620 Waller St, San Francisco, CA 94117

The two-story, two-unit multi-family residential building at 620 Waller Street in Hayes Valley, owned by Barber Living Trust, has undergone significant renovations and improvements in recent years. Most notably, in 2019, the building underwent a substantial interior remodel costing $114,000 that included window replacements (upgrading to double-pane windows) on the second floor, the addition of new skylights, and comprehensive updates to both kitchens and bathrooms including new gas lines, electrical circuits, fixtures, and appliances.

The electrical upgrade was particularly extensive, involving the installation of new circuits, outlets, fixtures, a sub panel, and various safety installations including smoke detectors. The property experienced heating system issues in January 2001, when a complaint was filed regarding inadequate heat provision during specified hours, though this violation was promptly resolved within a month.

More recent activity includes a permitted installation of a forced air central heating system in mid-2020, though the permit has expired. The building has generated multiple 311 calls in recent years, primarily related to parking issues (particularly driveway blockages) and street maintenance concerns, though these are not directly related to the building's condition or habitability. The property has also maintained compliance with planning requirements, as evidenced by approved window and skylight replacements that were confirmed to not violate any regulations.
