Initial analysis

The 9-unit, three-story multi-family residential building at 351 Cornwall Street in the Inner Richmond was built in 1904 and is currently owned by Richard Pung Lum Lee & Kit. The property has undergone several significant maintenance and upgrade projects in recent years, with the most substantial work occurring in 2021 when plumbing improvements were made including the replacement of cast iron pipes, nine water heaters, and kitchen pipe repairs. A notable fire safety incident occurred in March 2024 involving the fire escape, though this was resolved by May 2024. The building had a similar fire safety violation in 2022 regarding fire extinguishers, which was issued and subsequently abated. Historical violations from 2003 related to fire escape maintenance and smoke detector requirements were also addressed within a few weeks.

The property management has generally maintained the building's infrastructure, as evidenced by the 2021 plumbing updates and previous reroofing work in 1995. However, there has been a recent pattern of issues outside the building, with numerous 311 calls in 2024 primarily related to parking enforcement and some street maintenance concerns. These external issues included multiple reports of blocked driveways, curb defects, and occasional street cleaning needs. A tenant buyout occurred in March 2024 for one tenant at the nearby address of 204 5th Avenue for $60,000. The building's documented history shows regular inspections and prompt attention to violations, though the fire safety system has required periodic attention.

Risk rating

How 351 Cornwall 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
2th percentile

Out of 1723 buildings in this neighborhood, 1689 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.

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 24.3%
Moderate concern 47.4%
Severe concern 28.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
