138-140 Corwin St, San Francisco, CA 94114

The property at 138-140 Corwin Street is a 4-story, 2-unit multi-family residential building constructed in 1981, currently owned by Henry Shao. The building has undergone significant improvements and maintenance over the past several years, with the most recent major renovation occurring in May 2023, involving comprehensive updates to lower unit bathrooms, windows, patio doors, wood floors, kitchen, and deck railings, along with the installation of a wet bar on the third floor at a cost of $325,000.

Prior to this, in 2022, the top floor unit received similar attention, including kitchen and bathroom remodeling, while structural maintenance work was performed in 2022 on the third-floor balcony joists and in 2014 on east-facing decks suffering from dry rot. Recent concerns have emerged regarding exterior lighting installed in 2023, with multiple complaints filed in 2024 about light trespass and glare affecting adjacent properties, with concerns about compliance with California lighting regulations.

The building's maintenance history shows regular upkeep, including the installation of a NFPA 13D fire sprinkler system in 1998, reroofing in 2014, and various plumbing and electrical upgrades, including a recent Cat5 residential network installation in November 2023. The property has experienced some issues in the past, including complaints about stairs, smoke detectors, and a sump pump in 1994, though these were resolved by 1997. Recent 311 calls indicate ongoing external maintenance needs, particularly regarding garbage and debris and an overgrown tree blocking the sidewalk, though many of these issues are typical for urban properties and appear to be actively managed.
