Initial analysis

The property at 819 York Street is a two-unit, two-story multi-family residential building constructed in 1904, currently owned by Blaise Gary Andrew. The building has undergone several significant renovations and maintenance work over its history, with recent improvements including window replacements in 2017 and siding repairs at the rear of the building in the same year, costing approximately $13,000. The building experienced multiple violations and complaints during the early 2000s, particularly between 2000-2001, including issues with heating (insufficient system maintaining required temperatures), water damage, ceiling repairs, and unpermitted furnace installation, all of which were subsequently addressed and abated by January 2001. Earlier repairs included work on the back porch structure in 2001, gas heater installation in 2000, and multiple roofing projects in 1999-2000.

Recent activity at the property primarily consists of exterior maintenance and street cleaning responses, with several 311 calls between 2022-2024 related to general cleaning and waste removal on the street and sidewalk areas surrounding the property. The most recent building-related work was limited to the 2017 window and siding repairs, suggesting fewer structural issues in recent years. Since the major violations were resolved in 2001, there have been no recorded building violations or serious maintenance complaints regarding the property's interior conditions, indicating improved maintenance practices over the past two decades.

Risk rating

How 819 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, 976 are predicted to be safer.
