645-647 Natoma St, San Francisco, CA 94103

The three-unit multi-family residential building at 645-647 Natoma Street, owned by Iyer Shekhar, was constructed in 1908 and stands three stories tall in San Francisco's South of Market neighborhood. The property has undergone several significant maintenance and improvement projects over the past two decades, with the most recent work focusing on water heater replacements in 2023, 2021, and 2019, indicating regular maintenance of essential systems. Other recent improvements include the construction of a home office space with pocket doors in 2019 ($10,000 project), and earlier structural work in 2005 involving the replacement of basement piers and posts ($3,000 project).

The building's history reveals some concerning events from the 1990s, including multiple tenant complaints about maintenance issues, with reports of foundation problems, structural concerns, and various plumbing and electrical issues. A notable incident occurred in 2000 when all front windows were boarded up following a fire. However, there have been no major housing code violations or serious safety incidents reported in recent years.

The property has undergone regular housing inspections, including a health and safety inspection in 2010, and appears to have resolved all identified issues. In recent times, there have been recurring issues with street cleanliness and garbage management in the vicinity of the property, as evidenced by multiple 311 calls in 2024 regarding garbage and debris, though these appear to be external to the building itself. The building's permit history shows ongoing investment in maintenance and upgrades, with particular attention to plumbing systems as evidenced by the multiple water heater installations. The most recent permit activity and inspection records suggest that the current ownership has been maintaining the property and addressing infrastructure needs, though historical records indicate there were significant maintenance challenges in the 1990s that required attention.
