We are a NSW strata plan and have had a designated wash car area for 40 years with no apparent problems. I’m not sure how it originated but this car wash area is near a water tap with hose attached.
As only a few people use this car wash area and always return their cars to their own designated car spaces immediately after washing, there doesn’t seem to be a problem.
The car wash area is not a designated visitors car space but just the plans common property.
Occasionally, and by that I mean a few times a year, visitors do park there but hardly more than overnight.
Our residents do not seem to have a problem with this.
Unfortunately the car wash sign was taken down during painting of a fence and not replaced.
We have 9 designated visitors car spaces.
