1241 18th Ave, San Francisco, CA 94122

Situated in San Francisco's Inner Sunset neighborhood, 1241 18th Avenue is a two-story, five-unit multi-family residential building constructed in 1924 and currently owned by Lam Tran. The property has undergone several significant structural improvements, most notably completing a mandatory soft-story seismic retrofit in 2016 that included the installation of steel moment frames, plywood shear walls, and fireproofing, demonstrating compliance with San Francisco's earthquake preparedness requirements. The building's maintenance history shows attention to fundamental safety systems, including sprinkler installation in 1986 and various plumbing and electrical upgrades, though there were notable maintenance challenges in 2017 when multiple housing violations were recorded in May related to fire safety, sanitation, plumbing, electrical systems, and interior surfaces.

These violations were subsequently resolved by May 2018, though one particular complaint regarding sewage backup persisted through May 2017, with reports suggesting ownership reluctance to address issues prior to a sale. The building's recent maintenance record shows ongoing attention to structural and safety needs, including plumbing improvements in 2016, though an expired permit from 2000 regarding stucco repairs on front bays remains on record. Regular routine inspections have been conducted through the years, with historical records showing various maintenance needs being addressed over time.

The property has experienced recurring parking-related issues outside the building, as evidenced by multiple parking enforcement calls between 2018 and 2024, along with occasional reports of debris and sidewalk blockage. While the building's major systems have received necessary upgrades and safety improvements over the years, the concentration of violations and repair requests in 2017 suggests there was a period when maintenance could have been more timely addressed, though this appears to have improved in subsequent years. The most recent soft-story retrofit completion indicates substantial investment in building safety and structural integrity.
