Hidden at the end of a private drive, tucked away from the everyday, sits a true relic of old Petaluma and one of its most unique offerings in recent memory. Set on 4.2 acres of open, usable land, this 1890 farmhouse is the kind of property that stops you in your tracks. At approximately 900 square feet, the home lives larger than its footprint thanks to soaring ceilings in the living room and both bedrooms a hallmark of the era it was built. Enduring character: original charm, hardwood floors, and the warmth of a home that has been loved and well cared for across generations. Outbuildings dot the property in true working-ranch fashion weathered, photogenic, and full of possibility. Whether you’re dreaming of a hobby farm, a rural creative retreat, or simply a place to exhale, the land invites it all. What makes this property truly rare is its R4 zoning representing significant development potential for those with vision. A piece of Petaluma’s history, hiding in plain sight. Properties like this don’t surface often and they don’t last when they do.
