533 Diamond St, San Francisco, CA 94114

The three-story, two-unit multi-family residential building at 533 Diamond Street in Noe Valley, owned by William Hellendale, was constructed in 1912 and has undergone several significant renovations and encountered multiple compliance issues over the years. Most notably, the property experienced recurring problems with unpermitted work and illegal unit conversions between 2008 and 2015, including unauthorized kitchen installations in the basement and garage areas, which resulted in multiple violations and fines.

In 2017, the building faced ongoing issues with a chimney installation that allegedly violated clearance requirements, creating smoke problems for neighboring properties. More recent records indicate a series of maintenance and compliance matters, including construction materials blocking the sidewalk (August 2024) and multiple instances of illegal parking on the sidewalk (May and June 2024). The building's renovation history includes several substantial improvements, such as the installation of dual solar PV systems for both units in 2009, a 200-amp electrical service upgrade in 2008, and various plumbing upgrades including new water heaters and bathroom fixtures.

The property has also undergone multiple inspections and permit renewals to address dry rot repairs, window replacements, and porch modifications. While most recent complaints have centered around temporary parking and sidewalk issues, the building's extensive permit history suggests ongoing maintenance and improvement efforts by the owner. The property has been subject to regular inspections and final inspections for completed work, indicating a process of complying with building codes, though several permits and violations required renewal or extension in previous years.
