Initial analysis

The three-story, nine-unit multi-family residential building at 2140 Vallejo Street in Pacific Heights, owned by the James H Thorne Revocable Trust, has undergone significant improvements and maintenance since its construction in 1900. Most recently, in 2023, Unit 8 received a new roof ($21,000), and Unit 7 completed kitchen and bathroom renovations ($38,000) with associated electrical and plumbing updates. The building successfully completed its Tier 3 Soft Story retrofit requirements, demonstrating adherence to seismic safety standards. Historical records show a pattern of unit improvements, including substantial renovations in Units 5, 7, and 8 between 2016-2022, with all work generally following proper permit procedures.

The property has experienced some safety and maintenance challenges over the years, particularly evident in older violation records from 1997-1999, which documented issues with wiring, plumbing, ventilation, fire safety, and pest problems. However, these problems were addressed and resolved, with the building maintaining active compliance with current safety standards. Most recently, in late 2024, the building underwent sprinkler/standpipe system and alarm system inspections, with the sprinkler issue being corrected promptly. The property has also received attention to its exterior and surrounding area, with multiple 311 service requests in recent years primarily related to street cleaning and maintenance. While occasional issues have been noted in recent years regarding fire safety systems and exterior maintenance, these have generally been addressed promptly through proper channels.

Risk rating

How 2140 Vallejo 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
23th percentile

Out of 963 buildings in this neighborhood, 742 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 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 69.2%
Moderate concern 11.6%
Severe concern 19.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
