Dry hire is the norm in California
You buy the alcohol, the bartender provides service. This avoids the need for a sales license at a private, no-charge event.
Mobile Bartending in San Diego
What bar service costs, the licensing rules people get wrong, and how much alcohol to actually buy.

Quick answer
Mobile bartending in San Diego typically costs $45 to $85 per bartender per hour with a four- or five-hour minimum, or $22 to $55 per guest for a full package that includes mixers, ice, glassware, garnishes, and a portable bar. Most mobile bartenders in California operate dry-hire — you buy the alcohol, they pour it — because selling alcohol requires an ABC license the host or caterer usually holds. If guests pay for drinks in any form, including a ticket or a donation, you need a one-day ABC daily license, filed at least 10 days ahead. Plan one bartender per 50 to 75 guests, or one per 40 if you're serving craft cocktails. For a 100-person event, expect roughly two bartenders for five hours plus a bar setup fee — around $700 to $1,400 in labor and equipment before alcohol, which typically adds another $800 to $2,000 depending on whether you serve beer and wine only or a full bar.

Licensing and liability, plainly
Selling drinks changes everything
Cash bars, drink tickets, or a cover charge that includes alcohol trigger the need for a one-day ABC daily license. File at least 10 days ahead.
RBS certification is required
California requires alcohol servers to hold Responsible Beverage Service certification and be registered with ABC. Ask for the certificate number.
Liquor liability insurance
Ask for a COI with liquor liability, not just general liability. Most venues require $1M and want to be named additional insured.
Venue rules override everything
Many San Diego venues have an approved bartender list or require you to buy alcohol through them. Confirm before hiring.
How much alcohol to buy
Assume one drink per guest per hour
Front-load it: guests drink about two in the first hour, then one per hour after. A five-hour, 100-guest party is roughly 600 drinks.
Standard splits
For a mixed crowd, plan roughly 50 percent beer and seltzer, 30 percent wine, 20 percent spirits, then adjust for your guests.
Yields
A 750ml wine bottle pours five glasses. A 1.75L handle of spirits pours about 39 cocktails. A keg of beer is roughly 165 pints.
Buy on consignment
Several San Diego liquor retailers let you return unopened cases. Ask before buying — it removes the risk of over-ordering.
Don't skimp on ice and water
Plan 1.5 pounds of ice per guest and a self-serve water station. Both are constantly underestimated at outdoor events.
What separates a good bar service
A real signature cocktail menu
Two batched signature drinks keep the line short and the cost down versus a full made-to-order menu.
They bring the unglamorous stuff
Ice bins, cutting boards, jiggers, bar mats, trash cans, and towels. Confirm what's included or you'll be buying it day-of.
Glassware versus disposable
Real glassware rents for about $0.50 to $1.50 per piece and transforms the look. Budget breakage and a rinse station.
Bar placement
Put the bar away from the entrance and the food line, with room for two service points if you're over 100 guests.
A clear last-call plan
Coordinate last call 30 to 45 minutes before the venue curfew and have coffee, water, and rideshare info ready.
Before you sign an event contract
- • Get a written quote that separates rental cost, delivery, setup/strike, labor, and any overtime rate.
- • Confirm the venue's load-in window, elevator or dock access, noise curfew, and whether a permit or COI is required.
- • Ask for a certificate of insurance naming the venue as additional insured — most San Diego venues require it and it takes a few days to issue.
- • Check the weather and wind contingency in writing. Coastal afternoon wind regularly affects tents, drapery, and audio.
- • Lock your date early for May–October and December. Peak Saturdays sell out three to six months ahead.
- • This page is a local starting point, not an endorsement. Prices change; confirm directly with vendors.
