Initial analysis

The three-unit residential building at 461 Oak Street in Hayes Valley, built in 1900, has undergone several significant improvements and faced some challenges over the past two decades. The most recent maintenance work involved repairing rot in front exterior stairs in 2018, while recent 311 calls in 2024 primarily concerned street cleaning issues. The building underwent important safety improvements in 2013, including voluntary seismic strengthening, and received significant electrical system upgrades in 2006. Several unit renovations were completed between 2006-2008, including kitchen and bathroom remodels, though there was a notable complaint in 2012 regarding unpermitted renovations in one unit that affected others. The building has a history of addressing moisture-related issues, with multiple violations and complaints regarding water damage and ceiling repairs in 2002, all of which were abated by May 2002. Two fire incidents were recorded, both related to alarm system or smoke detector activations with no injuries or actual fires reported.

The property underwent an important clarification of its unit count in 2007 to officially acknowledge the three residential units. While there have been no active violations since 2012, the building's recent permit history shows regular maintenance and repair work. The street outside the property has required periodic cleaning as evidenced by multiple 311 calls in recent years, but these relate to public space rather than building conditions. The building's major systems (including fire safety) have received attention over the years, with the installation of a comprehensive fire alarm system in 2003 and subsequent maintenance to address various building elements.

Risk rating

How 461 Oak 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 1027 buildings in this neighborhood, 401 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 43.1%
Moderate concern 15.5%
Severe concern 41.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
