735-737 20th Ave, San Francisco, CA 94121

The 735-737 20th Avenue property is a 2-unit, 2-story multi-family residential building located in the Central Richmond neighborhood, built in 1922 and currently owned by Yang Hung Lin & Cheng Yanki. The building has undergone significant renovations over the past decade, with substantial work occurring between 2016-2017. The improvements included comprehensive remodeling of both units' kitchens and bathrooms, with unit 737 receiving a new master bath, and unit 735 receiving bathroom and kitchen upgrades.

Structural enhancements included garage beam and post modifications, including the replacement of wood posts with steel columns, and the installation of garage wall anchor bolts and plywood. Systems upgrades comprised of new electrical panels, lighting, plumbing fixtures, and HVAC improvements, including the relocation of a furnace and installation of a new wall-mounted water heater. The property's history includes one significant code violation in 1999 regarding an illegal unit behind the garage with unauthorized electrical and plumbing work, though this was resolved within four months.

The building has been subject to multiple parking-related issues in recent years, with three driveway blocking incidents reported between January and August 2023, though these are not uncommon in urban areas. Street cleaning matters related to Christmas tree disposal were reported in early 2022, and there were two abandoned vehicle complaints (in 2018 and 2011) near the property, but in each case, the vehicles were gone when authorities arrived. The property underwent several structural and system improvements in the late 1980s, including brick veneer repair and other maintenance work. A recent planning record from 2022 indicates a proposal to connect rooms down to the lower flat and convert them into a bedroom, media room, exercise space, and full bath, with an Affidavit of No Unauthorized Unit on File, though it's unclear from the records if this was completed.
