The three-unit, three-story multi-family residential building at 451-455 Guerrero Street in Mission Dolores, owned by Cora Shaw, has undergone significant renovations and improvements since 2020. Most notably, the property completed a voluntary soft-story retrofit in 2021 at a cost of $110,000, improving its seismic safety.

The building has seen comprehensive interior upgrades, including multiple kitchen and bathroom remodels between 2020-2023, the most recent being in March 2023, along with the installation of multiple mini-split HVAC systems throughout 2022-2023, and an electrical service upgrade to 400 amps in July 2023. Sustainability features include three separate solar PV installations between 2022-2025, with the most recent project for 9 modules rated 3.82 kW issued in January 2025. The property's maintenance history shows regular upkeep, with work completed on garage door modifications, various bathroom and kitchen upgrades, and the relocation of the electrical fuse box in 2019.

Historical records indicate routine housing inspections in 1999 and 2003 with no active violations. A significant tenant buyout occurred in December 2020 with one tenant receiving $80,000, though the impact on unit configuration is unclear as no unit count change was indicated. Recent 311 calls primarily relate to street-level issues such as graffiti and debris, while the building itself has no recorded major complaints or violations in recent years, suggesting generally good maintenance practices.
