Initial analysis

The property at 666-668 5th Avenue is a two-story multi-family residential duplex located in San Francisco's Inner Richmond neighborhood, built in 1907 and currently owned by the Eva So Po Choi Revocable Trust. The building has undergone several maintenance and improvement projects over the years, with the most recent significant work being a complete reroofing project in 2019 costing $9,000, along with a solar installation (25 PV modules with a 7.875 kW system) and service upgrade completed in August 2019. Historical records show consistent maintenance of the property, including earlier vinyl siding installations in 1998 and 1999, and a complete reroofing in 1996.

Of particular note is a housing inspection services complaint filed in December 2017 regarding the potential illegal rental of an additional unit, though this case is currently listed as not active. More recently, there was an incident of flooding on the property in November 2024 that required attention from PUC - Sewer Operations and has since been resolved. Various other municipal service calls have been logged for the address, including an abandoned vehicle report in February 2023, a general service request in April 2020, and a damaged parking meter report in November 2013, all of which have been resolved. The property's maintenance history suggests regular upkeep, with the most substantial improvements occurring between 2017-2019, including the installation of renewable energy systems, though the 2017 housing complaint may warrant continued monitoring of unit usage practices.

Risk rating

How 666-668 5Th 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

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.

Estimated permit spend (past 7 years)

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

Building permits, owner's portfolio

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

12-Month severity forecast
No violation 80.8%
Moderate concern 14.2%
Severe concern 5.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
