Is it legal to park a car in your backyard?
Then, can I park a car in my backyard?
Guess what, it is likely illegal to park in your backyard with a noncommercial vehicle. You can only use your property in the manner allowed by law. Parking vehicles, of any kind, which can pose a hazzard or danger (to your neighbors), in your backyard is normally not allowed.
Subsequently, one may also ask, what to do if a car is parked on private property?
If a car is parked on your property without your permission, first, see if you can find out whose car it is and ask them to move it. If you can't find the person, call the police. They can trace the car's owner through the tag and it can be ticketed and towed as being abandoned on private property.
If a vehicle is not infringing any local parking regulations, there is no general prohibition on parking in residential roads except in relation to HGVs. In the legislation they are referred to as 'heavy commercial vehicles' and are defined as “any goods vehicle which has an operating weight exceeding 7.5 tonnes”.
