Initial analysis

The 6-unit, 2-story multi-family residential building at 1426-1428 Guerrero Street in Noe Valley, built in 1890 and currently owned by Ballinree LLC, has undergone several significant maintenance and safety improvements over the past few decades. Most recently, in early 2023, the building completed repairs to exterior stairs at the rear, including the installation of handrails to address safety compliance requirements, and electrical improvements involving panel cover replacements and restoration of panel clearances. A health and safety inspection in late 2022 prompted these stair repairs, though this was the only active complaint in recent years. The building has a documented history of maintenance work, including a 2010 water service replacement, kitchen and bathroom renovations in unit D in 2012, and previous structural work such as foundation repairs in 1991 and kitchen cabinet replacements in 1988.

The building experienced notable issues in the early 2000s, including a series of violations in 2001 related to plumbing, electrical, security, and interior surfaces that were all abated by July 2002, as well as complaints concerning rodent problems, water damage, and inadequate heating. Two plumbing-related incidents were reported in 2006, though these were promptly addressed. The property has maintained active compliance with building codes since the resolution of the 2001-2002 violations, with no active complaints or violations on record since 2023. Recent 311 calls primarily relate to external issues such as street cleaning and parking enforcement, with no reported impact on resident safety or building conditions. A single cooking-related fire incident was recorded with no civilian injuries, though no specific date or further details were provided.

Risk rating

How 1426-1428 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.
