Quick Answer: San Anselmo is a town of roughly 12,800 residents in Marin County's Ross Valley (ZIP 94960), incorporated in 1907 around "the Hub" — the old rail junction where Sir Francis Drake Boulevard, Red Hill Avenue, and Center Boulevard still meet. It pairs one of Marin's best independent downtowns with its most historically rich housing stock: the majority of homes predate 1940. The 94960 ZIP also includes Sleepy Hollow, an unincorporated county community along Butterfield Road. There are no Mello-Roos taxes; the diligence items that actually move deals here are San Anselmo Creek's flood map downtown and the Drake-corridor commute, since no freeway or rail line touches the town.
Key Takeaways
San Anselmo's geography is a rail map with the rails removed. The town incorporated in 1907 around the Hub, the junction where the Ross Valley's interurban lines split toward San Rafael and toward West Marin — and where Sir Francis Drake Boulevard, Red Hill Avenue, and Center Boulevard still converge today. Every San Anselmo commute funnels through that junction, which makes it both the town's historical identity and its most practical due-diligence stop. The name is older still, tracing to the Mexican land-grant era's Cañada de Anselmo — Anselm's Valley.
The 94960 ZIP is bigger than the town. Sleepy Hollow, the valley running north along Butterfield Road, carries San Anselmo addresses but sits in unincorporated Marin County: county planning governs it, the community association and its clubhouse-and-pool life organize it, and San Domenico School occupies the valley's end. City-versus-county jurisdiction changes the rulebook for permits and planning, so I confirm it on day one for any 94960 property.
San Anselmo is the Ross Valley's depth market — more homes, more price points, and more period housing stock than Ross or Fairfax on either side of it. In my quarter-by-quarter BAREIS MLS analysis, the town trades on two durable premiums. The first is period integrity: with most of the stock predating 1940, well-preserved Craftsman and Tudor-era homes draw a dedicated buyer pool, and thoughtful updates that keep original detail routinely outperform character-stripped remodels. The second is the walk-to-downtown radius, where the cottage stock closest to San Anselmo Avenue clears fastest of anything in town.
The bifurcation that runs through all of Marin applies here with a local twist: flood-zone clarity. Homes with clean FEMA status and documented drainage history compete immediately; creek-adjacent listings that arrive without the flood story already answered give buyers pause and leverage. Sellers here win by doing the water homework before listing, not during escrow.
This guide is deliberately evergreen, so the perishable numbers live where I update them constantly: my Marin Market Intelligence briefings and video library carry the current quarter's BAREIS MLS data for San Anselmo, and you can browse current listings at any time.
The town sorts by distance from the Avenue and elevation off the valley floor:
San Anselmo explains itself in a loop from the Hub to the end of Sleepy Hollow — about 15 minutes of driving without stops. Do it twice: once at 8:00 AM on a weekday, because the Hub at commute hour is a data point no listing discloses, and once on a Saturday when the Avenue is doing what it does best.
Stop 1 — The Hub. Start at the junction of Sir Francis Drake, Red Hill Avenue, and Center Boulevard. A century ago the interurban lines split here toward San Rafael and West Marin; today every commute in town negotiates this intersection. If you're serious about a specific home, time your pass through the Hub at your actual departure hour — it is the single most honest commute test in the Ross Valley.
Stop 2 — San Anselmo Avenue on foot. Park and walk the downtown blocks: the antiques storefronts the town has been known for, Comforts and M.H. Bread & Butter, Imagination Park's Yoda and Indiana Jones bronzes on the land George Lucas gave the town, and Creek Park behind the Avenue. Then look at the creek itself — note how close the channel runs to the buildings, and where structures once spanned it. That observation is the town's flood story in physical form.
Stop 3 — Seminary Hill. Climb the loop around the seminary's stone halls, the town's most distinctive landmark since the 1890s. Watch how quickly the streets gain elevation, canopy, and Tam views — and note which candidate homes sit above the valley floor's flood conversation entirely. Orientation matters up here: south-facing slopes bank the sun this valley is known for.
Stop 4 — Yolanda and Winship Park. Descend and roll the bungalow blocks of the Yolanda District and Winship Park slowly. This is the pre-1940 depth that makes San Anselmo's housing stock unusual in Marin — look for the original-detail homes versus the stripped remodels, because that difference is where this market's value judgments actually happen.
Stop 5 — Butterfield Road into Sleepy Hollow. Drive Butterfield Road the full length of the valley. Feel the shift as you cross into unincorporated county territory: lots widen, mid-century ranches replace bungalows, and the community association's clubhouse-and-pool life organizes the neighborhood. Note that Butterfield is effectively the one road in and out — a practical evacuation-planning observation — and San Domenico School marks the valley's end.
