Initial analysis

The two-family residential building at 255 Henry Street in Corona Heights, owned by Donald F. Robertson, is a 2-story flats and duplex structure built in 1909. The property has undergone several significant modifications over the years, with the most substantial work occurring in 2006 when a comprehensive renovation was completed that included roof reframing, re-roofing, skylight installation, interior stair construction, and the addition of a powder room for $25,000. An electrical upgrade in 2004 installed a new 200-amp service with two meters, and in 2007, solar power was added to a storage shed. However, the property has a notable history of housing-related violations and complaints, particularly regarding an illegal in-law unit in the backyard shed. Between 2010 and 2013, multiple complaints were filed about unauthorized occupancy of the shed, lacking essential utilities, which were eventually resolved by September 2017 when a series of violations related to building, electrical, and plumbing permits were abated. A more recent complaint in February 2023 raised concerns about unsafe hand railings on back steps.

The building's permit history shows some attempted improvements to the rear garden structure, including a proposed roof raise in 2006, though this permit was withdrawn. Planning records indicate various proposals for the property, including plans to enlarge an oversized accessory building and replace an existing exit stair with code-compliant features, though not all these proposals were carried through to completion. The property has experienced several routine maintenance issues and external matters documented through 311 calls, primarily related to street cleaning, parking enforcement, and tree maintenance, with multiple reports of abandoned vehicles in the vicinity between 2010 and 2012. These external issues were generally resolved promptly by city services.

Risk rating

How 255 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.
