1227 York St, San Francisco, CA 94110

The property at 1227 York Street in San Francisco's Inner Mission neighborhood is a two-story, four-unit multi-family residential building constructed in 1900, currently owned by Renee M. Tomasello. The building has undergone several significant renovations over the past two decades, most notably in 2008-2009 when multiple improvements were made including window replacements, plumbing updates, and electrical work.

During this period, the property experienced a serious violation in February 2008 regarding unauthorized construction of a possibly illegal rear building, which included unpermitted plumbing and electrical work; this was ultimately resolved by March 2009. A routine housing inspection in January 2009 revealed multiple safety and security issues including concerns about combustible storage, exterior door self-closing devices, handrails, entry doors, and fire safety equipment, though these violations were also abated by March 2009. The building's maintenance history shows regular upkeep, with permitted work including window replacements in 2008 and 2009, and various improvements to both the front and rear buildings.

The property has been subject to several 311 calls in recent years, primarily related to street cleaning and parking issues, with the most recent calls regarding garbage and debris in December 2024. Previous complaints from 1999 and 2008 suggested concerns about illegal unit occupancy and unauthorized renovations, though these issues were resolved. Planning records confirm the resolution of the unauthorized construction and permit violations from 2008, with the status listed as "Closed - Abated." The building has been maintained with various permitted improvements, though the concentration of violations in early 2009 indicates a period of significant regulatory scrutiny that appears to have been successfully resolved.
