21 Napier Ln, San Francisco, CA 94133

The three-story, three-unit multi-family residential building at 21 Napier Lane in Telegraph Hill, owned by Aaron Peskin and Nan Shanahan, has a documented history dating back to 1900. The property has undergone several significant structural and maintenance improvements over the years, with the most recent major work being a sewage backup issue in 2022 and water main leaks in 2020.

In 2009, substantial repairs were made to address dry rot on front and rear decks/stairs, while earlier foundation work was attempted in 2004 with permits for both minor repairs and additional foundation work valued at $8,000, though these permits eventually expired. The building's maintenance record shows regular attention to water heaters, with replacements documented in both 2015 and 2018, and electrical improvements made in 2004. Historical records indicate the building has received appropriate oversight and inspections, including routine inspections in 2001 and 2005 by Housing Inspection Services.

A complaint was filed in 2009 regarding an unauthorized detached wooden structure at the back of the building, though this was quickly addressed within one month. The property's exterior has received attention for maintaining its historical character, with planning records showing approved permits for exterior repairs and alterations, including skylight installation, in compliance with the Telegraph Hill Historic District requirements. Regular maintenance of decks and stairs has been a recurring theme, with multiple repairs documented between 1997 and 2009, suggesting ongoing attention to common area safety features.
