Thanks for any experience in this matter!
Step 1 is to determine the status of the road:
1) co-ownership of land where the road was built.
2) right of way to pass through the other property to reach yours and shared maintenance costs of the road.
Old person dies and descendant inherits. Landlocked neighbor with white hairs patronizes the younger new owner. The neighbor granting the passage through his new property took it personally .
Lawyer came to read the yellow papers and consulted the land registry. What was written was a right of way to access the landlocked property but no specific words about "X meters wide asphalt road". Lawyer interpreted this as "walking is enough" to grant access to the landlocked property and fulfill the obligations agreed by late grandpa. So, the access with a car was only a "favor" not supported by anything.
Next, the neighbor granting passage made sure everyone in town learned about this. Then, proceeded to offer the land where road was for a ridiculous amount to the landlocked neighbor. Landlocked neighbor found himself in a situation with no car access to property and every one town knowing about it. His property value was not zero, but took a serious hit. After some negotiation and lots of tears of the neighbor that initiated the dispute the transaction was made.
About the eyesores, it's a bit more complicated. Rules are different in every gemeinde. In some places, there's a ban for mobile homes (wohnmobile). maybe in your gemeinde there's a rule about commercial vehicles and residential areas. Or, are they parking beyond the asphalt limits on some grass? There might be a regulation on that. But, these are indirect approaches, unless said parked vehicles block your way, not much to do.
Take a breath, read local regulations, and maybe talk to a lawyer. Until you know where you're standing, better say nothing.
No, I'm asking if there is a legal limit to the number of vehicles that one can park on one's property. Try reading my post again, I know it's challenging to try to read more than one sentence.
Our building has a large Vorplatz in front of the garages and some of the neighbours argued that we should mark it up as parking spaces. One of them did some drawings and I think came up with 10 spaces or so. When they asked the Gemeinde, they were told that with tolerances for turning, access etc there would only be 3 spaces allowed.
If this is a public parking place, where they allow other cars to park - then there are prescribed dimensions for each space, access, turning spaces, etc.
If this is their property and their cars, they can park all the functioning & maintained cars they want. Heck, they could double stack the cars if they wanted.
What they need to do is abide by the right of access (though note, many times these are for pedestrian access, it's not guaranteed that it's for vehicular access), and abide by safety rules (so if double stacking cars, these cannot leak oil/fuel, etc).
Similarly, they cannot turn their driveway into a car scrapyard with pieces of broken cars leaking fluids and whatnot... but that doesn't sound the case here.
The easiest way to get a definitive answer would be to ask your commune/gemeinde.
What does theirs say?
This is the legal document which should state a right to drive over a particular area. This can also cover things like a footpath, drains, etc.
In Aargau you can look up ownership online, but a right of way/access is not online. A right of way is valid whether someone owns or their property is tenanted.
That being said, because it costs money to add and make changes to the land registry, sometimes owners just don't do it and they have an agreement, sometimes a letter, sometimes a verbal understanding. In some cases people have for years "tolerated" situations which were never in writing.
Then the ownership changes, or new tenants move in, and the problems begin.
Safety and aesthetics are two different things. We have a huge driveway. Could I park a motorhome or a boat on a trailer in it full time? Probably. Unless there is some rule against it which I am not aware of. You need to check with with local authorities if there are restrictions as to the type of vehicles which can be parked on a private driveway. There may be some restrictions.
Hope you can find a solution.

Moreover, the answer may depend on the individual building permit, and as such on its age as the applicable regulations are bound to change over time.
In other words, OP, ask your municipality. While you're at it you may want to make sure that your neighbor's type of use of the estate is permitted. Using it for business purposes in a purely residential area, for instance, might be problematic, subject to the details of course.

Those limits are for parking lots. Not for private land.
So, I could (arguably) build a house with 3 apartments and 3 parking spaces (official). Nothing would stop me using the garden to park another 5 cars.
