Petruccelli says; Erect a fence. Even a 3-foot
fence helps create a psychological boundary that helps in deterring intruders,
says Sgt. Dan. “It says, ‘This is my house, my property.’ People are
going to be reluctant to step over that fence.” Higher fences may be
appropriate in high-threat neighborhoods. Before building a fence, check with
your city or county planning office. Most require a permit and many restrict
the height and even building materials.
