What are the powers of the RWA?

Hi, I have a plot in a BDA approved gated community layout. Planning to construct a 4-kitchen building as per BBMP/BDA approved plan & fully adhering to BBMP/BDA by-law rules. However, few residents in layout objecting to 4-kitchen and enforcing me to construct only 1 or 2-kitchens, citing Residents Welfare Association (RWA) guideline/rule that allows max 2-kitchens. My question: Does RWA has power to reject competent authority approved plan and define own rules? on matters outside of scope Isn't this contravention local laws or law of the land? and infringement of my rights over property?
