Initial analysis

The 6-unit, 4-story apartment building at 1745 Washington Street in Nob Hill, built in 1917 and currently owned by Derek Wong, has experienced several significant maintenance and safety concerns over the past quarter-century. Most recently, in early 2024, there were issues with leaks in the entryway and ceiling problems, while a concerning pattern emerged in 2020 with reported lead paint hazards, structural damage, and rodent feces. The building underwent mandatory seismic improvements as a Tier 3 Soft Story retrofit between 2017 and 2019, involving shear wall and footing relocations, which have now been completed and properly permitted. A 2018 fire alarm system violation was issued and subsequently abated, though there have been two water-related emergencies recorded by the fire department with no civilian injuries reported.

The property has a documented history of maintenance challenges, particularly evident during a series of violations in 2001-2002, which included issues with fire safety equipment (fire extinguishers and escape ladders), security (exit door locks), plumbing/electrical systems, and lead paint concerns. These violations were eventually abated by September 2002. More recent concerns include a 2024 flooding incident documented through 311 calls, as well as various exterior maintenance issues such as graffiti, sidewalk cleaning needs, and debris removal requests. The building's inspection history shows regular oversight by Housing Inspection Services, with some routine inspections showing persistent maintenance issues worth noting, including a documented hole in the ceiling of the entryway and historical references to stair repairs needed in 2004.

Risk rating

How 1745 Washington 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

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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

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.

12-Month severity forecast
No violation 18.6%
Moderate concern 38.3%
Severe concern 43.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
