Initial analysis

629 Guerrero St is a three-story, 12-unit multi-family residential building constructed in 1925 and currently owned by Gerald J Shaughnessy Gst Tr. The building has undergone several significant improvements over the years, most notably completing a mandatory soft-story retrofit in 2016 (Tier 4) at a cost of $112,000. Recent concerning issues include multiple complaints in early 2024 regarding lead paint hazards during exterior work, with tenants reporting improper containment and lead testing concerns. The building's maintenance history shows attention to infrastructure, with re-roofing projects completed in 2019 ($12,000) and significant renovations to the laundry facility in 2012, including fire-rated drywall installation and plumbing upgrades. The property faced multiple building violations in 2002 related to fire safety, security, and lead paint concerns, all of which were abated by June 2002.

The building has experienced recurring fire alarm system issues, with documented complaints in 2013, 2015, 2021, and 2024, though most were resolved promptly with no reported injuries or significant incidents. The most recent boiler permit violation complaint from March 2023 remains active. Historical maintenance records indicate attention to structural elements, including repairs to stairs and exterior woodwork in the early 2000s, and compliance with various building codes. The property has also maintained a routine inspection schedule, with the last significant inspection-related complaints being addressed by 2024. While the building has generally complied with major safety requirements, the recent lead paint concerns during exterior work and the active boiler permit violation require particular attention.

Risk rating

How 629 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
