San Mateo County California Fairgrounds Events
San Mateo County Fairgrounds, officially known as the San Mateo County Event Center, is a major gathering place for residents of the San Francisco Peninsula. Located in San Mateo, California, the venue hosts the annual San Mateo County Fair alongside trade shows, consumer exhibitions, concerts, cultural celebrations, business events, and community programs.
Unlike smaller rural fairgrounds that operate mainly during a short summer fair, the San Mateo County Event Center remains active throughout the year. Its combination of indoor exhibition halls, outdoor event space, parking areas, and livestock exhibits makes it useful for both large public gatherings and private events.
The annual fair remains the main attraction for families looking for carnival rides, fair food, live entertainment, arts and crafts, agricultural education, and youth competitions. For vendors, exhibitors, and event organizers, the grounds also offer opportunities to reach audiences from San Mateo, Burlingame, Redwood City, South San Francisco, and the wider Bay Area.
The most important planning detail for visitors is that the 2027 San Mateo County Fair is scheduled for June 4–13, 2027, according to the fair’s published announcement. Individual event dates, admission arrangements, and operating hours should be checked again as the fair approaches.
Overview of San Mateo County Fairgrounds
Location and address
The San Mateo County Event Center is located in San Mateo, within the urban Peninsula corridor between San Francisco and San Jose.
- Main event parking entrance: 1346 Saratoga Drive, San Mateo, CA 94403.
- Administrative office: 2495 South Delaware Street, San Mateo, CA 94403.
- Telephone: (650) 574-3247.
Visitors should distinguish the event parking entrance from the administrative mailing address when entering a navigation app. Some events may direct attendees to a different gate or parking area.
The grounds cover approximately 48 acres and contain seven principal buildings, with more than 195,000 square feet of indoor exhibition space. The combination of indoor halls and outdoor areas allows organizers to accommodate trade exhibitions, festivals, concerts, public gatherings, and the county fair.
Who operates the fairgrounds?
San Mateo County owns the property, while the nonprofit San Mateo County Exposition and Fair Association manages and operates the venue under an agreement with the county. Its responsibilities include maintaining the grounds, administering events, arranging facility rentals, and overseeing the annual fair.
This arrangement makes the Event Center both a public gathering place and a year-round event business. Its schedule extends well beyond agricultural exhibitions, although the fair’s horticultural and educational roots remain central to its identity.
Why the grounds matter locally
San Mateo County is widely associated with technology, business, coastal communities, and suburban development. The county fair provides a different kind of local experience, bringing agricultural education, creative exhibits, family entertainment, and community organizations together in one place.
For young exhibitors, it offers a setting to present projects and learn about animal care, horticulture, and practical skills. For local businesses and nonprofit groups, it creates opportunities to meet residents directly. For longtime fairgoers, it remains an established summer tradition.
Upcoming Events at San Mateo County Fairgrounds
The Event Center hosts public events throughout the year, so visitors should not assume that every activity follows the summer fair calendar.
Seasonal events and year-round activities
The venue’s event mix includes:
- Consumer expos, home and garden exhibitions, and specialty trade shows.
- Cultural festivals, community celebrations, and family entertainment.
- Concerts, public performances, and music festivals.
- Craft, hobby, collectible, and other ticketed exhibitions organized by outside promoters.
- Business conferences, corporate gatherings, fundraisers, and private functions.
- The annual county fair, featuring carnival attractions, food vendors, exhibits, and agricultural programming.
Spring and autumn can bring indoor exhibitions and consumer events, while summer is especially associated with the county fair and its outdoor entertainment. Winter dates depend on the bookings made by individual organizers.
These are general seasonal patterns, not a guarantee that a particular event will return each year. The venue’s current event calendar is the best source for confirmed dates, ticket availability, and admission requirements.
How to check upcoming events
Search for the San Mateo County Event Center event calendar or the San Mateo County Fair schedule, depending on the event you want to attend. The fair also maintains its own social media presence for announcements and changes.
Outside promoters may sell tickets separately and establish their own rules. Check the specific event listing before traveling, particularly if you need accessible seating, want to bring children, or plan to arrive in a large vehicle.
Facility rentals and private events
The Event Center rents facilities to outside organizations. Its halls and outdoor spaces can accommodate conferences, public exhibitions, corporate events, celebrations, and other gatherings.
Rental suitability depends on the building, event size, layout, equipment, and date. Organizers should contact the venue’s sales or event management staff for current availability, rental rates, insurance requirements, and setup arrangements.
The San Mateo County Fair: Dates, Attractions, and Admission
When is the county fair?
The San Mateo County Fair is the venue’s signature annual event. Its 2026 edition ran from June 5 through June 14, with the grounds closed to the public on June 8 and 9. The next announced fair is scheduled for June 4–13, 2027.
The dates provide a useful starting point for planning a family outing, entering an exhibit, or applying for a vendor space. However, the 2027 daily schedule, ticket prices, and entertainment lineup should be confirmed through official announcements rather than inferred from the previous year’s program.
