Allowed and Prohibited Land Uses in the TC: Town Core Zone of Grass Valley
In the TC: Town Core zoning district, the City of Grass Valley prioritizes a pedestrian-oriented, mixed-use environment where retail, dining, and professional offices are largely permitted by right, though ground-floor residential use is restricted on major historic corridors. While most commercial activities are encouraged, the Grass Valley Development Code strictly prohibits all medical marijuana cultivation and dispensaries throughout the district, and requires a Use Permit for high-intensity operations like nightclubs or retail spaces exceeding 10,000 square feet.
Purpose of the TC: Town Core Zone
The primary intent of the TC: Town Core district is to strengthen the historic, pedestrian-oriented nature of downtown Grass Valley while establishing secondary mixed-use centers within regional districts likely to redevelop. The zone is characterized by compact development, workforce housing opportunities, and a requirement for shopfront-related frontage types with ground-floor commercial uses [Section 17.21.030].
