Initial analysis

The three-story multi-family residential building at 2525-2529 Polk Street in Russian Hill, owned by Northwest Heritage SF LLC, was constructed in 1904 and contains 6 units. The property has recently undergone significant fire safety upgrades, with completed permits in February 2024 for a fire alarm system upgrade costing nearly $29,000, including the installation of low-frequency sounders in sleeping areas to comply with current fire code requirements.

The building has maintained a relatively clean safety record over the years, with no civilian injuries reported in any of the fire incidents recorded. These incidents have primarily involved false alarms or system malfunctions, with only two cases of water-related issues. The property has undergone routine housing inspections in 1999, 2003, 2006, and 2011, all of which were promptly addressed. Recent maintenance activity has focused on exterior cleanliness, with several 311 calls between 2023-2024 regarding street and sidewalk cleaning, including reports of debris, waste, and abandoned items. While these street-level issues have been consistently addressed and marked as resolved by various city agencies, they primarily relate to public space maintenance rather than building-specific concerns. The most recent building-related activity was a zoning verification request in 2023, which was marked as closed and issued.

Risk rating

How 2525-2529 Polk 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 1133 buildings in this neighborhood, 600 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.

Neighborhood (ZIP code)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 56.1%
Moderate concern 19.6%
Severe concern 24.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
