Initial analysis

The three-unit residential building at 12-14 Henry Street in Duboce Triangle, owned by Alfred D & Moyra P Trigueir, is a three-story flats and duplex structure built in 1913. The property has undergone several significant improvements over the past two decades, with the most recent major work being the 2016 addition of a bathroom facility to the ground floor common area, which included associated plumbing and electrical work costing $15,000. Prior improvements in 2004 included substantial updates to both units, comprising kitchen and bathroom remodels ($23,000), electrical system upgrades ($40,000 for comprehensive wiring work), and roofing replacement ($14,200). The building has been subject to routine housing inspections in 2000 and 2010, both of which were resolved, and there are no active violation records on file.

Recent activity around the property has primarily involved external maintenance and neighborhood-related issues rather than building-specific concerns, with multiple 311 calls in 2020-2021 regarding illegal postings and tree maintenance. The most recent planning record indicates completed interior alterations at the basement level, including a new half-bath, though this appears to be part of the earlier completed work from 2016. The building's maintenance history suggests regular upkeep and modernization efforts by the owners, with no significant pattern of complaints or violations that would impact resident safety or comfort.

Risk rating

How 12-14 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.
