Initial analysis

The 7-unit multi-family residential building at 1525 Larkin Street in Nob Hill, owned by Steven T Ching Tr, has undergone several significant infrastructure upgrades since its construction in 1973. Most recently, in 2023, the building had major boiler system work completed, including the removal of an old boiler, installation of a new boiler, and hot water tank system updates. The building has also seen important safety improvements, with a comprehensive fire alarm system upgrade completed in 2020-2021 that included new control units, smoke detectors, and low-frequency sounders throughout the property to meet current safety standards. Other notable improvements include window replacements (2013), rear wall stucco repairs (2013), and a complete reroofing project (2005), demonstrating regular maintenance and updates to building systems.

The property has experienced some compliance challenges, most notably in 2023 when multiple violations were recorded regarding boiler permit requirements, though these violations were ultimately abated by May 2023. There appears to be an ongoing boiler permit compliance issue as of July 2024, which is currently listed as active. The building's maintenance record shows regular responses to infrastructure needs, such as bathroom updates and laundry facility improvements. External to the building itself, there have been several reported incidents requiring municipal response, including graffiti removal (2023), sidewalk cleaning (2024), and occasional sewage system issues (2023), though many of these cases have been resolved promptly and do not seem to indicate persistent problems. The property has undergone routine housing inspections in 2000 and 2008, both of which were resolved.

Risk rating

How 1525 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
27th percentile

Out of 1125 buildings in this neighborhood, 821 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 location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 29.8%
Moderate concern 50.4%
Severe concern 19.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
