136-140 26th Ave, San Francisco, CA 94121

The three-unit residential building at 136-140 26th Avenue, owned by Silvia & Marcelo Weinberger, is a three-story flats and duplex structure built in 1905, currently holding a multi-family residential use designation. The property has undergone significant improvements over the past decade, most notably in 2017-2018, when comprehensive fire safety systems were installed, including a complete NFPA 13 sprinkler system ($30,000) and a new sprinkler monitoring system ($3,000). During this period, major renovations were undertaken including window replacements, interior layout reconfigurations, and the installation of new furnaces.

The building received extensive electrical upgrades in late 2016 with a complete rewiring, 100-amp service upgrade, and installation of modern amenities across all units. Historical records show that the property underwent a series of housing inspections in 2005-2007, during which several violations were recorded and subsequently resolved by 2008, including issues related to stairs, fire safety, security, and lead paint concerns. The building's plumbing infrastructure was notably improved in 2013 with a complete sewer drain replacement. Recent activity (2024-2025) has primarily involved routine municipal services, including graffiti removal, parking enforcement, and utility maintenance, with one plumbing issue related to a sewage backup in December 2024.

Two tenant buyouts were recorded in 2015 at this address, with compensation amounts of $45,068.80 and $53,000.00 respectively. The property has maintained compliance with building codes since the 2005-2007 violation period, and recent inspection records (2023-2024) show only routine maintenance and service calls. The Weinbergers have shown ongoing investment in maintaining and upgrading the property, particularly its safety systems and modern amenities, while historical compliance issues appear to have been adequately addressed. The building's recent history has been relatively quiet in terms of major repairs or violations, with most recent permits being for routine maintenance and system upgrades.
