54-56 Manzanita Ave, San Francisco, CA 94118

The two-unit residential building at 54-56 Manzanita Ave, located in the Jordan Park/Laurel Heights neighborhood, is a two-story flats and duplex structure built in 1949 and currently owned by Harbin West Hldgs LLC. The property has undergone several significant maintenance and improvement projects over the years, with the most substantial being a complete reroofing in 2014 costing $20,000, and a 200-amp electrical service upgrade completed in 2018.

The electrical system received attention in 2018, including both street space work and an upgrade to modernize the building's infrastructure. Historical records show previous improvements including aluminum window installations in 1987 and 1991, though one of these permits expired. The building's maintenance record indicates regular upkeep, particularly with the roofing system which has been addressed multiple times over its history.

Two notable infrastructure-related incidents were recorded: a flooding incident in October 2019 involving a leaking gate valve on the street, which was resolved by PUC Sewer Operations, and a demolition work permit in 2017 related to electrical service upgrades that required sidewalk safety measures. The most recent activity related to the property was a noise complaint filed in October 2023, though this appeared to be an informational report rather than a formal violation. The property's permit history suggests proactive maintenance and upgrading of essential systems, with no recorded building code violations or safety concerns in recent years.
