Initial analysis

The two-story apartment building at 839 Clayton Street, owned by Robin J Bahr, was constructed in 1904 and contains four multi-family residential units. The property has undergone several significant maintenance and improvement projects over the years, including roof replacement in 1999 (completed), front porch repairs in 2003 (completed), and installation of new siding in 2004 (completed). A notable cluster of violations was recorded in 2002, including issues with stairs, fire safety equipment, security features, and concerns about lead paint, though all were abated by March 31, 2004. A 2017 tenant complaint reported mold in a shower room and maintenance issues with stairwell lighting, which was noted as "ongoing" at that time.

The building's recent history shows consistent maintenance issues, particularly regarding stair safety and lighting. In 2015, there was a fire safety complaint about blocked exits that was promptly corrected the same day. The property has attracted significant recent attention for exterior maintenance, with ten garbage and debris reports filed between September 2024 and January 2025, though most were marked as resolved or not requiring city intervention. Three separate garbage-related incidents were reported in November 2024 alone, suggesting ongoing challenges with waste management in the immediate vicinity of the building.

Risk rating

How 839 Clayton 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
44th percentile

Out of 526 buildings in this neighborhood, 295 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 58.2%
Moderate concern 20.2%
Severe concern 21.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
