Initial analysis

The two-story, four-unit apartment building at 847 Castro Street, built in 1910 and currently owned by the Duncan Family 2007 Trust, has undergone several significant maintenance and improvement projects over the past three decades. Most recently, in 2019, the property completed a comprehensive bathroom remodeling project valued at $18,000, which included both plumbing and electrical work for new fixtures, lighting, and ventilation. Looking back through the building's history, there have been several key maintenance events, including reroofing work in both 2002 and 1992, structural repairs for dry rot in 1997, and termite damage remediation in 1992. Of particular note, the building underwent a series of fire safety violations in October 2011 related to flammable storage and fireproofing materials, though these issues were abated within a month by November 2011. The property has maintained regular housing inspections through the years, with records showing compliance to routine inspections in 1996, 2002, and 2007.

The surrounding area has experienced various municipal service calls in recent years, with several open and resolved cases between 2022 and 2025. Current open issues include a pavement defect (January 2025) and a property damage case (June 2024). Recent street maintenance concerns have been addressed, including garbage overflow and debris issues, while historical improvements like the 2019 bathroom remodel demonstrate ongoing maintenance efforts. The building's historical record shows consistent attention to both routine maintenance and periodic upgrades, with prompt resolution of most violations and complaints, particularly focusing on fire safety concerns in 2011. The property's documented history suggests regular upkeep of essential systems, though prospective residents should be aware of the building's age and associated maintenance history.

Risk rating

How 847 Castro St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 1278 buildings in this neighborhood, 984 are predicted to be safer.
