2833-2835 Union St, San Francisco, CA 94123

The property at 2833-2835 Union Street is a four-story, two-unit multi-family residential building constructed in 1933, currently owned by Last Block LLC. The building underwent significant renovations in 2013-2015, including the addition of a fourth-floor penthouse and decks, reconfiguration of front stairs and garage, comprehensive interior remodeling of both units, and major system upgrades (electrical, mechanical, and plumbing) with a reported cost of $500,000.

During this renovation period, several safety improvements were made, including the installation of a fire sprinkler system with 76 heads ($20,000) and replacement of cracked terracotta flue tiles with a metal flue system ($12,884). The building has had some operational challenges, particularly in 2015 with violations related to boiler permits, which were resolved by June 2015. A complaint regarding window replacements in 2016 was filed concerning alleged intrusion into neighboring property, though this was noted as "not active." More recent issues include 311 calls for a blocked sidewalk due to construction materials in 2015, rodent/insect infestation in early 2015, and a sewage backup incident in 2014.

The property has maintained compliance with building codes, as evidenced by the successful completion of multiple permits and inspections, though there have been some instances of permit-related penalties that were ultimately resolved. The building's recent history shows substantial investment in modernization and safety upgrades, though this was accompanied by some temporary disruption and operational issues typical of significant renovation projects. The property underwent mandatory design review for unit merger and received CEQA clearance, indicating adherence to regulatory requirements during the renovation process.
