City of Grass Valley Fence and Wall Height Standards
In the City of Grass Valley, the standard maximum height for a fence or wall located within an interior side or rear setback is six feet. This height may be increased to a maximum of eight feet if the portion above six feet is an open fencing design, such as lattice or wrought iron, or if a Minor Use Permit is granted for a solid fence. Fences located within the front or street-side setbacks are more strictly limited to a maximum height of 36 inches to maintain visibility and neighborhood character.
General Fence Height Requirements
According to the Grass Valley Development Code, maximum fence heights are determined by their specific location on a parcel relative to required setbacks. These standards apply to all fences and walls unless a specific zoning district or use provides an alternative regulation [Section 17.30.040.A].
Maximum Height Standards
The following table outlines the height limitations for fences and walls throughout the City of Grass Valley:
| Location of Fence or Wall | Maximum Allowed Height |
|---|---|
| Within front or street side setback | 36 inches |
| Within interior side or rear setback | 6 feet (1) |
| Outside of a required setback | 6 feet (1) |
(1) Height Exceptions: A fence or wall may reach up to eight feet in height if the portions above six feet consist of an open fencing design (e.g., lattice, wrought iron, or grille work). Additionally, a solid fence up to eight feet may be authorized through the approval of a Minor Use Permit [Table 3-2].
Height Standards in Specialized Districts
Certain districts within the City of Grass Valley have unique requirements that may supersede or add to the general standards, particularly regarding the "Build-to-Line" (BTL) or specific industrial needs.
- Traditional Community Development Zones: In districts such as the Town Core (TC), Neighborhood Center (NC), and Neighborhood General (NG) zones, any section along a Build-to-Line not defined by a building must often be defined by a fence or wall of a specific height, typically ranging from 2 feet, 6 inches to 6 feet depending on the specific zone [Section 17.21.040, 17.21.050].
- Southeast Industrial District (SEID): In this specific combining zone, eight-foot chain-link fencing is expressly allowed. Furthermore, "bunker walls" located on frontages in the SEID are permitted to reach a maximum height of eight feet [Section 17.28.080.C.2.b].
Measurement and Safety Regulations
The City of Grass Valley requires specific methods for measuring height and prohibits certain materials to ensure public safety.
Measurement of Height
Fence and wall height is measured as the vertical distance between the finished grade at the base of the fence and the top edge of the fence material [Section 17.30.040.C]. For retaining walls on embankments in multi-unit residential or nonresidential projects, if a wall exceeds six feet in height, it must be benched so that no individual wall exceeds six feet, with each bench having a minimum width of 36 inches [Section 17.30.040.D.3].
Prohibited Materials
The following materials are prohibited for use in fencing within the City of Grass Valley unless required by state or federal law:
- Razor or concertina wire (either by itself or on a fence/wall) when located within a front or street side setback.
- Barbed wire or electrified fences, except when approved by the Director for the purpose of animal control [Section 17.30.040.E].
Screening Requirements Between Different Land Uses
When a commercial or industrial land use in Grass Valley is proposed adjacent to a residential zone that allows single dwellings, a screening wall is required at the parcel boundary. This screen must consist of a solid, decorative masonry wall or similar durable material six feet in height (up to eight feet may be allowed per general height exceptions). This wall must be architecturally treated on both sides [Section 17.30.040.F.1].
