Unsafe areas are north east of Marietta Square to I-75, South of Marietta to Sandtown, west of tracks not so good, (South, but east of train tracks is ok.) Don't consider apartments on Franklin Road.verything else is good to very good to excellent for safety and quality of homes. NW of the square, 1/4 mile out, is high dollar, but very safe, East of Marietta (east of I-75) is very safe, West of Marietta out to Paulding County line is very safe.
