Initial analysis

The two-story, multi-family residential building at 319 Duncan Street in Noe Valley, owned by Oneil Credit Shelter Trust, was constructed in 1964 and contains four units. The property has undergone several significant improvements over the years, with the most recent notable renovation being a comprehensive upgrade of Unit #4 in early 2022, which included kitchen and bathroom remodeling, electrical rewiring, plumbing updates, and the relocation of the electrical panel, with an investment of $50,000. Historical improvements include a complete reroofing in 1999 and the installation of a solar hot water system in 1983.

The building faced multiple safety-related violations in October 2002, including issues with smoke detectors and gas meter instructions, all of which were resolved by April 2003. A routine housing inspection was conducted in 2008 with no ongoing issues noted. Recent property maintenance and infrastructure concerns have been limited, with the most significant recent incident occurring in June 2012 involving a sewage backup that required attention to the 4-inch vent system and minor concrete repair work. Recent 311 calls from 2016 to 2024 have primarily related to external issues such as abandoned vehicles on the street, sidewalk cleaning needs, and a pavement defect, rather than internal building concerns. The property appears to be well-maintained, with no active violations or complaints on record in recent years, and the major systems have received regular maintenance and upgrades as evidenced by the permitting history.

Risk rating

How 319 Duncan 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
44th percentile

Out of 1879 buildings in this neighborhood, 1052 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.

Number of units

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

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 64.9%
Moderate concern 19.5%
Severe concern 15.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
