4418-4420 20th St, San Francisco, CA 94114

The property at 4418-4420 20th Street is a two-story multi-family residential building constructed in 1908, currently containing three units and owned by Hatton Trust. The building has undergone several significant improvements over the past two decades, including a comprehensive kitchen remodel in 2021 ($30,000), re-roofing in 2017 ($13,500), and a major renovation in 2010-2011 that included window replacements, plumbing updates, electrical work, and deck repairs.

The electrical system received an upgrade in 2014 with a 100-amp service riser replacement, and significant plumbing work was completed in 2011 including the installation of a high-efficiency furnace and laundry facilities. Of particular concern are several active building violations that have remained unresolved since they were filed in June 2014, related to stair safety, guardrails, and smoke/carbon monoxide alarm requirements. These violations include issues with stair riser openings, guardrails, handrails, and the need to file structural maintenance affidavits.

The building has undergone routine inspections by Housing Inspection Services in 1999, 2005, 2010, and 2014, with the most recent findings still pending resolution. While numerous maintenance and improvement projects have been completed over the years, these unresolved safety violations from 2014 represent the most significant ongoing concern regarding the building's condition and resident safety. The property has also been the subject of several 311 calls primarily related to tree maintenance and sidewalk issues between 2021 and 2024, though these are not directly related to the building's condition.
