21 Mirabel Ave, San Francisco, CA 94110

The property at 21 Mirabel Ave in Bernal Heights is a 2-story multi-family residential building constructed in 1900, containing three units and currently owned by the James K Dotson Family Trust. The building has experienced several significant maintenance and safety issues over the years, with the most recent concerns centered around stair and structural repairs. In 2014, repairs were made to stairs at the rear of the building following a notice of violation, while previous issues included dry rot repairs in 2007, basement joist replacements in 2008, and multiple stair-related repairs between 2004 and 2014.

The building has also faced several housing code violations, including a complaint in 2014 regarding unpermitted structural work, and a 2006 complaint about inadequate heating systems that was addressed through the installation of wall heaters and a new 100-amp electrical service. Historical complaints and violations suggest ongoing maintenance challenges, particularly regarding building safety and unit habitability. A 2007 complaint documented multiple interior problems in unit B, including water damage, plumbing issues, and mold, while other complaints have addressed concerns about common area maintenance, security, and unauthorized unit modifications. The building's maintenance history includes various electrical upgrades and multiple building permits issued for repair work, indicating ongoing efforts to maintain compliance with safety standards.

While recent 311 calls from 2016-2019 have primarily concerned street-related issues such as abandoned vehicles and street cleaning, these are external to the building itself. The property has undergone various structural and safety improvements over the years, including the installation of wall heaters in 2007 and electrical system upgrades in 2006, though some permitted work has been marked as cancelled or expired. The building's age and history suggest it has required regular maintenance to address both routine wear and unexpected repairs, with particular attention needed for exterior elements like stairs, decks, and water ingress issues. The most recent major building-related incidents, from 2014, involved both structural repairs and a complaint about unauthorized construction work, indicating ongoing attention to proper permitting procedures and construction oversight.
