AI summary

The 546-548 Vallejo Street property, located in Telegraph Hill and owned by the Mar/sung Family Trust, is a two-story, three-unit multi-family residential building constructed in 1906, originally featuring a garment factory on the ground floor. The building has undergone significant modernization work between 2017-2018, including the installation of a radiant heat system, comprehensive electrical rewiring with new subpanels and safety features, and extensive plumbing upgrades for multiple bathrooms, kitchens, and laundry facilities. The property previously had a garage area that was converted from a commercial space, with approved plans for a foundation replacement and garage modifications.

Most recently, there is an active emergency response inspection case from January 2025 regarding structural damage to the east side of the garage, front entry stairs, and security gate, following a vehicle collision with the building. The property has experienced recurring issues with debris and furniture on the street (October-December 2024), as well as some instances of graffiti and parking violations. Multiple street space permits were issued in 2017, and the building underwent various infrastructure improvements including bathroom renovations, heating system updates, and electrical system modernization. The installation of new safety features such as smoke detectors and the conversion from furnace to radiant heat system demonstrates ongoing efforts to improve resident comfort and safety.

Risk rating

How 546-548 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
55th percentile

Out of 684 buildings in this neighborhood, 308 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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 64.3%
Moderate concern 28.1%
Severe concern 7.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
