Yountville, California Zoning Map

The H district (4 acres) covers the most historically significant portion of downtown Yountville and applies design review standards that govern facade materials, window proportions, signage, and streetscape elements. Any exterior modification to a building within H typically requires approval from the town's design review body. Developers proposing infill within the historic district should engage a preservation architect early and budget for an iterative review process - approval timelines in historic districts are longer than for standard commercial projects.

Yountville's hospitality industry is largely accommodated within the Primary Commercial (PC), Old Town Commercial (OTC), and Planned Development (PD) zones, which together cover only about 20 acres. New hotel or inn development is possible but requires demonstrating consistency with the general plan and passing design review. Given the town's reputation for tightly managed growth, large-scale hotel additions or new hospitality buildings typically face significant community and planning commission scrutiny.

Agricultural (A, 61 acres) is the largest zone in town and is designated for viticulture and farming consistent with the Napa Valley's agricultural preservation mandate. This land is not available for residential or commercial development under normal circumstances - conversion would require a general plan amendment and likely trigger review under Napa County's agricultural preservation policies, which apply even within incorporated town limits. Investors should view A-zoned land in Yountville as permanently committed to vineyards or farming.

Mixed Residential (MR, 4.4 acres) and Master Planned Residential (MPR, 6.1 acres) are the primary residential platforms, supplemented by a small Single Family Residential (RS, 2.2 acres) zone and a Mobile Home Park (MHP, 3 acres). California ADU law requires the town to permit ADUs on qualifying residential parcels, providing a modest avenue for housing unit additions. Given the very small residential acreage, most housing production in Yountville comes from infill within existing neighborhoods rather than new subdivision.

RSC (0.5 acres) is a small district designed to permit low-intensity commercial uses - professional offices, personal services, or small retail - in buildings that match the scale and form of surrounding residential structures. This zone is typically applied at the transition between the commercial core and residential neighborhoods to allow commercial use without the visual or traffic impact of a standard commercial building. Projects in RSC must conform to residential-compatible design standards that distinguish them from the town's more active commercial zones.
