177 Cook St, San Francisco, CA 94118

The two-unit residential building at 177 Cook Street in the Lone Mountain neighborhood is a two-story flats and duplex structure built in 1941 and currently owned by Ching Ying Ma Wong Trust. The property has undergone significant recent improvements, with major renovation projects taking place from 2018 through 2024. In 2021, kitchen and bathroom remodels were completed in both units, featuring high-efficiency lighting, new kitchen hoods, and bathroom exhaust fans, with associated electrical and plumbing work costing approximately $30,000.

This work followed an earlier permit from 2017 that had expired. The building's electrical system received substantial upgrades, including a 200-amp service installation with two 100-amp subpanels per unit and 50-amp house meter, along with comprehensive rewiring of kitchens, bathrooms, bedrooms, hallways, and garage areas, with permits issued in 2018 and 2021. More recently, in November 2024, both units had their furnaces replaced with new Bryant 80% efficiency gas furnaces, completed successfully.

The property has experienced some maintenance issues in recent years, including a sewage backup incident in December 2017 and a sidewalk defect in April 2018 caused by tree roots. The sidewalk was inspected but ultimately resulted in an administrative closure. While there have been several parking-related complaints near the property (including vehicles parking on sidewalks in 2018 and 2021, and a blocked driveway in 2019), these incidents were typically resolved through enforcement action. The building's infrastructure updates, particularly the comprehensive electrical system overhaul and recent plumbing improvements, suggest that the property has received substantial attention to its basic systems, though some permits have expired and required renewal before completion.
