Initial analysis

The 7-unit, 2-story apartment building at 771 Guerrero Street, built in 1925 and currently owned by Ballestrasse Revocable Trust, has experienced several significant maintenance and safety issues over recent years. The building is currently showing multiple concerning conditions, including active complaints about peeling exterior paint (2023), ongoing building safety violations related to egress obstructions (active since 2018), and non-compliance with mandatory soft-story retrofit requirements (active since 2019). The property has faced serious habitability issues, including a documented rodent infestation affecting multiple units (2022) and previous fire safety concerns related to blocked exits (multiple incidents between 2016-2022) and storage violations.

The building's maintenance history shows attempts at addressing various structural and safety requirements, including a soft-story retrofit application (2017) and exterior wood stair repairs (2020), though many of these permits are still listed as "filed" rather than completed. Several building improvements have been attempted, including a storage room conversion in 2012-2013 and plumbing upgrades such as a backflow device installation (2015) and sewer work (2011). There have also been historical violations requiring attention to safety systems, including fire alarms, fire escapes, and combustible storage in garages (2006), though these were officially abated.

Risk rating

How 771 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.
