Initial analysis

The two-story multi-family residential building at 575-577 6th Avenue in San Francisco's Inner Richmond district, owned by Carson & Irene Lee Yu Revocable Trust, has a significant history of recent regulatory compliance issues regarding unauthorized units. Built in 1912, this duplex structure underwent official remedial actions in 2015-2016 to address the illegal conversion of a garage space into a residence, which included the removal of plumbing fixtures (such as a wet sink and bathroom facilities) and electrical components associated with the unauthorized unit. These modifications were completed in accordance with complaints filed in December 2015 (Case #201585503 and #201586415) by the Housing Inspection Services division.

The property has experienced several maintenance and regulatory issues over the years, though none appear to directly affect habitability or resident safety. These include infrastructure matters such as a missing side sewer vent cover (2018), a sidewalk defect (2017), and multiple parking-related complaints (2023) including instances of unauthorized parking on public sidewalks and driveway blocking. All these issues were resolved through normal municipal channels, with no outstanding legal or safety concerns noted in recent records. The building's compliance history indicates proper response to regulatory requirements, with no recent building code violations or unauthorized unit complaints since the 2015-2016 period. The property's current designation as a two-unit dwelling is properly reflected in the records, following the official removal of the unauthorized ground floor unit.

Risk rating

How 575-577 6Th 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
64th percentile

Out of 1723 buildings in this neighborhood, 620 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.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

Estimated permit spend (past 7 years)

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

Building age

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

12-Month severity forecast
No violation 77.6%
Moderate concern 14.2%
Severe concern 8.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
