137-139 12th Ave, San Francisco, CA 94118

The property at 137-139 12th Avenue, owned by the Moreno Trust, is a two-unit, two-story multi-family residential building constructed in 1913 in the Lake - The Presidio neighborhood. The most significant recent development is the 2022 permit for legalizing an unauthorized dwelling unit (UDU) under Ordinance 43-14, which involved relocating an unpermitted kitchen that had been converted from a laundry space, along with installing comprehensive NFPA 13 fire protection on the entire ground floor, with a project cost of $95,500.

This followed several substantial improvements between 2003 and 2007, including complete reroofing work ($9,785) in 2003, the addition of a bedroom, laundry room, and full bathroom on the ground floor ($26,000) in 2005, electrical upgrades including new service installation ($2,000) and comprehensive electrical work for ground floor additions, plus kitchen and bathroom remodeling on the second floor ($30,000) in 2006. The building's recent history includes routine maintenance and some community-related incidents, such as multiple 311 calls for street cleaning (2016, 2017, and 2020) and parking enforcement issues (2020).

Earlier records show some minor urban maintenance concerns like graffiti (2015) and an abandoned vehicle report (2015), all of which were resolved promptly. The property's documented improvements suggest ongoing investment in maintaining and upgrading the building, with particular attention paid to bringing previously unpermitted spaces into compliance with current regulations. The UDU legalization project appears to be the most substantial recent modification, significantly increasing the building's living space while incorporating modern safety features.
