Initial analysis

The Mui Family Trust owns this three-unit, three-story multi-family residential building located at 577-581 Guerrero Street in Mission Dolores. Built in 1907, this flats and duplex structure has undergone several maintenance and improvement projects over the years, with the most recent significant work occurring in 2014 when the rear wall siding was repaired/replaced at a cost of $2,000. Earlier repairs included back stair repairs in 2007 and various maintenance tasks in previous decades, including roofing work in 1994 and code compliance improvements in 1986. The building has experienced multiple rodent infestations, with documented cases in 2010 and 2011, and faced several fire safety issues in 2010 including combustible storage and fireproofing problems, all of which were abated by late October 2010.

The property has a documented history of maintenance challenges related to building systems and resident comfort, including a 1999 complaint about inadequate heat, cracked windows, and poor electrical systems that remains listed as "Active." More recent building maintenance issues appear to be minimal, with only routine inspections and normal urban challenges such as graffiti and sidewalk blocking reported through 311 calls. The most recent complaint was regarding construction equipment blocking the sidewalk in August 2023, which was resolved with no defects found. The building's maintenance history shows regular attention to structural elements and safety systems, though there were periods of more significant infestations and safety concerns in the late 2000s that required multiple interventions to resolve.

Risk rating

How 577-581 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

Out of 799 buildings in this neighborhood, 304 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.

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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 48.6%
Moderate concern 17.6%
Severe concern 33.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
