Initial analysis

The three-unit, three-story multi-family residential building at 1739-1743 Larkin Street in Nob Hill, owned by Frank Chiu, has undergone several significant renovations since 2017. The most substantial work occurred during 2017-2018, involving structural modifications including wall removals and beam installations on the third floor, along with steel column relocations across all floors. These structural changes were accompanied by comprehensive interior improvements, including electrical upgrades with installation of numerous fixtures and appliances, and plumbing work for bathroom remodels and a new furnace installation. A notable incident occurred in October 2018 when construction activities reportedly blocked the sidewalk and generated dust problems, though this complaint is now inactive.

Prior to these recent improvements, the building had undergone other maintenance work including a reroofing project in 1995 and window installations in 1985. The property has been subject to routine housing inspections in 2000 and 2008, both of which were resolved. More recent 311 calls from 2022 to 2024 have primarily concerned external issues such as sidewalk cleaning and pavement defects near the property, rather than building-specific concerns. While there are open cases regarding pavement defects from 2023, these relate to street conditions rather than building management. The most recent planning records indicate approved developments for ground floor rooms and third floor apartment renovations, showing ongoing investment in the property's maintenance and improvement.

Risk rating

How 1739-1743 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
91th percentile

Out of 1125 buildings in this neighborhood, 101 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.

Neighborhood (ZIP code)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 61.1%
Moderate concern 20.8%
Severe concern 18.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
