The two-unit residential building at 1564-1566 Green Street in Cow Hollow, owned by Alexander H. Hachiya, has undergone significant improvements and modifications since 2021. Most notably, the property completed major safety upgrades in 2024, including the installation of a comprehensive sprinkler system ($10,000) and a sprinkler monitoring system ($12,700).

The building has seen substantial vertical expansion and modernization, with the addition of a fourth floor in 2024, installation of mini-split HVAC systems, and hydronic heating systems for both units. The property underwent comprehensive interior remodeling in 2021-2022, converting storage space into habitable areas, adding a roof deck for the third-floor unit, and updating kitchens and bathrooms in both units. Several exterior improvements were made, including siding replacement, roof modifications, and voluntary structural improvements. The building experienced some construction-related issues in late 2021, with multiple complaints about unsafe debris removal practices during renovation work, though these complaints were ultimately resolved.

More recently, there have been recurring issues with driveway blocking near the property, as evidenced by multiple parking enforcement calls between September 2024 and January 2025. The property has maintained an active improvement trajectory, with all major building permits marked as complete, though some plumbing and electrical permits from 2021 and 2022 expired and required renewal for final inspection purposes. Recent improvements include additional bathroom facilities and a wet bar installation completed in October 2023, along with comprehensive electrical and plumbing upgrades. The building received approval for condo conversion under the DPW referral process, indicating compliance with relevant housing regulations.
