Initial analysis

The 1404-1406 41st Avenue property is a two-unit, two-story multi-family residential building located in San Francisco's Outer Sunset neighborhood, constructed in 1945 and currently owned by the Moy Family Trust. The building has undergone several significant maintenance and repair projects over the past two decades, with the most recent major work being a $11,000 reroofing project completed in 2019. The property has a documented history of addressing structural issues, particularly with dry rot, with repairs completed in 1999, 2011, and earlier instances in 1992-1998, along with termite remediation in 1998. Major infrastructure upgrades include comprehensive plumbing work in 2010 affecting both units, specifically targeting kitchen, bathroom, and laundry room water systems, though some associated permits expired without record of completion.

Historical building complaints from January 1999 raised concerns about heating systems, window condition, and security features, though these issues were addressed and closed within several months. The property has experienced recurring issues related to exterior maintenance, as evidenced by multiple 311 reports throughout 2024-2025, primarily focused on garbage and debris removal from the vicinity, as well as some sidewalk maintenance concerns. While these exterior issues appear to be promptly addressed based on closure status, they suggest ongoing challenges with building surroundings maintenance. Recent complaints about garbage removal and sidewalk conditions are currently being monitored, with some cases still open for resolution.

Risk rating

How 1404-1406 41St 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
39th percentile

Out of 632 buildings in this neighborhood, 386 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Building age

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

DBI complaints, owner's portfolio

Complaints across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 67.3%
Moderate concern 16.9%
Severe concern 15.8%
