51 Prosper St, San Francisco, CA 94114

The two-story, 5-unit multi-family residential building at 51 Prosper Street, owned by Metz Thomas W & Brightman D, has undergone significant improvements since its construction in 1906. Most recently, in March 2024, work was issued to merge apartments 2 and 5, including adding a staircase and converting an existing kitchen to a bedroom. The building has seen substantial upgrades to its systems over recent years, including a $50,000 electrical panel upgrade in 2022 to a 400-amp system with individual meters for each unit, and comprehensive bathroom and kitchen remodels for Units 3 and 4.

In 2022-2023, dedicated circuits were installed for new ovens in Units 3 and 4. The building completed mandatory soft-story seismic retrofitting in 2015 as a Tier 3 property. Historical maintenance issues have included several concerning complaints between 2002 and 2013, primarily related to safety concerns such as inadequate heating, security violations, and egress issues.

These problems, including heating system failures and security concerns, were generally addressed within a few months of being reported. Significant structural work was performed in 2013, including partial foundation replacement and repairs for termite damage, along with various electrical and plumbing upgrades. The property has maintained compliance with all major building codes since completing the soft-story retrofit, though there was notable work required in 2022-2023 to modernize the building's electrical infrastructure and address various unit-specific improvements, suggesting ongoing investment in building maintenance and resident comfort. Several 311 calls have been logged for the address in recent years, primarily related to parking issues and street cleaning, though these are typical for urban properties and not directly related to building conditions.
