Initial analysis

The three-story, six-unit apartment building at 1129-1133 Guerrero Street in Noe Valley, built in 1908, has undergone significant recent renovations totaling approximately $45,215 in 2023, including kitchen and bathroom upgrades such as new cabinets, countertops, sinks, light fixtures, and shower enclosures. The property has also experienced some concerning history, particularly in 2020 when it suffered multiple sewage backup incidents involving 4-inch vents, with at least eight calls to PUC Sewer Operations between September 8 and September 30, 2020. In 2023, there was a building complaint regarding unpermitted construction work that raised concerns about potential water, gas, and fire issues, though this was abated within two months. The building's maintenance record shows various improvements, including electrical upgrades (replacement sub-panel and new outlets/lights) and plumbing work (kitchen and bathroom fixture replacements).

Historical records from the building reveal some safety and maintenance issues that have since been addressed, including multiple violations in 2000-2001 related to building security, smoke detection, and structural concerns, all of which were abated by November 2000. There was also a significant plumbing violation involving bathroom mold and decay issues in 2000, though this was resolved within three months. More recently, in 2021, there were complaints about insufficient heat, and a routine inspection in 2006-2007 noted various maintenance issues. The building's infrastructure has received attention over the years, with documented work including a gas line rough-in in 2021 and various electrical and plumbing upgrades in 2023. A fire-related incident occurred in 2022 involving a smoke detector malfunction, but no injuries were reported. The property has maintained active response to infrastructure needs, as evidenced by the extensive recent renovations and prompt attention to maintenance issues when they arise.

Risk rating

How 1129-1133 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.
