Initial analysis

The 813 York Street property in San Francisco's Inner Mission neighborhood is a three-story, multi-family residential building (duplex) owned by the Mulcahy Family Trust and constructed in 1904. The building is currently undergoing substantial interior renovations, with active permits issued in September 2024 for converting a den into a kitchen, remodeling the existing kitchen into a media room, and modifying a living room into a bedroom, along with associated bathroom work. Additional work related to this renovation includes plumbing and electrical updates. The property's maintenance history shows some attention to structural integrity, with dryrot repairs completed in 2014 affecting approximately 400 square feet, and a gas furnace replacement and ductwork installation completed in 2019.

The building's recent history has been marked by multiple 311 calls in 2023-2024, primarily relating to street cleaning issues with several reports of human or animal waste on or near the property grounds. These street cleaning incidents, while not directly related to building conditions, may affect the surrounding environment for residents. The property has maintained regular updates through permits and repairs, including historical attention to safety elements like stairs, though a repair permit from 1996 has since expired. A fire alarm system malfunction has been recorded with no civilian injuries reported. The consistent pattern of street cleaning calls suggests ongoing challenges with the immediate exterior environment, though these are municipal public space issues rather than building-specific concerns.

Risk rating

How 813 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.

Neighborhood percentile

Out of 2380 buildings in this neighborhood, 928 are predicted to be safer.
