Initial analysis

The two-unit residential building at 547-549 42nd Avenue in San Francisco's Outer Richmond district is a two-story flats and duplex structure built in 1947, currently owned by the Joseph A Wrigley 2005 Revocable Trust. The property's most significant renovation occurred in 2005-2006, when a $50,000 project was initiated to convert the first floor area into habitable space, including window replacements, kitchen and bathroom remodels, and the addition of a new bay window at the rear. This work required multiple permits across building, electrical, and plumbing trades, with some permits expiring and needing renewals, though the electrical work received final inspection completion in February 2007. Earlier building maintenance included stucco repairs and addressing dry rot damage in 2006, for which $3,000 was spent, and more remote issues were addressed in 1990 with the addition of foundation bolts.

The property has experienced several municipal service calls over the years, though none indicating severe safety concerns. These include three sidewalk-related complaints between 2016 and 2017, with inspections finding only minor cracks that did not constitute hazardous conditions. Other incidents included a resolved illegal posting in 2014 and one instance of offensive graffiti on a pole in 2010. A human or animal waste issue was reported in 2019, which was subsequently resolved. The building's documented history shows regular maintenance and improvement efforts, with most significant work occurring between 2005-2007, while more recent records indicate generally routine urban maintenance matters rather than building-specific issues.

Risk rating

How 547-549 42Nd Ave'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.
