Initial analysis

The two-unit residential building at 342-344 Duncan Street in Noe Valley, owned by John L Robinson & Pamela J, is a two-story flats and duplex structure built in 1900. The property has undergone significant structural and systems improvements over recent years, with the most notable recent work including a March 2023 installation of a new structural beam ($3,000) and comprehensive bathroom renovations in 2022-2023. Major historical work includes a substantial 2019-2020 project (costing $75,000) involving foundation replacement, floor leveling, and interior stair improvements, as well as earlier mechanical system upgrades including furnace and hydronic system replacement in 2016 ($16,222) and radiant heating work in 2017. The building's infrastructure has received consistent attention, with multiple plumbing permits related to heating and bathroom improvements, and electrical upgrades including lighting installations.

The property has maintained good structural integrity and modern systems, though there have been recurring utility-related adjustments, particularly regarding gas lines and heating systems, with the most recent work related to gas pipe relocation in April 2023. Some improvements proposed in 2015 for solar panel installation (2.6-3.8 kW) were cancelled, and there have been several street-related issues documented through 311 calls, primarily concerning parking enforcement and sidewalk access, though these are external to the building itself. The property underwent a significant ground floor transformation as part of the planning process, adding a full bath, bedroom, and interior stairs, which appears to have been successfully completed. While the building's maintenance record shows regular upkeep and modernization efforts, prospective tenants should note the extensive work performed over the past decade, totaling several hundred thousand dollars in improvements, reflecting ongoing investment in the property's infrastructure and systems.

Risk rating

How 342-344 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
99th percentile

Out of 1879 buildings in this neighborhood, 19 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.

Neighborhood location

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

Property class: single-family home

Single-family homes (class A) have distinct violation and complaint patterns from multi-family buildings.

12-Month severity forecast
No violation 89.7%
Moderate concern 7.8%
Severe concern 2.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
