Initial analysis

The two-story, four-unit multi-family residential building at 506-508 8th Avenue in the Inner Richmond district was built in 1907 and is currently owned by Po Ka Tse & Shui W Tse Revo. The property has undergone several significant improvements, most notably a comprehensive renovation of Unit 2 in August 2014 that included updates to the kitchen and bathroom with new plumbing and electrical installations, costing approximately $30,000. The building received a new roof in 2006 at an expense of $6,000. In January 2017, the property underwent a routine safety inspection that revealed multiple violations related to safety equipment, including smoke detectors, carbon monoxide alarms, unit identification numbers, and security features. All of these violations were addressed and abated by February 2017.

The building's parking situation has been notably challenging in recent years, with numerous complaints filed about vehicles blocking driveways between 2019 and 2024. There have been at least ten such incidents, with several resulting in citations being issued, including three in 2023 alone. While these parking violations are primarily an inconvenience rather than a direct impact on resident safety or building conditions, they do indicate an ongoing accessibility issue for the property. The most recent building-related issues appear to have been resolved promptly, with no active violations or complaints currently on record. The property has maintained regular upkeep and improvements over the years, with the most significant renovation work being completed in 2014.

Risk rating

How 506-508 8Th 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, 1120 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.

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 73.1%
Moderate concern 17.7%
Severe concern 9.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
