A Fire NOC (No Objection Certificate) is a document issued by the fire department or fire authorities certifying that a building or premises comply with fire safety regulations. It is a prerequisite for obtaining a Fire License in Tamilnadu. On the other hand, a Fire License is a legal document issued by the Tamil Nadu Fire & Rescue Services, which permits the building or premises to be used for the intended purpose after verifying that the building or premises have adequate fire safety measures in place to prevent and tackle fires.
