451-453 Tehama St, San Francisco, CA 94103

The 451-453 Tehama Street building, located in San Francisco's South of Market neighborhood, is a 2-story multi-family residential building constructed in 1913, originally containing 4 units and currently undergoing significant expansion. The property is undergoing substantial modifications, including the addition of 5 new dwelling units, with construction work progressing through 2024. Recent permits indicate corrections to previously approved permits, including adjustments to unit counts and front stairs.

The building has undergone important safety improvements in recent years, including the installation of a new fire sprinkler system in 2022 (costing $72,500) and an upgraded fire alarm system to comply with city fire safety codes. Previous improvements from 2019-2021 included voluntary soft-story retrofit work, bathroom remodeling, and the installation of new radiant heat systems in lower units. The property has experienced several construction-related issues and code violations throughout its history. In 2023, there was a complaint about prolonged street disruption and accessibility issues during construction.

Multiple plumbing and expired permits have required corrections or re-inspections between 2022-2023, and there were several building complaints in 2021 regarding construction practices and debris management. Historical violations from 2004-2007 included building security, weather proofing, and fire safety concerns, though all these issues were abated by 2005. The property has also experienced recurring issues with street maintenance and debris management, as evidenced by multiple 311 calls in late 2024, though these primarily relate to street conditions rather than building safety. While the building has maintained active permits for major improvements and safety upgrades, the frequency of expired permits and construction-related complaints suggests ongoing challenges with project management and regulatory compliance.
