250-254 Carl St, San Francisco, CA 94117

The property at 250-254 Carl Street is a 3-unit multi-family residential building constructed in 1906, currently owned by Charles A & Gloria V Nick F. The building has experienced several significant issues over its history, with the most pressing concern being an active complaint from 2007 regarding an unauthorized conversion of basement storage rooms into a sleeping unit with numerous safety violations, including inadequate fire resistance materials, unapproved electrical wiring and plumbing, improper ventilation and lighting, missing smoke detectors, lack of permanent heat source, and inadequate emergency exits. The building has undergone various improvements and maintenance work over the years, including permitted construction of a wood deck in 2021, horizontal addition work (2010), electrical system upgrades in 2007, including furnace replacements and common area modifications, and historical repairs such as plumbing work in 2000 for water damage.

Multiple fire and safety violations were noted in 2006, including the need for fire proofing repairs, fire extinguishers, and security improvements, though these were eventually resolved. Recent activity at the property has primarily consisted of municipal services addressing exterior maintenance issues, with numerous street cleaning requests for garbage and debris removal recorded between 2023 and 2025. There have been sporadic complaints about noise and parking issues in the vicinity.

There was also a period of concern regarding unauthorized short-term rental activity in 2014, though this appears to have been resolved. The building's maintenance history shows a pattern of addressing infrastructure needs, with completed work including basement wall reinforcement (1995), reroofing (1994), and structural improvements in the basement (1987). While some older building code-related permits from the 1980s are listed as expired, the most recent building improvements have generally been permitted or addressed through proper channels, though the ongoing basement unit violation from 2007 remains a notable concern in the building's history.
