Urban Dead: Locked Out

One of the things I hate when playing as a human is when I use a strongly barricaded building as a means to get out and hunt some zombies, and when I try to use that building to get back in, it's been barricaded to heavy.

I then either have to attack the barricades or look for other ways to get in, or, if I don't have enough action points, just wait until I'm killed and go to a revive point.
