How long does a landlord have before they can throw away your stuff and tow your cars?

Question Details:

I was living at an apartment for about a year. We moved out a month or so early and attempted to negotiate a deal with the landlord. We had 2cars and some heirlooms left in the house for a couple weeks after we moved out. We went by the house a few days ago to find the cars gone and the heirlooms taken. The landlord will not answer phone calls, and we've left many voicemails to no avail. I'm just wondering if it's legal for him to do this without notice and then ignore the phone calls to get our things back? He never filed an eviction notice. Any documents I can take to court to help me? Important Notice
