Grass Valley C-3: Heavy Commercial Zoning District Guide
The Grass Valley C-3: Heavy Commercial zoning district is established to accommodate high-intensity, auto-oriented commercial activities that are typically inappropriate for the downtown core or smaller-scale community business areas. Key development standards for this district include a maximum building height of 50 feet (up to four stories) and a maximum residential density of 15 units per acre for projects incorporating a residential component [Section 17.24.040, Table 2-11].
Purpose and General Character
The City of Grass Valley applies the C-3: Heavy Commercial district to areas intended for heavier retail and service uses. The primary objective is to provide space for businesses that require significant site area or produce impacts (such as noise or high traffic) that are not compatible with the historical Town Core (TC) or the Central Business District (C-2) [Section 17.24.020].
The character of the C-3 district is fundamentally auto-oriented and commercial in nature. While residential uses are permitted as part of mixed-use developments, the district is prioritized for manufacturing, warehousing, and large-scale retail operations that implement the commercial land use designations of the Grass Valley General Plan [Section 17.24.020].
Development Standards
Development within the C-3: Heavy Commercial district must comply with specific requirements regarding lot size, setbacks, and building form to ensure compatibility with adjacent zones, particularly residential areas.

| Maximum Residential Density | 15 units per acre [Table 2-11] |

| Side Setback (Street) | None required [Table 2-11] |
| Rear Setback | 25 feet if abutting residential; 12 feet where loading is proposed; 15 feet elsewhere [Table 2-11] |
| Site Coverage | No limitation other than as required for landscaping [Table 2-11] |

Off-Street Parking Requirements
Parking in the C-3: Heavy Commercial district is calculated based on the specific use of the property. The Grass Valley City Council discourages excessive parking to prevent inefficient land use and excess stormwater runoff [Section 17.36.040].

|---|---|
| General Retail | 1 space for each 250 sf of floor area, plus 1 space for each 300 sf of outdoor sales area [Table 3-3] |
| Office (Business/Service) | 1 space for each 250 sf of floor area [Table 3-3] |
| Warehouse | 1 space for each 500 sf of floor area [Table 3-3] |
| Medical Clinic/Doctor Office | 1 space for each 250 sf of floor area or 4 spaces per doctor (whichever is greater) [Table 3-3] |
| Restaurant/Cafe | 1 space for each 60 sf of dining area [Table 3-3] |
Special District Regulations
- Mixed-Use Projects: Residential units in the C-3 district are typically located above nonresidential uses. These projects must provide for internal compatibility between the residential and commercial components, including minimized noise and glare [Section 17.44.140].
- Loading Areas: Nonresidential uses in the C-3 zone must provide off-street loading spaces. For structures over 50,000 square feet, at least two loading spaces are required [Table 3-8].
- Screening: Any commercial use in the C-3 district adjacent to a residential zone must provide screening, typically consisting of a solid masonry wall six to eight feet in height and a five-foot-wide landscaping strip [Section 17.30.040].
