The property at 539-541 Waller Street is a 2-story, 3-unit multi-family residential building located in Hayes Valley, built in 1900 and currently owned by Joseph W. Mills. The building has undergone several significant improvements over the years, particularly in 2007 when substantial structural work was performed including voluntary beam reinforcement with additional posts ($5,000) and reroofing ($600).

Prior to this, in 2006, the property underwent various improvements including window replacements, kitchen renovations, and electrical work totaling approximately $4,000. The building has had two routine housing inspections (2002 and 2008) which identified several security and fire safety issues that were subsequently addressed, including fire extinguisher maintenance, security device repairs, and fire escape ladder maintenance. Two notable construction-related issues were reported in 2006 regarding unauthorized modifications - the addition of a driveway and garage - though these were resolved within a few months.

The property has experienced numerous maintenance and safety inspections since 2002, with the most recent incident being a smoke detector malfunction (date unspecified, no injuries reported). Recent activity at the property includes multiple 311 calls in 2024 primarily related to garbage and debris issues on the street and sidewalk, with one open maintenance issue regarding a pavement defect noted in September 2024. The building's most significant safety concerns have been addressed through various permits and inspections over the years, with no active violations currently on record. Historical inspection records show consistent attention to fire safety requirements, security improvements, and general upkeep, though there have been periodic issues with external debris management as evidenced by recent 311 calls.
