140-142 Sadowa St, San Francisco, CA 94112

The property at 140-142 Sadowa Street is a one-story, multi-family residential building located in the Oceanview neighborhood, containing two units and built in 1908. The building has experienced several significant permit and violation issues over the past two decades. Most notably, there have been multiple unauthorized dwelling unit constructions and subsequent legalization attempts. In 2016, a significant effort ($100,000) was made to legalize an unauthorized unit with a kitchen, three bedrooms, and two bathrooms on the ground floor, though this permit was ultimately cancelled.

A 2017 permit to add an address to the residential unit was issued for $244. More recently, in February 2022, the electrical service panel was upgraded to 200 amps. The building has faced persistent maintenance and safety concerns, particularly in 2017 when multiple violations were recorded regarding mold/mildew on ceilings and walls, water-damaged ceilings, and walls requiring repair and repainting. These violations were eventually abated in February 2017.

The property has also experienced recurring sewer issues, with multiple sewer backup incidents reported through 2024, most recently in September 2024. Recent 311 calls from 2024 show ongoing concerns with illegal parking, including vehicles parking on sidewalks, and reports of overhead obstruction hazards. The property's history includes various complaints about unauthorized construction, including a 2014 complaint about multiple sheds exceeding the allowed size, and a 2017 complaint about a non-permitted detached structure with numerous code violations including improper electrical, plumbing, and construction work. The building's complex history of permit violations, attempted legalizations, and maintenance issues suggests persistent challenges with building code compliance and infrastructure maintenance, particularly regarding unauthorized dwelling units and plumbing systems.
