124-128 Fillmore St, San Francisco, CA 94117

The 124-128 Fillmore Street property is a three-story, three-unit multi-family residential building constructed in 1902 and currently owned by the David Scott Nale 2000 Trust. The building has undergone significant recent modifications, most notably the legalization and upgrade of a basement accessory dwelling unit (ADU) between 2018-2022, including the installation of a residential fire sprinkler system, electrical and plumbing work, and associated safety monitoring systems. The building's history includes several concerning events between 2015-2017, particularly related to construction activities, with multiple complaints about excessive noise levels (reportedly exceeding 80 decibels), potential lead dust hazards, and safety concerns during rooftop deck construction.

While these issues were labeled as "Not Active" after investigation, they indicate a period of significant tenant disturbance. The building has also experienced various maintenance and compliance issues, including blocked exits (2015) and multiple fire safety system activations, though no injuries were reported. Historical complaints from 2000-2009 included issues with unauthorized short-term rentals, concerning a possible conversion from a three-unit building to transient rental use, though these violations appear to have been addressed.

Recent activity at the property primarily consists of routine maintenance and cleanup actions, as evidenced by multiple garbage and debris-related 311 calls in late 2024, though these are generally not indicative of serious building issues. The building's permits and construction history show substantial investment in upgrading systems and legalizing previously unauthorized spaces, including work to comply with physical inspection reports and various safety improvements. The most recent significant building work appears to have been the 2022 completion of fire safety monitoring systems, which followed previous permits for ADU-related improvements. The property has maintained an active permit history, suggesting ongoing maintenance and compliance with regulatory requirements, though some permits from 2018-2021 show as expired or renewed, indicating typical administrative processes associated with building modifications.
