Do I Need To Allow My Neighbor To Allow Into My House For Painting His Wall Even Though They Didn't Leave Any Gaps B/w Their Boundary Wall And My Lan

Hi everyone,
I am currently facing a boundary dispute with my neighbor and need some advice on how to handle the situation legally and effectively.
Recently, I surveyed my land due to an ongoing issue with my neighbors. After the survey, I discovered that my neighbors had built their boundary wall without leaving any space between my land and their wall. Now, I am planning to fence my land along the boundary.
However, my neighbors is causing problems and insisting that I must leave a 1.50-foot gap between my fence and their boundary wall to allow them space to paint their wall. I am unsure whether this request is legal and how to proceed.
Here are my specific questions:
Is it legally/necessary required to leave a gap between my fence and their boundary wall for maintenance purposes?
How can I approach this situation to avoid further conflict?
If necessary, how should I approach the police station to file a complaint or seek assistance
Note: I'm not interested to leave the gap as they given so much mental torture to my family.
