buildings occupy a significant chunk in Mumbai’s housing stock, accommodating many families where most of them live as tenants. These structurally vulnerable buildings can be redeveloped by the landlords or co-operative housing societies under 33(7) with higher FSI upto 3.0 and additional area entitlements based on the need of the rehabilitation area and incentives availed by the builder. The regulation states that each tenant is entitled from a minimum of 27.88 som. to maximum 120 sqm. carpet ares in the new building. Like the 33/5), written consent of at least 51% of existing residents is mandatory. The 30(7) further categorised into two parts-33(7)(A) for dilapidated unsafe building in the suburbs and extended suburbs and existing authorised non-cessed tenant occupied buildings in Mumbai City and 33(7)(8) for existing residential housing societies excluding cessed buildings. Each section has a speciñc framework with respect to who can undertake the redevelopment, additional FSI and other incentives.

Regulation 33(9)
Redevelopment of individual buildings and housing societies in congested neighbourhoods poses challenges like small plot sizes, narrow approach roads and difficulty in accommodating amenities and infrastructure. Such standalone developments

do not lead to holistic urban renewal For a strategic urban renewal of such dense arsas, Regulation 33(9) facilitates duster redevelopment carlier urban renewal scheme. As the name suggests, a group or cluster of plots of minimum total 4000 sqm can be merged and redeveloped as a single plot. This helps to facilitate better planning, open spaces, setbacks and road widths in the layout. FS1 up to 4.0 is allowed with added incentives like additional compensatory area and fungible FSI upto 35%. Such schemes are envisioned to not only rehouse the residents but carry out a holistic and sustainable urban renewal. However, obtaining consent of at least 70% of eligible residents, legal
disputes on individual plots remain key hurdles to implementing this scheme. The regulations include 900 chawts in Naigaon, Worll and even the Dharavi Redevelopment Project.

Regulation 33(10)
The most impactful regulation for redevelopment is the 33(10) for slum rehabilitation. Slums house nearly 40% of Mumbai’s population on nearly 10% of the city’s land. This regulation aims to house the slum dwellers in formal housing by providing them with free new buildings. Slums before 01.01.2000 are eligible for this redevelopment. With basic FS1 of 3.0 and other benefits the redevelopment regulations provide a structured framework to renew the aging and unsafe housing. When properly implemented, redevelopment projects can be transformative not only on an individual but also community level like incentive FSI and fungible PSI, builders are able to generate high enough built-up area for rehabilitation as well as sale in the open market, identifying eligible beneficiaries requires comprehensive surveys by the developer. Here, the Slum Redevelopment Authority also plays a pivotal role in initiating and approving of projects. Much like cluster redevelopment, this regulation allows for an area-based development sourcing comprehensive planning.

The redevelopment regulations provide a structured framework to renew the ageing and unsafe housing. When property implemented, redevelopment projects can be transformative not only on an individual but also community level. However, Implementation of these projects poses numerous challenges. Obtaining the required consent can be time consuming due to internal disputes or misinformation. The financial viability of the project also largely depends on the market trends and time requirest for the approval process. Handling legal issues of property disputes, development rights may also affect the project. Managing the temporary accommodation of residents
curing the construction is also a crucial stage. Delays in the project completion can lead to unrest, rift between residents and builders or even breakdown of the project.
While the regulations are intended for the purpose of providing better quality of life for residents, they often criticised for being too bullider-friendly, sidelining the actual need of the community at large, and leading to gentrification, particularly in slum rehabilitation. Moreover, the carrying capacity of the area gets severely affected due to the inconsistency of rate at which population density rises and the lack of proportionate upgradation of public infrastructure.

Despite this, redevelopment regulations remain a critical instrument for Mumbai’s upgradation. They address the problem of urban renewal in a dense city through context-specific strategies. Community participation, transparent governance, and genuine political will can shape these regulations to overcome any loopholes and act as a tool for sustainable and integral urban renewal.
