3572-3576 18th St, San Francisco, CA 94110

The 6-unit, 3-story multi-family residential building at 3572-3576 18th Street in Mission Dolores, owned by Buitrago Family Trust 2/28, has undergone significant improvements since its construction in 1905. Most notably, the property completed critical seismic improvements with a mandatory soft-story retrofit in 2017, valued at $65,000, which included the installation of Simpson Strong Walls and wood shear walls, bringing the building into compliance with San Francisco's seismic requirements. Subsequent upgrades included a comprehensive window replacement project in 2019 costing $26,000, which installed Weather Shield aluminum-clad wood double-hung windows across the front facade. The building's history shows attention to safety and compliance, particularly regarding seismic upgrades.

However, there have been recurring issues with unit configuration and unauthorized modifications. In 2003, an inspection revealed unauthorized use of ground floor "family rooms" as sleeping quarters, resulting in violations that were eventually abated by November 2003. Earlier in the same year, there were complaints about unauthorized work in the front stairwell. Various inspection records from 1997 through 2003 documented concerns about potential illegal units in storage areas, while subsequent routine inspections between 1997 and 2010 showed "no violations found" status.

The property has also maintained active compliance with street space regulations, obtaining necessary permits throughout the years. Recent activity primarily consists of maintenance and external issues, with 311 calls from 2023-2025 primarily related to parking enforcement and graffiti on or near the property. The building's soft-story retrofit status is marked as "Work Complete, CFC Issued," indicating successful completion of this critical structural improvement. The property has shown consistent progress towards compliance with building codes and safety requirements, particularly regarding seismic considerations, though historical records suggest periodic challenges with unauthorized unit usage and modifications.
