Initial analysis

The property at 1243-1245 Guerrero Street is a two-story, four-unit multi-family residential building located in the Noe Valley neighborhood, constructed in 1900 and currently owned by the Nancy Hua 1998 Revocable Trust. The building has undergone several significant electrical upgrades in recent years, with complete rewiring projects in units 3 and 4 in 2022-2023, including the removal of outdated knob and tube wiring and installation of new subpanels. The building's maintenance history shows recurring attention to safety features, particularly regarding stairs and decks, with handrail installations and structural repairs being addressed multiple times between 1988 and 2010, most recently in 2010 when handrails were installed at rear stairs to comply with a notice of violation.

The property experienced a cluster of violations in 2010 that required attention to various safety systems, including fire escape ladders, fire extinguisher maintenance, and stair repairs, all of which were eventually abated. The most recent building violations occurred in March 2017, which were promptly resolved within one month. Recent maintenance activity includes gas houseline extensions in 2009 and routine tree maintenance in 2020-2021. The building has had multiple routine inspections documented over the years, with the most recent inspections focusing on various building systems and safety features. A minor fire complaint in 2015 was resolved on the same day with conditions corrected. Recent 311 calls from 2023 primarily relate to temporary construction-related issues and street maintenance matters outside the building's immediate scope. While the building has had periodic maintenance and safety issues over the years, recent improvements, particularly the complete electrical upgrades and prompt resolution of violations, suggest ongoing attention to maintaining the building's safety systems and infrastructure.

Risk rating

How 1243-1245 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.
