3340-3342 23rd St, San Francisco, CA 94110

3340-3342 23rd Street is a two-story, three-unit multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1878 and currently owned by Joan Mariner, the property has undergone several maintenance and safety-related improvements over the years.

Most recently, in 2020, the building received a $15,000 reroofing project, which was completed successfully. The building has experienced two notable safety concerns in the past: a mold and leaky window issue with improper weatherstripping and electrical outlet problems that were reported in 2010 and took approximately two years to resolve, and a dry rot repair project for back stairs, steps, and handrail that was completed in 1992. The property has a history of multiple fire safety system checks and minor incidents, primarily involving smoke detector activations and confined cooking fires, though none resulted in civilian injuries.

Various sidewalk and street space permits have been issued over the years, with the most recent being in 2018. Recent activity around the property, as evidenced by 311 calls, suggests external maintenance has been required, including graffiti removal and responses to illegal parking issues in the area, though these do not directly impact the building's internal conditions. The building's maintenance history shows regular attention to infrastructure needs, including a sidewalk repair project from 2000 and the retention and repair of exterior stairs and garden wall in 1992.
