1503 Golden Gate Ave, San Francisco, CA 94115

The property at 1503 Golden Gate Avenue in the Alamo Square neighborhood is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Tommaso & Dorte Trionfi. The building has undergone several significant improvements over the past decades, with the most recent being a $59,000 window replacement project in 2022 involving seven street-facing windows with modern tempered glass and improved energy efficiency ratings (U-factor <0.30).

The second floor bathroom received a complete remodel in 2016, including fixture and finish updates, along with associated plumbing and electrical work, totaling approximately $9,800. Earlier maintenance work in 2007 addressed various structural issues, including rebuilding a damaged rear deck, repairing water-damaged walls, reroofing, and addressing dry rot on approximately 200 square feet of side walls, with these projects collectively costing about $27,200. The property's maintenance history shows regular upkeep and modernization efforts by its owners, though there was one notable incident involving illegal short-term rental activity that was officially abated.

An expired permit from 1989 for adding a bathroom and closet to the second floor is on record, though it is unclear if this work was ultimately completed. The recent window replacement project in 2022 was completed under the supervision of Permit Services, Inc. (Jennifer Ferrando), receiving proper administrative certification of appropriateness, indicating compliance with local preservation standards.
