Initial analysis

The 6-unit, 2-story multi-family residential building at 2840 Judah St in the Central Sunset neighborhood, owned by Gary & Maggie M Chew Revoc, has undergone several significant improvements and faced various challenges since its construction in 1964. Most notably, the building completed mandatory soft-story retrofits in 2017 and 2019, demonstrating compliance with San Francisco's seismic safety requirements (Tier 3), which included the installation of steel moment frames, tie beams, and shear walls at the ground floor. The building has a history of plumbing and water pressure issues, with multiple complaints between 2008-2009 regarding inadequate water pressure affecting showers, and violations related to hot water storage capacity. A routine housing inspection in 2011 and a complaint about possible illegal units in 2009 (resolved, confirming 6 units) are also on record.

Earlier building improvements include the replacement of 14 aluminum windows with vinyl insulated frames in 2003, and some minor maintenance issues have been documented through 311 calls, such as sidewalk defects, illegal postings, and graffiti removal, all of which have been resolved. The property experienced several fire safety-related violations in 2001, including issues with the fire escape drop ladder and combustible materials, though all were promptly abated within one month. While these historical issues suggest periodic maintenance needs, the building's most recent major work - the completion of the soft-story retrofit - indicates compliance with current seismic safety requirements. The property has consistently addressed violations and complaints in accordance with building regulations, with no active violations or complaints currently on file.

Risk rating

How 2840 Judah 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
23th percentile

Out of 814 buildings in this neighborhood, 627 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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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

12-Month severity forecast
No violation 55.5%
Moderate concern 17.0%
Severe concern 27.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
