Initial analysis

The three-story, five-unit multi-family residential building at 4475-4477 Mission Street in the Excelsior neighborhood, owned by Diane L Szucs Trust 2002 and constructed in 1930, has undergone several significant safety and infrastructure improvements over the past two decades. Most notably, in 2021, the building received an important fire safety upgrade with the installation of eight low-frequency sounders in sleeping areas and associated electrical work to bring the fire alarm system into compliance with SF Fire Code requirements. The building has also undergone routine maintenance and safety improvements, including the installation of an exterior stairwell handrail in 2010 to address a citation, though this work was part of a broader set of repairs required due to multiple housing inspections.

The property has experienced a series of housing inspections between 1999 and 2010, with several violations documented and subsequently resolved, including issues related to fire safety systems, stairway conditions, and painting requirements. A notable incident occurred in 2004 involving a rooftop fan system that was allegedly blowing grease onto an adjacent property, which was resolved within two months. More recent records from 2024 show numerous parking enforcement calls and some minor building maintenance issues, including garbage debris reports and a graffiti complaint, though these do not appear to indicate any significant safety concerns. The building's fire alarm system has experienced periodic malfunctions, with documented service calls in 2020, but no injuries or major incidents have been reported.

Risk rating

How 4475-4477 Mission 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 337 buildings in this neighborhood, 286 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 location

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

Building size

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

12-Month severity forecast
No violation 29.9%
Moderate concern 30.5%
Severe concern 39.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
