Initial analysis

The 15-unit, three-story multi-family residential building at 3750 Scott Street in the Marina neighborhood, owned by the Yuen Family Trust, was constructed in 1929 and has undergone several significant safety and infrastructure upgrades over its lifetime. Most notably, in the past four years, the building has seen substantial fire safety improvements, including the replacement of the wired fire alarm system with wireless sounders in all sleeping areas to comply with current fire code requirements. Additional recent improvements include the installation of a new water heater and storage tank in 2019, and a solar power system installation in 2018. The building has maintained regular upkeep of essential systems, as evidenced by historical records showing window replacements in 2010, foundation work in 1990, and roofing work in 1990, all of which were properly completed.

The building's maintenance history reveals past compliance issues that have been addressed, including multiple fire safety violations in 2001-2010 related to fire extinguishers, smoke detection systems, and egress concerns - all of which were subsequently abated. More recent fire safety complaints from 2017-2023 regarding exit maintenance and alarm systems were also corrected. The property has experienced periodic service calls for various maintenance issues, with the most recent 311 calls in 2024 primarily relating to street cleaning matters. The building's records demonstrate an ongoing commitment to addressing safety concerns, as evidenced by the prompt resolution of both building violations and fire complaints. The most recent fire safety upgrades, including the installation of wireless sounders and modern solar power system, suggest proactive management of the building's infrastructure and compliance with contemporary safety standards.

Risk rating

How 3750 Scott 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 988 buildings in this neighborhood, 800 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 22.0%
Moderate concern 68.1%
Severe concern 9.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
