Initial analysis

The 6-unit, 3-story apartment building at 3460-3464 18th Street in the Inner Mission, owned by Guerrero V Espinoza Trust, has a complex maintenance and compliance history since its construction in 1908. Most concerning is the building's current non-compliant status with the Mandatory Soft Story Retrofit Program (Tier 4), with an active violation filed in December 2022 regarding failure to complete required work and obtain final signoff, with a director hearing scheduled for June 26, 2024. The owner had previously initiated a soft story retrofit in 2017 with a permitted cost of $60,000, which remains incomplete despite a subsequent permit renewal in 2019. The building has experienced several significant maintenance issues over its history, including a fire-related renovation in 1993 that affected multiple areas including kitchen and bathroom, and historically concerning safety violations such as a blocked exit in 2008 (which was subsequently corrected) and a period of rodent infestation that same year. More recent maintenance records show recurring issues with sidewalk cleanliness, as evidenced by multiple 311 calls for graffiti and debris in late 2024, though most of these were resolved through normal city services. The building's Age/Type designation as a 5 to 14 unit Apartment structure suggests standard multi-family residential characteristics, and while there have been routine inspections by the Department of Building Inspection (DBI), the most pressing current issue is the unresolved soft story retrofit compliance, which has been under discussion since at least 2018.

Risk rating

How 3460-3464 18Th 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

Out of 2380 buildings in this neighborhood, 1999 are predicted to be safer.
