House hacking in Santa Rosa (Downtown / Railroad Square).

Sonoma County's premier rail-transit ZIP: an adopted downtown upzone wrapped around an in-ZIP SMART station, at a price well under anything comparable in Marin.

What's actually happening in 95404

  • Adopted upzoning

    Downtown Station Area Specific Plan (adopted Oct 2020, EIR certified): raised the 10-story height cap, cut parking minimums, added FAR bonuses. Railroad Square is a named core subarea. City of Santa Rosa DSASP

  • Operational

    SMART Downtown/Railroad Square station in-ZIP (7 Fourth St), with Transit Mall connections a quarter-mile east across a Hwy-101 pedestrian gap. SMART

  • Mixed: delivered through proposed

    Delivering pipeline: Stewart Cannery (128 affordable units, opened May 2025), 425 Humboldt (8-story, 95 units, proposed), Cornerstone Downtown, and ~300 apartments with a developer selected. City of Santa Rosa development pages

  • Existing anchors

    Jobs base in or near the ZIP: Kaiser Santa Rosa (~2,555), Sutter Santa Rosa (~1,797), Providence Memorial, SRJC. Citywide target of 4,685 units by 2031. City of Santa Rosa

The house-hack angle

Walkable room-by-room or small multifamily near the station, working the older downtown and Railroad Square stock. The Historic District adds design review on some parcels.

What breaks it

  • Hwy-101 pedestrian severance between the station and the Transit Mall
  • Historic-district design review friction on Railroad Square parcels
  • Confirm the parcel sits on city flats (insurable), not the Fountaingrove seam
