527 Natoma St, San Francisco, CA 94103

The two-unit residential building at 527 Natoma Street, owned by the Cecil H Byrnes Revocable Trust, was constructed in 1986 and is classified as a Flats & Duplex property. The building has undergone two major maintenance projects over its lifetime, including a comprehensive window replacement project in 2020 costing $10,000, where 18 windows were updated with aluminum single-hung windows on the front facade and vinyl frames on the rear, meeting modern U-factor energy efficiency standards. Prior to that, in 2016, the property received a new roof through a project valued at $24,870.

Both of these improvements were properly permitted and completed according to city records. The property and its immediate vicinity have experienced recurring issues with street cleanliness and maintenance, particularly in 2023-2024, with multiple 311 calls regarding loose garbage and general cleaning needs. Noteworthy concerns include a medical waste incident involving needles reported in January 2024, though this was not directly within the building's property boundary.

There were also several incidents of abandoned vehicles and illegal parking in the vicinity during mid-2023, all of which were promptly addressed by city authorities. While these external maintenance issues have been documented through city service calls, they reflect neighborhood conditions rather than direct building management concerns. The building's maintenance record shows proper attention to major systems through permitted improvements, with no recorded building code violations or safety concerns in the available data.
