Initial analysis

The 12-story multi-family residential building at 901-945 Sacramento Street, owned by Mei Lun Yuen, was constructed in 1982 and contains 185 units. The building has undergone numerous significant maintenance and safety upgrades in recent years, including a generator replacement project in 2023 ($1.1 million), installation of a remote fuel fill system for the rooftop generator in 2022 ($110,000), and comprehensive fire safety system improvements. A notable commitment to safety was demonstrated in 2023 with sound level inspections conducted in sleeping areas to comply with San Francisco Fire Code requirements. The building has experienced multiple fire code violations over the years, with the most recent violation issued in October 2023 regarding sleeping area requirements, though many previous violations have been successfully abated.

The property has undergone substantial infrastructural improvements, including the replacement of two 200-gallon water storage tanks (November 2023), new domestic hot water boiler installation (March 2023), and various bathroom renovations to improve accessibility in Unit 201 (2022), which included barrier removal and fixture updates. The building's fire safety systems have been actively maintained and upgraded, with recent work including fire pump replacement (2019), fire alarm system enhancements (2019), and multiple backflow preventer installations (2021). There were two resident complaints in April 2020 regarding construction noise and odors during the shelter-in-place period, which were promptly investigated, and historical violations related to the fire escape drop ladder and central alarm system in 2005 were resolved within weeks.

Risk rating

How 901-945 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.

Neighborhood percentile
29th percentile

Out of 1125 buildings in this neighborhood, 799 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 26.4%
Moderate concern 71.6%
Severe concern 2.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
