Initial analysis

The 27-unit, 3-story apartment building at 1170 Guerrero Street in Noe Valley, owned by Crl Survivors Trust, has undergone significant safety and maintenance improvements over recent years. Most notably, a fire alarm system upgrade was initiated in late 2023 to enhance safety compliance, replacing the existing system with SK-6808 with radio capabilities, new smoke detectors, pull stations, and low-frequency sounders in sleeping rooms at a cost of $77,179. In 2016, the building completed mandatory soft-story retrofit work at a cost of $214,000, demonstrating compliance with seismic safety requirements. The property has experienced several maintenance upgrades, including window replacements, electrical system improvements, and plumbing repairs. A notable fire incident occurred in 2014 (Unit 108), resulting in repairs to walls, ceilings, and plumbing systems.

Recent electrical upgrades have included replacing 15 fuse boxes with breaker boxes (2020-2021), installing exit signs and emergency lights (2019), and completing a substantial upgrade to underground electrical service to 400A with individual unit meters, which was issued in April 2024. The building has faced various operational challenges over the years, including elevator maintenance issues (2008-2015), plumbing problems, and water damage concerns. Several violations were recorded in 2001 related to fire safety, including issues with fire escape maintenance and smoke detectors, though these were abated by September 2001. The most recent fire code violation regarding sleeping area requirements remains open as of November 2023, while prior emergency lighting violations from 2019 have been resolved. The property has a history of addressing maintenance issues promptly, as evidenced by the completion of various repair and upgrade projects, including the installation of new hot water tanks (2012), sewer line work (2011), and multiple electrical system improvements.

Risk rating

How 1170 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.
