Full Form of OSR
What is OSR?
Open Space Reserve (OSR) refers to a portion of land set aside for public use, such as parks, playgrounds, gardens, or green buffers, as mandated by municipal authorities during urban planning and real estate development in India. This concept is integral to building by-laws and town planning regulations across states, ensuring that constructed areas do not consume all available land. OSR is typically a percentage of the total plot area—often between 10% and 20%—that developers must dedicate to the local civic body. The reserved land becomes public property, maintained by the municipality, and is used to enhance environmental sustainability, recreational facilities, and air quality. In Indian cities like Mumbai, Delhi, Bangalore, and Pune, OSR compliance is strictly monitored to manage rapid urbanization and prevent over-concretization. For students preparing for exams such as UPSC, state PCS, or Town Planning entrance tests, understanding OSR is crucial because it appears in questions on urban governance, land use policy, and the Real Estate (Regulation and Development) Act, 2016. The term also surfaces in environmental impact assessments and green building certifications. By securing open spaces, OSR helps mitigate flooding, heat island effects, and loss of biodiversity in crowded metros.
