Replacing backyard fence - questions about permits (Phoenix: house, closing)

[Robert A]

I live in Phoenix. Here's my problem.

The storm a week back knocked down a wooden privacy fence in my backyard completely. The fence and posts are rotted and beyond repair. It needs to be replaced.

The home next door is vacant. Another neighbor told us they're foreclosing. At any rate, they haven't been there for months and we have no way of getting a hold of them.

I'm assuming the fence is/was on the property line but obviously can't get a neighbor's consent to erect a new fence on that line. I need this replaced ASAP because I don't want to look into their gross, overgrown backyard anymore.

We bought posts and put a couple in and then I thought "Hey! Maybe I need permits for this!" Do I? Will I be able to get permission from the city to build it on the property line? Either the posts or planks will cross the property line slightly - the previous owner of my house had the brilliant idea to lay concrete on the side of the home all the way up to the line.

Please help!
