2831-2833 Pierce St, San Francisco, CA 94123

The property at 2831-2833 Pierce Street in Cow Hollow is a two-unit residential building constructed in 1949 and currently owned by Penwell Kent. The building underwent significant renovation work between 2018 and 2022, including a major remodel project completed in 2019-2020 that involved adding a fourth floor and installing a comprehensive fire safety system with 89 sprinkler heads, an underground fire line, and a dedicated sprinkler monitoring system. The renovation also included extensive plumbing updates, such as the installation of a new radiant heating system, multiple HVAC units, and comprehensive bathroom and kitchen renovations with new plumbing fixtures throughout.

The construction period from 2020 to 2022 generated multiple complaints from neighbors, particularly regarding noise, dust, and construction practices. Several complaints were filed in 2020 during the initial stages of construction, including reports of excessive noise, dust containment issues, and concerns about work continuing during shelter-in-place orders. More recent complaints in 2021-2022 focused on work being performed beyond the scope of permits and concerns about wastewater disposal practices.

The property underwent significant infrastructure upgrades during the renovation, including a complete electrical rewiring with 400-amp service, new sewer lines, installation of heat pumps, and various safety system installations. Most recently, in August 2023, the building's elevator motor was installed, indicating the completion of most major building systems work. While the building permit history shows numerous completed improvements, including recent plumbing updates and the installation of a new heating system, it's worth noting that some permits from 2021 expired without indication of completion status, though related work appears to have been subsequently addressed under new permits.
