Initial analysis

The three-story multi-family residential building at 1418-1420 Polk Street, owned by Kent & Debbie Hiura Revoc T, was constructed in 1911 and contains five apartment units. The building has undergone several important maintenance and safety improvements over the past few decades, including a reroofing project in 2000 costing over $12,000, and a water pipe replacement from the meter to the building's main shut-off valve in 2015. A significant cluster of building violations was recorded in February 2003, particularly related to safety concerns, including problems with egress obstructions, floor drain covers, fire extinguisher maintenance, and the central alarm system. These violations were all properly addressed and abated by August 2005.

More recent history shows the building experienced a fire alarm malfunction (735) with no civilian injuries recorded. Between October 2023 and December 2024, there has been a notable pattern of street and sidewalk maintenance issues near the property, including multiple reports of human waste and general debris requiring cleaning. A sidewalk defect was reported in March 2024, though this case was closed due to missing information. The property's historical maintenance record shows periodic attention to basic infrastructure needs, though the frequency of recent sanitation-related 311 calls suggests ongoing challenges with the immediate vicinity's upkeep, particularly regarding waste management and sidewalk conditions.

Risk rating

How 1418-1420 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 448 buildings in this neighborhood, 67 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 55.4%
Moderate concern 21.2%
Severe concern 23.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
