Raleigh R-4: Residential-4 Zoning District Guide
The R-4: Residential-4 district in the City of Raleigh is a residential zone primarily designed for single-unit living on minimum lot sizes of 10,000 square feet. While it maintains a low-density character, the Raleigh R-4 district permits two-unit living in attached houses or tiny houses and offers higher density options through compact development, conservation development, or proximity to frequent transit areas [Sec. 2.1.1.D].
Purpose and General Character
The primary intent of the R-4 district is to protect established residential neighborhoods while promoting planned and efficient future growth within the City of Raleigh. The Raleigh R-4 district is characterized by a "conventional" development pattern where most property owners have substantial private yards [Sec. 2.1.2.A].
However, the R-4 district also serves as a flexible zone that allows for alternative housing patterns. For instance, Raleigh permits "Compact Development" in R-4 to reduce lot sizes in exchange for increased common open space, and "Conservation Development" to protect natural features and scenic vistas [Sec. 2.1.1.D]. In specific "Frequent Transit Areas" identified in the Raleigh Comprehensive Plan, the R-4 district standards may be modified to allow for even smaller lot dimensions to support transit-oriented growth [Sec. 2.1.1.D].
