309-311 Cortland Ave, San Francisco, CA 94110

The property at 309-311 Cortland Avenue in Bernal Heights is a two-unit, two-story multi-family residential building with a ground-floor commercial space, constructed in 1923 and currently owned by Cortland Business Group LLC. The building's history shows significant improvements and modifications over the past two decades, including substantial renovation work in 2013 involving ADA compliance upgrades (restroom relocations, new lighting, and windows) with associated plumbing and electrical work totaling approximately $50,000. Other notable improvements include a complete reroofing in 2008, facade modifications in 2005, and various electrical upgrades including a 200-amp to 240-volt conversion in 2005 and a power installation for an A/C unit in 2004.

The building has experienced several unpermitted modification complaints over the years, most notably in 2013 regarding unauthorized work on doorways and concrete walls, as well as allegations of work beyond permit scope occurring at 3:20 AM. More recently, the property has had some maintenance and public service interactions primarily related to street and environmental issues, including noise complaints, illegal parking incidents, and various infrastructure concerns such as tree maintenance and sidewalk cleaning between 2023-2024. The building's planning history indicates previous attempts to modify its use, including a proposal to add "Other Entertainment" to its existing bar usage, though these efforts appear to have been resolved through the proper channels.

A notable fence was constructed in 2003 for sound isolation purposes, and the property underwent significant electrical system upgrades in the early 2000s to support commercial operations. The most recent major infrastructure work includes a sewer trap replacement completed in 2019. While the building has experienced several compliance issues in the past, recent 311 calls primarily relate to exterior and public space concerns rather than interior building conditions.
