Initial analysis

The 14-unit, 3-story multi-family residential building at 3727 Fillmore Street in the Marina neighborhood, owned by the Fong Richard&marilyn Fam Tr, was constructed in 1928 and has undergone several significant safety improvements over the years. Most notably, the building completed its mandatory soft-story retrofit in 2017 (at a cost of $180,000) and has maintained Tier 3 compliance with a Certificate of Final Completion issued. The building has experienced persistent fire safety issues, with multiple violations related to alarm systems, fire escapes, and extinguishers between 2014-2023, though most of these have been subsequently abated. Recent fire alarm system upgrades were completed in 2021-2022, including the installation of low frequency sounders to meet current code requirements, though a violation was issued in February 2023 for unspecified alarm system maintenance issues.

The property has a documented history of various maintenance and safety violations, particularly in 2002-2014, including issues with fire escapes, exterior door security, and stair repairs, though all these violations were eventually abated. Recent building improvements include a cold water line installation in 2022 and a water storage tank replacement in 2007. The building has generated several 311 calls in the past few years, with the most recent concerns being related to sidewalk defects (2023) and a damaged tree (2021). External to the building itself, there have been recurring issues with parking enforcement and street maintenance in the immediate vicinity, though these do not directly impact the building's safety or habitability.

Risk rating

How 3727 Fillmore 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
10th percentile

Out of 988 buildings in this neighborhood, 889 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.

Building size

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

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 27.7%
Moderate concern 49.8%
Severe concern 22.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
