Whether or not the fence you are planning to build around your commercial property needs a permit depends on several factors – here are some:

• Zoning – if your commercial facility is located in a residential area, you are likely to be required to obtain a permit for your new fence and you will probably need to comply with the neighborhood’s HOA covenants as well. Commercial zones are more relaxed in this respect;
• The height of the fence – how tall your proposed fence also determines whether it requires a permit. Many neighborhoods allow fences under a certain height to be built without having to take out a permit for it. If you need a permit, be prepared that commercial fence permits usually allow the height of 6-7 feet, a fence that is taller than that can also be authorized, but it takes lots of time and paperwork;
• The material of the fence – in most cases, the commercial fences made from concrete or masonry need a permit.

Thornton gate and fencing regulations may vary widely, depending on the city, the town or the neighborhood, so you can find out whether or not you will need a permit only if you consult the applicable regulations. If your property is surrounded by a fence that you want to dispose of, find out whether you need a demolition permit as well.