Livestock, agriculture, and competitive exhibits
Although San Mateo County is more urbanized than many California agricultural counties, the fair continues to make room for agriculture and hands-on education. Its program includes livestock-related activities, a fair farm, and competitive exhibits that connect visitors with animal care, gardening, and traditional fair skills.
Competitive exhibits can include creative and educational categories such as:
- Horticulture, flowers, and garden-related projects.
- Photography, fine art, crafts, and other handmade work.
- Baking, preserving, and home arts where included in the current competition schedule.
- Youth projects and educational displays.
- Livestock and animal-related competitions listed in the year’s premium book.
The exact species, classes, entry limits, and judging times vary by year. Do not assume that every traditional agricultural category offered at a rural county fair is available at San Mateo’s event. Exhibitors should review the current rules before preparing an entry.
Carnival rides, food, and entertainment
The fair features a midway with carnival rides and games, along with fair food, shopping, exhibits, and live performances. Depending on the year’s program, visitors can plan for an afternoon of family activities or an evening built around concerts and carnival attractions.
Typical American fair favorites may include corn dogs, funnel cakes, fried treats, burgers, barbecue, and sweet snacks, but individual vendors and menus change from year to year. Visitors with dietary restrictions should check current vendor information rather than rely on past offerings.
Carnival wristbands or other ride packages may be offered, but prices, eligible rides, and promotional days must be confirmed for the specific fair. Admission to the fair should not automatically be assumed to cover every separately priced attraction.
The entertainment program can include live music, cultural performances, themed celebrations, and special events. In 2026, the fair featured the Bayside 101 Music Festival during opening weekend. That is a past example, not confirmation of the 2027 lineup.
Admission, parking, and operating hours
The 2026 fair operated from 4 p.m. to 10 p.m. on opening Friday, June 5, and from 11 a.m. to 10 p.m. on operating days from June 6 through June 14, excluding June 8 and 9.
Those hours should not be treated as the 2027 schedule. Admission prices, children’s tickets, senior discounts, parking fees, and any free-admission promotions also require confirmation for the next fair. Event Center parking arrangements can differ from ordinary year-round event parking.
Visitors exploring San Mateo County California Fairgrounds Events can also discover regional celebrations through San Luis Obispo County California Fairgrounds Events. Exploring both locations helps visitors discover local heritage, enjoy community gatherings, and find seasonal activities throughout California.
Facilities and Grounds
Exhibition buildings and outdoor spaces
The 48-acre property has seven principal buildings and more than 195,000 square feet of indoor exhibit space. Its layout supports large trade shows, consumer events, conferences, community gatherings, and the county fair.
Fiesta Hall is one of the venue’s established exhibition spaces, associated with events ranging from trade shows and concerts to community fundraisers. Other facilities support different event sizes and layouts. The specific building assigned to an event depends on the organizer’s contract.
Livestock and arena facilities
Agricultural exhibits and animal-related programming form part of the county fair, but barn access, animal housing, stall assignments, and unloading arrangements depend on the competition rules. Exhibitors should not assume that livestock facilities can be rented independently or that all species have dedicated permanent barns.
The current fair office can clarify check-in times, animal health documentation, bedding, feed, exhibitor parking, and any restrictions on vehicles or trailers.
Parking, accessibility, and amenities
The venue has multiple large parking areas, with entry locations determined by the event. For the annual fair, follow the published parking instructions and any temporary traffic controls around Saratoga Drive and South Delaware Street.
Visitors who need accessible parking, wheelchair access, or an accommodation should contact the venue before arrival to confirm the arrangements for their particular event. Accessible facilities and services may vary by building and temporary event setup.
Food concessions, restrooms, and other amenities depend on the event. Do not assume that ATMs, first-aid stations, water refill points, or every concession stand will be available at every exhibition.
Camping and RV facilities
The Event Center’s wider property includes a separately identified RV facility, Bay Stay RV. However, that does not establish that fair visitors can camp on the grounds during fair week or that RV spaces are included with event parking.
Anyone planning an RV stay should verify operating dates, reservation rules, hookups, fees, and whether overnight stays are permitted for the event in question.
Vendor and Exhibitor Information
Applying for a commercial booth
The fair offers opportunities for commercial vendors, exhibitors, and food concessionaires. Applications are handled through the fair’s vendor program, with different processes for selling merchandise, serving food, and pursuing sponsorships.
Before applying, prepare a clear description of your products, business details, booth requirements, and any applicable permits. Food businesses should ask about health requirements, menus, equipment, and service arrangements. Commercial merchandise vendors should confirm which categories are accepted and whether their products qualify.
Application windows can close well before fair week. A previous year’s application form should not be assumed valid for the next fair.
Entering competitive exhibits
People interested in displaying artwork, photographs, crafts, horticultural projects, baked goods, or other eligible entries should look for the current competitive exhibits guide or premium book.
That document establishes class descriptions, eligibility, entry deadlines, drop-off arrangements, judging procedures, and pickup requirements. Livestock exhibitors should also review animal-specific rules and health documentation.
