Maintenance charge for Varying size PLOT holder Society

PLOT holder society is having various size plots. Many PLOT owners have purchased more than 1 Plot on their name. ONE-Time maintenance was taken by developer at the time of purchase of each plot. Due to fraud of developer, he misused ONE-Time maintenance. Hence all Plot holders formed Society and started collecting maintenance charge to run the society for common services such as security, house-keeping, street Lighting. in AGM due to majority of such multi Plot owners dominance, maintenance charge was decided on paying unit i.e. even though 1 person has 10 plots on his name, but resides only on one plot, it is called 1 paying unit. Here injustice is felt, as 1 plot holder pays same maintenance amount and person having 10 plots also pays same maintenance amount, but enjoys / consumes more society expenditure due to increased society amenities for example - Security boundry wall construction. i.e. When he is having 10 plots, so society security boundry wall length is also increased and society spending for him also increases. So as per logic, he should pay more maintenance charge, as society is spending more for him. My question is - Is there any rule for how to calculate maintenance charge for PLOT holder’s society.
