Initial analysis

1079 York Street is a two-story, multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1880, the property was originally designed as a one-family dwelling with occupancy over a garage, but underwent significant unauthorized modifications in the early 2000s that required subsequent legalization efforts. In April 2001, a complaint was filed documenting numerous life safety hazards in an unauthorized ground floor unit, including lack of heating, unapproved wiring and plumbing, missing smoke detectors, inadequate fire resistance materials, and emergency egress issues. These violations, along with plumbing problems noted in February 2000, were eventually addressed through proper permitting, with a building permit obtained in October 2001 ($40,000) to legalize the ground floor unit, followed by an electrical permit in May 2003. The property underwent further improvements in 2003 to address unauthorized deck construction, though more recent building complaints have not been documented.

Since 2023, there have been multiple 311 calls regarding the property's exterior conditions, including several reports of street cleaning needs and waste removal between May 2023 and September 2024, as well as instances of driveway blocking that resulted in citations. Notable recent activity includes a graffiti incident on the sidewalk in June 2023 and several general cleaning issues recorded throughout 2024. The building's legalization process was formalized through Planning records, with approvals obtained for off-street parking and the legalization of the additional dwelling unit under the Mission District Interim Controls, demonstrating compliance with city regulations following the unauthorized modifications. While the property has experienced various maintenance and enforcement issues in recent years, there are no current active building violations or complaints on record, suggesting that previous safety concerns have been adequately addressed.

Risk rating

How 1079 York St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
