Initial analysis

The property at 134 28th Street is a two-story, four-unit multi-family residential building located in Noe Valley, owned by the Lee/Wong Marital Trust and constructed in 1950. The building has undergone significant improvements and maintenance over the past decade, with the most recent major work occurring in 2019-2020, including siding replacement, window upgrades, and dry rot repairs. Between 2013 and 2014, all four units received substantial renovations, including kitchen and bathroom remodels, electrical upgrades, and new appliances, with a complete rewiring of Units 1, 2, and 3 including new subpanels and circuits. The building's systems have been regularly updated, including a 200-amp electrical service upgrade in 2011 and multiple heating system replacements.

The property has a history of addressing maintenance and safety requirements, though there were several building violations noted in 2000-2001 related to safety equipment (fire extinguishers, gas shutoff tools, smoke detectors) that were subsequently resolved. A more recent complaint in 2019 regarding unauthorized siding removal was investigated but ultimately resolved. The building underwent a routine inspection in 2008, and while there have been various 311 calls regarding the surrounding area (primarily street-related issues), these are not directly related to the building's condition or management. The property has maintained active compliance with building regulations since its most recent renovation period, with no active violations or complaints on record as of October 2023.

Risk rating

How 134 28Th 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.
