Initial analysis

The three-story, multi-family residential building at 1624-1630 Washington Street in Nob Hill, built in 1909, has undergone significant improvements and renovations over recent years under the ownership of Washington At Polk LLC. Major safety upgrades were completed in 2021, including the installation of a comprehensive fire sprinkler system throughout the ground floor and a new fire alarm system with sprinkler monitoring capabilities, representing a commitment to resident safety. The building underwent substantial unit improvements in 2020-2021, including an interior expansion of the ground floor unit adding three bedrooms and two bathrooms, window replacements throughout (including 21 windows not facing the street), and the installation of new HVAC systems with 95% efficient furnaces for all four units.

The property has a documented history of tenant buyouts in 2019-2020, with amounts varying from approximately $46,000 to $199,900, totaling over $430,000 for at least eight tenants across different units. In early 2020, there were multiple complaints regarding construction work, including dust issues and concerns about structural safety, though these were eventually abated. The building's systems have been systematically updated, including electrical upgrades with new wiring and panels, plumbing improvements including sewer pipe replacement, and comprehensive unit remodeling involving kitchen and bathroom updates. More recently, there have been noise complaints filed in October 2024, currently listed as open cases. The property's planning records indicate conversions of some units from traditional dwellings to "Group Housing" status, with a total of 14 bedrooms permitted within the group housing units, though this change was documented to comply with San Francisco planning code requirements.

Risk rating

How 1624-1630 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
