Initial analysis

The multi-family residential building at 457-461 Guerrero Street in Mission Dolores is a three-unit, three-story structure built in 1907 and currently owned by the Lee Family Trust. The building's maintenance history shows significant plumbing work was completed in May 2014, involving the replacement of gas pipes for unit 457 and the garage areas serving units 459 and 461. A routine housing inspection was conducted in June 1999, which was resolved the following month. The property has experienced several street-level sanitation issues in recent years, with multiple 311 calls between 2019 and 2025 reporting instances of garbage, debris, and human waste on public sidewalks, though all these cases were marked as resolved. There have been two parking enforcement incidents documented in 2019 involving blocked driveways, one resulting in a citation. Street use permits were issued in 2012, and there were two minor fire-related incidents reported, though neither involved civilian injuries. While the building's interior condition remains largely undocumented through these records, the frequency of street-level sanitation issues around the property suggests ongoing environmental management challenges in the immediate vicinity, particularly regarding waste management and sidewalk maintenance.

Risk rating

How 457-461 Guerrero 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
28th percentile

Out of 799 buildings in this neighborhood, 575 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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

DBI complaints, owner's portfolio

Complaints across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 55.8%
Moderate concern 34.1%
Severe concern 10.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
