Initial analysis

The two-unit residential building at 129 Henry Street in the Duboce Triangle, owned by John D Moriarty 2012 Revocable Trust, is a two-story flats and duplex structure built in 1902. The property's history reveals several significant maintenance and infrastructure issues, particularly in 2021 when there were documented sewer problems including a sewage backup and a water leak involving the house-to-property connection, for which the property owner was deemed responsible for repairs. The building has undergone various permits and modifications over the years, including a completed horizontal addition in 1997 and multiple sidewalk permits, though some earlier permits from the 1980s have expired.

Recent incidents near the property between 2020 and 2025 highlight ongoing maintenance and environmental challenges in the vicinity. These include multiple instances of parking violations on the sidewalk, graffiti, and reports of garbage and debris on public property. The building had two combustible materials fire complaints in October 2012, which were resolved by March 2015, though there was also a hazardous condition incident recorded with no civilian injuries. Additionally, there have been several tree-related concerns reported between 2020 and 2022, including one case where a tree was reported to be damaging property, though an arborist inspection determined it was clear of the building. The most recent work on record was a sidewalk permit issued in 2008, suggesting limited recent external modifications to the property.

Risk rating

How 129 Henry 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
13th percentile

Out of 287 buildings in this neighborhood, 250 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.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

12-Month severity forecast
No violation 38.7%
Moderate concern 45.4%
Severe concern 15.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
