Invest in some wheel clamps :D Could become quite profitable :)
On a more serious note, the Rock garden idea should work, it's done all over JHB outside complex's where the lawn is technically Municipality grounds.

We use to have the exact same problems too until we complained to the neighbours about their friends on our lawn. Since then our grass has grown nicely. They also had a habit of parking in front or accross from our garage blocking the door so couldn't turn in etc.
So if you know which place the people are visiting tell the people who they visiting to tell them to park somewhere else or you may fine or tow them away at their expense.
Dont do anything drastic, go the calm, cool and collected route without spiking tires, scraping paint etc.
Currently we got neighbours who speed up the road at 80 - 100km/h where my cats normally stroll and wish I could catch them before they vanish to complain.
Luckily my current cats have had no problems, but one of my cats 2 years ago got hit by a car in same street yet they never contacted me to apologise, although I am tempted to put a speed limit sign for 30-40 or children/animals at play sign up.
You could put a towaway sign or no parking sign in front of your lawn somewhere :D
Get the municipality involved, also double check if it is zoned correctly commercial zones should have sufficient areas to park and it's not up to you to sort it out it's up to the offices that are the issue.
