About This Home

As of August 2025

Two historic turn-of-the-century heritage homes on a single 10,426sf lot in the heart of downtown Petaluma. Architect Brainerd Jones (1865-1949) was commissioned by the Cavanagh family in 1902 to build 10 Keller Street. An impressive Georgian Revival mansion was one of Brainerd's earliest commissions, towering 3 stories, 4124sf, 5 bedrooms each with ensuites, and 7 bathrooms. Two formal parlors and dining room with original brass chandeliers intact. Stunning original artisan redwood millwork, including a majestic foyer, hardwood floors, ceilings, hand-carved columns, staircase, and fireplaces. Adjacent #8 Keller Street circa 1912 shingled craftsman cottage. 3 bedrooms, 3baths, 2040sf, 2 stories, enclosed front porch, fireplace, and original redwood details throughout. A storied history from the Cavanagh family home to the Cavanagh Inn Bed & Breakfast. An ornate deck and staircase, views of Brainerd Jones's finest architectural commissions include the adjacent schoolhouse, McNear Building & Mystic Theatre. A grand Persimmon tree anchors the backyard lawn and gardens. Don't miss this opportunity to cherish the history of days gone by, the epitome of turn-of-the-century workmanship, and the architectural significance of a Brainerd Jones masterpiece.
