Initial analysis

The 6-unit, 3-story apartment building at 552-562 Vallejo St in Telegraph Hill, owned by Andrew Fong & Betty Woo Cho, has undergone several significant improvements since its construction in 1906. Most notably, the building completed a mandatory soft-story retrofit in 2017 (Tier 3) at a cost of $135,000, demonstrating compliance with seismic safety requirements. Recent maintenance includes the replacement of the house trap for units 552-554 in April 2022, installation of a new gas line and water heater in the laundry room in 2010, and conversion of the retaining wall at the rear of the building in 2007.

The building has maintained active compliance with housing codes, though it experienced several violations in 2005 related to safety concerns such as wooden stairs, egress obstructions, and smoke detector issues, all of which were resolved by July 19, 2005. A lead paint issue was noted in 2015 and resolved by June 11, 2015. Recent 311 calls indicate ongoing maintenance needs in the area, with the most current issues being a tree maintenance concern (property damage) as of January 2025, and various parking enforcement matters between March 2024 and December 2024. The building's infrastructure has received regular attention over the years, with records showing reroofing work in 2005, sheetrock replacement in the laundry room and kitchen repairs in 2002, and multiple street space permits.

Risk rating

How 552-562 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
21th percentile

Out of 684 buildings in this neighborhood, 540 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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.

12-Month severity forecast
No violation 46.8%
Moderate concern 42.0%
Severe concern 11.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
