Hello there, I was hoping to get some input from the experts about a fence I'm going to do DIY on. I need to put a fence on my house to keep my neighbors renters from walking up the driveway. These are weekly renters during the summer, so they don't seem to be very respectful of my property. These are 50x100 lots, so there isn't much space for people to walk on their own property to get to the backyard. I've spoken to the owner, but they don't see that it is a problem. Our driveway is right against this property line, so even if we have cars there, they will be walking on our driveway(with boogie boards, and beach chairs) and against our cars to get to their back gate. It has been a frustration for me the whole summer. I will just need a 36 foot fence to extend form their back fence, to the front sidewalk. Question 1: I'm going to put up a wood fence with a shadow box affect, but I want to make sure that I'm selecting a sturdy fence. Any concerns about that? I can't do chain link because that is not approved for the area, and I don't think that Vinyl is as strong as wood. Question2: I am putting up a 5 ft tall fence, and I have been grappling with either 4x6 or 6x6 for the posts? The only reason I was thinking 4x6, because they are a little lighter to work with, as I'm trying to set them in the ground? I would prefer 6x6 for the additional strength. I worry that the renters will start resting stuff like bikes, and chairs, coolers, and boogie boards on their side of my fence. Any thoughts?
