Summary of Residential Zoning Districts

The City's zoning plan establishes several classes of residential districts to guide and regulate future growth, protect neighborhood character, and ensure orderly development [§ 30 1.2]. The designated general residential districts include R-1, R-2, R-3, R-4, R-5, and R-6, as well as the North Park Street Residential (NP-R) district [§ 30 3.1].

Below is a summary of the specific residential districts detailed in the zoning code.
