I'm not sure what it can mean to respect people's property rights with respect to residential-only zoning. A zoning decision is not written into the original deed and can be changed with an exception by the zoning board or a general change in the city/county code. However, the residential-only zoning makes it difficult for one person to use their property as they see fit, for example, building a duplex or rentable apartment onto their house, or opening a small store or tiny school.
