if the zombies are following him/her anyway, then they're going to try and get in, whether you open the door to the person or not. Unless the person gives up, run further down the street and starts banging and shouting at another door, which draws their attention, and hope no zombies bang into your place. Also hope the person doesn't think your place is abandoned, and tries to force their way in somehow to escape.
Obviously you'd have made a way to see outside, without anyone being able to see in. Shut them up quickly, any way.
You can run to the back, load a home made bomb or something into your hand made catapult, fire it. Then hope that is enough to draw the zombies away, again without any of them passing through your area, and possibly stumbling into your building.
