679 4th Ave, San Francisco, CA 94118

The two-unit residential building at 679 4th Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1908, currently owned by Michael & Carmelita Tursi R. The property has undergone several significant maintenance and improvement projects over the past few decades, with the most recent notable work being filed in November 2022 for interior modifications including a bedroom and family room addition, installation of a two-burner electric cooktop and sink on the first floor, and decay repairs to rear stairs (less than 50% modification).

The building's infrastructure has seen substantial updates, including a complete sewer line replacement in 2015 and previous major repairs such as roof reconstruction in 1987 due to collapse concerns, stucco and steps repair in 1989, and modifications to reduce garage space from three to two off-street parking spaces. A permit application was also filed for adding a second kitchen within an existing unit at the ground floor, with specific limitations on appliances to meet building code requirements.

While there was a recent 311 call regarding loose garbage and debris in December 2024, this appeared to be a street cleaning matter that was resolved without necessitating further action. The building's maintenance history shows regular upkeep and infrastructure improvements, though prospective tenants should note the ongoing modifications as indicated by the filed permits.
