347-349 10th St, San Francisco, CA 94103

The property at 347-349 10th Street in San Francisco's South of Market neighborhood is a two-story, Class A historic resource multi-family residential building constructed in 1908, currently owned by Liang Xianhui. The building is undergoing significant proposed changes, with approved permits from December 2022 for a substantial renovation project valued at $1.8 million that includes a 14-foot horizontal addition, vertical extension to add a new 5-bedroom townhouse unit, seismic upgrades, fire sprinklers installation, and egress improvements. This follows earlier permits filed in June 2019 proposing to demolish the existing duplex and replace it with a 5-story multi-family dwelling, though these permits were later withdrawn in favor of the current approved plans.

The building has a mixed maintenance and violation history, with notable events including multiple unauthorized short-term rental violations that were eventually abated, and various maintenance and improvement projects over the years. These include plumbing repairs completed in 2008, electrical upgrades in 2005, and basement modifications for exercise space in 2005. Recent 311 calls from 2024 have primarily related to street-level issues such as garbage, debris, and graffiti, though most of these were resolved without requiring significant action.

A notable historical aspect of the building's recent past is a July 2019 fire complaint that was determined to have no merit, and there are no recorded tenant buyouts associated with this address. The proposed renovation project represents a major upgrade to the building's infrastructure and living conditions, addressing modern safety requirements while expanding the usable space. The building's location in a historic district means that any modifications are subject to preservation standards, with particular attention being paid to the proposed 10-foot setback from the facade and the configuration of new bedrooms and bathrooms.
