Initial analysis

The property at 236 3rd Avenue is a two-story, three-unit multi-family residential building located in San Francisco's Inner Richmond neighborhood, owned by the Helen Mar Chin Revocable Trust and constructed in 1980. The building's most significant issues arose in April 2004 during a routine housing inspection, which documented multiple fire safety violations including improper combustible storage in the garage, unaddressed combustible materials near parked vehicles, and missing smoke detectors in stairways. These violations resulted in several notices of violation (NOVs) but were ultimately abated by July 2004. A subsequent similar fire safety violation was recorded in 2010, though all violations from both incidents were eventually resolved.

More recent concerns include a 2019 complaint regarding unpermitted interior remodeling work being conducted by unlicensed contractors, though this complaint is now listed as not active. The building has generated several 311 calls over the years, primarily related to parking issues (including a blocked driveway incident in 2024 and a double parking complaint in 2019), as well as cases involving graffiti (2016) and tree root issues affecting property (2013) - though the latter was found to be nonexistent upon inspection. The property's record shows a pattern of fire safety compliance issues in the early 2000s, which were addressed at the time, but there have been no documented fire safety violations in recent years.

Risk rating

How 236 3Rd 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
88th percentile

Out of 1723 buildings in this neighborhood, 207 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.

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.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

12-Month severity forecast
No violation 80.2%
Moderate concern 15.5%
Severe concern 4.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
