1271 23rd Ave, San Francisco, CA 94122

The two-unit residential building at 1271 23rd Avenue in the Central Sunset neighborhood is a two-story flats and duplex structure built in 1926, currently owned by Kuang Shi Hao. The property has undergone several significant improvements in recent years, including a $15,000 reroofing project scheduled for 2024, replacement of eleven front facade windows with period-appropriate wood-framed casements in 2019, and a comprehensive bathroom remodel in 2019 that addressed multiple code compliance issues including plumbing, electrical, and fire safety violations.

Notably, the building faced several building violations in 2019 related to windows, electrical systems, and safety equipment, all of which were successfully abated by September 2021. These violations were initially triggered by complaints regarding unpermitted bathroom and window work in Unit #1273, along with issues of mold, water pressure, and inadequate heating systems. The property has experienced several infrastructure challenges in recent years, including sewage backup issues in August 2023, and ongoing concerns about tree roots lifting the sidewalk, as documented in multiple 311 calls in 2024.

Recent maintenance activities include sidewalk repairs and responses to parking violations near the property. Historical records show earlier repairs from 1986 related to back door framing issues and a plumbing system upgrade in 1991 for terra-cotta pipe removal. The building's recent history indicates active management of both routine maintenance and compliance with building codes, though the property has experienced recurring issues with tree root damage to the sidewalk and periodic parking enforcement matters.
