Part 10A: Unified Development Ordinance City of Raleigh, North Carolina 2 – 3 Effective Date: March 6, 2018 Supp. No. 5 Article 2.1. General Provisions | CHAPTER 2. RESIDENTIAL DISTRICTS Sec. 2.1.2. Housing Options Sec. 2.1.2. Housing Options A. Conventional Development Option (see Article 2.2. Conventional Development Option ) 1. Conventional is a pattern of residential development that provides a majority of property owners with substantial yards on their own property. 2. Under the conventional option no preserved common open space is required and the minimum lot size is limited to the lot size for the respective district. B. Compact Development Option (see Article 2.3. Compact Development ) 1. A compact development permits a reduction in lot size for residential subdivisions in exchange for an increase in common open space. This allows for efficient residential subdivisions and ample amenity area for the residents. 2. Size thresholds are district-based and are listed in Sec. 2.3.1. For projects under these minimum size thresholds, only the conventional option can be used. 3. Density is regulated by the zoning district. Where the Conservation Development Option permits additional density, the Compact Development option does not. 4. Applicants that choose the Compact Development option must set aside 20% of the total project area as common open space. Requirements for the configuration, use and management of common open space are set forth in Article 2.5. Common Open Space Requirements. C. Conservation Development Option (see Article 2.4. Conservation Development Option ) 1. A conservation development trades smaller lot sizes (with reduced setbacks) and additional density in exchange for preserving common open space. This allows for more efficient layout of lots, streets and utilities, promotes a mix of housing and protects the natural character of an area through the preservation of open space, recreation areas, environmental features and scenic vistas. 2. A conservation development must be a minimum size to ensure sufficient common open space can be incorporated into the subdivision design. 3. Size thresholds are district-based and are listed in Sec. 2.4.1. For projects under these minimum size thresholds, only the conventional option can be used. 4. Applicants that choose to use the conservation development option must set aside 40% of the total project area as common open space. Requirements for the configuration, use and management of common open space are set forth in Article 2.5. Common Open Space Requirements. Sec. 2.1.3. Additional Housing Patterns A. Cottage Court (See Sec. 2.6.1. ) A cottage court is a group of small detached houses centered around a common open space or courtyard. The central court enhances the character of the area through the provision of consolidated open space. B. Detached House Conversions (See Sec. 2.6.2. ) A detached house addition is when an existing detached structure is expanded and converted into an attached building or apartment building. Additional regulations are required for these conversions.
