Initial analysis

The property at 543 6th Avenue in San Francisco's Inner Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1907, currently owned by the Larry & Rossana Wong Trust. The building's maintenance record shows one significant structural improvement in recent years, a reroofing project completed in 2018 at a cost of $9,500. The property has experienced a cluster of parking-related issues in late 2023, with multiple reports of driveway blocking incidents between November 21-27, 2023, involving different vehicles including a gray Honda and a black Buick Enclave, with at least one citation issued. Additionally, there were two parking enforcement responses related to scooters and illegal parking in the same period.

The 311 call history demonstrates regular interactions with city services over the past decade, including a 2024 Muni service feedback case that was resolved, a 2023 garbage can service request that was completed, and older incidents such as illegal postings on sidewalks (2017) and offensive graffiti on a pole (2011) that were addressed by city departments. While the building's major structural elements appear to be maintained, as evidenced by the recent roof work, the property's immediate vicinity has experienced recurring parking challenges in recent months, suggesting ongoing issues with street parking management in the area.

Risk rating

How 543 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

Out of 1723 buildings in this neighborhood, 414 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.

Building age

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

Building permits, owner's portfolio

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

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 82.6%
Moderate concern 12.9%
Severe concern 4.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
