Initial analysis

The 6-unit, 3-story multi-family residential building at 1849 Larkin Street in Nob Hill, owned by Thomas Ong and Betty Ong Szet, has undergone several significant improvements since its construction in 1910. Most recently, in July 2023, the building received an upgrade to its fire alarm system to comply with San Francisco Fire Code requirements, following a similar electrical modification completed in April 2023 that included installing low-frequency sounders in sleeping areas for enhanced safety. The building has also addressed important structural concerns, completing mandatory seismic soft-story upgrades in 2016, and obtaining a Certificate of Final Completion (CFC). Other notable improvements include a reroofing project in 2018 and substantial interior improvements to a retail space in 2014, which included comprehensive electrical and plumbing work, though some of these permits ultimately expired.

The building's maintenance and safety record shows regular attention to necessary updates, particularly regarding safety systems. While there have been two routine housing inspections (in 1999 and 2003), no significant violations or concerns were noted. A recent cluster of 311 calls from August to December 2024 primarily related to parking enforcement issues and sidewalk cleanliness matters outside the building, as well as some garbage and debris complaints, though these appear to be more related to street-level conditions rather than directly indicating problems with the building itself. The property has maintained compliance with fire safety requirements, with no merit found in a 2014 fire alarm system complaint, marking it as a building that has proactively addressed both safety and structural requirements, particularly focusing on modernizing its fire safety systems and complying with seismic retrofit mandates.

Risk rating

How 1849 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

Out of 1125 buildings in this neighborhood, 518 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

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

Neighborhood (ZIP code)

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

12-Month severity forecast
No violation 42.8%
Moderate concern 48.7%
Severe concern 8.6%
