What do you do with lazy neighbors?

[Tresbn00]

I live in a somewhat affluent neighborhood.  I purchased my house while it had great neighbors.  One set of neighbors has moved and rents the house out on two year leases.  The current neighbors rarely cut their lawn, never take in their garbage containers, leave empty flower pots all over their driveway and park their cars outside their three car garage because the garage bays are filled with their boxed up belongings.  They have been there three months.  I mean seriously...have some respect.

 You could always call code enforcement. Here they are so strict that one little infraction and you get fines and liens like nobodies business.
Another plan of attack is if you have a community HOA (Homeowners Association.) Ours broke up a while ago but it was because of the code enforcement became so fierce.
