Initial analysis

The property at 16-18 John Street in Nob Hill is a two-unit, two-story multi-family residential building constructed in 1919, currently owned by the Ying Wong Revocable Trust. The building's history reveals significant modifications and compliance issues, most notably in 2008 when violations were documented regarding ground floor rooms occupied as habitable space without proper permits. This led to a compliance order and subsequent renovation work costing $18,000 to remove an illegal kitchen and legalize bathroom and storage spaces, along with adding a laundry room. These improvements were accompanied by corresponding plumbing and electrical upgrades, including the installation of lights, switches, receptacles, and the electrical service conversion with a 150-amp main service upgrade completed in 2003.

The building's maintenance record indicates periodic attention to external issues, with several 311 calls between 2014 and 2020 relating to graffiti removal and general cleaning needs around the property. While there have been multiple reports concerning park structures and sidewalk maintenance in the vicinity, these were handled by appropriate city departments and were not directly related to the building's condition. The most recent documented issue was a graffiti incident on the residential portion of the building in January 2020, which was resolved. The property's documented history shows that most major compliance issues have been addressed, with no active building violations on record since 2008.

Risk rating

How 16-18 John 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
89th percentile

Out of 1125 buildings in this neighborhood, 124 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 age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

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 82.6%
Moderate concern 10.9%
Severe concern 6.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
