239 Clinton Park, San Francisco, CA 94103

239 Clinton Park is a two-unit residential building constructed in 1919, located in San Francisco's Mission Dolores neighborhood. The property, owned by Kose Rickmer, has undergone significant modifications and experienced several notable events in recent years. Most concerning were a series of trespassing incidents in August 2022, when multiple complaints were filed about unauthorized individuals accessing the building and neighboring properties, allegedly using the structure while it was undergoing renovations.

This led to building violations related to unpermitted window installations. The property has undergone extensive improvements since 2019, including a major renovation project that aimed to add a fourth story and rear additions, though this work expired without completion under initial permits. Subsequent permits in 2021-2023 focused on essential safety upgrades, including the installation of a fire sprinkler system, new electrical service upgrades (including a 400-amp main panel with three meters), comprehensive plumbing improvements, and window replacements to comply with building violations.

The building's renovation history shows substantial investment in modernization and safety upgrades, with over $350,000 in construction costs since 2019, including the installation of a Mitsubishi heat pump system, complete plumbing system replacement, and various structural improvements. Recent maintenance issues include a sewage backup incident reported in October 2024, though this was resolved without major findings. The property's location has encountered periodic sanitation challenges in the surrounding area, with multiple reports of waste and general cleaning needs documented through 311 calls between 2022-2024, though these were mostly related to street conditions rather than building issues. While the building has undergone significant improvements, the prior security incidents and ongoing compliance requirements suggest continuing attention to building envelope and window performance is necessary.
