Initial analysis

1623 Vallejo St is a 4-unit, 3-story multi-family residential building located in Pacific Heights, constructed in 1900 and currently owned by Chris Hui. The building has undergone several significant renovations and repairs over the past two decades, including substantial improvements in 2005-2006 when the kitchen and bathroom were remodeled, and a second floor dining room conversion was performed. Prior to this, in 2003, comprehensive updates were completed including bathroom renovations, window replacements, and electrical system upgrades including a new 200-amp service installation with five meters. The building's maintenance history shows attention to both structural and safety systems, with roofing work done in 1999 and dry-rot repairs in 2002.

Of particular concern is the recurring sewage issue, with multiple incidents reported between 2020-2024, including several sewage backup incidents involving 4-inch vents and catch basins. The most recent events occurred in March, August, and October of 2023. The building has also experienced some safety system challenges, most notably in October 2009 when fire extinguisher maintenance and central alarm system repairs were required, though these violations were abated within weeks. A potentially concerning active complaint from 2001 remains on record regarding electrical issues including sparks from outlets and window malfunction. The property has had regular electrical system updates, including the replacement of painted wall outlets and light fixtures in 2003, and a bathroom electrical remodel in 2005, suggesting ongoing attention to electrical safety.

Risk rating

How 1623 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

Out of 963 buildings in this neighborhood, 433 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 38.3%
Moderate concern 12.3%
Severe concern 49.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
