Grass Valley R-2A Medium Density Residential Setback Guide
In the City of Grass Valley, the R-2A: Medium Density Residential district requires a 15-foot front setback for primary building facades and a 5-foot setback for interior side property lines. Corner lots in the R-2A district must maintain a street-side setback equal to 20% of the lot width (up to a maximum of 15 feet), while the provided development standards notably list no specific requirement (N/A) for rear setbacks in this zone.
R-2A District Development Standards
The following standards apply to all new construction and additions within the R-2A: Medium Density Residential district of Grass Valley. These requirements ensure consistent neighborhood character and adequate separation between structures [Section 17.22.040].
| Development Feature | R-2A District Requirement |
|---|---|
| Front Setback (Building Facade) | 15 feet (or average of adjacent dwellings) |
| Front Setback (Front Porch) | 5 feet |
| Side Setback (Interior) | 5 feet |
| Side Setback (Street Side) | 20% of lot width (maximum 15 feet) |
| Rear Setback | No requirement specified (N/A) |
| Garage Front Setback | 5 feet behind the street-facing facade of the primary structure |
Primary Front Setback Calculations
The City of Grass Valley allows for flexibility in the 15-foot front setback requirement for the R-2A district based on existing neighborhood conditions. The required setback may be determined by:
- Averaging: The average of the front setbacks of the two adjacent primary dwellings.
- Single-Sided: If only one adjacent lot is developed, the new structure may use the same setback as that adjacent primary dwelling.
- Porch Exception: Front porches are permitted to extend closer to the street, requiring only a 5-foot setback from the front property line [Table 2-9].
Side and Street Side Requirements
While interior side property lines require a standard 5-foot separation, corner lots are subject to more variable rules to maintain visibility and neighborhood aesthetics. The street-side setback for an R-2A corner lot is calculated as 20% of the total lot width. However, this requirement is capped and will never exceed 15 feet [Table 2-9].
Allowed Encroachments into Setbacks
Certain architectural features are permitted to project into the required setbacks in the R-2A district, provided they do not come closer than 36 inches to any side or rear property line [Section 17.30.030].
| Projecting Feature | Allowed Projection into Front/Street Side | Allowed Projection into Side | Allowed Projection into Rear |
|---|---|---|---|
| Uncovered Decks/Landings (<30" high) | 25% of setback (max 5 ft) | To property line | To property line |
| Roofed/Unenclosed Balconies | 25% of setback (max 5 ft) | 20% of side setback | 20% of setback |
| Bay Windows | 36 inches | 20% of setback | 36 inches |
| Chimneys/Fireplaces | 24 inches | 24 inches | 24 inches |
| Cornices, Eaves, Overhangs | 24 inches | 30 inches | 5 feet |
