Society maintenance charges rules for different area flats
I am leaving in Pune. In our society there are two buildings with flats of different areas as 1 & 2 BHK. Builder took maintenance charges bases on area of flat from owner. Now, we are going to take handover of society from the builder and body members have assigned same maintenance for all (1 BHK and 2 BHK flats) and same reserve fund for all. But I believe there should be some less payable amount (grant) either in maintenance or in reserve fund amount for 1 BHK. Please let me know what should be the rules to calculate the maintenance and reserve fund amount where society have different size of flats (1 BHK and 2 BHK flats) ?
I visited many of societies where they all have different rules. (i.e., some has maintenance charges based on area of flat and same reserve or sinking fund payable amount for all, whereas some has same maintenance amount (per flat) and reserve fund based on area.). Please guide.
Thanks & regard,
