Zoning: Before you invest in a wind plant, it is a wise idea to make friends with your local building inspector, board of supervisors or planning board. You'll need to check with them to see if a building permit is required for your wind plant. Some areas restrict the height of structures permitted in residentially zoned areas, although variances are often obtainable.
