Initial analysis

The property at 1021-1023 Guerrero Street is a two-story multi-family residential building located in Noe Valley, containing four units and constructed in 1879. The building underwent significant renovations between 2007-2008, including comprehensive interior remodeling of the second and third floors involving kitchen relocations, bathroom additions, and stair reframing to meet code requirements, with associated electrical, plumbing, and roofing work totaling approximately $376,000. While the main renovation project was successfully completed, there was a notable permit compliance issue where one of the building permits (200802295963) was cancelled, leading to violation proceedings in 2009 that were ultimately abated in 2010. During the renovation period, there were some construction-related complaints regarding debris and scaffolding, though these were resolved promptly.

More recent history of the property includes a 2013 complaint about mold issues within the building. The rear yard area has been the subject of proposed changes, with planning records indicating consideration for merging two units into one and adding a parking space, though it's unclear from the records whether this was implemented. The property has experienced recurring issues with street signs being defaced, with multiple 311 calls between 2021-2023, and there have been several parking-related enforcement actions in the vicinity, though these are not directly related to the building's condition or management. The most recent building-related service calls have primarily concerned sidewalk cleaning and maintenance issues outside the building, suggesting regular attention to exterior upkeep.

Risk rating

How 1021-1023 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
