Residential-30 (R-30) Legacy Zoning in the City of Raleigh
The R-30 (Residential-30) designation is classified as a "Legacy District" within the City of Raleigh Unified Development Ordinance, meaning it belongs to the older Part 10 Zoning Code and is slated for eventual replacement by modern UDO districts [Section 1.3.4]. Under current City of Raleigh regulations, no new R-30 districts may be added to the Official Zoning Map, and the boundaries of existing R-30 districts cannot be modified [Section 1.3.4].
Administrative Status of R-30 in Raleigh
The City of Raleigh identifies R-30 as a district that exists within the previous zoning framework. While these districts remain in effect for properties currently zoned as such, they are being phased out in favor of UDO residential districts like R-1, R-2, R-4, R-6, and R-10 [Section 1.3.4].
Classification as a Legacy District
The City of Raleigh Unified Development Ordinance lists several residential legacy districts that are no longer available for new zoning applications.
| Legacy District Name | UDO Reference | Status |
|---|---|---|
| R-15 | Residential-15 | Legacy |
| R-20 | Residential-20 | Legacy |
| R-30 | Residential-30 | Legacy |
| SpR-30 | Special Residential-30 | Legacy |
| RB | Residential Business | Legacy |
[Section 1.3.4]
Rules of Interpretation for Legacy Districts
Because R-30 is a legacy district, the City of Raleigh applies specific rules when conflicts arise between old zoning conditions and new UDO standards:
- UDO Dominance: If a property has an approved legacy zoning condition that conflicts with the corresponding new UDO general use district, the new UDO district standards generally control the development [Section 1.2.3.A].
- Stringency Rule: UDO regulations regarding height, setback, parking, landscaping, and screening take precedence over legacy district ordinances if the UDO standards are more stringent [Section 1.2.3.B].
- Use Limitations: If a conditional zoning ordinance limits a property to uses allowed in the legacy R-30 district, those limitations continue. However, if a use allowed under the old R-30 rules is explicitly prohibited in the new UDO general use district, the UDO prohibition takes precedence [Section 1.2.3.D].
Development Standards for R-30 Properties
Properties in the City of Raleigh governed by "other" base zoning districts (including legacy districts like R-30) must adhere to specific environmental and site standards established in the UDO.
Impervious Surface Limitations
The City of Raleigh regulates the maximum percentage of a lot that can be covered by impervious surfaces (such as roofs, driveways, and sidewalks) to manage stormwater runoff.
| Zoning District | Maximum Percentage of Impervious Surface Coverage |
|---|---|
| R-1 | 20% |
| R-2 | 25% |
| R-4 | 38% |
| R-6 | 51% |
| R-10 and all other base zoning districts | 65% |
[Section 9.2.2.A.4]
Tree Conservation Requirements
For any development or subdivision in the City of Raleigh on a tract of 2 acres or greater, tree conservation is required. While R-1 and R-2 districts require 15%, the R-30 designation falls under the category of "All other districts," which requires a minimum of 10% of the net site area to be set aside for tree conservation [Section 9.1.3.A].
Prohibited Uses and Violations
The City of Raleigh maintains a strict policy regarding allowed uses to protect the character of residential areas.
- Non-Residential Use Prohibitions: In the City of Raleigh, any use of a "prima fascia business, commercial, or industrial character" is prohibited if it is not specifically allowed in the residential district use tables [Section 6.1.5.A].
- Signage Prohibitions: Signs not explicitly authorized by the UDO or the original legacy ordinance are prohibited. Any sign that has been abandoned for more than one year must be removed by the owner [Section 7.3.15.L].
- General Prohibition: Except for improvements made via approved site plans, any use not explicitly allowed as a permitted, limited, or special use is prohibited in the City of Raleigh [Section 6.1.5].
