Initial analysis

Located in the Buena Vista Park neighborhood, this 2-unit multi-family residential building at 1136-1138 Clayton Street was built in 1917 and is currently owned by the Nicole S Cosgrove Revocable Trust. The property underwent significant renovations between 2008-2009, including a major $170,000 project that added a new garage, excavated basement area, constructed a rear deck, and renovated bathrooms in both units. Additional improvements from that period included kitchen renovations, window replacements, and various electrical and plumbing upgrades, such as the installation of four new bathrooms, a new central heating system, and comprehensive electrical rewiring with smoke detector installations throughout.

The building has experienced several maintenance and safety-related incidents over its history, including a 2009 electrical complaint regarding hazardous conditions and energy use, which was promptly addressed within weeks. Earlier issues included mold and maintenance concerns noted in a 2008 housing inspection, though these were also resolved. More recent history shows no major building-specific complaints or violations since 2009. The property has had multiple street cleaning and parking enforcement calls in the vicinity over the past year, particularly concerning illegal parking and driveway blocking, though these appear to be consistent with general neighborhood challenges rather than building-specific issues. The most recent building-related service requests have primarily concerned street cleaning and parking matters rather than structural or maintenance issues.

Risk rating

How 1136-1138 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
61th percentile

Out of 351 buildings in this neighborhood, 137 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.

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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 67.1%
Moderate concern 19.8%
Severe concern 13.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
