Initial analysis

1340 Vallejo Street is a three-story, six-unit multi-family residential building constructed in 1911 and located in San Francisco's Russian Hill neighborhood. The building has a significant history of fire safety upgrades and incidents, most notably experiencing fire damage in 1990 that required substantial repairs and led to the installation of a fire sprinkler system in the basement. In recent years, there have been proactive efforts to enhance fire safety systems, including a 2023 permit to replace the fire alarm system and install low-frequency horns, following an earlier (and subsequently cancelled) permit in 2021 for a more comprehensive fire alarm upgrade. The building underwent routine housing inspections in 2001 and 2008, with the 2008 inspection identifying multiple fire safety-related violations that were resolved within one month, including issues with fire alarm recharge and electrical systems.

The property's maintenance record shows attention to various infrastructure needs, including a furnace replacement in 2010. Recent external issues include a 2024 sidewalk defect that was resolved, and past incidents such as construction noise complaints and waste management concerns in the vicinity. The building's location has been subject to typical urban challenges noted in 311 calls, such as sidewalk cleaning and parking issues, which have all been resolved. Historical records show the building was reconstructed following the 1990 fire incident, with multiple planning records indicating the involvement of various developers in the rebuilding process within the RH-3 zoning district.

Risk rating

How 1340 Vallejo 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 1133 buildings in this neighborhood, 544 are predicted to be safer.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
