1511 Lyon St, San Francisco, CA 94115

1511 Lyon Street is a two-unit, two-story multi-family residential building located in Lower Pacific Heights, owned by Tad A Devlin and constructed in 1900. The property has undergone significant renovations and maintenance work over the past decade, with major improvements occurring between 2016-2019 including comprehensive electrical upgrades (200-amp service, rewiring of both units), plumbing renovations (kitchen and bathroom remodels, appliance replacements), and infrastructure improvements such as sewer line replacement in 2010.

Several building complaints were filed during 2017-2018 periods, particularly related to construction activities, including issues with unpermitted work, improper waste management, and a reportedly unauthorized tree removal. A notable tenant buyout occurred in December 2016, involving two tenants and totaling $35,040. The building's more recent history (2020-2024) shows regular maintenance and compliance with city regulations, though there have been recurring issues with street-related matters including parking violations and garbage concerns, as evidenced by multiple 311 calls.

Most recently, in 2024, there have been reports of encampments and debris issues in the vicinity. The property has undergone thorough electrical and plumbing system upgrades, with multiple permits issued to address various systems throughout both units, while some permits from 2016-2018 expired without completion, including a significant electrical upgrade to Unit A. The building's maintenance history suggests active management, though the pattern of expired permits and ongoing exterior maintenance issues indicates some challenges with permit compliance and exterior upkeep.
