Answer
You can access the california code on the web through DMV. It will provide you with all of the regulations for towing. If you own the property and you have the proper signs posted you can have the vehicles towed. You need to make sure you are within the requirements for your state because you can be held liable if you do not meet the requirements. I would consider posting notices on all of the vehicles informing them they will be towed. Take photographs and keep a description of the vehicles including tag numbers. Then just go from there. If they are blocking access the PD needs to be notified.
