Tucked along Gravenstein Highway South in Sebastopol, The Antique Society fills a 1930s commercial building that once housed the Henderson Furnace Company. The Art Deco structure — broad, geometric and built to last — earned a Historic Preservation Award in 1999. It now holds one of Sonoma County's most serious antique collectives, with over 100 dealers spread across roughly 20,000 square feet of floor space.
The scale shapes the whole experience. Furniture and architectural salvage anchor one end of the spectrum: mid-century modern pieces, reclaimed fixtures and the kind of structural objects that interior designers drive out from the Bay Area to find. Elsewhere, dealers carry vintage clothing, glassware, decorative signs and rugs. A quieter strand of the floor pulls toward art, stone carvings and objects that feel less like flea market finds and more like considered acquisitions.
What separates the Antique Society from a standard antique mall is the dealer mix. Pickers, working artists, seasoned collectors and interior designers share the floor with people who have held their stalls for decades. Long-tenured sellers know their stock in genuine depth. Conversations tend to go somewhere useful — not just polite small talk, but the kind of exchange that points you toward the right piece or explains why something is priced the way it is.
The collective opened in 1989 and has grown steadily since. Its reputation in Sonoma County rests on two things: consistent quality across the floor and pricing that brings shoppers back rather than pushing them away. Most visitors arrive looking for something specific and leave carrying things they hadn't planned on. That productive unpredictability is part of the appeal, and it keeps the place from feeling like a browsed-out destination.
The market opens every day from 10:00 to 17:00, which makes it easy to work into a wider day in wine country. A bakery and café operates on site — a natural pause point in a space this large. Coming up for coffee mid-browse tends to reset the eye and send people back for a second pass through sections they moved through too quickly the first time.
Twice a year, the Antique Society expands into the surrounding parking lot for an outdoor sale. The main floor stays open on those days. The combination of covered stalls and open-air dealers creates a density worth timing a trip around, especially for collectors who want maximum range in a single visit.
Bus stops on Highway 116 serve the area near the market. The closest stop sits at Hwy 116 and Fredricks Road, approximately 200 metres away. Additional stops along the same corridor bring other parts of Sebastopol and the surrounding Sonoma County towns within reasonable reach. Most visitors arriving from the Bay Area or the wider wine country corridor arrive by car, and the site has parking on site for the purpose.
Frequently Asked Questions
Q: How large is The Antique Society, and how long should I plan to spend there?
A: The floor runs to around 20,000 square feet with more than 100 dealers, so a thorough visit easily fills two to three hours. An on-site bakery and café gives you a natural break point mid-browse — most visitors find a coffee stop sends them back for a second pass through sections they moved through too quickly the first time.
Q: What kinds of pieces are the dealers known for?
A: Mid-century modern furniture and architectural salvage are among the stronger draws, particularly for interior designers and collectors making the drive from the Bay Area. Beyond furniture, dealers carry vintage clothing, glassware, decorative signs, rugs, stone carvings and artwork — the floor has enough range that different kinds of collectors tend to find their own corner of it.
Q: Does The Antique Society ever expand beyond its main building?
A: Twice a year the market spills into the surrounding parking lot for an outdoor sale, with the main 1930s building staying open at the same time. The combined density of covered floor and open-air stalls makes those dates worth timing a trip around, especially if you want maximum range in a single visit. Check the organizer's official channels for current sale dates before you go.
Q: Is it worth talking to the dealers, or is this more of a browse-and-move-on kind of market?
A: Conversation is genuinely useful here. Many dealers have held the same stall for years and know their stock in real depth — the kind of exchange that explains why something is priced the way it is, or points you toward a piece you hadn't noticed. The mix of pickers, working artists and seasoned collectors means the floor has a different character from a more uniform antique mall.
Q: How do I get there, and is public transit an option?
A: The Antique Society sits on Gravenstein Highway South in Sebastopol. Most visitors from the Bay Area arrive by car, and the surrounding Sonoma County wine country towns make it easy to build into a wider day. Bus stops on Highway 116 serve the area, with the closest stop at Hwy 116 and Fredricks Road approximately 200 metres from the market — confirm current routes and schedules with Sonoma County Transit before your visit.
