140 20th Ave, San Francisco, CA 94121
The 18-unit, 3-story multi-family residential building at 140 20th Avenue, constructed in 1927, has undergone several significant renovations and improvements over recent years. Most notably, there is a current permit pending (filed January 2021) to add three units on the first level by converting existing parking spaces. Between 2018 and 2020, the building saw substantial interior upgrades including the renovation of units 104, 106, 202, and 306, with improvements to bedrooms, bathrooms, kitchens, and electrical systems, along with a comprehensive fire alarm system upgrade to meet 2021 code requirements.
Recent maintenance issues have emerged, with complaints in late 2022 about water heating problems and ceiling leaks in unit 104, and a current open violation (as of December 2023) related to sleeping area requirements. The building has a history of fire safety concerns, particularly in the mid-2000s, with multiple violations regarding fire escapes, combustible storage, and fire proofing that were resolved by October 2006. A more recent fire escape violation was logged in September 2022 but was determined to have no merit. The property has also experienced some tenant concerns during construction periods, notably in March 2020 regarding social distancing compliance.
While the building appears to be well-maintained overall, with numerous modernization projects completed in recent years, the current open violation regarding sleeping area requirements and recent maintenance issues suggest there are still some outstanding compliance matters that need attention. The building's recent history has been relatively quiet in terms of major violations or complaints, with most recent 311 calls relating to parking and street cleaning issues rather than building-specific problems. Multiple Zoning Verification Requests have been processed for the address, indicating regular updating of records and compliance checks. The property management has demonstrated ongoing investment in the building's maintenance and modernization, as evidenced by the substantial number of completed permits and improvements over the past five years.