For vendor, exhibitor, and general fair inquiries, contact the fair office at (650) 574-3247. The venue’s administration office is generally open Monday through Friday, 8:30 a.m. to 5 p.m.; public event hours are different.
Getting to San Mateo County Fairgrounds
Driving directions
The grounds are in San Mateo, between San Francisco and San Jose, making them accessible to visitors from across the Peninsula and the wider Bay Area.
- From downtown San Mateo: Follow local roads toward Saratoga Drive and the South Delaware Street area, checking the event’s designated entrance.
- From San Francisco: Take US-101 south toward San Mateo and follow the current event-specific directions.
- From San Jose: Take US-101 north toward San Mateo, then follow the posted approach to the Event Center.
- From the surrounding Peninsula: Allow additional time for local traffic near the venue, especially during major exhibitions and fair week.
Traffic patterns and temporary road controls can change. Use the entrance named in your event ticket or visitor instructions rather than relying solely on a general map destination.
Public transportation and rideshare
The Event Center provides visitor information for Caltrain, BART connections, and SamTrans services. The best route depends on the origin station, bus schedule, and event hours, so confirm connections before leaving.
The venue identifies 2544 South Delaware Street as a rideshare drop-off address. Check event-day instructions in case the designated pickup or drop-off arrangement changes. During major events, allow extra time for congestion and for walking from the drop-off area to the entrance.
4-H and FFA at San Mateo County Fairgrounds
Youth agriculture and educational programs
The fair’s educational mission includes youth development, agricultural science, horticulture, arts, and sustainability. Its livestock and project exhibits can give young people an opportunity to demonstrate skills, learn from judges, and share their work with the public.
San Mateo County’s 4-H and local FFA programs are relevant starting points for young people interested in animal science, agricultural education, and project-based learning. However, the number of active clubs, participating FFA chapters, and eligible livestock classes should be confirmed with the relevant organizations for the current season.
Junior livestock auction
A junior livestock auction, when included in the fair’s annual program, gives eligible youth exhibitors an opportunity to present animals they have raised and sell them to participating buyers. Depending on the auction’s rules, buyers may include local businesses, community members, and supporters of youth agricultural education.
The fair’s 2026 program listed a livestock auction for Saturday, June 13. That confirms a recent example, not the date or precise format of the 2027 auction.
Before participating, exhibitors should review eligibility, weigh-in requirements, animal care rules, buyer registration, sale procedures, and how proceeds are distributed. Families should also verify whether any sale proceeds are subject to fees or deductions.
Special Events Beyond the Annual Fair
The fairgrounds’ year-round schedule is one of their defining features. Visitors who miss the summer fair can still find other events at the venue, although the offerings depend on outside bookings.
Trade shows, consumer exhibitions, and community gatherings
Indoor halls make the property suitable for product showcases, specialty expos, hobby events, public exhibitions, and professional gatherings. These events often have their own organizers, ticketing systems, and entry policies.
Community organizations can also use the grounds for fundraisers, cultural events, and educational programs. Private event rentals are available, subject to the venue’s schedule and rental conditions.
Concerts, festivals, and family entertainment
The county fair is the most recognizable recurring festival, but the wider Event Center calendar can include music performances, celebrations, and other entertainment. Concert access, age restrictions, parking, and ticket packages depend on the individual event.
Gun shows, flea markets, rodeos, and motorsports
These are common searches for fairgrounds in general, but they should not be mistaken for confirmed recurring San Mateo County Event Center offerings. A particular gun show, flea market, rodeo, demolition derby, tractor pull, or motorsports event should only be included in a visitor’s plans when it appears on the current calendar or is confirmed by its organizer.
The same applies to seasonal harvest festivals and holiday events. Check the actual listing before assuming that an activity takes place at this venue.
History of San Mateo County Fairgrounds
From the Little Flower Show to a regional event center
The fair’s history dates to 1926, when the Burlingame Garden and Flower Club organized an event called the Little Flower Show. Early exhibitions took place at different schools around San Mateo County, reflecting the area’s interest in gardening, flowers, and community participation.
The event developed over time, taking names including San Mateo County Products and Floral Fiesta before becoming the San Mateo County Fair. In 1935, during a period of fair revitalization, it moved to its home near the former Bay Meadows Racetrack area.
The property subsequently expanded and evolved into the modern San Mateo County Event Center. What began as a small floral exhibition is now a multipurpose venue that hosts public exhibitions, trade events, concerts, community programs, and the annual fair.
How the grounds have changed
The Event Center’s indoor exhibition buildings and outdoor spaces allow it to serve a much wider audience than the original flower show. Its role also extends to community resilience and emergency-response support, in addition to entertainment and commercial events.
The fair’s continued emphasis on horticulture, youth participation, creative exhibits, and educational programming provides a connection to its early roots.
For visitors, that history explains why the event is not simply a carnival. It combines agricultural and community traditions with the needs of a densely populated, economically diverse region.
