1035 De Haro St, San Francisco, CA 94107

The property at 1035 De Haro Street is a two-unit multi-family residential building in Potrero Hill, constructed in 1912 and currently owned by Roumila Tayeb. The building's recent history has been marked by several significant events, most notably a series of building code violations and compliance issues in 2019 that led to multiple correction orders. These violations included problems with heating systems, plumbing, window repairs, and water damage, though all were eventually abated by August 2020.

The property underwent substantial improvements in recent years, including the installation of a new ADU in 2020 ($40,000), complete plumbing upgrades in 2022-2023 involving tankless water heaters and drain pipe replacements, and electrical rewiring of the kitchen in 2022. The building has experienced several concerning incidents related to maintenance and safety. Most recently, in September 2023, there was a complaint about an unpermitted tankless water heater installation causing continuous loud noises and water leakage into a lightwell.

Prior to this, there were multiple complaints in 2019 regarding unpermitted work, including window replacement, construction noise, and various system installations. A notable investigation in 2019 confirmed the presence of an unauthorized unit in a rear detached structure, which had reportedly been used for long-term rentals. While all 2019 violations have been resolved, the 2023 plumbing installation complaint remains a recent point of concern. The property's maintenance history shows periodic attention to various systems, including heating equipment upgrades, plumbing repairs, and compliance with building codes, suggesting ongoing efforts to address infrastructure needs despite some history of unpermitted work and resultant complaints.
