BU Permission (Building Use Permission) is a legal certificate issued by the local municipal authority after a building's construction is completed. It confirms that the project has been developed according to the approved building plans and complies with applicable safety and construction regulations. In many states, BU Permission is also referred to as an Occupancy Certificate (OC), making it a crucial document that verifies a property is legally fit for occupancy and use. Whether you're buying property in one of the Best Residential Areas in Ahmedabad or any other location, verifying the BU Permission is an essential step before completing the purchase.
