842-844 33rd Ave, San Francisco, CA 94121

The 842-844 33rd Avenue property is a two-unit, two-story multi-family residential building located in San Francisco's Outer Richmond neighborhood. Built in 1924 and currently owned by the Gee Marital Trust, this flats/duplex structure has undergone several significant modifications and improvements over the past decade. The most notable recent development was the comprehensive installation of a new fire sprinkler system in 2016-2017, which required multiple permits and associated costs totaling over $25,000.

This project was completed in response to a notice of violation related to an illegal in-law unit at the ground floor rear of the garage area, which was subsequently legalized through a $55,000 permit in 2015. The building has also undergone substantial interior renovations, including kitchen and bathroom updates in both units (2014), window replacements (2014, with some permit compliance issues), and additional safety features such as a sprinkler monitor system (2017). The property has a documented history of code compliance challenges, particularly in 2014 when multiple violations were filed regarding unauthorized unit modifications, including work done without proper permits following a fire incident.

These violations, which carried monthly monitoring fees, were ultimately abated in 2017. The building's maintenance record shows attention to basic infrastructure, including a roof replacement (2019) and various plumbing and electrical upgrades. Recent external maintenance issues documented through 311 calls have primarily involved sewer problems, with the most recent being a flooding incident in December 2021. The property's compliance history suggests a significant effort to address past violations and improve safety systems, though potential concerns over some permit compliance during 2014 renovations should be noted.
