Initial analysis

The 6-unit, 3-story multi-family residential building at 1850 Larkin Street in Nob Hill, owned by Pun Fmly Tr, was constructed in 1913 and has undergone several significant safety upgrades in recent years. Most notably, in late 2023, the building completed a comprehensive fire alarm system upgrade to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas and updating existing devices for improved compatibility. This $30,000+ project was preceded by a related modification in January 2024, indicating ongoing commitment to resident safety. The building's electrical systems have also seen substantial improvements, including a 225-amp service upgrade in 2009 and extensive emergency lighting installations in 2003. Historical records show attention to building maintenance, with a 2010 permit for boiler disconnection and compliance work completed in 1985.

Recent 311 calls between 2021 and 2024 indicate ongoing maintenance concerns in the vicinity of the building, including reports of garbage, debris, and overflowing city garbage cans, though these are primarily street-related issues rather than building-specific problems. There were three notable building inspection cases between 1999 and 2008, including a 2003 complaint about a malfunctioning smoke detector and an illegal unit in the garage, both of which were resolved. While there have been two instances of graffiti reported on the building in 2022 and 2023, these were addressed, though some delays were noted due to pandemic-related enforcement changes. The most recent building permits and 311 calls suggest active management of the property, with particular focus on maintaining safety systems and addressing exterior maintenance issues.

Risk rating

How 1850 Larkin 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
61th percentile

Out of 1125 buildings in this neighborhood, 439 are predicted to be safer.

Model explanation

What's driving this score

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast

Moderate concern 23.8%
Severe concern 26.3%
