Set the point light s baking property to mixed or baked then bake your lighting data using the lighting tab.
You can simulate this in shaders or use raycasts to see if the light is behind a wall.
Shadow maps are a kind of fickle technology.

As an off the wall guess though it looks like your trying to force beta your lighting values far beyond their limitations that is causing the lighting solution to bleed.
These options have obvious edge cases that can t be easily resolved.
I believe this has something to do with culling masks or light culling.
Place it just behind your wall so that it blocks the light from leaking out.

This is caused because the use inverse squared falloff is set to on by default forcing you to have to use way more lights than whats needed or to set it s value far outs side acceptable values.
I m not sure if you are familiar with gaia but you create a new scene which adds a default directional light and default terrain.
I was wondering how i could go about culling the lights so they no longer shine through walls.
In some situations normal bias can cause an unwanted effect called light bleeding where light bleeds through from nearby geometry into areas that should be shadowed.

In that case you ll need to be a bit more clever.
Note that this will take a long time depending on the size of your scene and the number of lights 3.
When i change the buildings walls to static nothing changes.
If a light is next to a wall on one side you can see it on the floor on the other side.
Position these to block any light leaking through the bottoms of walls.
It will pay dividends to learn how they work what the settings do and how to work around problems like this.
Any help is greatly appreciated.
Shadows are the obvious answer however i assume you are using lite and that s not an option.
That s why shadows exist.
