Constructing a building in India typically needs a sanctioned building plan from the local development authority, and depending on size and location, a fire NOC, environmental clearance for large projects, airport height clearance near airports, and other departmental NOCs. On completion, the completion certificate and occupancy certificate confirm the building can be used.
