Residential Site Restrictions
For residential projects in the R-4 district, the City of Raleigh imposes physical limits on where and how parking can be situated on a lot to maintain neighborhood character.
Front Yard Coverage
For any detached house, tiny house, or attached house in the R-4 district used for residential purposes, the combined area of all parking and driveways cannot exceed 40% of the total area between the front building facade and the front property line. Additionally, any parking located in the front setback must be deep enough to ensure parked vehicles do not encroach upon the adjacent sidewalk [Sec. 1.5.5.D].
Parking Surface Standards
All off-street parking and driveways must be constructed of permanent, non-erodible materials. Permitted surfaces include:
- Poured concrete or asphalt.
- Masonry or concrete pavers.
- Porous or semi-porous monolithic or paver materials.
- Crushed stone or "crush and run," provided it is at least 4 inches deep and delineated with anchored edging materials to contain the stone [Sec. 7.1.9].
Specific Parking Setbacks for R-4
Parking areas must adhere to minimum setbacks from property lines. These requirements vary depending on whether the project follows conventional standards or the Frequent Transit Development Option.
