Yes. If you are building a privacy fence, regardless of whether you are doing it yourself or hiring a professional service, you need to find out what your zoning codes are and check the HOA regulations of your city. In some cases, privacy fences are not allowed in your area, and if they are, they might have a height limit or other restrictions. If you aren’t sure, go to your city government and check if fencing is allowed in your area and if a fence-building permit is necessary.
