Initial analysis

The three-unit residential building at 512 Oak Street in Hayes Valley, owned by Demonsant Benoit, was constructed in 1900 and is classified as a two-story flats and duplex structure. The property has undergone several significant improvements in recent years, with the most recent works in 2023 including the installation of two new fireplaces with associated gas lines and electrical wiring, and the replacement of the sewer lateral. The building has seen substantial modernization efforts, most notably a comprehensive 3rd-floor interior remodel in 2013 that included bathroom renovations, closet modifications, and laundry relocation, along with window replacements in 2014 and 2015. An important safety modification occurred in 2016 with plans to replace a non-compliant wood winder stair, though this permit was ultimately cancelled.

The building's maintenance history shows attention to both safety and comfort, with regular updates to comply with current building standards. Historical records indicate some previous issues that were resolved, including a cluster of interior surface violations related to wall repair, painting, and lead hazard mitigation in 2002-2012, and a complaint about poor insulation in 2013. The property has undergone routine safety inspections by Housing Inspection Services in 2002, 2003, 2009, 2012, and 2019, with all issues being addressed and closed. Recent 311 calls from 2018-2024 primarily relate to street cleaning matters and routine municipal services, suggesting no current building-specific issues. The most recent permits and work completed demonstrate ongoing investment in the property's upkeep and improvement, particularly in enhancing resident comfort through the installation of modern fireplaces and associated amenities.

Risk rating

How 512 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, 298 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.

No violation 49.9%
Moderate concern 19.4%
Severe concern 30.7%
