420 Lake St, San Francisco, CA 94118

420 Lake Street is a four-story, 6-unit multi-family residential building constructed in 1904, currently owned by Evelyn Lee. The property has undergone several significant improvements over the past two decades, with the most critical being a completed soft-story retrofit in 2018 (cost: $55,000), which brought the building into compliance with seismic safety requirements. Recent maintenance includes repairs to the top-level rear stairs in 2019 (cost: $8,000) due to issues with broken steps and deck.

The building has experienced recurring boiler and hot water system issues, with the most recent complaint filed in December 2022 regarding inconsistent hot water service, though this was eventually resolved in March 2023. The building's maintenance history shows attention to basic infrastructure, including a kitchen remodel in Unit 5 in 2015 (cost: $12,750), window replacements in 2012, and various plumbing and electrical upgrades. Historical violations from December 2003 related to fire safety and building maintenance were all promptly resolved within days, including issues with exterior lighting, wooden stairs, gas utility shutoff tools, and fire escape egress.

The property has maintained compliance with soft-story requirements and has a current certificate of final completion (CFC) issued. Recent 311 calls primarily relate to noise concerns during regular collection times and parking issues, which are not unusual for urban residential settings. While the building's age (119 years) presents typical maintenance challenges, the record shows regular attention to safety systems, building codes, and resident comfort, with most issues being addressed promptly.
