811 Carolina St, San Francisco, CA 94107

This two-unit, two-story multi-family residential building located at 811 Carolina St in Potrero Hill was constructed in 1911 and currently owned by 811 Carolina LLC. The property has undergone significant renovations and improvements over the past several years, including substantial work in 2018-2020 featuring a first-story horizontal addition, kitchen reconfigurations, and the installation of comprehensive fire safety systems with new sprinklers throughout the building and a monitoring system.

Major infrastructure upgrades occurred in 2019-2020, including a rooftop heat pump installation, new plumbing systems including PEX, and electrical improvements including a rooftop PV solar system. The building had several historical violations and complaints in the 2007-2009 period, including issues with heating systems, handrails, and plumbing concerns, though all these violations were ultimately abated by March 2009.

A recent resolution regarding potential unauthorized short-term rentals was addressed, with compliance confirmed after tenant and ownership cooperation. Recent maintenance issues have primarily been related to exterior features such as tree maintenance and street cleaning, with no serious violations or complaints recorded in recent years. The most recent building improvements indicate a focus on sustainability and modern amenities, including solar power and updated fire safety systems, while recent 311 calls primarily concern general maintenance issues in the surrounding area rather than building-specific problems.