Stop 6 — Memorial Park and Robson-Harrington. Loop back via Memorial Park's fields and the gardens at Robson-Harrington House — the everyday-life layer that doesn't photograph in listings but decides how a town actually feels on a Tuesday afternoon.
Optional extensions. Walk into the Sleepy Hollow Preserve's 1,100 acres of ridge trails for the Tam-to-Big-Rock panorama, take Bolinas Avenue toward Ross and Phoenix Lake for the watershed's flagship walk, or climb White's Hill toward Fairfax to preview the West Marin doorstep.

San Anselmo holds one of Marin's deepest period-home markets: the majority of the housing stock predates 1940. Craftsman bungalows, Tudor cottages, Spanish revival, and early Victorians line the flats and lower slopes — Downtown, Yolanda, Winship Park, Brookside — many thoughtfully updated behind intact original detail: built-ins, millwork, true divided-light windows. Mid-century ranches dominate Sleepy Hollow and the upper hillsides, and the Bald Hill slopes add view remodels and custom builds. The market pays for period integrity here: a well-preserved 1920s home with sympathetic systems updates is its own product category, distinct from — and often outperforming — the gut-remodel next door.
The pre-war stock carries pre-war diligence: foundations, knob-and-tube-era electrical histories, sewer laterals in the Ross Valley Sanitary District's aging network, and drainage on the creekside flats. None of it is exotic; all of it belongs in the inspection scope before contingencies come off.
San Anselmo Creek is the town's founding geography and its signature diligence item. The creek runs directly through downtown — buildings were historically built out over the channel, and several have since been removed to improve flood capacity — and the Ross Valley's benchmark event remains the New Year's Eve 2005 storm, which flooded downtown and much of the valley. Creek-adjacent and low-lying parcels can sit in mapped FEMA zones where financed purchases typically require flood insurance, and many Ross Valley tax bills carry a storm-drainage fee funding the watershed's ongoing flood-risk-reduction work.
The buyer protocol is straightforward: check the FEMA map for the specific parcel, read the flood and drainage disclosures closely, ask about sump systems and floodproofing on the flats, and price insurance early. Sellers on the flats should assemble that water story before listing — a clean, documented answer converts the town's best-known question into a non-issue.
Daily life orbits San Anselmo Avenue — one of Marin's genuinely used downtowns, long known as an antiques destination and anchored by institutions like Comforts and M.H. Bread & Butter, with Creek Park's summer music series and the long-running Art & Wine Festival carrying the calendar. Imagination Park gives the town its most photographed corner: bronze Yoda and Indiana Jones on land donated by George Lucas, who wrote much of the original Star Wars while living here in the 1970s. Everyday errands run through the Red Hill Shopping Center, and the Ross Valley's shared institutions — one school district, one fire department — stitch the town to its neighbors.
The outdoor ledger is the Ross Valley's: the Sleepy Hollow Preserve's 1,100 acres of ridge trails, Bald Hill looming over town with its summit panorama, Memorial Park's fields, the Robson-Harrington gardens, and the Mount Tamalpais watershed's trail network minutes away via Ross and Fairfax. West Marin — Samuel P. Taylor's redwoods, the coast beyond — starts one hill west.
The Ross Valley School District serves grades K-8, including Brookside and Wade Thomas elementary schools in San Anselmo and Hidden Valley Elementary in Sleepy Hollow, feeding White Hill Middle School in Fairfax. For grades 9-12, the town belongs to the Tamalpais Union High School District at Archie Williams High School — located in San Anselmo itself and renamed from Drake High in 2021. Private options include St. Anselm School downtown and San Domenico School in Sleepy Hollow. For performance data, consult GreatSchools and the California School Dashboard directly, and verify current assignments for any specific address.
San Anselmo is a corridor town, not a freeway town — and honest math matters here. By car, plan on roughly 35 to 50 minutes to downtown San Francisco at peak: Sir Francis Drake Boulevard to US-101 at Greenbrae, then the bridge, with the Hub and the Drake corridor as the variables. The strong alternative is the Larkspur ferry terminal about ten minutes away — with the SMART station beside it — which converts the worst stretch of the drive into a half-hour on the water. Golden Gate Transit buses run the Drake corridor, and e-bike-to-ferry is genuinely viable from the flats. Test your actual route through the Hub at your actual hour before you commit.
