Initial analysis

The 4-unit multi-family residential building at 1812 47th Avenue in San Francisco's Outer Sunset neighborhood is a 2-story structure built in 1965, currently owned by the Tom Family Trust. The building has undergone several significant renovations and maintenance work over the past two decades, with the most recent major updates including window replacements in 2019 (upgrading four street-facing windows to aluminum sash), garage door replacement in 2016, and reroofing in 2013. A comprehensive gas pipe system upgrade in 2012 improved safety across all units, while a 2004 repair addressed dry rot in the lightwell.

The building experienced a cluster of maintenance and safety issues in 2004, when multiple violations were recorded including concerns about floor covering, window frames, possible water intrusion, and a potentially unsafe fence – all of which were abated by May 2004. A safety-related complaint from 2010 noted expired fire extinguishers and rusted gas pipelines in the garage, though these issues were also marked as not active. Recent years have primarily seen parking-related incidents in the immediate vicinity, with multiple reports of sidewalk parking between 2020-2023, though these external matters do not directly impact building conditions. The property's maintenance history shows a pattern of regular upkeep, with all recent building permits showing "Complete" status, suggesting responsive management to maintenance needs.

Risk rating

How 1812 47Th Ave'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
23th percentile

Out of 632 buildings in this neighborhood, 487 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 49.9%
Moderate concern 24.8%
Severe concern 25.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
