1864-1866 Stockton St, San Francisco, CA 94133

The two-unit residential building at 1864-1866 Stockton Street in Telegraph Hill, owned by Michael A & Rosemarie J Dav, has undergone several significant improvements since its construction in 1916. The most substantial work occurred between 2013-2014, when the property underwent a major penthouse expansion ($54,000), followed by voluntary structural upgrades and various interior modifications totaling approximately $30,000. These improvements included the installation of new stairs, lightwell modifications, and the addition of electrical and plumbing features such as a gas fireplace and roof drains.

A tankless water heater was also installed in 2010. The building's history includes some noteworthy incidents, particularly during the 2014 construction period when noise complaints were filed by adjacent residents regarding rooftop renovation works. There was also an incident in 2005 regarding a potentially hazardous deteriorated wood fence between the property and Lombard Street, which was promptly resolved within two weeks.

Recent records show a series of routine maintenance and street cleaning issues in the surrounding area, including multiple reports of waste and debris on the street in 2023-2024, though these are not directly related to the building's condition. The property has experienced some false fire alarms and detector activations in the past, but no actual fire incidents or civilian injuries have been recorded. Recent building activity has been limited to regular street space permits issued in 2014 and 2017, with no major violations or complaints on record in recent years.
