The Tamil Nadu Assembly passed the Heritage Commission Act in 2012 to preserve old heritage structures. The structures will be categorised into three grades, namely, Grades I, II, and III. Grade I structures will be prime landmarks upon which no alterations will be permitted. Under Grade II, external changes on structures will be subject to scrutiny. Buildings under Grade III may be changed for 'adaptive reuse' with suitable internal and external changes."@en . . . . . . . . . . . . . . . . . . . . .
