TL;DR: A 100-guest wedding in Fairfield, CA typically costs $38,000 – $62,000 all-in, with most couples landing around $48,000. Expect roughly half of that to go to venue and catering combined, driven by Solano County's ~$135–$185 per-person food-and-beverage range.
Useful summary
Fairfield sits between Napa and the Bay Area, which pulls pricing up from a pure Central Valley rate but keeps it below San Francisco or Sonoma wine-country premiums. For 100 guests, you're planning a mid-size wedding — large enough that per-person costs (catering, bar, rentals, favors, stationery) drive your total, and small enough that you can still host at boutique venues without a full buy-out fee.
Budget ranges below assume a Saturday evening wedding, full plated or buffet dinner, open bar, live band or DJ, and a local photographer. A Friday or Sunday date typically saves 10–18%, and an off-season month (January, February, late November) can save another 5–10% on venue and vendor fees.

Local context
Venue types you'll see in and around Fairfield: - Winery and vineyard venues in Suisun Valley (5–15 minutes from downtown Fairfield) — site fees $5,000 – $9,000, often with in-house catering minimums of $10,000+. - Golf club and country club venues (Rancho Solano, Paradise Valley) — typically all-inclusive packages at $120 – $165 per person. - Historic and ranch venues between Fairfield, Vacaville, and Cordelia — site fees $3,500 – $7,500, usually BYO or preferred-vendor catering. - Hotel ballrooms (Hilton Garden Inn, Courtyard) — easier logistics, per-person pricing around $110 – $150 with room-block perks.
Climate and season pricing: Summer and early fall (June–October) are peak because of mild Suisun Valley evenings, and venues charge 15–25% more on Saturdays in that window. Winter weddings are genuinely cheaper here because fog and rain risk push demand down — but indoor backup plans become non-negotiable.
Regional cost drivers: - Sales tax in Solano County is 8.375%, applied to catering, rentals, and bar. - Service charges of 20–24% are standard and often non-negotiable. - Many Bay Area photographers, florists, and bands charge a $200 – $500 travel fee to Fairfield — factor this in if you want San Francisco or Napa talent. - Napa-based vendors generally cost 20–35% more than Fairfield-local equivalents for comparable quality.

FAQ
Is $48,000 realistic for 100 guests in Fairfield?
Yes — $48,000 is the typical mid-point for a full Saturday-evening wedding with dinner, open bar, photo, DJ, and flowers. Couples who host a Friday or Sunday afternoon event, or use a restaurant or brewery venue instead of a winery, routinely come in at $32,000 – $38,000 without feeling stripped-down.
How much should I budget per guest in Fairfield?
Plan on $380 – $620 per guest all-in for a standard Fairfield wedding at 100 guests. Food and beverage alone runs $130 – $230 per person once you include the 20–24% service charge and 8.375% Solano County sales tax — don't let a per-plate quote convince you otherwise.
What's the cheapest way to cut 100-guest costs without looking cheap?
The three highest-leverage cuts are: pick a Friday or Sunday (saves 10–18%), serve beer, wine, and one signature cocktail instead of full open bar (saves $1,500 – $2,500), and choose a venue that lets you bring in outside catering (saves $15 – $40 per plate versus in-house minimums).
How does Fairfield compare to Napa or San Francisco pricing?
Fairfield runs roughly 20–35% less than Napa and 25–40% less than San Francisco for comparable weddings. The trade-off is fewer ultra-luxury venue options, but you get real savings by staying on the east side of the Carquinez Bridge while still accessing wine-country aesthetics in Suisun Valley.
Do I need a wedding planner for 100 guests?
For a 100-guest wedding at a venue without a dedicated coordinator, yes — at minimum a month-of coordinator at $1,800 – $3,200. Full-service planners run $6,000 – $12,000 in the Fairfield/Napa corridor and generally pay for themselves in vendor negotiations if your budget is above $50,000.
What's not included in the $48,000 average?
The typical total excludes the honeymoon, engagement ring, rehearsal dinner, and pre-wedding events like the bridal shower or bachelorette. Rehearsal dinners for ~20 people in Fairfield usually add $1,500 – $3,500, and honeymoons vary wildly — budget these separately from the wedding line.
How much should I hold back for unexpected costs?
Keep a 5–8% buffer — roughly $2,500 – $4,000 on a $48,000 wedding. The most common overages are final guest-count adjustments, vendor overtime, last-minute rentals (heaters, umbrellas), and gratuities you didn't pre-load into contracts.
