Take a look at the zoning descriptions. If the property is located withing the city limits, use the zoning code for that city. If its located in the county, use their code. The best way to find it is to simply go to that city's/county's website and search for it. It will usually be in a PDF that gets downloaded, and in it will be a description of the uses, and building codes.
Hope that helps!
