San Anselmo sits in the heart of Ross Valley, where charming Craftsman bungalows and mid-century ranches line streets that slope down toward San Anselmo Creek. It's a beautiful place to own a home — until the creek reminds you it was here first.

Nearly half of San Anselmo properties face serious flood risk. Combine that with housing stock where 30% of homes predate 1939, and you're looking at foundation challenges, drainage issues, and structures that were built decades before modern seismic codes existed. This isn't a town where you hire the cheapest contractor and hope for the best.

Local Insight

Building in a Flood Zone

San Anselmo Creek has flooded repeatedly, placing 46% of local properties at risk. Foundation work here must account for water table fluctuations, proper drainage, and flood-resistant materials. We design every foundation and retaining wall to manage water — not just hold dirt.

What San Anselmo's Weather Does to Your Home

San Francisco's housing stock punishes exterior finishes. Fog-belt neighborhoods like the Sunset and Richmond sit in a permanent moisture envelope — Doelger rowhouses from the 1930s–50s with their stucco-over-shiplap sheathing are the classic failure case, where water finds every missed kickout flashing around bay windows. Victorian and Edwardian homes carry their own dry rot risks at cornices, bay trim, and ground-floor water tables. We've repaired stucco, dry rot, and siding on every housing type this city has built.
