TL;DR: A 150-guest wedding in Simi Valley, CA typically runs $52,000 – $88,000 all-in, with most couples landing near $68,000. Catering and venue eat up about 55% of that because Ventura County per-person food and beverage minimums run $135–$210 before tax and service.
Useful summary
At 150 guests, you're in the range where fixed costs (photography, DJ, officiant, stationery) stop dominating and per-person costs take over. Every dollar you add or cut on food, drinks, rentals, and favors gets multiplied by 150.
Here's what that means in practice for Simi Valley:
- Food and beverage is your biggest lever. Moving from a buffet to a plated dinner with full bar typically adds $40–$60 per person — that's $6,000–$9,000 on a 150-person count.
- Venue choice swings your total more than any other single decision. A private estate or ranch venue in the Santa Susana foothills runs $8,000–$18,000 for site fee alone; a hotel ballroom in Simi Valley or Thousand Oaks often bundles rentals but enforces higher F&B minimums.
- Saturday evenings in May, June, September, and October are peak pricing. Moving to a Friday or Sunday can cut venue and vendor costs 15–25%.

Local context
Simi Valley sits on the eastern edge of Ventura County, so you're pulling from two distinct vendor markets: Ventura County (Simi Valley, Thousand Oaks, Camarillo) and west San Fernando Valley / greater LA. LA-based vendors will often add a $150–$400 travel fee for Simi, and some photographers cap at a 50-mile radius before charging mileage.
Venue styles that fit 150 guests locally:
- Ranch and outdoor estate venues in the Santa Susana Pass and Chatsworth hills (think Hummingbird Nest, Bella Vista Groves, Maravilla Gardens in Camarillo) — $10,000–$22,000 site fees, usually require outside catering with a preferred list.
- Wood Ranch Golf Club and Lost Canyons — country club packages, F&B minimums typically $18,000–$28,000 for 150 on a Saturday.
- Reagan Library — iconic but runs $30,000+ all-in for F&B at this guest count.
- Hotel ballrooms in Thousand Oaks and Westlake Village — predictable pricing, fewer rental surprises.
Climate and timing: Summer ceremonies in Simi Valley regularly hit 95–105°F — outdoor ceremonies before 5pm in July and August need shade structures or fans, which adds $400–$1,500. The sweet spot is late September through early November and March through May, when daytime highs sit in the 70s and vendor availability is still solid if you book 9–12 months out.
Santa Ana winds (October–December) can affect outdoor florals, tent setups, and hair — build a Plan B into your contract.

FAQ
Is $50,000 enough for a 150-guest wedding in Simi Valley?
It's doable but tight. You'll likely need a Friday or Sunday date, a venue with inclusive rentals, a buffet or station-style meal, beer-and-wine bar, and a DJ rather than a band. Expect to skip videography or trim florals to stay under $50K.
What's the single biggest cost driver at 150 guests?
Bar service. A full open bar at a Simi Valley venue runs $45–$75 per guest for 4–5 hours — that's $6,750–$11,250 for 150 people. Switching to beer, wine, and two signature cocktails typically saves $2,500–$4,000 with minimal guest impact.
How much should I budget per guest in Simi Valley?
Plan on $350–$500 per guest all-in for a typical Simi Valley wedding, or $450–$600 per guest for an elevated experience. Lean weddings can hit $320 per guest, but usually only with a non-Saturday date and a DIY-heavy approach.
Do I need a day-of coordinator at this guest count?
Yes. At 150 guests with Ventura County's mix of outdoor venues, weather variables, and multiple vendor teams, a day-of coordinator is the highest-ROI line item in your budget. Expect $1,800–$3,500 for month-of service; full planning runs $6,000–$12,000.
How far in advance should I book vendors for a 150-guest Simi Valley wedding?
Book your venue 12–14 months out, photographer and caterer 10–12 months, and florist, DJ, and coordinator 8–10 months. Peak-season Saturdays (May, June, September, October) book first — top venues are often gone 14–18 months ahead.
What hidden costs catch Simi Valley couples off guard?
The big three: 22–24% service charges on catering (often confused with tip), Ventura County sales tax on rentals and food, and vendor travel fees for LA-based photographers and florists. Together these can add $9,000–$14,000 to a $60,000 vendor subtotal.
Can I save money by hosting in a backyard or private property?
Sometimes, but not as much as you'd think. By the time you rent tents, tables, chairs, linens, dance floor, lighting, generators, portable restrooms, and a catering prep kitchen for 150 guests, you're usually at $18,000–$28,000 in rentals alone — often within $3,000 of a turnkey venue.
