Initial analysis

The two-story multi-family residential building at 2809-2811 Harrison Street in the Inner Mission, owned by Winzer Marie C, was constructed in 1914 and contains two units. The building's maintenance history reveals some significant infrastructure issues, particularly with the sewer system, showing three documented sewage backup incidents between late 2023 and early 2024, all of which were resolved by PUC Sewer Operations. The building underwent dry rot repairs to stairs and landing in 2004, and has had recent street-related permits in 2008. The property has experienced ongoing challenges with waste management, as evidenced by multiple 311 calls in early 2024 regarding garbage receptacles (toters) being left out continuously, with enforcement actions initiated and follow-ups scheduled. There have been several reports of street cleaning needs, including garbage and debris incidents in July and November 2024.

From a safety perspective, the building has had three fire complaints related to combustible materials in October 2013, though all were recorded as having no merit. Notably, there was one recorded motor vehicle/pedestrian accident incident involving the property, though no civilian injuries were reported. The most recent infrastructure work was documented in July 2024, when utility excavation work was being conducted on the sidewalk and curb, with residents informed of temporary conditions and a final paving date scheduled for August 2024. While the building is relatively old, its documented issues primarily relate to exterior maintenance and historical fire complaints rather than structural concerns, though the recent sewer issues may warrant attention.

Risk rating

How 2809-2811 Harrison 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
88th percentile

Out of 2380 buildings in this neighborhood, 286 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 69.0%
Moderate concern 15.8%
Severe concern 15.1%
