409 42nd Ave, San Francisco, CA 94121

The two-unit residential building at 409 42nd Avenue in San Francisco's Outer Richmond district, owned by John Peter Nohrnberg Revoc Trust, has undergone several significant renovations since its construction in 1948. Most recently, in July 2023, the property received substantial upgrades including a kitchen and bathroom remodel, addition of washer/dryer facilities, complete rewiring of knob and tube electrical systems, installation of a new sub-panel, and window replacement, with a reported cost of $45,000.

This project was accompanied by corresponding plumbing and electrical permits. In 2008-2009, the building underwent another major renovation involving kitchen and bathroom modifications, including the conversion of a shower into a laundry area, installation of new appliances, and electrical upgrades, costing approximately $20,000.

Earlier maintenance work included rear stair repairs in 2007 (following a complaint about unpermitted work), reroofing projects in 1990 and 1997, and various sidewalk maintenance issues documented between 2014-2016, including reports of collapsed sidewalks and loose garbage that were subsequently resolved. The property has maintained compliance with permit requirements, though there was one complaint in 2007 regarding unpermitted stair repairs that was eventually addressed.
