TL;DR: A 150-guest wedding in Antioch, CA typically costs $42,000 – $68,000 all-in, with most couples landing near $52,000 (about $347 per guest). Catering and venue together consume roughly 55% of that, and East Contra Costa pricing runs 15–20% below San Francisco and Napa but above Central Valley rates.
Useful summary
At 150 guests, you're firmly in "full wedding" territory — this is the guest count where per-person costs drop slightly (volume discounts on catering, flat venue fees spread wider) but absolute dollars climb fast. Here's what matters for your budget:
- Plan on $280–$450 per guest depending on whether you're doing buffet or plated, beer-and-wine or full bar, DJ or live band.
- Venue + catering is the lever. A $45,000 budget and a $28,000 venue rental are incompatible. Pick the venue last, after you know your number.
- Build in a 10% contingency. Overages on flowers, upgrades, and last-minute guest additions are the rule, not the exception.
- Tax and service charges are not optional. Contra Costa sales tax is 9.75%, and most full-service caterers add a 20–22% service fee on top.

Local context
Antioch sits in eastern Contra Costa County, which gives you real budget advantages over the Bay Area core. Venues here price closer to Sacramento than San Francisco.
Where people get married locally: - Lone Tree Golf & Event Center and local country clubs — all-inclusive packages in the $18K–$28K range for 150 guests (food + venue combined). - Brentwood and Byron wineries (just east) — rustic aesthetic, $6K–$12K site fees, bring-your-own caterer. - Private estates and backyard weddings — popular on the Antioch/Oakley border, but budget $10K+ for rentals (tent, tables, chairs, restrooms, generators) if the site is raw. - Downtown Walnut Creek and Danville venues — 30 minutes west, add ~20% to pricing.
Climate and season pricing: May through October is peak, with September and October commanding the highest rates. Antioch summers regularly hit 95–105°F in July and August — if you're doing outdoor, budget for shade structures, fans, or a tent with sides (~$1,500–$3,000 extra). Delta breeze helps after 5 p.m.
Cost drivers specific to this area: - Most full-service caterers come from Concord, Walnut Creek, or Stockton — expect travel/delivery fees of $200–$500. - Floral vendors often source from the SF Flower Mart; local Antioch florists run 10–15% cheaper than Lafayette or Danville. - Guest lodging is limited in Antioch proper — reserve hotel blocks in Brentwood or Concord early.

FAQ
What's the minimum realistic budget for 150 guests in Antioch?
Around $38,000–$42,000 if you use an all-inclusive venue (golf club or banquet hall), choose a buffet, limit to beer and wine, and book a DJ instead of a band. Going below $35K at 150 guests almost always means cutting essentials like photography hours or moving to a Friday/Sunday date.
How much should I budget just for food and drink?
Plan on $120–$180 per guest total for catering plus bar, so $18,000–$27,000 for 150 guests. That assumes a seated dinner with beer/wine service and includes the 20–22% service charge most caterers add. Full open bar pushes the top end another $2,000–$4,000.
Is Antioch cheaper than Napa or San Francisco for weddings?
Yes — expect to pay 15–25% less than comparable Napa wineries and 20–30% less than San Francisco venues for the same guest count. The savings are biggest on venue rental and floral; photography and DJ rates are similar across the Bay Area.
How much does an off-season or weekday wedding save?
A Friday or Sunday date in Antioch typically saves 10–15% on venue and often on photography. November through March (excluding holidays) can save another 10–20% on venue fees. Combined, an off-peak weekday can cut $5,000–$8,000 off a $55K budget.
What's the single most common budget mistake at 150 guests?
Underestimating the bar. Couples budget $20–$30 per guest for beer and wine and end up at $45–$55 per guest once you factor in signature cocktails, ice, glassware rental, bartender fees, and corkage if the venue requires it. Get line-item quotes before committing.
Should I hire a wedding planner at this budget?
At $50K+ with 150 guests, a full-service planner ($6,000–$10,000) or at minimum a month-of coordinator ($1,500–$2,500) typically pays for itself in vendor negotiations and day-of problem-solving. Most Antioch venues require a coordinator regardless.
How far in advance should I book venues in Antioch?
9–14 months out for peak-season Saturdays (May–October). Popular local venues like Lone Tree and the Brentwood wineries often book 12+ months ahead for September and October dates. Off-season dates can often be secured 4–6 months out.
