Augrented Insights Report

The property at 1808 47th Avenue is a 2-story, 4-unit multi-family residential building located in the Outer Sunset neighborhood, owned by the Stephanie Mary Ng Revocable Trust and constructed in 1965. The building has undergone several improvements in recent years, including window and door replacements, siding repairs, and the installation of skylights in 2022-2023.

Notable maintenance work has been performed on the roofing in August 2023, and several fire safety and structural maintenance violations were documented and resolved in May-June 2020, including issues with carbon monoxide and smoke alarm compliance, egress obstruction, fire extinguisher requirements, and storage of combustible materials in the garage area. The building's historical maintenance record shows regular inspections and some concerns requiring attention, such as a 2020 complaint about a sealed exit and outdated smoke alarm batteries in Unit 3.

While the property has maintained compliance with building codes since the 2020 violations were abated, there have been recurring issues with parking violations in the vicinity, as evidenced by multiple 311 calls between 2022-2024, primarily related to sidewalk parking and construction equipment blocking spaces, though these were typically unable to be validated by responding officers. A resident complaint regarding construction noise from a neighboring project was filed in August 2022, though this was resolved within days. The building's recent maintenance history indicates active management, with three completed permits in the past two years focusing on window upgrades, roofing, and skylight installation.
