1633-1639 Noriega St, San Francisco, CA 94122

The property at 1633-1639 Noriega Street is a three-story multi-family residential building with retail space, containing 4 units and constructed in 1951. In recent years, the building underwent significant improvements to enhance safety and compliance, most notably the legalization of an additional dwelling unit in 2016-2019, which included the installation of a comprehensive NFPA sprinkler system valued at over $65,000. This work was completed in stages, with the final components including sprinkler heads, monitoring systems, and associated electrical work all being successfully completed by early 2019.

The building’s systems were further upgraded in 2017 with the installation of a heat pump system, and all recent electrical work has been properly documented as complete. The building's maintenance history shows attention to both safety and habitability concerns, with previous violations from 2001 (including issues with fire safety equipment, egress pathways, and electrical fixtures) having been resolved by October 2001. A pest inspection in 2010 reported termite and mice infestation, though this was marked as not active within two weeks.

More recently, there was a fire alarm system violation issued in June 2019, which was abated within a week. The property has generated several 311 calls in recent years (2023-2024), primarily related to street cleaning issues and abandoned items outside the building, though these are typical urban maintenance matters rather than building-specific problems. Recent utility-related customer service interactions have been properly addressed.
