593-599 Mariposa St, San Francisco, CA 94107

The property at 595 Mariposa Street is a five-story, multi-family residential building containing 20 units, constructed in 2017 under the ownership of Soma Acquisition LLC. The building has undergone significant infrastructure upgrades since its completion, including plumbing improvements such as a new combined storm and sewer system, water pipes, and water heaters installed in 2017-2019.

The building has experienced recurring issues with boiler permits, with violations filed in 2020 and most recently in March 2024 for two boilers (serial numbers 1722106283289 and 1722106283290), though these violations were abated within weeks. A notable accessibility concern was documented in June 2021 regarding the front entrance and elevator access for disabled individuals, particularly during a period when the elevator was reportedly non-functional.

The building's fire safety systems have been the subject of multiple violations and complaints, including issues with alarm systems, fire sprinkler systems, and blocked exits between 2010-2024, with the most recent violations concerning the ERRCS (Emergency Responder Radio Coverage System) in 2024. Recent 311 calls from January 2025 indicate ongoing concerns with garbage management and encampments in the vicinity of the property. The building appears to have maintained compliance with most building permits, including recent ERRCS upgrades in 2021 and final inspections in 2022, though there have been multiple revisions and confirmations regarding various systems throughout its operational history.
