Initial analysis

The three-story, 9-unit apartment building at 1441-1447 Sacramento Street in Nob Hill, owned by David C & So Ying Wong Family, has undergone several significant safety improvements over the past few years. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $120,000, bringing it into compliance with San Francisco's seismic safety requirements. Recent plumbing work has included a complete replacement of the sewer lateral and house-trap in October 2022. However, there have been recurring issues with the building's fire safety systems. Most recently, in October 2024, violations were documented for blocked exits and missing fire extinguishers, though these conditions were corrected by November 2024. This followed a similar pattern from 2001 when fire safety violations were recorded and subsequently abated, as well as a 2006 incident involving alarm systems. The building has also experienced multiple sewer-related issues in 2023, with three separate incidents of flooding or sewage backup reported between March and April 2023, suggesting potential ongoing infrastructure challenges. On the positive side, the property has maintained its soft-story retrofit compliance status as "Work Complete, CFC Issued." Recent reports show regular parking enforcement activity around the property, with several citations issued for blocked driveways between 2023 and 2024.

Risk rating

How 1441-1447 Sacramento 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.

Model explanation

What's driving this score

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.

Neighborhood (ZIP code)

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

12-Month severity forecast
No violation 14.3%
Moderate concern 39.2%
Severe concern 46.5%
