336 Hanover St, San Francisco, CA 94112

The property at 336 Hanover Street is a two-story multi-family residential building located in the Croker Amazon neighborhood, currently owned by Jiang Wen Feng. The building underwent significant changes between 2013 and 2016, including the legalization of an additional dwelling unit, with work encompassing the conversion of a laundry area to a kitchen, addition of a door, and installation of various electrical and plumbing fixtures. The legalization project, which cost approximately $100,000, included comprehensive updates to both units' electrical systems (with new lights, switches, and appliances) and plumbing infrastructure, including a 4-inch main sewer replacement.

More recent improvements include a roofing replacement project completed in 2024 and ongoing work to address compliance issues identified in a 2024 internal audit regarding front yard landscaping and safety requirements, including the installation of a fire-rated door and CO2 detector in the garage. The property has experienced recurring compliance and maintenance issues, most notably an active violation as of May 2024 concerning incomplete front yard landscaping and an expired plumbing permit. Historical records indicate an earlier violation regarding unauthorized unit construction in 2014, though this was subsequently addressed through proper permitting.

Recent months have seen multiple 311 calls regarding the property, primarily related to sidewalk parking violations and debris issues, with several parking enforcement actions resulting in citations. The building's infrastructure has received attention over the years, with documented improvements including window replacements, basement renovations, and updates to meet current building codes, though some work remains outstanding as per recent violation notices. The property has also been subject to fire safety inspections, with issues being addressed promptly when identified.
