Commercial Real Estate in Benicia: Industrial Park, Port, Historic Districts and Mixed Use

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

Benicia’s commercial property falls into three very different settings: a large industrial area on the city’s east side that includes the Valero refinery, the Port of Benicia and the Benicia Industrial Park; the historic downtown along First Street and the old Benicia Arsenal, where preservation rules shape every project; and commercial and mixed-use corridors serving the neighborhoods. Each runs under its own chapter of the city’s zoning code. Confirm the district, any historic overlay and any master plan for each parcel with Benicia’s Community Development Department before relying on this page.

Who controls the parcel

Benicia is an incorporated city, and Title 17 of the Benicia Municipal Code sets zoning through base districts plus overlay districts for historic resources (H), hillsides, the shoreline, neighborhood conservation, housing opportunity sites, interim study areas and master plans. Most district chapters date from Ordinance 87-4 N.S. in 1987 and were updated by Ordinances 25-09 and 25-12 in 2025. Waterfront parcels may also need regional shoreline review. For unincorporated land nearby, see our Solano County commercial guide.

Benicia zoning for commercial, industrial and mixed use

The industrial area, refinery and port

Benicia’s industrial chapter protects industrial land from retail and from conversion of prime sites to general office use.

• Refining and port uses. In IG, general industry is permitted, but oil and gas refining needs a use permit. Port terminals are allowed only in IW, which is reserved for port-priority and water-related uses.
• Technology uses. All four districts encourage biotech, clean tech and laboratory users, though vivarium facilities are prohibited.
• Food and drink. Restaurants are allowed as secondary uses up to 2,500 square feet, need a use permit to 5,000 and are barred above that. Bars are not permitted, and food sales in IL and IG are capped at 1,000 square feet without a use permit.
• Offices. General offices are allowed only in IP, and even there medical, dental, insurance and real estate brokerage offices are excluded.
• Cannabis. Cannabis retail is barred in every industrial district, while cultivation, distribution, manufacturing, testing and delivery-only operations need a use permit.
• Height. IG and IW list no height limit, which suits tanks and process equipment.

A buyer of an industrial park building should check the refinery’s current status and any city planning for the area, since major changes there could affect neighboring parcels.

Historic districts, the Arsenal and downtown

Benicia’s historic core is covered by the H Historic Overlay, whose purposes include deterring demolition or neglect of historic buildings and guiding change through a conservation plan for each district.

• Permits. No building permit for construction, alteration, enlargement or demolition can issue in an H district without prior approval from the development services director or the Historic Preservation Review Commission. New work must be found compatible with the district.
• Demolition. Demolishing a historic structure needs commission approval. If it finds historic or cultural value, the commission can delay approval for 180 days or until environmental review is done, whichever is later.
• Upkeep. Owners must keep exteriors in good repair, and hardship relief can allow conditions to be met over up to five years.
• Arsenal. The commercial chapter allows residential projects in the Arsenal historic district a higher maximum FAR of 2.0, against 1.2 elsewhere in commercial districts.
• Shoreline heights. West of First Street, within 150 feet of the shoreline, residential-district buildings are held to 24 feet and two stories.

Downtown projects may also fall under a master plan overlay (Chapter 17.68); confirm which plan applies to a First Street parcel.

Mixed-use corridors

The MU-I district aims for a pedestrian-friendly street frontage and a commercial critical mass, and requires a use permit for some ground-floor housing on Military East and East Fifth Street. Mapped ground-floor street-facing offices need a use permit unless an office occupied the space on February 17, 2022, and single-tenant commercial spaces over 3,000 square feet need one too. MU-L caps commercial space at the lesser of 50% of residential floor area or 2,000 square feet. In the commercial districts, housing is generally limited to upper floors, cannabis retail can be approved by use permit in CC, CG and CW, and every project needs development plan review.

Transfer tax, business tax and property tax

Benicia’s Chapter 3.16 sets $0.275 per $500 on transfers over $100, administered by the County Recorder. The Solano County documentary transfer tax is $0.55 per $500 under Solano County Code Section 11-60, and Section 11-67 credits a city tax adopted under the same state law at half the county rate, so Benicia’s tax is shared within the county amount rather than added; confirm the total in escrow. Business license tax rates are in Chapter 5.06 and hotel tax in Chapter 3.24; we did not verify rates. A change of ownership generally triggers Proposition 13 reassessment.

Due diligence that matters in Benicia

Start with our commercial due diligence checklist, then add:

• Confirm the district and whether an H, shoreline or master plan overlay applies.
• In industrial districts, check office limits; outside IP, general offices are not allowed.
• For a restaurant in an industrial building, confirm the 2,500 and 5,000 square foot thresholds.
• For historic buildings, plan for commission review of exterior changes and possible demolition delays.
• Check the refinery’s status and any hazard or buffer studies for nearby parcels.
• For port-related users, confirm the parcel is IW.
