475-477 4th Ave, San Francisco, CA 94118

The four-unit, two-story multi-family residential building at 475-477 4th Avenue in the Inner Richmond district, owned by Emmanuel & Julie Pun since 2005, has undergone significant modernization and renovations since 2018. The most substantial project, completed in 2018, involved a $200,000 renovation of the front building, including foundation replacement, interior wall updates, kitchen and bathroom remodeling in both units, window replacements, and repairs to dry-rotted wood siding. That same year, the property underwent major infrastructure upgrades, including electrical system improvements with new panels and wiring, plumbing work including kitchen and bathroom remodeling, installation of on-demand water heaters, and replacement of underground sewer pipes.

The rear building saw the legalization of a first-floor dwelling unit in 2018-2019, with comprehensive updates to its systems including new electrical, plumbing, and HVAC installations. The building's maintenance record shows attention to structural integrity and resident comfort, with earlier renovations in 2009 addressing foundation issues, room layout changes, and bathroom and kitchen remodels. The property has experienced some infrastructure challenges, with two documented sewage backup incidents in 2019-2020, though the issues were addressed by PUC Sewer Operations.

Recent exterior maintenance included street space permits in 2018. The building's location has experienced recurring issues with sidewalk parking violations, with multiple enforcement actions taken between 2019-2022, though these are exterior matters unrelated to building conditions. A minor cooking-related fire incident occurred at some point, but with no civilian injuries reported. The property's comprehensive renovations and modernization efforts suggest a focus on maintaining and improving the building's infrastructure and resident amenities, though prospective tenants should be aware of the building's age (constructed in 1906) and the relatively recent history of sewer-related issues.
