BMC Standardizes Amenity Open Space (AOS) Utilization Policy under DCPR 2034 for Mumbai Redevelopment


Issued by: Development Plan Department, Brihanmumbai Municipal Corporation (BMC) | 16 April 2026

Background

This comprehensive administrative circular has been issued by the BMC's Development Plan Department to resolve a widespread operational issue: a large number of Amenity Open Space (AOS) plots handed over under legacy DCR 1991 and active DCPR 2034 frameworks have remained completely vacant, idle, and unutilized for prolonged periods. Under past administrative practices, the absence of standardized, time-bound execution frameworks directly deprived citizens of essential public utilities.

To reverse this pattern, the Municipal Commissioner directed the formulation of a unified strategy to systematically plan and convert these parcels into functional urban assets. Crucially, the new mandate dictates that the development of these spaces must be achieved without utilizing any municipal funds from the Corporation. Instead, the policy shifts the fiscal responsibility to external mechanisms like Corporate Social Responsibility (CSR) tracks to address localized ward deficiencies efficiently.

 

New BMC circular enforces zero-cost development, strict execution timelines, and mandatory GIS mapping for handed-over Amenity Open Space plots in Mumbai.


These amenity plots should not be given directly to anyone. The Chief Engineer (D.P.) should prepare a comprehensive and all-inclusive policy on how to develop these amenity plots without using the funds of the Corporation.

Municipal Commissioner, BMC | 01 January 1970


 

Key Highlights

Zero Municipal Funding Mandate: Requires all handed-over Amenity Open Space (AOS) plots to be planned and developed without draining the financial resources of the Corporation.

Mandatory GIS Database Integration: Establishes a strict system check requiring all layout sub-divisions, amalgamations, and AOS layouts to be updated in the official DP 2034 GIS database before the Building Proposal department can issue an Occupation Certificate (OC).

Rigid Execution Windows: Dictates that planning for plot usage must be finalized within 6 months of handover, and structural execution must be completed within 24 months from the date of work commencement.

Compulsory Ward Deficit Registers: Instruct every administrative ward to maintain a dynamic inventory log tracking localized amenity shortages to prioritize site development logically.

Public Representative Consultation: Mandates ward offices to formally collect and integrate structural recommendations from local elected representatives when deciding the final public use of a plot.

What Has Changed?

Particular

Earlier Position

Revised Position

Development Deadlines

AOS plots remained vacant indefinitely without clear planning or construction deadlines.

Planning must finish within 6 months of handover; construction must be completed within 24 months of commencement.

GIS Mapping Checkpoints

Handover files were processed independently without being digitally linked to final building occupancy clearances.

Layout updates and AOS data must be mapped into the DP 2034 GIS database before the Occupation Certificate is issued.

Funding Strategy

Heavily reliant on municipal allocations, which frequently stalled development.

Zero municipal funding permitted; ward offices must utilize Corporate Social Responsibility (CSR) avenues.

Allotment Logic

General allocation without a structured local deficiency audit.

Regulated via a mandatory "Ward Amenity Deficit Register" linked with local public feedback.

Built-up Amenity Deployment

No specific timeframe is mandated to open handed-over structures for citizen use.

Respective Assistant Commissioners must deploy built-up amenities within 3 months of formal handover.

Detailed Explanation

1. Statutory Allotment and Split Layouts

The circular divides handed-over plots into clear, area-based tranches across three distinct regulatory frameworks:

  • DCR 1991 Layouts: Scale from a basic 5% handover up to 25% for master layouts, requiring at least half of the larger plots to be cataloged as Public Open Spaces (POS).
  • Regulation 14(A) Layouts: Mandates a flat 5% allocation for mid-sized properties, shifting to a progressive mathematical formula once past the 10,000 sq.m. boundary.
  • Regulation 14(B) Industrial Conversions: For conversions under 2,000 sq.m., developers can choose to surrender either 10% open land or 5% built-up space at Zonal FSI on the ground floor. Larger plots follow a strictly indexed scale up to 25%.

2. The GIS and Occupation Certificate Checkpoint

To eliminate gaps in record-keeping, the Building Proposal Department is instructed to enforce an absolute compliance gate. Before any final Occupation Certificate (OC) can be processed, the architect must prove that the layout modifications and the exact boundaries of the surrendered AOS have been fully updated in the official DP 2034 GIS database.

3. Ward Operations and Alternative Funding

Every administrative ward must keep an updated "Ward Amenity Deficit Register". Instead of allocating plots arbitrarily, the ward must cross-reference shortages with community requests and recommendations from public representatives. Because drawing from the BMC treasury is prohibited, ward offices must use Corporate Social Responsibility (CSR) avenues, subject to prior administrative approval from the Additional Municipal Commissioner.

Opinion on FAQ related to circular

Q  

Can a developer secure a final Occupation Certificate (OC) if the handed-over Amenity Open Space (AOS) is not updated in the municipal database?

  A
No. The circular explicitly requires the Building Proposal Department to verify that the approved plans, layout sub-divisions, and AOS details are successfully uploaded to the official GIS database of DP 2034 before an Occupation Certificate can be issued.
  A
Under Regulation 14(B) of DCPR 2034, the developer can choose to hand over either 10% of the land area as open land, or 5% of the built-up area calculated at the Zonal (basic) FSI as residential or commercial premises located preferably on the ground floor.
  A
The policy mandates that planning must be completed within 6 months and construction within 24 months of commencement. No amenity plot can be left undeveloped past these limits without special written permission and recorded reasons from the Municipal Commissioner.
