1477-1479 Guerrero St, San Francisco, CA 94110

The two-unit residential building at 1477-1479 Guerrero Street in Bernal Heights, owned by Guerrero Property LLC, is a two-story flats and duplex structure built in 1900. The property has undergone significant recent activity focused on structural improvements and unit renovations. Most notably, from 2023-2024, there have been multiple permits related to voluntary structural strengthening and seismic improvements, including revisions to remove two shear walls from previously planned voluntary structural strengthening work.

These structural modifications began with a $40,000 project in May 2023, with subsequent revisions to reduce the scope. The building underwent substantial unit improvements in 2020, including kitchen and bathroom remodels totaling $80,000 in both units, with completed plumbing and electrical upgrades, though some permits initially expired requiring renewal for final inspection in late 2023. Historically, the building faced maintenance issues that were addressed between 2006-2007, including problems with interior surfaces, lead paint concerns, security requirements, and fire safety issues, all of which were officially abated.

A notable tenant complaint from 2006 reported electrical system problems, inadequate hot water, and other maintenance concerns, but these issues appear to have been resolved. The property has undergone significant recent work, particularly in the context of seismic safety improvements, and has maintained active responses to building code requirements. Recent 311 calls primarily relate to street-level issues such as garbage, graffiti, and parking concerns, which are separate from building-specific matters. A tenant buyout occurred in November 2019 involving two tenants for $130,000, though this appears to have been outside the current permit and improvement timeline.
