Across Mumbai, Thane and the wider MMR, thousands of co-operative housing society buildings are more than 30 years old. Traditionally, societies have handed redevelopment to a builder, who takes the extra floor space and most of the profit. Self-redevelopment is the alternative: the society does it itself. The biggest question every society asks is how to fund it.

Self-redevelopment vs builder-led redevelopment

In builder-led redevelopment, a developer finances and builds the project, gives members their new flats, and earns its return by selling the additional flats and using the incentives.

In self-redevelopment, the society's members plan, finance and build the project through professionals they appoint — an architect, a project management consultant (PMC) and a contractor — and keep the surplus themselves. The trade-off is risk: the society takes on cost overruns, approvals, sales and the loan.

The policy framework so far

  • 2019: The state set up an expert committee and issued a resolution on 13 September 2019 offering incentives for self-redevelopment of registered housing societies with buildings over 30 years old. Housing Policy 2025 lists them as including additional FSI, a concession on TDR, reduced premiums, a loan-interest rebate, ₹1,000 stamp duty on members' agreements, single-window approvals and completion timelines.
  • 2023: A resolution dated 29 August 2023 cut the single-window approval timeline to three months, made the State Co-operative Bank the statewide nodal agency (working through district central co-operative banks), and named Mumbai District Central Co-operative Bank as the nodal agency for Mumbai, Mumbai Suburban and the MMRDA region. A separate notification set ₹1,000 stamp duty on the agreement between the society and its existing members, subject to conditions.
  • 2025: The state's Housing Policy 2025 acknowledged that implementing orders for many of the 2019 concessions were still to be issued, and proposed a State Self-Redevelopment Cell with ₹2,000 crore of initial share capital to support societies. In September 2025 the state set up a Self/Group Redevelopment Authority, with MHADA as nodal agency, to take recommendations forward; as of December 2025 a committee's recommendations were still being studied.
  • 2026: On 30 September 2026, the Co-operation Department issued a new order on the redevelopment process for housing societies, replacing the 2019 directive. It is reported to set new meeting, voting and tendering rules — including for appointing a contractor in self-redevelopment. Check the official text before you hold your general body meetings.

The practical message: treat concessions as available only once your planning authority has notified them, and build your feasibility on what is in force today.

Who lends, and on what terms

  • Co-operative banks. Under the 2023 resolution, societies in the MMR — including Thane-district towns — can approach Mumbai District Central Co-operative Bank, and societies across Maharashtra can approach the State Co-operative Bank network through their district central co-operative bank.
  • Published terms. Mumbai District Central Co-operative Bank's published policy describes loans of up to 85% of project cost (₹50 crore or more, subject to exposure norms), a tenure of up to seven years including a two-year moratorium, 100% member consent, conveyance in the society's name, and an escrow mechanism with the plot and new building mortgaged to the bank. Terms change, so confirm current conditions with the bank.
  • RBI's rule. In June 2022, RBI allowed state and district co-operative banks to lend for commercial real estate – residential housing, within their overall housing-finance limit of 5% of total assets. That cap limits how much any one co-operative bank can lend across all such projects.

The process, step by step

  1. General body resolution to explore self-redevelopment, following the current Co-operation Department procedure.
  2. Appoint an architect and PMC through a transparent selection process.
  3. Feasibility study and project report — costs, FSI available, rent and shifting, sale component and cash flow.
  4. Approvals from the planning authority through the single window.
  5. Select a contractor through tenders.
  6. Loan sanction from the bank, with security and escrow arrangements.
  7. MahaRERA registration of the sale component, unless exempt.
  8. Members vacate, construction begins, and funds are disbursed in stages on the PMC's certification.

How the money flows — and gets repaid

A self-redevelopment loan typically covers construction cost, TDR and premiums, professional fees, and members' rent and shifting costs. It is repaid from two main sources:

  • Sale of free-sale flats — the additional flats the society sells in the open market.
  • Members' contributions — for example, for extra area members choose to buy.

Most loans have an interest-only moratorium during construction, followed by instalments.

The RERA factor. If the sale flats are registered with MahaRERA, at least 70% of buyers' payments go into a separate, lien-free account released only in step with certified progress. That affects how quickly sale proceeds can repay the bank, so build it into the cash-flow plan — see our guide to the MahaRERA 70% account.

Thane and MMR: what's different

Societies in Thane-district towns within the MMR fall under the nodal-bank arrangement for the MMRDA region. Planning rules differ, though: much of the Thane belt is governed by the state's unified development control regulations rather than Mumbai's DCPR 2034, so FSI incentives available in Mumbai may not apply in the same way. Check with your planning authority early.

Risks to plan for

  • Member consent — loans may require 100% consent, and disputes can stall projects.
  • Cost overruns and delays — the society, not a developer, bears them.
  • Unsold sale flats — slow sales delay repayment.
  • RERA cash-flow lock-in — 70% of buyer money is released only with progress.
  • Incentives not yet notified — don't count on concessions that aren't in force.
  • Lender capacity — co-operative banks' 5% housing-finance cap limits how much they can lend.