The structural stack is clean: no Mello-Roos Community Facilities Districts anywhere in town, and HOAs essentially absent from the single-family stock outside small condo pockets — Sleepy Hollow's community association is a neighborhood institution rather than a mandatory master HOA, with specifics worth confirming in title. Beyond the roughly one percent base property tax, expect school parcel taxes, the Marin Wildfire Prevention Authority (Measure C) tax, and the Ross Valley flood-control fee on many parcels. I pull the actual tax bill for any property a client is serious about.
Creek-adjacent and low-lying parcels add the water stack: FEMA zone verification, flood insurance where mapped, drainage and sump history, and the pre-war foundation questions that come with the housing stock's age. Ask early whether sewer-lateral requirements apply at transfer in the Ross Valley Sanitary District's network.
The Bald Hill slopes and upper streets budget for grade — retaining walls, drainage, access economics — plus wildfire-zone insurance review at the open-space edges. In Sleepy Hollow, add the county-jurisdiction permit path and the single-egress evacuation awareness that comes with a one-road valley.
San Anselmo's wildfire exposure follows its wooded hillsides: the upper slopes toward Bald Hill, the ridge edges, and parts of Sleepy Hollow's open-space boundary carry elevated Fire Hazard Severity Zone designations, while the downtown flats generally do not. The Ross Valley Fire Department serves the town and Sleepy Hollow, the Marin Wildfire Prevention Authority funds county-wide vegetation management and evacuation planning, and California's AB 38 defensible-space documentation applies to sales in designated zones. Verify any address through the CAL FIRE viewer and get a written insurance quote early in escrow — on hillside and Sleepy Hollow purchases I make that sequence standard.
The three core Ross Valley towns share the watershed, the K-8 school district, the fire department, and the Drake corridor — and trade on distinctly different propositions. I maintain full guides to Fairfax and Ross as well.
San Anselmo | Fairfax | Ross | |
|---|---|---|---|
Character | The Hub town — the valley's biggest downtown and deepest housing stock | The valley's creative, outdoors-first town at West Marin's doorstep | The estate enclave — small, quiet, and closely held |
Dominant housing | Majority pre-1940: Craftsman, Tudor, Spanish revival; mid-century in Sleepy Hollow and the hills | Cottages and cabins, hillside homes, a smaller and funkier stock | Large-parcel estates and period landmarks under heritage oaks |
Shared services | Ross Valley School District (K-8, with Ross running its own K-8 district), Ross Valley Fire, one watershed, one flood program | ||
Commute anchor | Drake corridor via the Hub; Larkspur ferry ~10 min | Drake corridor over White's Hill; farthest from 101 | Drake corridor; closest of the three to Greenbrae/101 |
Flood/fire profile | Creek-corridor flood history downtown; WUI on the wooded slopes | Creek and hillside town — both maps apply | Corte Madera Creek corridor flood history; wooded WUI |
HOA / Mello-Roos | No Mello-Roos; HOAs essentially absent | No Mello-Roos; HOAs rare | No Mello-Roos; HOAs essentially absent |
Relative price position | The valley's middle — above Fairfax, below Ross, overlapping both | Generally the most attainable of the three | Top of the county alongside Belvedere |
The Hub is the junction where Sir Francis Drake Boulevard, Red Hill Avenue, and Center Boulevard meet — and it named the town's identity. In the railroad era this was the junction where the interurban lines split toward San Rafael and toward West Marin, making San Anselmo the 'Hub City' of the Ross Valley. Today it is the town's traffic reality: nearly every San Anselmo commute funnels through it, which is why I have buyers test it at 8:00 AM.
Sleepy Hollow shares the 94960 ZIP and a San Anselmo mailing address, but it is an unincorporated Marin County community — county planning governs it, not Town Hall. The valley along Butterfield Road has its own character: larger lots, predominantly mid-century ranch homes, an active community association life centered on its clubhouse and pool, Hidden Valley Elementary, and San Domenico School at the valley's end. Confirm city-versus-county jurisdiction on day one for any 94960 parcel.
It has, and the risk is the town's defining diligence item. San Anselmo Creek runs directly through downtown — some buildings were historically built out over the channel, and several have since been removed to improve flood capacity — and the New Year's Eve 2005 storm put much of the Ross Valley, including downtown, underwater. Creek-adjacent and low-lying parcels can sit in mapped FEMA zones requiring flood insurance. Check the map, the disclosures, and the flood history for any specific property.
Many Ross Valley parcels, San Anselmo included, carry a storm-drainage fee on the county tax bill funding the watershed's flood-risk-reduction program — one of several line items beyond the roughly one percent base property tax, alongside school parcel taxes and the Marin Wildfire Prevention Authority (Measure C) tax. Amounts vary by parcel and change over time, so I pull the actual tax bill for any property a client is serious about rather than estimating.
