The Sangguniang Barangay serves as the legislative arm of the smallest political unit in the Philippines – the barangay. Comprising the Punong Barangay (Barangay Captain) and several Kagawads (Council Members) as stipulated on Section 387 of RA7160 otherwise known as the Local Government Code of 1991, the Sangguniang Barangay plays a crucial role in local governance.

Its primary duty is to enact ordinances and resolutions that address the specific needs and concerns of the barangay residents. These legislative measures may cover a wide range of issues, including public health, safety, sanitation, and community development. Furthermore, the Sangguniang Barangay is tasked with approving the annual budget proposed by the Punong Barangay, ensuring that resources are allocated appropriately to meet the barangay's needs.

The council also acts as a checks-and-balances mechanism, reviewing and scrutinizing the policies and programs initiated by the Punong Barangay. Additionally, the Sangguniang Barangay is involved in the appointment of certain local officials, such as the Barangay Secretary and the Barangay Treasurer. Overall, this grassroots level of governance is essential for fostering community development, maintaining peace and order, and addressing the specific concerns of barangay residents.
