Sonoma Depot
Why it's listed
Located at 284 First Street West, just north of the Sonoma Plaza, this frame railroad depot dates to about 1875-76 and was built to serve the narrow gauge Sonoma Valley Railroad. It was moved from the northwest corner of the Plaza to its present site around 1890, when local citizens pressed to get the railroad off the Plaza. The redwood building has a wooden shingle roof and was originally divided into an agent's office, a waiting room and a freight area. Heavy freight scales remain inside. Trains carried cattle and basalt cobblestones for San Francisco street paving, and passengers connected to San Francisco via Sausalito. The nomination calls it a transitional example of Stick-style depot design and one of the oldest surviving depots in California. It also notes the depot's close relationship to nearby historic sites, including the Mission, Vallejo's barracks and the Plaza. The railroad stopped using it as crew quarters, and the city planned restoration.
Significance in brief: The nomination argues the depot is one of the oldest surviving railroad stations in California and a transitional example of Stick-style depot design. It symbolizes the first stage of industrial growth in rural California after railroads arrived in the 1870s. It also forms part of the historic setting near the Sonoma Plaza.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
