Do I have legal grounds against the builder's harassment?

Hello. I live in a society in Ahmedabad where the builder also resides. He insists on reserving a common parking spot near his home exclusively for his car, despite it being designated for any resident. Whenever we park there, he knocks on our door, demanding we move our car. Out of courtesy, we've often complied to avoid conflict. However, this persistent behavior is concerning. While other residents tolerate his actions, I feel this is enabling his bullying. I’m considering filing a case in consumer court, as his behavior seems like bullying/mental harassment. The society chairman has shown no interest in resolving this. Do I have any legal grounds, and could a legal route offer a solution? Thank you for your guidance.
