A 100-guest wedding in Thousand Oaks, CA typically runs $52,000 – $88,000 all-in, with most couples landing near $68,000. Venue and catering alone usually consume 50–55% of that total, driven by Conejo Valley vineyard and ranch pricing that tracks closer to greater Los Angeles than to Ventura County's coastal averages.
Useful summary
For a 100-guest wedding in Thousand Oaks, plan on a per-guest cost of roughly $520 – $880, with the spread driven mostly by venue choice (private estate vs. country club vs. winery), Saturday-vs.-Friday pricing, and whether you bring in outside catering or use an in-house team.
A few realities to anchor your budget:
- Catering minimums at popular Hidden Valley and Westlake venues frequently sit at $185 – $275 per person before tax and 22–24% service.
- Saturday peak season (May, June, September, October) adds 15–25% to venue site fees vs. a Friday or Sunday in the same month.
- Vendor travel fees are common — many top photographers and florists are based in LA or Santa Barbara and charge $250 – $750 to cover the drive.
- Bar service for 100 guests runs $4,500 – $9,000 depending on whether you do beer/wine only or full bar with signature cocktails.

Local context
Thousand Oaks sits in the Conejo Valley, and your venue options usually fall into four buckets:
- Wineries and ranches in Hidden Valley, Lake Sherwood, and Westlake Village — think Maravilla Gardens, Hummingbird Nest Ranch (nearby Santa Susana), and similar estates. Site fees $9,000 – $20,000, often with required catering partners.
- Country clubs like Sherwood Country Club, Los Robles Greens, and North Ranch — in-house catering, all-in pricing, generally cleaner logistics.
- Hotels and resorts including the Four Seasons Westlake Village — full-service, predictable, on the higher end.
- Backyard / private estate weddings in the hills above Thousand Oaks — lower venue cost, but you pay it back in rentals (tents, generators, restrooms, dance floor, lighting) that typically add $12,000 – $25,000.
Climate is friendly almost year-round. Outdoor ceremonies work April through November, but August/September afternoons regularly hit 90–98°F, so plan ceremony timing for late afternoon and budget for shade structures or fans (~$400 – $1,200). October Santa Ana winds are real — secure your florals and signage.
Sales tax and service charges in Ventura County add up fast. Catering invoices typically include 22–24% service plus 7.25% sales tax on food and rentals. Build that into your per-person math from day one, not at the end.

FAQ
Is $50,000 enough for a 100-guest wedding in Thousand Oaks?
It's tight but doable. You'd likely need a Friday or Sunday date, a venue under $9,000 in site fees, beer-and-wine-only bar, and a willingness to skip videography or use a less in-demand photographer. Plan on $500/guest as your working ceiling.
What's the single biggest cost driver locally?
Catering. Conejo Valley venue caterers commonly require $185 – $275 per person plus 22–24% service plus tax, which puts food and beverage alone at $25,000 – $40,000 for 100 guests. Choosing a venue that allows outside catering can save $8,000 – $15,000.
How much should I budget for a planner?
A full-service planner in the Thousand Oaks / Westlake market runs $7,500 – $15,000, while month-of coordination is typically $2,500 – $4,500. For a 100-guest wedding at a venue that doesn't include a coordinator, month-of is the minimum we'd recommend.
When should I book to lock in current pricing?
Most in-demand Conejo Valley venues book 12–18 months ahead for Saturday peak-season dates, and many vendors raise rates each January. Booking 14+ months out typically locks pricing and gives you the widest vendor pool.
Do I need to budget for guest transportation?
If your venue is in Hidden Valley or up Potrero Road, yes. Cell service is spotty and rideshares are unreliable, so most couples spend $1,500 – $3,500 on shuttles from a Westlake or Thousand Oaks hotel block. Build it into the budget upfront, not as a surprise add-on.
How much buffer should I leave?
Add a 10% contingency line — roughly $5,000 – $8,000 on a $50K – $80K budget. It almost always gets used on overtime, last-minute rentals, gratuities, or guest count creep in the final 60 days.
Are tax and service charges already in vendor quotes?
Usually not. Most catering and rental quotes show subtotals; the 22–24% service charge and 7.25% Ventura County sales tax are added later and can shift a $25,000 catering quote to over $33,000. Always ask for an "all-in" estimate before signing.
