Initial analysis

The 12-unit, 3-story multi-family residential building at 1750 Washington Street in Nob Hill, built in 1913, is currently undergoing extensive renovations in Units 1, 7, 10, and 12 as evidenced by multiple active permits from December 2024 totaling over $260,000 in improvements including electrical, plumbing, kitchen and bathroom remodels, insulation, and flooring updates. The building has completed mandatory seismic retrofitting under the Soft Story program and received CFC issuance, demonstrating compliance with important safety requirements. Recent maintenance includes water heater replacement in September 2023.

The property has experienced recurring moisture and mold issues over the years, with several complaints documented between 2007 and 2018, including a significant complaint in 2015 about dampness, water in walls, and black mold throughout the building. Multiple building violations were issued in 2011 regarding combustible storage, egress obstruction, interior surfaces, and fire safety, though all were abated by July 2011. The building experienced water damage issues requiring repairs in 1999 and was brought into code compliance in 1985. Recently, there have been some miscellaneous issues reported through 311 calls, including noise complaints, flooding, and sewer-related problems in 2018, though most recent cases have been resolved. The property management appears to be actively addressing maintenance and improvement needs, as demonstrated by the current extensive renovation work.

Risk rating

How 1750 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

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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 16.2%
Moderate concern 37.0%
Severe concern 46.8%
