Exclusive Use

Condos and gated single family homes have separate exclusive use rules pertaining to parking. Does exclusive use extend to on street parking
in gated communities?

I have a friend on another street who has a family member that is wheelchair bound, and it is much easier for him to park in front of his home to lower the
wheel chair ramp right on from the sidewalk that leads to his front door. The ticker here is there are no sidewalks in front of his house and a neighbor
always parks in front of his house and he has to stand his vehicle in the street to load with the wheelchair ramp.

There has always been this unwritten rule among neighbors that you don't park in front of someone else's house, is there any protection in gated private street
communities?

If they have a disability hang tag for their vehicle, what about installing disability parking signs in front of their home? Of course, it wouldn't stop anyone else who had a hang tag, but it could prevent most people from parking there.

Usually the board can make rules for privately owned streets. One thing that some communities do is assign reserved spaces for people with disabilities. They might do it at your friend's expense as they generally are not required to make accomodations at the association's expense.

Let's just call it zero frontage, actually around 3 feet, at a slight incline.
