Initial analysis

The two-unit residential building at 977 Clayton Street, owned by David E Vanderbilt 2013 Rev, is a three-story flats and duplex structure built in 1910 in the Parnassus/Ashbury Heights neighborhood. The property's most significant recent maintenance work was a complete roof replacement in 2017, costing $14,500, which was conducted as an in-kind replacement without changes to the original roof form. Other notable improvements include a 2011 plumbing upgrade that involved replacing a 4-inch clean-out with a new 6-inch clean-out and sidewalk repairs, as well as a deck repair project from 1994 that replaced planking and rails. Two street space and sidewalk permits were issued in 2011 and 2004, and there was a cancelled permit for a one-story detached garage construction in 1990.

The property has experienced recurring issues with abandoned vehicles in the vicinity, particularly during 2017 when multiple reports were made between February and June, though all vehicles in these cases were gone upon inspection. The most recent building-related incident was a general cleaning complaint regarding loose garbage in November 2018, which was resolved. Historical permits from 1981 and 1990, as well as multiple failed vehicle removal attempts from 2016 through 2018, are also on record. The building appears to be regularly maintained, with the most substantial work focusing on essential systems like the roof and plumbing infrastructure.

Risk rating

How 977 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
76th percentile

Out of 526 buildings in this neighborhood, 126 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 location

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

Building age

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

Construction spend, owner's portfolio

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

12-Month severity forecast
No violation 78.2%
Moderate concern 13.8%
Severe concern 8.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
