1539-1543 Larkin St, San Francisco, CA 94109

HJC Enterprises LLC owns this 5-unit, 4-story multi-family residential building located at 1539-1543 Larkin Street in the Nob Hill neighborhood. Built in 1908, the property has undergone several significant upgrades in recent years, with the most substantial being a comprehensive fire alarm system upgrade in early 2023 costing $15,000 to meet current safety codes.

The building completed its mandatory soft-story retrofit in 2016 (as a Tier 3 building) at a cost of $93,000, demonstrating compliance with San Francisco's seismic safety requirements. Recent improvements include the installation of new windows throughout the building in 2016, both visible and non-visible from the street, featuring energy-efficient Low-E, argon-filled, double-glazed glass. Unit renovations have been conducted systematically, including a 2016 remodel of Unit 1's kitchen and bathroom, and the addition of a laundry room in 2018.

The building's infrastructure has been regularly maintained, with records showing multiple updates to plumbing systems, including water heater and meter installations, HVAC systems, and electrical upgrades. The only notable building violation on record was resolved in 2017 regarding an unpermitted boiler operation, which was abated within months. While there have been several 311 calls regarding the property's surroundings (primarily about parking and street cleaning issues), these were mostly external matters not directly related to the building's condition or management.
