Initial analysis

The 4-unit multi-family residential building at 505 36th Avenue in the Outer Richmond, owned by Wu Allen & Wuliu Joyce, is a 2-story structure built in 1958. The building's documented history shows some significant safety-related issues in 2003, when multiple violations were recorded under complaint number 200338139. These violations, all of which were abated by April 14, 2003, included problems with fire safety systems such as smoke detectors in the lobby and stairwells, fire proofing materials, and the fire escape drop ladder. The building underwent reroofing work in 2002, costing $5,140.

More recent history shows two fire department responses: one for a malicious false alarm and another for an unintentional detector activation, neither resulting in injuries. The property has generated several 311 calls between 2014-2020, primarily regarding abandoned vehicles (six separate reports), and two other non-building related issues - a garbage overflow incident in 2020 and an entertainment commission complaint in 2014. While the building had notable fire safety issues in 2003, it's worth noting that these were resolved within two months, and there have been no similar safety violations recorded in the subsequent 20 years.

Risk rating

How 505 36Th 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

Out of 1040 buildings in this neighborhood, 666 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 62.7%
Moderate concern 21.1%
Severe concern 16.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
