If you own a commercial building on your own lot, you'll be responsible for your own security. You may want to put a fence around your property to keep the building secure at night. If you offer professional services, you might want an upscale fence. However, if you have an operation such as a retail shop, laundromat, or repair business, a chain link fence might be a good choice.