Substantially, yes. George Lucas lived in San Anselmo in the 1970s and wrote much of the original Star Wars during his years in town — and decades later he donated the bronze Yoda and Indiana Jones statues that anchor Imagination Park on San Anselmo Avenue, on land he gave the town. It is the most photographed spot downtown and a fitting emblem for a town whose creative streak long predates the franchise.
Geography and history: the town grew up around rail lines through the Ross Valley, not a highway corridor, and US-101 passes well to the east. Every drive out of town runs the Sir Francis Drake Boulevard corridor to the freeway at Greenbrae or climbs White's Hill toward Fairfax and West Marin. That structure is exactly why the town kept its scale — and why testing the Drake corridor at your actual commute hour matters more here than in any freeway town.
Plan on roughly 35 to 50 minutes to downtown San Francisco at peak — Sir Francis Drake Boulevard to US-101 at Greenbrae, then the Golden Gate Bridge — and closer to 30 off-peak. The practical alternative is the Larkspur ferry terminal, about ten minutes away, with the SMART station beside it. Golden Gate Transit buses run the Drake corridor. The Hub junction is the variable: test your actual route through it at your actual hour.
The Ross Valley School District serves grades K-8, including Brookside and Wade Thomas elementary schools in San Anselmo and Hidden Valley Elementary in Sleepy Hollow, feeding White Hill Middle School in Fairfax. For grades 9-12, students attend the Tamalpais Union High School District at Archie Williams High School — located in San Anselmo and renamed from Drake High in 2021. Private options include St. Anselm School and San Domenico School in Sleepy Hollow. Verify assignments by address via GreatSchools and the California School Dashboard.
One of Marin's most historically rich housing stocks: the majority of homes predate 1940, with Craftsman bungalows, Tudor cottages, Spanish revival, and early Victorians lining the flats and lower slopes near downtown, Yolanda, and Winship Park. Mid-century ranches dominate Sleepy Hollow and the upper hillsides, joined by view remodels and custom builds on the Bald Hill slopes. Period detail is a genuine value driver here — well-kept original homes draw their own buyer pool.
No Mello-Roos — San Anselmo has no Community Facilities Districts. HOAs are essentially absent from the single-family stock outside small condo pockets; Sleepy Hollow's community association is a neighborhood institution rather than a mandatory master HOA, though specifics vary by parcel and are worth confirming in title. The tax-bill line items to expect are the school parcel taxes, the MWPA wildfire tax, and the Ross Valley flood-control fee.
The exposure follows the hillsides: the wooded upper slopes toward Bald Hill, the ridge edges, and parts of Sleepy Hollow's open-space boundary carry elevated Fire Hazard Severity Zone designations, while the downtown flats generally do not. The Ross Valley Fire Department serves the town and Sleepy Hollow, and California's AB 38 defensible-space documentation applies to sales in designated zones. In Sleepy Hollow, factor the valley's limited egress into your evacuation-route thinking. Verify any address in the CAL FIRE viewer.
San Anselmo Avenue is one of Marin's best independent downtowns — long known as an antiques destination, anchored today by institutions like Comforts and M.H. Bread & Butter, with Creek Park and Imagination Park threading the creek through the middle of it. The event calendar carries the town's rhythm: summer music in Creek Park, the long-running Art & Wine Festival, and a genuinely used, walked-to commercial district rather than a drive-past one.
The three Ross Valley towns share the watershed, the school district pathway, and the Drake corridor — and trade on different propositions. Ross is the estate market: larger parcels, top-of-county pricing. Fairfax runs smaller, funkier, and generally more attainable, with mountain-bike culture and West Marin at its back. San Anselmo sits between them in price and character, pairing the valley's best downtown with its broadest pre-war housing stock. Most Ross Valley buyers cross-shop all three.
San Anselmo sits in Marin's sun belt — the Ross Valley is sheltered from most coastal fog, and summers run warm and reliably clear compared with the county's southern towns. The variation is parcel-level: south-facing slopes bank the light, while north-facing canyon folds run cooler and darker year-round. It is worth visiting any hillside candidate at different hours, because orientation affects both daily life and energy costs in the pre-1940 stock.
The name traces to the Mexican land-grant era, when this part of the Ross Valley was known as Cañada de Anselmo — Anselm's Valley — carrying the name of Saint Anselm. The railroad made the town: it incorporated in 1907 around the Hub junction, and the stone halls of the San Francisco Theological Seminary, crowning Seminary Hill since the 1890s, remain its most distinctive landmark — today operating as part of the University of Redlands' Marin campus.
