According to me yes they can because the landlord has right to this.
If this issue is not addressed directly in your lease, state laws vary on what a landlord is required to do with such property after an eviction process has been legally effected.
As indicated by these answers, people have conflicting opinions about what a landlord is able to do.
That's why the states have laws that deal with such contingencies---the states determine what rights and procedures the tenants and landlord must follow.
Long story short, I was illegally evicted and I am taking it to court.
The point is, I have 30 seconds to grab my things. The complex refuses to speak with me, and I have no idea how long they will hold my things.
I am not a lawyer but here is some advice for you:
1. If you are having financial trouble, call your landlord and explain the situation to them, BEFORE, your rent is late. Ask for extra time, or payment arrangements. If they work with you, keep to your payment arrangements. Note: Because of your lease, the landlord does NOT have to help you out. A landlord is more likely to work with you if you call them before the rent is late than after.
2. If you get a Notice to appear in court, go to the hearing, even if you pay. Explain to the judge your situation and you may not get evicted. Everytime you get taken to court by the landlord, you will have a judgment entered against you even if you pay. This effects your credit. You will have a very difficult time renting another apartment anywhere with judgements on your report.
3. If you are evicted, you will know at least a month before. A landlord must; Personally serve you the summons for the eviction hearing, AND the the eviction notice. Most will tape this notice to your door if you aren't home or don't answer the door. To avoid being put out, Move out before the date of your eviction! Don't wait. Do what ever you have to to get out. Sell your stuff, if you have to, but if they put you out, you'll likely lose all your possessions anyway.
4. A landlord is NOT allowed to engage in "Self Help" evictions. They cannot evict you, for any reason without a court order. If they provide utilities(water, heat, electricity), they cannot turn them off.
5. READ YOUR LEASE! READ YOUR LEASE! Read your lease. The lease is a contract between your landlord and you. Some leases give you leeway in dealing with a landlord. Some give you none at all. (ex.) If you are one day late, even one time, you can be evicted if the lease states that.
