This discussion explores the fairness of common area maintenance charges, which vary based on flat size (1, 2, or 3 BHK). The core question is whether it's justifiable to charge different amounts (Rs. 1400, 1800, 2000) when owners theoretically have equal rights to common areas. The consensus suggests that charges are determined by the Resident Welfare Association's (RWA) calculation methods or society bylaws, and owners should verify these rules.
