40-42 Tioga Ave, San Francisco, CA 94134

The two-unit residential building at 40-42 Tioga Avenue in Visitacion Valley, owned by Eric Hom and Irene Wong, has a documented history of both maintenance and significant repair issues. Most recently, in August 2024, a substantial reroofing project was completed at a cost of $15,000 using synthetic underlayment and shingles.

The building has undergone several window replacement projects, including installations in 2014 and 2018 that focused on energy efficiency improvements with proper U-factors, though they have now been superceded by the recent 2024 window replacement permit that indicates compliance with current building standards. The property experienced notable maintenance challenges in 2013, including serious water damage and mold issues that affected both units, with complaints filed about ceiling holes, wall damage, and the use of unlicensed repair personnel, all of which required official citations and permits for remediation. Earlier records from the late 1990s show various safety concerns, including electrical wiring issues and problems with a rotting deck, though these were resolved at the time.

More recently, there have been repeated sewage backup issues from the side sewer vent, with incidents reported in October and November 2024. The building's maintenance history shows regular attention to structural and safety issues, with repairs for termite damage in 2002 and building code violations addressed promptly when cited. While many past violations and repair issues have been resolved through proper channels, the recent sewer backup problems suggest ongoing infrastructure challenges.
