Industrial Mixed Use (IX-) District Setback Requirements in Raleigh
In the City of Raleigh, the IX-: Industrial Mixed Use district features setbacks that vary based on the specific building type being constructed, ranging from as little as 3 feet for general buildings to 10 feet for civic buildings. These base requirements are established to balance industrial utility with the district's mixed-use character, though they are subject to significant modification if a specific Frontage is assigned to the property or if the site abuts a residential neighborhood. Under the Raleigh Unified Development Ordinance, residential uses in the IX- district are restricted to the upper stories of mixed-use buildings [Section 3.1.1.G].
Allowed Building Types and Setbacks
The Raleigh Unified Development Ordinance permits four specific building types within the IX- district: General Building, Mixed Use Building, Civic Building, and Open Lot. Setbacks for these types are measured from the primary street, side street, side lot lines, and rear lot lines.
Base Dimensional Standards for IX-
The following table outlines the minimum building setbacks for each allowed type within the City of Raleigh IX- district:
| Building Type | Primary Street (min) | Side Street (min) | Side Lot Line (min) | Rear Lot Line (min) | From Alley (min) |
|---|---|---|---|---|---|
| General Building | 3' | 3' | 0' or 6' | 0' or 6' | 5' |
| Mixed Use Building | 5' | 5' | 0' or 6' | 0' or 6' | 5' |
| Civic Building | 10' | 10' | 0' or 6' | 0' or 6' | 5' |
| Open Lot | 10' | 10' | 10' | 10' | 10' |
[Sections 3.2.5, 3.2.6, 3.2.7, 3.2.8]
Parking Setbacks
Vehicular parking within the IX- district must also adhere to specific setback requirements. In most cases, on-site surface and structured parking must be located behind the parking setback line [Section 1.5.5.C].
| Building Type | Primary Street (min) | Side Street (min) | Side Lot Line (min) | Rear Lot Line (min) | From Alley (min) |
|---|---|---|---|---|---|
| General Building | 10' | 10' | 0' or 3' | 0' or 3' | 5' |
| Mixed Use Building | 10' | 10' | 0' or 3' | 0' or 3' | 5' |
| Civic Building | 10' | 10' | 0' or 3' | 0' or 3' | 5' |
| Open Lot | 10' | 10' | 10' | 10' | 10' |
[Sections 3.2.5, 3.2.6, 3.2.7, 3.2.8]
Modifying Factors: Frontages and Transitions
The base setbacks listed above are default standards. The City of Raleigh Unified Development Ordinance specifies two primary scenarios where these standards are overridden.
Frontage Requirements
If an IX- property is designated with a "Frontage" on the Official Zoning Map, those requirements control over the base standards [Section 3.4.1]. For example:
- Parkway (-PK): Increases both building and parking setbacks from the primary street to a minimum of 50 feet [Section 3.4.3].
- Urban Frontages (-UL, -UG, -SH): These frontages often implement "Build-to" ranges rather than simple setbacks, requiring a percentage of the building facade to be located very close to the street (e.g., within 0' to 20' for Urban Limited) [Sections 3.4.7, 3.4.8, 3.4.9].
Neighborhood Transitions
When an IX- district site immediately abuts a residential district boundary (R-1, R-2, R-4, R-6, or R-10), Neighborhood Transition standards apply to protect the residential character [Section 3.5.1].
- Zone A (Protective Yard): Requires a vegetative buffer and a wall or fence immediately abutting the district boundary. No buildings or structures are allowed in this zone [Section 3.5.2].
- Zone B: Extends 50 feet from the district boundary and restricts usage to low-intensity activities like surface parking, landscaping, or service areas [Section 3.5.2].
