Initial analysis

The three-story, three-unit multi-family residential building at 288 Union Street in Telegraph Hill, owned by Wilsey Gopp LLC, has undergone significant renovations and faced several regulatory challenges over its history, particularly in recent years. Most notably, the property completed the conversion of its first-floor area into an ADU (Accessory Dwelling Unit) in 2021, along with comprehensive unit upgrades in 2018-2019 that included kitchen and bathroom remodels, electrical system upgrades, and plumbing improvements across multiple apartments. However, there were multiple building complaints in 2019 regarding unpermitted work, including concerns about dangerous construction practices, plumbing work, electrical work, and unauthorized changes of use. These issues were subsequently addressed through proper permitting processes, though there remains an active complaint from April 2020 regarding roof deck construction and associated plumbing work.

The building has a documented history of maintenance and upgrades dating back to 1986, including structural work, window installations, and various apartment refurbishments. In 2010-2012, the property faced violations related to lead paint hazards, which were resolved through appropriate remediation work. Recent activity includes a proposed roof deck and railing replacement (filed July 2024) and the installation of new outdoor lighting that generated complaints in 2020 regarding brightness and motion sensitivity. The property has experienced periodic plumbing issues, with documented water leaks in 2015-2016, and has undergone various electrical and plumbing improvements over the years, including a ground floor washer/dryer installation in 2011 and comprehensive unit upgrades in 2019. A notable pattern of maintenance and upgrading work is evidenced by the multiple permits and improvements made throughout the building's history, demonstrating ongoing investment in the property's upkeep and modernization.

Risk rating

How 288 Union 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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
25thpercentile

Out of 684 buildings in this neighborhood, 513 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
