898 Carolina St, San Francisco, CA 94107

The property at 898 Carolina Street in Potrero Hill is a three-story multi-family residential building constructed in 1906, currently owned by the Neill Sullivan Trust. The building has undergone numerous significant improvements over recent years, with the most substantial work occurring between 2017-2020, including a major renovation in 2017 that involved raising the roof height to create additional habitable space, followed by comprehensive interior remodeling in 2020 that added an extra bedroom.

The building's safety systems were substantially upgraded in 2020 with the installation of new fire sprinkler systems, including both domestic and 13D systems with 39 new pendant sprinklers, demonstrating compliance with modern safety standards. Recent improvements to the property include the installation of a mini-split system (July 2024), electrical work for two A/C units (August 2024), and a new garage door (2022). The building has also received important infrastructure upgrades, such as upper lateral sewer replacement (2022) and the installation of a combination boiler for domestic hot water and radiant floor heating (2020).

While there have been several complaints during construction in 2020 regarding noise and safety issues, these appear to have been addressed. The property has maintained compliance with building codes and regulations, with all significant permits marked as complete, though there was one active construction-related complaint in 2020 about a generator running at the site. Recent 311 calls have primarily concerned external issues such as graffiti and street cleaning, rather than building-specific problems.
