737-739 Guerrero St, San Francisco, CA 94110
The property at 737-739 Guerrero Street is a two-unit, two-story multi-family residential building constructed in 1907, currently owned by the Estate of Marjorie C Smith. The building has undergone significant improvements and structural work in recent years, with the most substantial project being the addition of a state-mandated ADU (Accessory Dwelling Unit) in 2022, consisting of two bedrooms, two bathrooms, kitchen, and living room, along with mandatory seismic strengthening improvements. This $294,729 project received proper permits and is currently in progress, with electrical and plumbing work continuing into 2024.
The building has seen comprehensive modernization efforts between 2021-2022, including major renovations to both units' kitchens and bathrooms, laundry room remodels, and necessary repairs to address dry rot issues in joists, studs, and floor sheathing. Seismic safety improvements were completed in mid-2022, including foundation replacement and structural upgrades. Historical records show earlier renovations in 2008 involving stair repairs and window replacement, as well as two minor violations related to unauthorized stair rebuilding which were promptly resolved.
A tenant buyout occurred in February 2022 for $96,500 involving two tenants. The property has experienced some recent challenges with street cleaning issues, as evidenced by multiple 311 calls throughout 2023-2024 regarding urban waste and debris, though these are external to the building itself. While these external cleanliness issues are notable, they do not directly reflect on the building's current condition or management. The extensive recent improvements and structural upgrades suggest active maintenance and modernization efforts by the current ownership.
