Initial analysis

The three-unit, two-story multi-family residential building at 1250 Guerrero Street in Noe Valley, owned by William & Ernestina Guaiumi, has undergone several significant maintenance and improvement projects since its construction in 1987-1989. Most recently, in July 2023, the building received a new roof (cost: $15,000) and underwent garage repairs involving the replacement of 130 square feet of water-damaged drywall (cost: $5,500). The building's history includes one notable cluster of violations in 2001 related to fire safety and security, requiring the removal of obstructions from fire escapes and installation of proper door viewers; however, these issues were promptly resolved within a month. The property has undergone routine housing inspections in 2001 and 2006, with no recorded violations from the most recent inspection.

The building's exterior and surrounding area have experienced various maintenance issues in recent years, with multiple reports of garbage and debris on the street (five incidents reported between January to August 2024), and some infrastructure concerns including a lifted sidewalk (February 2024) and a damaged tree (August 2023), all of which were addressed by respective city agencies. There was also one instance of parking enforcement requested for a blocked driveway in May 2024, though the responding officer was unable to locate the vehicle. The building's permit history shows proper maintenance and upgrading of facilities, including the original installation of fire sprinklers and construction of additional bathroom facilities, indicating ongoing compliance with safety requirements.

Risk rating

How 1250 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 1879 buildings in this neighborhood, 921 are predicted to be safer.
