Thomas - most towns have regulations as to the grass height and such. It's mostly a matter of crowded your area is, as to if you are likely to have neighbors complaints. It sounds like you just need a bit more rural that urban area. Many parts of Howell, Millstone and Farmingdale still have that touch of former country space. Jackson, Wall, Upper Freehold and Imlaystown may also be good choices, as well, depending on all the criteria you need to meet.
Hope this helps. Let me know if I can be of further assistance.
