Commercial Real Estate in Napa: Downtown Districts, Oxbow Commercial and Citywide Commercial Zones

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

The City of Napa holds most of the county’s urban commercial land: the downtown core on First and Main Streets, the Oxbow area between Soscol Avenue and the Napa River, neighborhood and community shopping centers, office districts, and industrial land. Its zoning code splits downtown into four districts with their own use rules under the Downtown Specific Plan, while the rest of the city uses citywide commercial, office and industrial zones. Confirm the zone, overlays and any master plan for each parcel with the City of Napa Planning Division before relying on this page.

Who controls the parcel

Inside city limits, the City of Napa’s Title 17 zoning code governs. Its introductory provisions, from Ordinance O2003-12, say the code must implement the General Plan and that the General Plan prevails where the two conflict. Land outside city limits is unincorporated county land under Napa County zoning, so check which side of the boundary a parcel sits on; see our Napa County commercial guide.

Within the city, several layers can stack on a parcel:

• Downtown Specific Plan. Under Section 17.10.040, properties in the plan area follow Section 4.7 of the plan for development standards.
• Overlay districts. These include airport compatibility (AC), building form (BF), affordable housing (AH), entertainment (ED), floodplain management (FP), parking exempt (PE), Soscol Corridor (SC), traffic impact (TI) and water setback (WS), listed in the Title 17 index.
• Master plan districts. Large sites run on their own master plans, including Stanly Ranch Resort, Napa Pipe, Gasser and Old Sonoma Road Mixed Use, and mixed-use districts cover Tannery Bend and the Gateway area.

Napa zoning for commercial, office, industrial and mixed use

FAR and density in CL, CT and CC come from the General Plan rather than the zoning chapter, with calculation rules in Chapter 17.52.

Downtown: First Street, Main Street and the Oxbow

The commercial chapter, as revised by Ordinance O2012-4 on May 15, 2012, maps the downtown districts by street:

• DCC covers First Street from School Street to the Napa River and Main Street from Fifth Street and the Napa Mill to Caymus Street. It is meant to be a walkable shopping and entertainment district that keeps its historic character and adds outdoor gathering space.
• DMU wraps around the core, roughly from Clay and Pearl Streets north to the downtown boundary and from Seminary and Church Streets east to the river and south to Third Street.
• DN sits on the north, south and west edges of downtown.
• OBC covers the eastern part of downtown between Soscol Avenue and the Napa River, north to River Terrace Drive.

Downtown use table. Downtown uses are listed separately for ground level and upper levels in each district. Many uses carry size or hours triggers, such as a use permit once a space exceeds 5,000 square feet or stays open after 10 p.m. The table has been amended repeatedly, most recently by Ordinance O2020-009 on June 23, 2020.

Tasting rooms. Wine tasting is generally allowed with specific standards downtown. It needs a use permit once retail area exceeds 5,000 square feet, and in some columns it is limited to nonresidential buildings existing on May 1, 2012.

Hotels and condo hotels. Hotels need a use permit approved by the City Council in every downtown district, and condo hotels fall under Section 17.52.095.

Vacation rentals. These are conditional with specific standards in each downtown district, under Chapter 17.52.

Citywide commercial rules

Restaurants and bars. In CL, CT and CC, restaurants serving beer or wine are permitted. Food service with a full bar, live entertainment, dancing or a drive-through is conditional and must meet specific standards.

Retail. Shopping centers are permitted in CC and in CL and CT up to 25,000 square feet, beyond which a use permit is needed. Liquor stores are conditional in CL and CT and permitted in CC.

Auto uses. Service stations, car washes and detailing need use permits in CL and CC, and vehicle sales are conditional only in CC.

Setbacks and transitions. Front and street-side setbacks are 30 feet on arterials and collectors and 15 feet on local streets, reducible to 15 feet through design review. Commercial projects next to residential districts must meet transitional standards in Section 17.10.040(E), last amended by Ordinance O2019-001 on January 15, 2019.

Overlays to check. The Entertainment, Parking Exempt and Soscol Corridor overlays change what is allowed or required on affected parcels, and the Floodplain Management and Water Setback overlays matter near the Napa River.

Transfer tax, business tax and property tax

The City of Napa’s real property transfer tax (Chapter 3.16) is $0.275 per $500 of consideration over $100, excluding remaining liens, and the County Recorder administers it. Napa County’s document transfer tax page gives a combined $0.55 per $500 with one-half going to the city, and notes the seller customarily pays in Northern California, so the city tax appears to be the city’s half of that rate. Confirm the total on the escrow estimate.

Title 3 also includes a transient occupancy tax (3.20), a separate transient occupancy special tax for affordable and workforce housing (3.22), a property development excise tax (3.24), a parking and business improvement tax (3.28), an Oxbow Business Improvement Area (3.29) and a downtown parking assessment area (3.30), listed in the Title 3 index. Ask the city which apply to a given property and at what rates; we did not review their text. Business licenses are in Title 5. A sale generally triggers Proposition 13 reassessment.

Due diligence that matters in Napa

Start with our commercial due diligence checklist, then add:

• Confirm the zone and, downtown, whether the use is listed for the ground floor, upper floors or both.
• Check size and hours triggers for restaurants, bars and tasting rooms.
• Read the Downtown Specific Plan’s Section 4.7 standards for downtown parcels.
• Check every overlay, especially floodplain, water setback, airport compatibility and parking exempt.
• For a large site, confirm whether a master plan district controls.
• For hotels, budget time for City Council approval of the use permit.
