Initial analysis

829 York Street is a 2-unit, 2-story multi-family residential building constructed in 1912, currently owned by Daniel & Elizabeth L De Cab. The property has a history of unauthorized modifications and code violations, with the most significant ongoing issue being an active violation from 2013 (Case #201322371) that identified multiple safety and habitability concerns, including improper wiring and plumbing, lack of required smoke detectors, inadequate egress and fire safety features, and a possibly non-compliant third dwelling unit. Previous violations and complaints suggest persistent maintenance and safety concerns throughout the building's history, including security issues, water damage, pest infestations, and various interior surface problems.

Recent activity at the property has mainly involved exterior maintenance and security issues, with multiple 311 calls in 2024-2025 reporting hazardous conditions such as medical waste (needles) and garbage debris on the street. Building maintenance records show various historical repairs and improvements, including work completed in 1994-1995 for roofing, painting, and staircase repairs, as well as a completed wall replacement project in 2003. However, more recent attempts to address the building's unauthorized unit status have been unsuccessful, with a 2016 permit application to legalize the ground floor unit being cancelled. The combination of an active violation case, historical maintenance issues, and recent exterior cleanliness concerns suggests ongoing challenges with property upkeep and compliance with housing codes.

Risk rating

How 829 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, 809 are predicted to be safer.
