Greater Bengaluru Authority or GBA (formerly BBMP) has introduced a new model of city administration for Bengaluru. GBA is formed under the Greater Bengaluru Governance Act (GBGA), 2024. The GBA is formed to improve governance, decentralization, and service delivery.
Under this Act, the existing Bruhat Bengaluru Mahanagara Palike (BBMP) is being restructured into five independent municipal corporations, each headed by its own Mayor and Commissioner, but overseen by a Greater Bengaluru Authority for coordination.

The Greater Bengaluru Governance Act, 2024
The Greater Bengaluru Governance Act, 2024 (Karnataka Act No. 36 of 2025) is a law passed by the Karnataka legislature to redefine and reorganize the governance and administration of Bengaluru and its metropolitan region.
Its purpose is to introduce a framework of institutions, processes, and powers for effective urban governance in what is called the Greater Bengaluru Are.
The ACT replaces and supersedes prior laws (notably the BBMP Act, 2020) governing Bengaluru’s municipal administration.
The Need For The Greater Bengaluru Governance Act, 2024
- Bengaluru’s growth over decades created a highly fragmented institutional setup: multiple civic agencies (water, transport, development authorities) operating with overlapping roles and poor coordination.
- The existing system under BBMP and associated Acts was not structured to handle metropolitan-scale issues, large infrastructure projects, or uniform planning across expanding suburbs.
- The new Act aims to integrate planning, streamline functions, and strengthen accountability and citizen participation across the larger urban region.
