Initial analysis

The property at 1432-1434 Jefferson Street is a two-unit, two-story multi-family residential building located in the Marina neighborhood, constructed in 1932 and currently owned by Armstrong Marina. The building has undergone several significant renovations over the years, with the most notable occurring in the early 2000s when extensive bathroom and kitchen remodels were performed across both units, including electrical upgrades and the installation of new fixtures. A major compliance issue arose in 2007 regarding unauthorized modifications to a ground floor space behind the garage, which had been converted into a residence with a full bathroom and shower, bedroom, and wet bar, contrary to its permitted use as a home office/study, storage room, and laundry with half bath. This violation was not fully resolved until September 2013, despite multiple Notices of Violation (NOVs) issued between March 2007 and February 2013. The building has seen regular maintenance and updates, including window replacements in 2007, reroofing in 2001, and more recent improvements such as a furnace replacement in 2019 and the installation of a Tesla charging station in 2016.

The property is currently up to code with no active building violations, though there have been several maintenance issues documented through 311 calls in recent years, primarily relating to sidewalk defects and parking violations. The most recent building-related activity was a hazardous materials report regarding glass on the property that was resolved in December 2023. Planning records indicate an approved top story horizontal addition and roof deck modifications, though these records should be verified for current status. The building's maintenance history demonstrates regular upkeep and modernization efforts by the owner, though the previous compliance issues regarding unauthorized unit modifications highlight the importance of adhering to permitted use requirements.

Risk rating

How 1432-1434 Jefferson 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.
