Residential Zoning Districts
Overview
There are a variety of residential zoning districts offering a wide range of housing types, lot sizes, and densities. These include SR (Single-Household Residential), SM (Single-Household/Manufactured Home Residential), and MR (Multiple-Household Residential). TR (Transitional Residential) districts are subject to the requirements of the similar Residential Zoning District, for example, TR-8 is treated the same as SR-8. As the name implies, TR districts are located at the fringes of developed areas and act as a transition zone between high-density urban and low-density rural lands.
